四川省峨眉县地方电网现有4座径流式小型水电站,总装机容量4,400kW。由于电网容量较小,峰荷时电站出力不足,低谷时电站又将弃水,故运行效益较差。为了解决这一问题,在兴建县网骨干电源小楔头水电站时,采用了扩大前池的作法,建成后运行效果良好。 Emei County, Sichuan Province, the local power grid 4 existing runoff small hydropower station with a total installed capacity of 4,400 kW. Due to the smaller capacity of the power grid, when the peak load is insufficient, the hydropower station will abandon the water when the trough is low, so the operating efficiency is poor. In order to solve this problem, in the construction of county backbone Wang Xiaogou hydropower station, the use of the expansion of the pool before the practice is completed and run well.
