“蓄電池備電+移動油機應急發電”是有市電區域最基本的基站后備動力保障配置方案。對于頻繁需要上站應急發電的基站疊加小功率太陽能系統,可大幅降低應急發電成本,并持續獲得電費節省,投資回報周期小于3年。傳統疊光方案存在太陽能利用不充分、影響電池充電管理等問題,采用兼容太陽能輸入的開關電源系統疊光,可以低成本實現高收益。支持疊光的
通信電源系統有利于在運維期間動態調整配置,針對應急發電上站次數較多的基站實施疊光,能最小化疊光投資,在提高動力保障的同時長期節省電費和應急發電成本。
一、電池和應急發電問題多,成為斷站因素
隨著互聯網快速發展,人們生活已經離不開網絡,需要無處不在的移動寬帶;痉定運行是通信網絡高可用的基礎,由于停電不可避免,基站需要有合理的后備動力保障方案。蓄電池+移動油機是最常用的后備動力保障方式,停電時由蓄電池支持基站工作,當蓄電池容量不足時,調派移動油機上站發電,保障基站運行不中斷。
由于居民對噪聲的普遍反對,以及站點所在建筑物出入管理原因,實際上城市站點很難上站應急發電;農村站點發電距離遠、高山站上站困難,應急發電保障度困難。通過對基站通信中斷原因分析,平均57%網絡中斷與基站配套相關,停電是引起網絡中斷的要因。
以某市某運營商3453個站點為例,高山站無法應急發電的有195個,業主原因經常無法上站發電的有2004個,無法用移動油機保障的站點占比高達64%。該運營商單月停電2771站次,由于停電原因發生斷站1923次,停電斷站率高達69%。停電斷站涉及1322站點,平均每站斷站時長高達2.1小時。應急發電次數802次,停電發電比例29%,其中包括40次應急發電不及時導致基站運行中斷。由此可見,停電后不能應急發電或應急發電不及時是造成通信網絡中斷的因素。
二、蓄電池+移動油機,后備動力保障成本很高
在基站容量一定的條件下,蓄電池容量取決于后備時長要求,后備時長必須大于應急發電上站時間,并留有足夠的余量。對于頻繁停電的基站,如果具備小型固定油機安裝條件,可安裝固定油機,不具備固定油機安裝條件的基站,適當增配電池,如郊縣、農村、山區備電時長可分別增至5、7、10小時。對于通信負載平均功率為2kW的站點,備電7小時需要配置一組500Ah蓄電池,電池成本很高。移動油機作為應急保障電源,停電時安排發電人員上站發電,即使應急發電人員尚未到達站點時市電已恢復,也需要支付應急發電費用。
應急發電成本包括上站人工費用、發電油費、移動油機攤銷成本。上站人工費用與當地勞動力成本相關,一般在300元/次左右;發電燃油成本與發電時長、耗油率相關,一般平均每次發電消耗50元左右燃油;移動油機攤銷成本包括油機折舊、油機維護成本分攤,平均每次發電分攤30元左右。農村站點是停電高發區域,平均月上站次數可能超過一次,按應急發電成本每次380元計,如果每月發電一次,每年單站應急發電成本4560元,發電成本很高。
減少停電斷站、提高通信網絡質量是通信動力系統建設與維護的要務。不論是增配蓄電池延長備電時長、提高應急上站發電次數、安裝固定油機等,都可以降低停電斷站率,提高通信網絡質量。由于蓄電池成本很高,增加1小時備電時長平均每站每年需要投入400元左右;每增加1次應急上站發電需增加380元左右;安裝固定油機一次性投入成本很高。不論是電信運營商還是鐵塔運營商,都需要有以較低成本提高保障質量的解決方案。
三、站點疊光,低成本提高供電質量、降低運維成本中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜
站點疊光方案,指在站點電源基礎上疊加太陽能,安裝僅滿足通信負載功率需求的太陽能電池板,優先使用太陽能供電的方案。太陽能是可再生能源典型代表,疊加太陽能可降低站點電費。例如,對于平均直流負載功率為2kW的站點,假設日照時數為4小時(全國省會城市貴陽最低2.84小時、拉薩最高6.7小時,一半以上超過4小時),采用疊光方案可年省電2920度,需要安裝約2.5kWp的太陽能電池板?蛻舨少徧柲茈姵匕、太陽能模塊及其安裝服務成本為22000元,如果電價為1元/度,則疊光方案的投資回報周期為7.5年左右,決策投資相對困難。
疊光后,如果基站停電發生在有日照的時段,可以不需要應急發電。由于深夜通信業務較少、夜晚上站發電相對危險等因素,實際很少夜間發電。此外,由于移動油機普遍不防雨且室內發電危險,雨天一般也不發電。因此,應急發電多在沒有下雨的白天進行,該時間段太陽能可用概率很高,即使陰天太陽能發電量很少,也可延長電池備電時長。經過測算,采用疊光方案的站點,可以減少80%以上上站應急發電成本,并降低由于應急發電不及時帶來的斷站風險。
例如,某市某運營商共432個基站,2014年12月份發電77次,只有一次為夜間發電,發電次數TOP 10基站平均發電15.64小時,平均發電次數3.8次,最長一次發電時長僅5.42小時,發電時長相對平均。在相同應急保障條件下,對于應急發電TOP 10站點具備安裝太陽能電池板條件的,可采用疊光措施,假定減少應急發電次數比例為80%,單站一個月可以節省上站費用1155元。由于12月份并非停電高峰,評估單站一年可節省1.4萬元以上發電費用,遠比省電價值更大,投資回報周期僅1.3年左右。如果批量采用疊光方案,還可能獲得國家和地方政府財政補貼,如浙江省對于太陽能發電量每度補貼0.42元,可以進一步降低投資回報周期。由于應急發電成本以人工費用為主,人工費用呈長期上升趨勢,隨著應用時間的增加,疊光方案回報越來越高。
3~5年是合理的投資回報周期,按示例,疊光方案總投資2.2萬元,只要每年節省超過4400元,就值得投資。一個2kW站點年省電按2920元計,只需要能年節省1480元應急發電費用即可滿足5年投資回報要求。按每次發電成本380元計,對于年上站應急發電需求4次以上的站點,都值得投資疊光方案。如果太陽能發電可獲得補貼,如0.42元/度,每年補貼1226元,加之站點都或多或少存在應急發電需求,對所有具備安裝太陽能條件的站點普遍疊光,會具備非常好的投資回報。一個單運營商2G/4G站點或兩個運營商單制式共享站典型負載平均功率接近2kW,可配置一個3kW太陽能模塊和9×250Wp太陽能電池板,只需要凈占地面積13平米。當安裝面積不足時,可以欠配安裝,如只安裝1.5kW太陽能電池板,停電時不足的功率由電池補充,使原來只能備電3小時的站點(300Ah電池)在陽光較好時備電時長延長至12小時以上,同樣能大幅減少應急發電次數。
四、傳統疊光方案,電池管理風險需要謹慎控制
傳統疊光方案指在站點內增加一套獨立的太陽能系統,太陽能模塊輸出的直流電直接與存量開關電源直流輸出并聯,太陽能系統與開關電源互相獨立。由于需要優先使用太陽能,太陽能系統輸出的開路電壓應高于開關電源。對于傳統疊光方案來說,太陽能系統輸出電壓設置非常關鍵,不合適的設置會導致部分甚至全部太陽能被浪費。當開關電源或太陽能系統電壓測量電路出現偏差時,也可能發生同樣的結果。此外,開關電源均充時,由于電源輸出電壓更高,這段時間內太陽能無法被利用。
開關電源具備蓄電池管理功能,能限制最大充電電流以保護蓄電池使用壽命。當太陽能系統輸出電壓高于設置值時,過高的電壓使電池過充。由于疊加的太陽能功率大于負載功率是常態,在蓄電池需要充電時,多余的太陽能功率也會對電池進行充電,使電池充電電流大于開關電源設定的充電限流值,蓄電池實際充電電流與開關電源系統測量值不一致,不利于蓄電池充電管理。
開關電源都有溫度補償功能,電池溫度補償范圍為±2V,由于開關電源溫度補償功能無法與太陽能系統關聯,溫度降低時電源浮充電壓升高,導致太陽能浪費,而溫度升高時太陽能輸出電壓不變,使電池加速充電失水。如果取消開關電源溫度補償功能,太陽能可以得到充分應用,但會影響蓄電池使用壽命。
為了充分利用太陽能,保護電池壽命,對于傳統疊光方案需要準確配置太陽能電池板數量,謹慎設置太陽能系統和開關電源電壓,并取消電池溫度補償功能,在溫度變化不大的室內站點使用。
五、電源兼容太陽能,消除電池管理風險
