在(zai)南方(fang)電網公司的(de)積極(ji)推(tui)動(dong)和參與下(xia)，10月15日，廣東(dong)省政(zheng)(zheng)府舉行了應對(dui)西電東(dong)送通道故障應急演練(lian)演練(lian)。廣東(dong)省政(zheng)(zheng)府、省委(wei)宣傳部(bu)、省政(zheng)(zheng)府應急辦、南方(fang)監管局等(deng)18家單位(wei)，珠三角地區(qu)九個地市政(zheng)(zheng)府及相關單位(wei)、南方(fang)電網相關供電局等(deng)單位(wei)參加。
目前(qian)南方電(dian)(dian)(dian)(dian)網(wang)已經形成“八(ba)條(tiao)(tiao)交流(liu)、八(ba)條(tiao)(tiao)直(zhi)流(liu)”16條(tiao)(tiao)送電(dian)(dian)(dian)(dian)廣東(dong)的500千(qian)伏及(ji)以上大(da)(da)通道，最大(da)(da)輸送能力超過3400萬千(qian)瓦。電(dian)(dian)(dian)(dian)網(wang)運(yun)行(xing)模式更加復(fu)雜，給(gei)大(da)(da)電(dian)(dian)(dian)(dian)網(wang)運(yun)行(xing)控制帶來了(le)極大(da)(da)的挑戰，存在西電(dian)(dian)(dian)(dian)東(dong)送通道故(gu)障導致電(dian)(dian)(dian)(dian)網(wang)大(da)(da)面積停電(dian)(dian)(dian)(dian)風險(xian)。本次(ci)演練模擬了(le)西電(dian)(dian)(dian)(dian)東(dong)送通道500千(qian)伏溪洛渡送電(dian)(dian)(dian)(dian)廣東(dong)直(zhi)流(liu)工程雙(shuang)極四回閉鎖(suo)等一系列連鎖(suo)故(gu)障，導致西電(dian)(dian)(dian)(dian)通道全(quan)部斷開，造成廣東(dong)電(dian)(dian)(dian)(dian)網(wang)孤網(wang)運(yun)行(xing)等情況，相關部門(men)、參演單位密切配合，迅速判明事(shi)故(gu)原因，各級人(ren)員按照預案緊張有序地開展了(le)應急處置，及(ji)時恢(hui)復(fu)了(le)聯(lian)網(wang)線路(lu)供(gong)電(dian)(dian)(dian)(dian)。
在正(zheng)(zheng)式(shi)演(yan)練之前，廣東省政(zheng)府分(fen)別于9月(yue)19日(ri)和10月(yue)13日(ri)組織了(le)(le)(le)(le)2次預(yu)演(yan)，對(dui)故(gu)障過(guo)(guo)程中(zhong)(zhong)可能出現(xian)的(de)問題(ti)進(jin)行(xing)了(le)(le)(le)(le)充分(fen)的(de)預(yu)想，對(dui)事故(gu)處置過(guo)(guo)程中(zhong)(zhong)的(de)擬(ni)采(cai)取措施的(de)有效性進(jin)行(xing)了(le)(le)(le)(le)充分(fen)論證。通(tong)過(guo)(guo)預(yu)演(yan)及正(zheng)(zheng)式(shi)演(yan)練，進(jin)一步(bu)驗證了(le)(le)(le)(le)廣東各地(di)市、各部(bu)門與(yu)省政(zheng)府應(ying)急(ji)(ji)指(zhi)揮(hui)中(zhong)(zhong)心在重要事件節點對(dui)接的(de)合理性，檢(jian)驗了(le)(le)(le)(le)省應(ying)急(ji)(ji)指(zhi)揮(hui)中(zhong)(zhong)心與(yu)供(gong)電部(bu)門、各地(di)應(ying)急(ji)(ji)指(zhi)揮(hui)中(zhong)(zhong)心以及相關單(dan)位應(ying)急(ji)(ji)平臺連接的(de)通(tong)暢性。
