刘家峡水电站尾水位抬高问题早已引起各方面的严重关注。因为它不仅降低了发电水头,损失大量电能,而且当宣泄特大洪水时,还担心尾水位可能高出尾水平台,影响电站安全运行。为此,有关单位曾进行过理论计算和试验研究。但是,由于受电站各泄水建筑物挑流和下游盐锅峡水库(以下简称盐库)回水等因 Liujiaxia hydropower station tail water level elevation has caused serious concern in all aspects. Because it not only reduces the generating head and loses a large amount of electric energy, but also when the catastrophic flood, it also fears that the tailrace level may be higher than the tailwater platform, affecting the safe operation of the power station. To this end, the relevant units have conducted theoretical calculations and experimental studies. However, due to the various power plants pick up the drainage structures and the downstream Yanghuoxia Reservoir (hereinafter referred to as the salt water) backwater and other factors