隨著電力電子技術與數字信息技術融合發展,電源模塊控制芯片內含軟件和算法,使硬件功能可由軟件定義,稱為軟電源(SDP,Software Defined Power),可以很方便地實現不同功能模塊兼容。太陽能模塊與整流模塊兼容就是典型的軟電源特性,采用兼容太陽能的開關電源系統,就能在任何合適的站點在電源模塊位置插入太陽能模塊,不需要采購獨立的太陽能控制系統,除了太陽能電池板采購及安裝費用外,只需要從開關電源廠家購買一個太陽能模塊即可。
由于太陽能模塊與整流模塊兼容,通過同一個監控模塊控制,不論太陽能功率大小,也不論蓄電池需求電壓高或低,都會優先調度使用太陽能,使太陽能全部得到利用。太陽能模塊和整流模塊的輸出電壓統一控制,并與中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜電池溫度補償同步,蓄電池充放電管理功能完全不受影響。山西鐵塔聯合華為試點MTS站點電源疊光,疊光工程量就是安裝太陽能電池板的工作量,系統不需要調試就成功投產。因此,部署站點時宜優選支持疊光功能的電源系統,引導全行業電源向多功能兼容方向發展。對于存量宜疊光站點,如果存量電源不是高效電源且無法直接替換高效模塊,優先采用多功能高效電源改造。
六、應急發電TOP N管理,實現低成本疊光
由于站點規劃建設時很難預測未來應急發電情況,對于投產后的站點可以采用基于短板改進的應急發電次數TOP N管理手段,通過站點網管系統對應急發電次數進行統計,選擇應急發電次數多、合適安裝太陽能電池板的站點進行疊光,可以實現精準配置,最小化疊光成本。如山西試點的疊光站點就是停電次數較多的站點,經測算,站點疊光年收益高達2.1萬元/年,非?捎^。
如果全面采用支持疊光的電源系統,定期對區域內基站應急發電次數TOP N站點進行疊光、疊油(不具備安裝太陽能條件,但可安裝固定油機的)、疊電(對于不能疊光、疊油的站點,可直接增配新電池或鋰電池)等手段優化,逐漸消滅需要頻繁應急發電的站點,大幅度減少應急發電上站次數,降低應急發電成本,并在節能的同時提高基站可靠性。到目前為止,疊光是以較低成本實現站點供電高保障的首選方案。
"Battery preparation +
mobile oil engine emergency power generation" is the most basic backup power support configuration of base station in the city. For the base stations that frequently need to go to the station for emergency power generation, the small power solar system can be superimposed, and the cost of emergency power generation can be greatly reduced, and the electricity cost will be continuously saved. The investment return cycle is less than 3 years. Traditional stacking scheme has many problems, such as inadequate solar energy utilization and influence on battery charging management. The switching power supply system compatible with solar input can achieve high cost at low cost. The communication power supply system supporting stacking light is conducive to dynamically adjusting the configuration during operation and maintenance. It can reduce the cost of light investment for the base stations which are more frequent on the basis of emergency power generation, and minimize power overlay investment. At the same time, it can save electricity and emergency power generation cost at the same time.
One, battery and emergency power generation problem, become the first factor of fault station
With the rapid development of the Internet, people can not live without the network, and it needs ubiquitous mobile broadband. The stable operation of the base station is the foundation of the high availability of the communication network. Because of the inevitable blackout, the base station needs a reasonable backup power support scheme. Battery + mobile oil machine is the most commonly used backup power support mode. When the power fails, the battery will support the base station. When the battery capacity is insufficient, the mobile oil station will be dispatched to the station to generate electricity, so that the base station will run without interruption.
Because of the widespread opposition to noise and the reasons for the access and management of buildings in the site, it is very difficult for the urban station to go to the station for emergency power generation. The rural station is far away from the power station, and the station on the high m中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜ountain station is difficult, and the emergency generation support is difficult. Through the analysis of the reason for the interruption of the base station communication, the average 57% network interruption is related to the base station, and the blackout is the first cause of the network interruption.
