东北电网水电站水能利用情况分析

Analysis on Water Energy Utilization for Hydraulic Power Station in Northeast Power Grid

由于每一座水电站的情况不同 ,用耗水率很难对各水电站之间的水能利用情况进行比较 ,本文用“水能利用效率”对东北电网水电站的水能利用情况进行比较和分析 ,1 1座水电站多年平均水能利用效率为 82 8% ,堤坝式水电站高于引水式和混合式水电站 。

Because the condition of each hydraulic power station differs,it is hard to make a comparison of water energy utilization among these hydraulic power stations by water consumption.This paper makes a comparison and analysis of water energy utilization among hydraulic power stations in northeast power grid by way of'water energy utilization efficiency'.For years,the average water energy utilization efficiency of 11 hydraulic power stations remains 82 8%.And the efficiency of dyke hydraulic power stations is higher than those of draining and hybrid hydraulic power stations.It provides an impersonal appraisal of water energy utilization of these hydraulic power stations.
