某抽水蓄能电站径流推求

Runoff Calculation of a Pumped Storage Power Station

如何在无资料地区推求径流成果,这是个较为困难的问题,目前主要是采用水文比拟法、降雨径流法等多种方法计算。笔者分别以金秀水文站、水晏水文站、中平水文站的径流成果为依据,采用水文比拟法(面积比加雨量修正)得出某抽水蓄能电站各坝址径流成果。经综合分析,最终选择水晏水文站为径流设计依据站,推求得出该电站各坝址径流成果,并进行合理性分析,为该电站的初期蓄水及运行提供可靠的径流成果。

How to calculate runoff results in areas without data is a relatively difficult problem. At present, it is mainly calculated by hydrological analogy method, rainfall runoff method and other methods. Based on the runoff results of Jinxiu Hydrologic Station, Shuiyan Hydrologic Station and Zhongping Hydrologic Station, the runoff results of each dam site of a pumped storage power station are obtained by hydrologic analogy method( area ratio plus rainfall correction). After comprehensive analysis, Shuiyan Hydrologic Station is finally selected as the runoff design basis station, and the runoff results of each dam site of the power station are calculated, and the rationality analysis is carried out to provide reliable runoff results for the initial filling and operation of the power station.