Take 3453 operators of a certain city as an example, there are 195 stations that can't generate electricity by emergency at Gaoshan station, and 2004 of them cannot afford to go to station because of owners' reasons. The proportion of stations that cannot be protected by mobile oil machine is 64%. The operator single month outage 2771 times, due to power outages cause broken station 1923 times, power station fault rate is as high as 69%. The blackout station involves 1322 stations, and the average height of each station is up to 2.1 hours. Emergency power generation 802 times, power generation ratio of 29%, including 40 emergency power generation is not timely lead to the base station operation interruption. So it can be seen that the failure of emergency power generation or emergency power generation after blackout is the first factor that causes the interruption of the communication network.
Two. Battery + mobile oil machine, the cost of backup power is very high
Under the condition of certain capacity of the base station, the capacity of the battery depends on the reserve time requirement, and the reserve time must be larger than the emergency power generation time, leaving enough margin. The base station for the frequent power outages, if you have a small fixed oil machine installation conditions, can be installed and fixed oil machine, do not have the conditions of fixed base station installation of machine oil, properly equipped with batteries, such as suburban, rural and mountainous areas by time can be increased to 5, 7, 10 hours. For a station with an average power of 2kW for the communication load, a set of 500Ah batteries should be configured for 7 hours, and the cost of the battery is very high. The mobile oil as an emergency power supply, when the power is cut off, the generator will be sent to the station to generate electricity. Even if the emergency generator has not arrived at the site, the electricity has been recovered, and the emergency power generation cost should be paid.
The cost of emergency power generation includes the labor cost of the station, the cost of power generation oil, and the amortization cost of the mobile oil machine. On labor costs associated with local labor costs, generally about 300 yuan / times; the cost of fuel and power generation time, fuel consumption rate, the average power consumption per 50 yuan fuel; mobile oil machine including machine depreciation, amortization cost of oil and oil machine maintenance costs, the average power allocation of 30 yuan. The rural station is a high power failure area. The number of stations on average may exceed one time per month. According to the emergency power generation cost, 380 yuan per time. If the electricity is generated once a month, the annual single station emergency power generation cost is 4560 yuan, and the cost of generating electricity is very high.
中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜the high cost of battery, the increase of 1 hours, the average power consumption time is about 400 yuan per station per year. For every 1 increase, the power generation for emergency stations needs to increase by about 380 yuan, and the cost of installing fixed oil units is high. Both telecom operators and tower operators need solutions to improve the quality of the guarantee at a lower cost.
