近日，中國能(neng)建江(jiang)蘇院承擔設計的蘇州(zhou)(zhou)南(nan)部電(dian)網(wang)500千(qian)伏UPFC（統(tong)一(yi)潮流控(kong)(kong)制(zhi)器）示范工程(cheng)正式投運。該工程(cheng)是目前(qian)世(shi)界上(shang)電(dian)壓等(deng)級最(zui)(zui)(zui)高、容量最(zui)(zui)(zui)大(da)、控(kong)(kong)制(zhi)最(zui)(zui)(zui)復(fu)雜的UPFC工程(cheng)，也是世(shi)界上(shang)首個500千(qian)伏電(dian)壓等(deng)級的雙回線路(lu)UPFC工程(cheng)，將在(zai)世(shi)界范圍內首次(ci)實現500千(qian)伏電(dian)網(wang)電(dian)能(neng)流向的靈活、精準控(kong)(kong)制(zhi)，最(zui)(zui)(zui)大(da)可(ke)提升蘇州(zhou)(zhou)電(dian)網(wang)電(dian)能(neng)消納能(neng)力(li)約130萬(wan)千(qian)瓦。
據稱，該工程的(de)(de)投(tou)運，相當(dang)于給蘇州南(nan)部電(dian)(dian)(dian)(dian)(dian)(dian)網加裝了一個(ge)“智能(neng)(neng)導航(hang)系統”，實現(xian)了電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)的(de)(de)“無人駕駛”。蘇州是(shi)我國用電(dian)(dian)(dian)(dian)(dian)(dian)負荷最大的(de)(de)地(di)市，冬(dong)季(ji)枯水期，四川來的(de)(de)水電(dian)(dian)(dian)(dian)(dian)(dian)銳(rui)減，電(dian)(dian)(dian)(dian)(dian)(dian)力的(de)(de)主線(xian)路500千伏梅木線(xian)將處于過負荷狀(zhuang)態(tai)，地(di)區(qu)將面臨(lin)停(ting)電(dian)(dian)(dian)(dian)(dian)(dian)風險；安(an)裝UPFC后(hou)，它可(ke)以像電(dian)(dian)(dian)(dian)(dian)(dian)網的(de)(de)智能(neng)(neng)導航(hang)系統一樣，將電(dian)(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)由(you)自由(you)分布狀(zhuang)態(tai)轉變為精(jing)確受控狀(zhuang)態(tai)，智能(neng)(neng)匹配三(san)(san)條(tiao)交(jiao)(jiao)流(liu)(liu)通道輸(shu)電(dian)(dian)(dian)(dian)(dian)(dian)功率，實現(xian)了電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)的(de)(de)最優分布，提升(sheng)蘇南(nan)地(di)區(qu)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)力130萬千瓦(wa)。相比新(xin)建輸(shu)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)路等(deng)傳(chuan)統解(jie)決“擁堵”的(de)(de)方式(shi)，節約(yue)投(tou)資達6億元。當(dang)蘇南(nan)地(di)區(qu)出(chu)現(xian)大范圍電(dian)(dian)(dian)(dian)(dian)(dian)網故(gu)障時，UPFC可(ke)以提高(gao)三(san)(san)條(tiao)交(jiao)(jiao)流(liu)(liu)線(xian)路輸(shu)送功率總和，最大限度縮小事(shi)故(gu)造成的(de)(de)停(ting)電(dian)(dian)(dian)(dian)(dian)(dian)范圍。此外，UPFC還(huan)可(ke)有(you)效維持(chi)蘇南(nan)地(di)區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)壓水平(ping)，提高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)網安(an)全穩定運行水平(ping)。
