介绍了沅水流域梯级电站开发状况,以梯级电站整体发电效益最大化为目标,统一制定了各水库运行方式的集中调度管理模式。对影响梯级电站运行效益的因素,如水库调节性能、电站调度权属、汛期水位控制、龙头水库运行方式以及电网需求与梯级电站优化运行之间的矛盾等进行了分析,阐述了集中调度实践及其产生的效益。
This paper introduces the development status of cascade hydropower stations in Yuanshui River Basin and aims at maximizing the overall power generation efficiency of cascaded hydropower stations. The central dispatch management mode of each reservoir operation mode has been formulated. The factors that affect the operating efficiency of cascade hydropower stations are analyzed, such as the performance of reservoir regulation, the ownership of power plant dispatch, the control of water level in flood season, the mode of operation of leading reservoirs and the contradiction between grid demand and optimal operation of cascade hydropower stations. The resulting benefits.