Three, site stacking, low cost to improve the quality of power supply and reduce operation and maintenance costs
The site overlay scheme refers to the solar panels that are installed on the site power supply and only meet the power demand of communication load. Solar energy is a typical representative of renewable energy, and the superposition of solar energy can reduce the electricity cost of the site. For example, the average DC load power for the 2kW site, assuming the sunshine hours for 4 hours (the capital city of Guiyang, Lhasa's highest minimum 2.84 hours 6.7 hours, more than half of more than 4 hours), the scheme can stack light annual saving 2920, need to install about 2.5kWp solar panel. The cost of customer purchasing solar panels, solar modules and installation services is 22000 yuan. If the electricity price is 1 yuan / degree, the investment return period of the scheme is about 7.5 years, making investment decisions relatively difficult.
After stack light, if the base station blackout occurs in the period of sunshine, there is no need for emergency power generation. Because of the low night communication service, the night is on the station。
數據中心是我國實施“互聯網+”的重要基礎設施載體。相關統計顯示,截至2014年年底全國共規劃建設數據中心310個,已投入使用230個,其中約有三分之一為大型數據中心。另據數據中心產業聯盟發布的《數據中心產業發展白皮書》顯示,2011~2016年我國數據中心總投資將超過1萬億元。其中高低壓供配電、不間斷電源、制冷系統等配套設施造價在基礎設施造價中所占比例約75%~80%。
大型數據中心建設熱潮來襲。然而,在大型數據中心的運營中,巨大的配電成本支出正在對運營商形成挑戰,同時配電單元往往占用大量面積,不利于數據中心的節能環保。因此,如何能夠在保證數據中心穩定運行的情況下,實現配電系統的革新,顯著降低配電成本成為業界關注的問題。正是在這一趨勢下,中壓型UPS開始興起。中壓型UPS能夠提高接近負荷中心的電壓等級,減少低壓配電環節,降低能耗。可以預見,隨著電信行業去電信化、減配增效的深入推進,中壓UP中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜S系統將迎來廣闊的市場前景。
大型數據中心低壓配電系統亟待革新
我國早期通信系統負有政治安全責任,通信網絡一旦中斷將追究相關方政治責任,所以我國通信系統中冗余配置較高,這從早期UPS和開關電源蓄電池組后備時間的不一致可見一斑。所以,在建設數據中心的供電系統時,為了保證系統安全可靠性,充分考慮設備配置和冗余。
目前大型數據中心園區或大型數據中心的供配電結構一般是引市電高壓(110kV)或中壓(35kV、10kV)到高壓配電室然后再分配給干式變壓器(轉成380V)并配置成套低壓配電系統,成套低壓配電系統中的饋電柜再通過密集母線或電纜分配電能到每個樓層的低壓配電柜,再分配到大型的UPS(如500kVA、600kVA),目前每套低壓配電系統一般最大配置到2000kVA,每套低壓系統最多帶兩套大容量的1+1型UPS系統或2N型UPS系統,這種從高壓配電系統-低壓配電系統-UPS的結構在早期中小型數據中心應用廣泛,但隨著數據中心單UPS系統配電容量的加大,這種配電結構存在諸多缺陷。
,投資浪費嚴重。單套低壓配電系統存在浪費投資、浪費機房空間、浪費密集母線等浪費現象。雖然也可以將變壓器配置在每個樓層,但是供配電結構沒有變化,隨著大型UPS的使用,每套2000kVA的低壓配電系統下掛2套600kVA(1+1)考慮充電電流及負載冗余后即滿。
第二,增加供配電等級,增加了安全隱患。在相同的電源器件環境中,對于配電系統來說上下游開關越少越安全,配電等級越少可靠性越高,接近負荷中心的電壓等級越高越節能。大型數據中心園區35kV開關站-10kV高壓配電柜-10kV配電柜-變壓器-低壓配電柜-密集母線-樓層配電柜-UPS系統,8層級的配電結構,每多1個層級則意味著增加一個故障隱患點。
第三,影響機房可使用面積,增加建筑成本。對于大型數據中心,如果每層樓均配置變壓器低壓配電室、UPS系統電源室,相應電源區域要預留40%以上的空間,對于通信機房來說,一般預留25%~30%空間,且低壓配電結構冗余度越大占機房面積越大。
中壓型一體化UPS正在興起
回顧通信領域的高低壓配電發展趨勢,交流系統從早期的380V到中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜10kV,不間斷電源從220V到240V、336V高壓直流,設備功耗密集程度越大配電系統的電壓等級也隨之上升,采用高壓等級的設備可以更多地減少線損、線纜母線投資、節省設備占地面積、減少轉換次數也意味著節能,同樣,改變傳統的380V進380V出220V配電的結構,提高UPS進入電壓等級至10kV以上也具備以上優點。使用如10kV的UPS的前提是將傳統低壓配點系統的計量功能、功率補償功能、低壓發電機組轉移到10kV系統。
低壓配電中的計量可采用高壓端計量。傳統數據中心往往是通過在低壓段低壓配電系統中配置計量柜的方式,但是隨著數據中心規模越來越大,大型數據中心已有10套以上的低壓配電系統,且分為生活用電、辦公用電等,統計量工作放在高壓將成為一種趨勢。采用高壓端計量的同時仍可以通過中壓型一體化UPS的變壓器的數據采集進行自動統計上報。
