【摘要】 目前,水库优化调度研究常侧重于提高算法的精度和计算速度,而忽视了优化调度模型本身的合理性和准确性。如采用常数作出力系数进行水库优化调度计算往往误差较大。为此,根据水电站多年运行历史资料,推求不同发电水头下的综合耗水率,并将水电站综合耗水率应用于水库优化调度中。实例计算表明,所提出的计算方法更能反映水库实际运用情况。更多还原

【Abstract】 At present,improving the precision and computation speed of optimal operation model of reservoir has become essential;however the rationality and the veracity of the model are ignored.For example,some errors often occurred in the computation of reservoir optimal operation model because of using the efficiency coefficient of hydropower station as a constant.Therefore,this paper studies the water consumption rate of hydropower station and put it into reservoir optimal operation model computation in accordance with multiannual operation data of hydropower station.The results proved such method is more in keep with the actual operation situation of reservoir.更多还原
