洪渡河沙坝石垭子梯级优化调度研究

Study on optimal dispatching of Shaba and Shiyazi cascade reservoirs on Hongdu River

对洪渡河中下游沙坝和石垭子电站的运行特性进行分析,考虑梯级水力、电力联系,在常规调度的基础上,采用动态规划算法、逐次逼近算法、大系统分解协调算法、等微增率算法进行优化调度,优化效果显著,实现水电站最优经济运行,为实际调度提供最佳的指导方案。

This paper analysised the operating characteristics of the Hongdu river sand dam in the middle and lower reaches and Shiyazi hydropower station. Considering the cascade hydraulic and electric power connection, on the basis of the conventional scheduling, the dynamic scheduling algorithm, the successive approximation algorithm, the large system decomposition coordination algorithm, the equal micro-increment rate algorithm are used to optimize the scheduling, the optimization effect is remarkable, the optimal economic operation of the hydropower station is realized, and the best guidance scheme is provided for the actual dispatch.