低壓配電中的補償功能可改為高壓補償和負荷中心就近補償。對于數據中心來說,感性負載和容性負載同時存在,感性負載主要為空調主機、風機等電機類設備;整流設備、IT設備為容性負載;也就說數據中心感性負載和容性負載是同時存在的,是相互補充的。統計顯示,目前大部分通信局樓的低壓電容器柜多設置為人工投入,因為由于感性負載和容性負載的同時存在,功率因數cosΦ通常都在0.92以上。采取在低壓配電系統進行補償屬于后補償,沒有起到有效作用,且在諧波環境下容易引發電容器共振并存在爆炸風險。因此未來的數據中心應針對具體機房環境測試其諧波和無功負荷情況進行就近補償。
大型數據中心采用高壓油機是必然趨勢。目前大型、超大型數據中心已推廣采用高壓油機,帶來很多優勢:電纜、上下游開關配置方面,簡化了配電結構,高壓油機使用高壓電纜傳輸電力,高壓輸電電流相當于低壓輸電電流的二十六分之一,上下游開關及電纜投資節省、敷設及施工方便、線損很小、安全性也較高;便于進行多機并機,形成大容量后備電源,消除了常壓油機系統面臨的輸出容量瓶頸;若采用高壓空調必須采用高壓油機,離心機組啟動電流較大,如國內某運營商集團企業標準規定“除變頻供電的電動機外,單臺額定功率大于350kW 的電動機,宜采用10kV 電源供電”。采用高壓冷水機組供電后,可以相應減少變壓器及低配和密集母線、電纜的投資,綜合對比高壓冷水機組的價格因素,初步統計可以節省0.075萬元/kW(制冷量);高壓油機集中布置,可以根據園區功耗發展情況分期、逐臺投資,而低壓油機則只能是與低配模塊化相匹配而無論油機的實際負載率,造成油機投資浪費;推廣使用高壓油機之后低壓配電系統中的ATS柜可以減配。
以上分析證明,低壓配電系統中的主要功能,計量、電容、ATS柜等都可以代替,實施高壓到負荷中心的二級轉換比再經過低壓側顯然可以節省更多成本,減少中間配電環節后也使得可靠性提高很多。
國外中壓UPS系統應用現狀
從歐洲地區的中壓UPS系統發展來看,中壓UPS系統多應用在工業級不間斷電源應用場景中,擁有兆瓦級額定功率和高達99.5%的中壓UPS,儲能和逆變器依然處于低壓水平,它還能大幅簡化維護作業和降低系統成本。中壓UPS可進行改造,進行定制化設計,可兼容各種各樣的儲能裝置,具體取決于所需的保護時間。超級電容器和飛輪可在幾秒鐘內提供高密度保護,而電池可以達到長達15分鐘的備用時間。
北美地區早期工業用中壓型UPS系統多為集裝箱式結構或露天箱體結構。數據中心使用的中壓型UPS系統多為戶內型、模塊化結構,容量為2.0MW~20MW。包括輸入輸出開關柜、變壓器箱、主控單元、PES柜(中壓)、雙向變流器、儲能箱等。戶外型儲能箱后備時間為1~3分鐘,戶內型后備時間根據客戶需求配置,可以達到30分鐘以上。
可以看到,國外已有類似產品,但是國外的中壓UPS較多定位于將UPS系統功能集中于中壓段解決,目前已在美國的部分大型數據中心開始應用。
尤為值得一提的是,相比傳統低壓UPS,中低壓一體化UPS在同樣的場景下將減少80%的投資成本,而之所以能夠帶來這一“不可思議”的改變,則主要得益于大幅減少了傳統低壓配電柜的占地面積,節省了大量的低壓配電母線、電纜,同時發電機組采用高壓油機也便于分期投資。可以預見,中壓UPS系統的建設將為運營商節省大量的供配電成本,進一步提升運營商的市場競爭力。
The data center is the implementation of the "critical infrastructure support Internet plus" in china. Statistics show that as of the end of 2014, 310 data centers were planned and built in China, and 230 of them had been put into operation, of which about 1/3 were large data centers. According to the data center industrial development white paper published by the data center industry alliance, the total investment of China's data center will exceed 1 trillion yuan in 2011~2016. The cost of high and low voltage supply and distribution, uninterrupted power supply, refrigeration system and other supporting facilities is about 75%~80% in the cost of infrastructure.
Large data center construction upsurge is coming. However, in the operation of large data centers, the huge distribution cost is challenging the operators. At the same time, the distribution units often occupy a large number of areas, which is not conducive to the energy saving and environmental protection of data centers. Therefore, how to ensure the stable operation of data center and realize the innovation of distribution system, significantly reduce the distribution cost has become the industry's concern. It is under this trend that medium voltage UPS is beginning to rise. The medium voltage UPS can improve the voltage level near the load center, reduce the low voltage distribution link and reduce the energy consumption. It is foreseeable that the medium voltage UPS system will usher in a broad market prospect as the telecom industry goes to the telecommunication industry, the reduction and the increase of efficiency.
