金沙江下游梯级与三峡梯级枢纽联合蓄放水调度研究
Research on impounding dispatch for the lower cascade reservoir in Jinsha River and Three Gorges cascade
摘要
Abstract
To solve the competitive water storage problem of cascade reservoirs in the middle and up val⁃ley of the Yangtze River at the end of flood season, an impounding strategy of cascade reservoirs, which combines the impounding principle and the method of discriminant value of K,is proposed for judging the impounding time and the order of each reservoir in the premise for ensuring the safety of flood control. Im⁃pounding dispatch chart is drawn with impounding control lines of each reservoir which is got by simulating the flood regulating calculation for inflow at different frequencies in typical year. On this basis,a model of impounding dispatch based on the impounding dispatch chart in advance is developed. The proposed meth⁃od can be obviously accelerated by using the electromagnetism-like mechanism globe optimization algorithm. Compared with the original design scheme, the result indicates that the optimal scheme can improve the fill storage degrees for the cascade reservoirs,reduce discard water and optimize the economical benefits of power generation and navigation without any increase in river flood risk.关键词
