10月6日下午，西藏自治(zhi)區當雄縣發(fa)生6.6級地震，羊(yang)湖抽水(shui)蓄能電(dian)(dian)廠、羊(yang)八井(jing)地熱(re)電(dian)(dian)廠因距離震中(zhong)格(ge)達鄉較近，受到一定(ding)(ding)影響，但藏中(zhong)電(dian)(dian)網運行正常，電(dian)(dian)力(li)供應基本穩定(ding)(ding)。
地震(zhen)發生(sheng)后，國家電網公司(si)第一(yi)時間了解西(xi)藏電力(li)有限公司(si)損(sun)失情(qing)況(kuang)，部署加強設(she)備(bei)巡(xun)視，做(zuo)好抗震(zhen)搶險(xian)工作(zuo)。
國家電(dian)(dian)(dian)網(wang)西藏公(gong)司迅速(su)組織所屬各(ge)單位人員對發供電(dian)(dian)(dian)設備、設施(shi)和建筑物進行巡視檢查，發現羊湖(hu)抽水蓄能電(dian)(dian)(dian)廠(chang)(chang)壓力管道(dao)縱向移(yi)位11毫米，管道(dao)邊(bian)坡有3處垮塌。為(wei)避(bi)免發生險(xian)情以致影響(xiang)藏中電(dian)(dian)(dian)網(wang)正常(chang)運(yun)行，西藏公(gong)司暫停羊湖(hu)電(dian)(dian)(dian)廠(chang)(chang)發電(dian)(dian)(dian)，并(bing)于19時(shi)15分至22時(shi)55分之間，啟(qi)動了(le)拉薩電(dian)(dian)(dian)網(wang)應急電(dian)(dian)(dian)源共(gong)4臺(tai)機組發電(dian)(dian)(dian)，同(tong)時(shi)將(jiang)直(zhi)孔水電(dian)(dian)(dian)廠(chang)(chang)調至滿負荷運(yun)行，保證了(le)當晚用電(dian)(dian)(dian)高峰時(shi)段的(de)正常(chang)電(dian)(dian)(dian)力供應。此外，羊八(ba)井(jing)地(di)(di)熱(re)電(dian)(dian)(dian)廠(chang)(chang)一分廠(chang)(chang)廠(chang)(chang)房因(yin)地(di)(di)震出現明顯裂紋，但(dan)發電(dian)(dian)(dian)設備運(yun)行正常(chang)。
為確保及(ji)時(shi)有效(xiao)應(ying)對(dui)地震(zhen)(zhen)造成的影(ying)響，預防災(zai)害(hai)再次襲來，國(guo)家電(dian)網西藏公(gong)司加強了(le)各電(dian)源點(dian)(dian)、變(bian)電(dian)站、輸電(dian)線路和廠(chang)區(qu)廠(chang)房等重點(dian)(dian)部位的巡(xun)視(shi)，要(yao)求所屬各單位主要(yao)負責人到(dao)崗指揮抗震(zhen)(zhen)搶險(xian)。截至10月7日下午，藏中電(dian)網除羊湖電(dian)廠(chang)外其他(ta)電(dian)源點(dian)(dian)及(ji)主網運行(xing)基本(ben)正常，電(dian)力供應(ying)基本(ben)能夠保證人民(min)生產生活需求，未因地震(zhen)(zhen)災(zai)害(hai)而拉(la)閘(zha)限電(dian)。
