摘　　要：扎拉水电站主要任务为发电,水库泥沙淤积问题较为严重将影响发电效益。为研究出能使水库长期有效发挥发电效益的排沙调度方式,根据水库水沙特点,研究了4种水库排沙运行调度方式,分别为不设排沙运行控制水位方案、设排沙运行控制水位方案、设排沙运行控制水位+短时间敞泄排沙方案和不设排沙运行控制水位+短时间敞泄排沙方案。结果表明:设排沙运行控制水位方案能在主要来沙期固定水位排沙,能较好地排沙并兼顾发电,是一种合理可行的排沙运行调度方式。研究成果可为同类型水电站泥沙调度提供参考。The main task of Zhala Hydropower Station is to generate electricity,and the problem of sediment accu-mulation in the reservoir is relatively serious.To study the sediment discharge scheduling methods that can effec-tively utilize the power generation benefits of reservoirs in the long term,four sediment discharge scheduling methods were studied based on the characteristics of reservoir water and sediment,such as no sediment discharge control wa-ter level scheme,sediment discharge control water level scheme,sediment discharge control water level plus short-term open discharge sediment scheme,and no sediment discharge control water level plus short-term open dis-charge sediment scheme.The results showed that the sediment discharge control water level scheme can fix the wa-ter level for sediment discharge during the main sediment season,which can effectively discharge sediment and gen-erate power.It is a reasonable and feasible operation and scheduling method for sediment discharge.The research results can provide a reference for sediment scheduling of similar hydropower stations.
