瀑布沟水电站及下游梯级经济运行方式研究

Operation Mode Study of Pubugou Hydropower Station and Downstream Cascade Reservoirs

随着大渡河流域梯级水电站快速滚动开发,以瀑布沟为龙头水库的中下游梯级水库已经形成,其运行方式研究对提高梯级发电效益具有重要意义。以梯级水电站发电收入最大化为目标,建立了梯级联合优化调度模型,并以32年来水文资料和不同电力市场环境组合形成边界条件,模拟计算获得不同来水和市场环境下的一系列梯级水库优化调度方案。最后,总结出一般情况下,瀑布沟水库最佳运行方式的一般规律,指导瀑布沟水电站及下游梯级水库联合优化调度。

With the quick development of hydropower stations in Dadu River, the cascade hydropower stations and reservoirs are operated in the downstream of Pubugou Reservoir. It is important to study the optimum operation for improving the economic benefit of cascade hydropower stations. An optimum dispatching model is established herein for maximizing the generating income, and the model is solved under the combined boundary conditions of a series of 32 year inflow data and different power market environment. A series of cascade optimal dispatching solutions are finally obtained, and the general rules of optimum operation mode of Pubugou Reservoir are summarized in order to guide the dispatching of cascade hydropower stations.
