10月6日下午，西藏自治(zhi)區當雄縣(xian)發生6.6級地震，羊湖抽水蓄能電(dian)廠(chang)、羊八井地熱電(dian)廠(chang)因距(ju)離震中格達(da)鄉較(jiao)近(jin)，受(shou)到一定(ding)影(ying)響(xiang)，但藏中電(dian)網運(yun)行(xing)正(zheng)常，電(dian)力供應基本穩定(ding)。
地震發生(sheng)后，國家(jia)電網公司第(di)一時間(jian)了解西藏電力有限公司損失情(qing)況，部署加強設備(bei)巡視，做(zuo)好抗震搶險工作。
國(guo)家電(dian)(dian)(dian)網西(xi)(xi)藏(zang)公司迅速組(zu)織所屬各(ge)單位(wei)人員對發(fa)(fa)供(gong)電(dian)(dian)(dian)設備(bei)、設施和建(jian)筑物進行巡視檢查，發(fa)(fa)現羊湖(hu)抽水(shui)(shui)蓄能電(dian)(dian)(dian)廠壓力(li)管道縱向移位(wei)11毫米，管道邊坡(po)有3處垮塌。為避免發(fa)(fa)生險情(qing)以致(zhi)影響藏(zang)中電(dian)(dian)(dian)網正常(chang)(chang)運(yun)行，西(xi)(xi)藏(zang)公司暫停羊湖(hu)電(dian)(dian)(dian)廠發(fa)(fa)電(dian)(dian)(dian)，并(bing)于(yu)19時15分至(zhi)22時55分之間，啟動了拉薩電(dian)(dian)(dian)網應(ying)急(ji)電(dian)(dian)(dian)源共4臺機組(zu)發(fa)(fa)電(dian)(dian)(dian)，同時將直孔水(shui)(shui)電(dian)(dian)(dian)廠調(diao)至(zhi)滿負荷運(yun)行，保證(zheng)了當晚(wan)用電(dian)(dian)(dian)高(gao)峰時段(duan)的正常(chang)(chang)電(dian)(dian)(dian)力(li)供(gong)應(ying)。此外，羊八(ba)井地(di)熱電(dian)(dian)(dian)廠一分廠廠房因地(di)震出現明顯裂紋，但發(fa)(fa)電(dian)(dian)(dian)設備(bei)運(yun)行正常(chang)(chang)。
為確保及(ji)時(shi)有(you)效應對(dui)地震(zhen)(zhen)造(zao)成的影響，預防災害再次襲(xi)來，國家電(dian)(dian)網西藏公(gong)司加強了(le)各電(dian)(dian)源點(dian)、變電(dian)(dian)站、輸電(dian)(dian)線路和廠區廠房等重點(dian)部位的巡(xun)視(shi)，要(yao)求(qiu)所屬各單位主要(yao)負責人到崗指揮抗震(zhen)(zhen)搶險。截至10月7日下午，藏中(zhong)電(dian)(dian)網除羊湖電(dian)(dian)廠外(wai)其(qi)他電(dian)(dian)源點(dian)及(ji)主網運行基本正(zheng)常，電(dian)(dian)力(li)供應基本能(neng)夠保證人民(min)生產生活需求(qiu)，未因地震(zhen)(zhen)災害而(er)拉閘(zha)限電(dian)(dian)。
