摘　　要：针对径流预报误差给水电站水库发电调度带来的风险,在采用组合模型对月径流进行预报和优化调度计算的基础上,构建了水电站水库预报发电调度的模糊风险分析模型框架,并在对入库径流进行随机模拟的条件下设计了模糊风险分析模型的求解流程。三峡水电站水库的实例应用表明,预报误差在5、10月对发电调度的影响较大,且水电站在枯水期的发电模糊风险比汛期高。In view of the risk of generation scheduling of hydropower station reservoir caused by runoff prediction er- rors, based on the monthly runoff prediction with ensemble prediction model and optimization calculation of generation scheduling, the fuzzy risk analysis model framework of prediction generation scheduling of hydropower station is estab- lished. And then the solution process of the fuzzy risk analysis model is designed under the condition of reservoir runoff obtained by stochastic simulation. The case study of the Three Gorges Reservoir indicates that the runoff prediction errors have greater impacts on generation scheduling in May and October, and the generation fuzzy risk of dry season is much higher than that of flood season.