The low voltage distribution system in large data center needs to be innovated urgently
China's early communication system bears the responsibility of political security. Once the interruption of communication network is concerned, the related party's political responsibilities will be investigated. So the redundancy allocation in China's communication system is relatively high, which is evident from the inconsistency between the early UPS and the reserve time of the switching power battery group. Therefore, in building the power supply system of the data center, in order to ensure the safety and reliability of the system, the configuration and redundancy of the equipment are fully considered.
The current power supply structure of large data center park or large data center is generally cited city electric pressure (110kV) or medium (35kV, 10kV) to the high voltage distribution room and then assigned to the dry-type transformer (to 380V) and the configuration of complete sets of low-voltage distribution system, complete sets of low-voltage distribution system cabinet system in the crowded bus cable or distribution of electric energy to low voltage power distribution cabinet on each floor, redistribution to large UPS (500kVA, 600kVA), the current at the low voltage distribution system general maximum configuration to 2000kVA, each with a maximum of two sets of low voltage system of large capacity 1+ 1 type UPS or type 2N UPS system, the structure of high voltage power distribution systems - from low voltage power distribution system -UPS in the early application of small data center, but with the increase of data center power distribution capacity of single UPS system, many defects of this distribution structure.
First, the waste of investment is serious. A single low voltage distribution system is wasteful of investment, waste of space, and waste of dense busbar. Although it is possible to transformer configuration on each floor, but no changes in the structure of power supply, with the use of large UPS, under the low voltage distribution system of each 2000kVA 2 600kVA (1+1) considering the charging current and the load is full of redundancy.
Second, increase the level of power supply and distribution, and increase the hidden danger of security. In the same power supply device environment, for the distribution system, the less the upstream and downstream switches are, the safer. The less the distribution level is, the higher the reliability. The higher the voltage level near the load center, the more energy saving. Large data center park 35kV switchgear, -10kV high voltage switchgear, -10kV distribution cabinet, transformer low voltage switchboard, dense busbar floor switchboard -UPS system, 8 tier power distribution structure, every 1 or more levels means adding a hidden danger point.
Third, it will affect the available area of the machine room and increase the cost of the building. For large data center, if every floor of the configuration of low-voltage distribution transformer chamber, UPS system power supply room, corresponding power area should set aside more than 40% space for communication room, usually reserved for the 25%~30% space, and the greater the redundancy structure of low voltage power distribution room for a larger area.
Medium voltage integrated UPS is on the rise
Review the development trend of high and low voltage power distribution communication field, AC system from 10kV to early 380V, uninterrupted power supply from 220V to 240V, 336V high voltage DC voltage, the greater the degree of power equipment intensive distribution system also increased, the voltage level of the equipment can reduce the line loss, more investment, save equipment floor bus cable area, reduce the number of transitions also means the same, energy saving, change the traditional 380V into 380V structure 220V distribution, improve the UPS into the voltage level to above 10kV have more advantages. The premise of using UPS such as 10kV is to transfer the metering function, power compensation function and low voltage generator to 10kV system.
中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜
High voltage end metering can be used in the measurement of low voltage distribution. The traditional data center is usually configured through metering cabinet at low pressure in the low voltage distribution system, but with the increasing scale of data center, large data center has more than 10 sets of low-voltage distribution system, and divided into electricity, electricity and other office work, statistics on the pressure will become a trend. At the same time, the data acquisition of the medium voltage integrated UPS transformer can be collected and reported automatically by the high voltage end measurement.
