山区日调节小水电站水能计算

Hydropower Energy Calculation for Small Daily Regulation Hydropower Stations in Mountainous Areas

针对日调节水电站水能计算方法按日平均流量计算日平均出力,忽略了日调节水库对径流的调节作用,不能充分体现日调节水库带来的发电效益这一问题,提出了山区日调节小水电站水能计算改进方法,并通过实例说明了计算方法和步骤。改进后的计算方法充分考虑了汛期日调节水库的调节作用,提高了水量利用率,较真实地反映了日调节水库的效益,为山区日调节水电站选择调节库容提供依据。

In traditional hydropower energy calculation method for daily regulation hydropower stations , the daily average output is calculated by the daily average water flow , while the daily regulation effect of the reservoirs and the regulation benefit are ignored.Thus, an improved calculation method is proposed for small daily regulation hydropower stations in mountainous areas .The calculation steps are illustrated by examples .In the improved method , the daily regulation effect of the reservoirs in flood season is considered and the regulation benefit is accurately reflected .It provides useful refer-ences for the selection of regulating capacity .
