小浪底、西霞院梯级水电站短期调峰调度研究

Study on short-term peak load of Xiaolangdi and Xixiayuan cascade hydropower stations

基于具有日调节性能的反调节水库的运行特点,提出西霞院水电站参与电网调峰的构想。通过建立小浪底、西霞院梯级水电站短期调峰模型,从理论和实际运行角度验证了西霞院参与调峰的可行性。根据不同的影响因子,制定了小浪底、西霞院短期调峰运行的可行方案。采用加速遗传算法求解各方案,结果表明:西霞院参与调峰运行能够大大提高水资源利用率和电站运行水平,实现电调与水调的双赢。

This papers proposes a concept of power grid peaking involved with Xixiayuan hydropower station that is a daily regulation reservoir with anti-regulation characteristics. The feasibility of such peaking was proved in both theoretical and actual operation aspects, through developing a short-term peaking model for the Xiaolangdi and Xixiayuan cascade plants. Feasible schemes of short-term peaking for these stations were formulated using different impact factors, and they were solved with an accelerating genetic algorithm. The calculations show that the efficiency of water use and power generation can be greatly increased by this peaking technique. Thus, the win-win between power grid dispatching and water dispatching comes true.