The compensation function in low voltage distribution can be changed to high voltage compensation and load center close compensation. For data centers, there is also the inductive and capacitive loads, inductive load mainly for air conditioner, fan motor equipment; rectification equipment, IT equipment for the capacitive load; also said data center of the inductive and capacitive loads exist at the same time, is complement each other. Statistics show that at present, most of the low voltage capacitor cabinet of the communication bureau building is set up。
“模范城市曼海姆(MOMA)”項目是由德國政府啟動的“未來能源系統”計劃的一部分。該項目通過在當地電網中部署先進的信息通信技術以及小型裝置,使消費者直接體驗可再生電能的波動使用特點。
MOMA電網將來自超過500個生產商供應的電力配送至曼海姆及毗鄰的德累斯頓市。電網本身兼作電力線寬帶系統,連接了大量家用智能設備。該項目始于2010年,至今已有1000名居民參加,這些居民的家電都連接到這個“能源互聯網”中,并利用眾多的軟件工具監控其電力使用和支出狀況。
MOMA首席執行官英戈 勛伯格(Ingo Schoenberg)表示:“可再生能源最大的挑戰是,時而有風,時而陽光普照,但當你需要的時候它們并不一定可用。MOMA項目尋求供求平衡的方法,力求在高波動性的能源發電和智慧的能源消耗之間取得平衡,并同時提高效率。”
勛伯格說:“通過將稅費與電網容量相連接,鼓勵項目參與者在能源可用性高、價格低的時候用電。對于那些不愿意自己調節設置的用戶,MOMA甚至制定了‘節能管家’幫助用戶在能量充足、價格便宜的時段打開電器。項目的運行狀況表明,當消費者知悉能源的真實價格時,自然會改變使用方式。”
在知識和技術的武裝下,私人用戶節約了10%左右的能耗和15%的能源費用,而電力運營商能夠更好地管理網絡負載。MOMA項目的成果為制定彈性電價、建立同時承載智能電網和智能電表的單一通信平臺提供了立法的依據。
高品質通信網絡助力電網升級
MOMA項目采用的技術解決方案也為電力供應商提供了解決電力中斷并提高運營效率的新方法。在美國,風暴和“小動物”嚴重破壞電力供應,加州大學伯克利分校2004年的一項研究表明,美國每年由停電造成的損失達到800億美元。
田納西州的查塔努加電力委員會為分布在約1500平方公里的居民提供電力服務。根據伯克利大學的數據計算,每年停電會對其服務區域造成約1億美元的損失,但該電力委員會并不是一個典型的美國能源供應商。
2012年,在美國能源部“復蘇法案”的11550萬美元的資金刺激下,查塔努加電力委員會完成了高度自動化的智能電網升級工作,為電網配備了智能傳感器、開關和儀表。與MOMA項目一樣,其電網以高品質的通信網絡為基礎,查塔努加電力委員會選擇了光纖寬帶網絡承載消費者三網合一的服務。
電力委員會執行副總裁大衛 韋德(David Wade)表示:“這應該就是未來電網的樣子,美國還沒有其它公共事業能夠達到如此高的自動化水平。但是,一切都取決于通信能力,查塔努加的電網與光纖網絡無縫銜接,這使得查塔努加成為實現我們未來設想的最佳場所。”
現在,在查塔努加,如果一輛汽車撞到了電線桿,電力委員會的電網將會進行“自我修復”。電網中的1200個智能開關可以通過光纖網絡確定電路中斷的位置,并改道供電。2月12日,查塔努加遭遇了20年來最嚴重的暴風雪,4萬名居民的供電自動恢復,其他3.6萬名居民的供電在工程師的幫助下,3天之內恢復正常。
中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜
電力委員會估計,以前恢復這7.6萬名居民的供電需要8天的時間。2012年以來,該區域的斷電事件減少了50%~60%,每年為當地減少了5000萬美元的支出。電力委員會自身也大大節約了成本:在維修、資產管理、上門服務以及盜竊方面,節約的成本高達1050萬美元。
自動化解決方案創建更加智能的電網
最終用戶的偷電行為仍然讓電力供應商頭疼不已,嚴重影響了利潤的獲取。華為,一家來自中國的技術公司,針對電力供應面對的新挑戰設計了不同的解決方案,既包括大規模的網絡基礎設施項目,也包括專門處理偷電等局部問題的核心平臺。
據華為介紹,尼日利亞的消費者偷電狀況尤其嚴重,供電商一直無法找出問題的原因,到目前為止,無法收集到準確的能耗數據的用戶數量超過了80%。
為了解決這個問題,華為正準備在尼日利亞安裝一個覆蓋40萬本地家庭的自動抄表系統,支持高速數據連接,同時部署新的傳感器和控制器。該系統部署完成后,客戶的電表將每15分鐘傳輸一次數據到當地運營商,從而使運營商獲得實時的用電數據。
華為企業BG Marketing與解決方案銷售部總裁何達炳說:“該系統將有效提高電力公司的營業額和利潤。即時通信系統和可靠的電力基礎設施維護是電力高效生產和配送的關鍵。其可以實現早期預警、實時故障定位、自我修復和有效負載管理等功能。”
隨著中國經濟的崛起,城市的蓬勃發展給傳統電網帶來了極大壓力。珠海電力局要為珠海市、淇澳島、橫琴島和高欄島的822萬居民供電。面對著各種接入、可靠性、成本和容量問題,傳統的固定和無線技術已經無法滿足業務要求,珠海電力局迫切需要提高網絡的自動化水平。
對于珠海電力局而言,在其服務區域安裝光纖電纜過于昂貴復雜。因此,其選擇了成本相對較低、但速度與光纖相似的華為4G LTE無線集群系統。與傳統雙向無線通信系統一樣,華為eLTE無線集群解決方案為珠海電力局提供了專用無線網絡,從而實現配電自動化通信。
同樣,在中國東部沿海城市青島,華為改造了阻礙電力性能的老舊線路和不可靠的通信網絡。華為全光xPON解決方案具備高度自動化的特點,幫助青島供電公司有效管理分布式供電,并提高網絡可靠性。
華為表示,通過利用網絡中的智能終端對數據進行實時監測,在數秒之內,就可以隔離故障線路,實現電網的自動修復,F在,青島供電公司每年停電時長減少了2.6小時,達到每戶1.1小時;每年電力損失下降了33.4兆千瓦時。
總而言之,為建立環境友好型社會,公用事業單位面臨著降低成本、優化運營以及遵守更加嚴格的規定等方面的壓力。為應對這些挑戰,華為等科技公司提供大量解決方案,從而創建更加智能的電網,最終提供更加環保的能源。
The "model city of Mannheim (MOMA) project by the German government launched the" future energy system is a part of the project ". By deploying advanced information and communication technology and small devices in the local power grid, the project directly enables consumers to experience the fluctuating characteristics of renewable energy.
