摘　　要：水电站多年平均年发电量是运行管理部门制定生产计划的重要依据。水电站建成投运后其边界条件、基础数据、调度运行方式等计算参数与设计阶段相比已发生变化,有必要复核其多年平均年发电量。以某水电站为例,分析了不同计算参数变化对其多年平均年发电量的影响程度,具体包括不同调度运行方式、不同电站出力系数、年内来水差异等,相关成果可供水库运行管理参考。The average annual power generation of hydropower stations is an important basis for operation and management departments to formulate production plans. After a hydropower station is completed and put into operation,its parameters,such as boundary condition,basic data and operation mode,may be different compared with that in design stage,so it is necessary to recheck its average annual electricity production. Taking a hydropower station as an example,the influence of different parameters on the average annual electricity generation is analyzed,including different operating methods,efficiency coefficient and yearly runoff difference. The results can provide references for reservoir operation and management.
