黄河拉西瓦水电站分期装机的探讨

Discussion on Installation of Generating Equipment in Stagesfor Laxiwa Hydroelectric Power Station on Yellow River

拉西瓦水电站是龙羊峡至青铜峡河段自上而下的第二个梯级,装机总规模6×700MW,从坝址径流、满足青海省用电需求、与下游梯级尼那水电站运行衔接及送电经济性等方面综合分析,在"南水北调"西线调水一期工程实施前,拉西瓦水电站装机容量可按2800MW考虑;西线调水一期实施后,根据市场需求,再确定后2台机组的安装进度。

Laxiwa Hydroelectric Power Station is the second hydropower project from upstream to downward on the Yellow River reach from Longyang Gorge to Qingtong Gorge with its total installed capacity of 6×700MW.In this paper installation of Laxiwa Hydroelectric Power Station generating equipment in stages has been studied.Through comprehensive analysis of the runoff at the hydroelectric power station dam sit,satisfying the power demand of Qinghai Province,hydraulic link with Nina Hydroelectric Power Station immediately downstream & economics of power transmisson,it is considered to install 2800MW at Laxiwa Hydroelectric Power Station before execution of the 'Water Transfer from South to North of Chain' Project the west route for the water diversion first stage works.After the first stage works of the west route are executed the rest 2 generating unit of Laxiwa Hydroelectric Power Station installation schedule will be determined according to the power market demand.