MOMA grid will be from more than 500 manufacturers of power supply and distribution to the adjoining Dresden city of mannheim. The power grid itself is also a power line broadband system, which connects a large number of household intelligent equipment. The project began in 2010. Up to now, 1000 residents have participated. The household appliances are connected to the "energy Internet", and many software tools are used to monitor their electricity use and expenditure.中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜
Schoenberg, chief executive of MOMA, Ingo Schoenberg, said: "the biggest challenge of renewable energy is that sometimes it is windy and sunny. But when you need it, they are not always available. The MOMA project seeks a balanced supply and demand approach to achieve a balance between high volatility energy generation and intelligent energy consumption, and increase efficiency. "
"By connecting tax and electricity to power grid capacity," Schoenberg said, "project participants are encouraged to use electricity when they have high energy availability and low prices. For users who don't want to adjust their settings, MOMA even set up an energy-saving housekeeper to help users turn on electrical appliances at the time of energy sufficiency and cheap price. The operation of the project shows that when the consumer knows the real price of the energy, it will naturally change the way of use. "
Under the arming of knowledge and technology, private users save about 10% of energy consumption and 15% of energy costs, while electric power providers can better manage network load. The results of the MOMA project provide a legislative basis for the establishment of elastic electricity price, the establishment of a single communication platform carrying smart grid and intelligent electric meter.
High quality communication network upgrade power grid upgrading
The technical solutions adopted by the MOMA project also provide a new way for power suppliers to resolve power interruptions and improve operational efficiency. In the United States, storms and small animals seriously disrupt the power supply. A 2004 study by University of California at Berkeley showed that the annual loss caused by power cuts in the United States amounted to 80 billion dollars.
The Char Thanou Fagafaga Electric Power Commission in Tennessee provides electricity for residents of about 1500 square kilometers. According to the data from Berkeley University, the annual blackouts will cause about 100 million US dollars loss to the service area, but the Electric Power Commission is not a typical US energy supplier.
In 2012, under the stimulus of the US $115 million 500 thousand recovery program of the energy department, the Char Thanou Fagafaga Electric Power Commission completed highly automated upgrading of smart grid, which equipped smart sensors, switches and meters for the power grid. Like MOMA project, its power grid is based on high quality communication network. Char Thanou Fagafaga Electric Power Commission has chosen optical broadband network to load consumers' three networks in one service.
David Wade, executive vice president of the Electric Power Commission, said: "this should be the way of the future grid. No other utilities in the US can achieve such high automation level in the future." Wade said. But everything depends on communication capability. Char Thanou Fagafaga's power grid and optical fiber network seamlessly connect, which makes Char Thanou Fagafaga the best place to achieve our future vision.
Now, in Char Thanou Fagafaga, if a car hits a pole, the power Com中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜mittee's power grid will be "self repairing". 1200 smart switches in the power grid can determine the location of the interruption by the optical fiber network and switch to the power supply. In February 12th, Char Thanou Fagafaga suffered the most severe snowstorm in 20 years. The power supply of 40 thousand residents recovered automatically, and the power of 36 thousand other residents was restored to normal within 3 days with the help of engineers.
The Power Commission estimates that the restoration of electricity from the 76 thousand residents will take 8 days. Since 2012, power outages in the region have been reduced by 50%~60% and $50 million a year for local expenditure. The Power Commission itself has also greatly saved costs: the cost of saving up to $10 million 500 thousand in maintenance, asset management, door-to-door services and theft.
Automated solutions create more intelligent power grids
The end user's electricity theft still makes the power suppliers headache, seriously affecting the gain of profits. HUAWEI, a technology company from China, designed different solutions for the new challenges faced by the power supply, including large-scale network infrastructure projects, including the core platform for dealing with local issues such as stealing electricity.
According to HUAWEI, the situation of consumers stealing electricity in Nigeria is particularly serious. Power providers have been unable to find out the cause of the problem. Up to now, the number of users who can not collect accurate energy consumption data has exceeded 80%.
To solve this problem, HUAWEI is preparing to install an automatic meter reading system covering 400 thousand local families in Nigeria, which supports high-speed data connection, and deploys new sensors and controllers at the same time. After the system is deployed, the customer's meter will transmit data every 15 minutes to the local operator, enabling the operator to obtain real-time data on electricity.中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜
"The system will effectively improve the turnover and profit of the power company," said He Dabing, President of HUAWEI BG Marketing and the Sales Department of the solution. The key to efficient power production and distribution is the instant communication system and the reliable maintenance of the power infrastructure. It can realize early warning, real-time fault location, self repair and effective load 中興ZXDU58 W600 V4.5R01M01室外壁掛式電源柜
