基于水化学法的蒲石河抽水蓄能电站渗漏研究

抽水蓄能电站水库渗漏问题不仅会降低其运行效益, 还会带来巨大的安全隐患, 有效识别其渗漏水源对保证 抽水蓄能电站安全、 高效运行具有重要意义。利用水体中 Cl - 、 SO 4 2- 、 NO 3 - 及 222 Rn 浓度研究了蒲石河抽水蓄能 电站下厂房渗漏水来源及比例。结果表明, 该抽水蓄能电站地下厂房渗漏水主要来自地表水, 底层量水堰 2 号、 3 号及顶层量水堰号渗漏水中含有地下水, 所占比例分别为 39 1 2%、 20%、 4%, 而顶层量水堰 1号、 5 号渗漏水全部来 自于地表水。本研究可有效应对蒲石河抽水蓄能电站地下厂房渗漏问题, 为保障抽水蓄能电站安全运行提供一定 的科学支撑。

Studying water leakage of Pushihe pumped storage power station based on water chemical method

Water leakage of pumped storage power stations can not only reduce operating efficiency, but also cause huge security risks. Identifica2 tion sources of leakage water have great importance to safe and efficient operation of pumped storage power stations. In this paper, we used water chemistry method to study sources and their proportion of leakage water of Pushihe Pumped Storage Power Station. The results show that the sources of leakage water mainly came from surface water. Leakage water of the bottom weir # 2, # 3 and the top water weir # 4 contained g roundwater, and the proportion was 39 1 2% , 20% , 4% respectively, while leakage water of the top weir # 1, # 5 all came from surface water. This study can deal with the leakage problem of Pushihe Pumped Storage Station effectively, therefore ensure safety operation of the station.
