昨天中午，位于駐馬店西平縣南13公里處的“駐馬店北500千伏變電站”正式帶電試運行，若經過24小時充電考驗，將正式投運。這是該省今年第一個建成的500千伏變電站項目，也是今年全省迎峰度夏重點工程之一。
 

　　據河南省電力公司介紹，該站去年8月開工，投運后不僅能滿足駐馬店遠期規劃網架以及駐馬店北部地區發展，也能優化220千伏電網結構，提高駐馬店供電區北部電網供電可靠性。
 

　　每年夏季用電(dian)(dian)(dian)(dian)(dian)高(gao)(gao)峰期(qi)，河南(nan)電(dian)(dian)(dian)(dian)(dian)網運行便經受(shou)考驗，特別是(shi)駐馬(ma)店(dian)、南(nan)陽(yang)、信陽(yang)等地。河南(nan)電(dian)(dian)(dian)(dian)(dian)力檢修公(gong)司余(yu)曉東說(shuo)，該(gai)站投(tou)運后(hou)，全省運行的500千伏(fu)(fu)變電(dian)(dian)(dian)(dian)(dian)站達到33個，“這意味著該(gai)省電(dian)(dian)(dian)(dian)(dian)網已由220千伏(fu)(fu)邁入500千伏(fu)(fu)時代。由于電(dian)(dian)(dian)(dian)(dian)壓等級高(gao)(gao)，就像(xiang)是(shi)一條(tiao)更(geng)大的‘河’，輸(shu)電(dian)(dian)(dian)(dian)(dian)距離長、電(dian)(dian)(dian)(dian)(dian)量大，而(er)且供電(dian)(dian)(dian)(dian)(dian)可靠性(xing)更(geng)高(gao)(gao)，不(bu)容(rong)易(yi)再發生(sheng)大面積停電(dian)(dian)(dian)(dian)(dian)事故(gu)”。
