隔河岩水电站是湖北省清江干流三个梯级水利枢纽中的第二个梯级,正常蓄水位时库容为34亿立方米,4台机组共120万千瓦,多年平均发电量为30.4亿千瓦时。电站位于长阳土家族自治县,距长江葛洲坝水电站60公里,为华中电网骨干电源,对电网的调峰、调频以及事故备用有着极为重要的作用。(一)提前发电,效益显著隔河岩水电站的主体工程1988年元月开工,1993年6月4日首台机组发电,比国家计划发电工期提前了6个月零25天。从电站蓄水验收和初期运行看,工程质
Geheyan Hydropower Station is the second of the three cascade water conservancy projects in the mainstream of Qingjiang River in Hubei Province. Its capacity is 3.4 billion cubic meters at normal water level, 1.2 million kW at 4 units and 3.04 billion kWh at many years . The power station is located in Changyang Tujia Autonomous County, 60 kilometers away from the Gezhouba Hydropower Station in the Yangtze River. It is a key power source for the Huazhong Power Grid and plays an extremely important role in peak regulation, frequency regulation and accident backup of the power grid. (I) Power generation in advance with significant benefits The main project of Geheyan Hydropower Station was started in January 1988 and the first generating unit was started on June 4, 1993, six months and 25 days ahead of the planned national power generation schedule. From the station acceptance and initial operation of water storage, the quality of the project
