黄河上游梯级水电站调度自动化系统AGC优化策略

AGC Optimization Strategy for the Dispatching Automation System of Cascade Hydropower Stations on Upper Yellow River

介绍了黄河上游梯级水电站调度自动化系统中自动发电控制(AGC)优化策略,以梯级消耗水能最小为目标函数,根据各水电站机组特性曲线,使用分阶段动态规划算法完成整个梯级系统的有功分配优化。该优化策略成功应用于黄河上游龙羊峡、李家峡、公伯峡梯级水电站,实践证明,算法可行且达到了预期优化目标。

The AGC optimization strategy for the dispatching automation system of the cascade hydropower stations on the upper Yellow River is introduced in detail. A model, with minimum cascade hydroenergy as its objective function, is established to optimize the power distribution of the whole cascade system by grading dynamic programming, according to the characteristic curves of the generators. The optimization strategy is applied to Longyangxia, Lijiaxia and Gongboxia cascade stations. The method is proved feasible and effective.
