考虑实际洪水过程的水电站能量指标复核研究

Study on Checking Energy Index for Hydropower Stations in Considering the Actual Flood Process

湖南镇电站自1980年投运以来,年平均发电量有5.15亿k W·h左右,不足其运行设计发电量(5.27亿k W·h)。分析其主要原因为:运行设计发电量的计算过程未考虑水库汛限水位、水库实际的洪水过程、电站设计调度图不够精细等。为此,绘制了新的水电站调度图,并完成了电站新的能量指标计算。

Hunanzhen hydropower station＇s annual output of power generation is 5.15 million k W·h, which is less than the design target 5.27 million k W·h. The main reasons was analyzied as follows： the design index without considering the flood control limit, the actual flood process and fine station dispatching map. Finally, the new dispatching map was completed by using new data, and it was applied to recalculate the new energy index of Hunanzhen hydropower station.
