近日，中國能(neng)(neng)建江(jiang)蘇院承擔設計的(de)蘇州南部(bu)電網(wang)500千(qian)伏UPFC（統一潮(chao)流(liu)控(kong)制器）示(shi)范(fan)工(gong)程正(zheng)式投運。該工(gong)程是(shi)目前世(shi)界上電壓等級(ji)最(zui)(zui)高(gao)、容量最(zui)(zui)大、控(kong)制最(zui)(zui)復雜的(de)UPFC工(gong)程，也是(shi)世(shi)界上首個500千(qian)伏電壓等級(ji)的(de)雙回線路UPFC工(gong)程，將在世(shi)界范(fan)圍(wei)內首次實現500千(qian)伏電網(wang)電能(neng)(neng)流(liu)向的(de)靈活、精準控(kong)制，最(zui)(zui)大可提升蘇州電網(wang)電能(neng)(neng)消納能(neng)(neng)力(li)約(yue)130萬千(qian)瓦。
據稱，該(gai)工程的(de)投(tou)運，相當(dang)于(yu)給(gei)蘇(su)(su)州南(nan)部(bu)電(dian)(dian)(dian)(dian)網(wang)加(jia)裝了一個“智能(neng)(neng)導航系統”，實現(xian)了電(dian)(dian)(dian)(dian)能(neng)(neng)的(de)“無人(ren)駕(jia)駛”。蘇(su)(su)州是我國用電(dian)(dian)(dian)(dian)負(fu)荷最(zui)大(da)的(de)地(di)(di)市，冬季枯水期，四川來的(de)水電(dian)(dian)(dian)(dian)銳減，電(dian)(dian)(dian)(dian)力的(de)主線(xian)(xian)路(lu)500千伏梅木線(xian)(xian)將處于(yu)過負(fu)荷狀態(tai)，地(di)(di)區(qu)(qu)將面臨停電(dian)(dian)(dian)(dian)風險；安(an)裝UPFC后，它可以(yi)像電(dian)(dian)(dian)(dian)網(wang)的(de)智能(neng)(neng)導航系統一樣(yang)，將電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)能(neng)(neng)由自由分布狀態(tai)轉變為精確受控狀態(tai)，智能(neng)(neng)匹配三(san)條(tiao)交(jiao)流通道輸(shu)電(dian)(dian)(dian)(dian)功(gong)率(lv)，實現(xian)了電(dian)(dian)(dian)(dian)能(neng)(neng)的(de)最(zui)優分布，提(ti)升蘇(su)(su)南(nan)地(di)(di)區(qu)(qu)供電(dian)(dian)(dian)(dian)能(neng)(neng)力130萬千瓦(wa)。相比新建輸(shu)電(dian)(dian)(dian)(dian)線(xian)(xian)路(lu)等傳統解決“擁堵”的(de)方式(shi)，節約投(tou)資(zi)達6億(yi)元。當(dang)蘇(su)(su)南(nan)地(di)(di)區(qu)(qu)出現(xian)大(da)范(fan)圍電(dian)(dian)(dian)(dian)網(wang)故(gu)(gu)障時，UPFC可以(yi)提(ti)高(gao)三(san)條(tiao)交(jiao)流線(xian)(xian)路(lu)輸(shu)送功(gong)率(lv)總和，最(zui)大(da)限(xian)度縮小事故(gu)(gu)造成(cheng)的(de)停電(dian)(dian)(dian)(dian)范(fan)圍。此外，UPFC還可有效維持蘇(su)(su)南(nan)地(di)(di)區(qu)(qu)電(dian)(dian)(dian)(dian)壓水平(ping)，提(ti)高(gao)電(dian)(dian)(dian)(dian)網(wang)安(an)全穩定運行(xing)水平(ping)。
