摘　　要：机组运行方式直接关系到电站发电效益。以乌东德左岸电站为研究对象,通过比较在同一水头、同一负荷下,不同开机台数运行方式时,机组过流量的大小,从而找出最优的开机运行方式。研究发现,在同一负荷下,开机台数越少,机组的过流量越低,水头也将随之增高,从而降低耗水率,提高发电效率,达到增发电量的目的。The operation mode of hydroelectric units directly affect the power generation efficiency of hydropower stations.Taking the left bank power plant in Wudongde Hydropower Station as an example,the optimal operation mode of the units is determined by comparing the flow of the units under different number of operated units while with the same water head and load.It found that under the same load,the fewer the number of operated units,the lower the flow,and the higher the water head.Thereby,the water consumption rate is reduced and the power generation efficiency is improved.Thus,the goal of increasing the electricity generation is achieved.
