自动模式下的水电机组发电控制设计与实现

The Design and Implementation of the Generation Control for Hydropower Units in the Automatic Mode

针对提升大型水电站在电网中调峰调频作用及水电企业运行管控水平的需求,研究了自动模式下的水电机组发电控制技术,提出了负荷计划曲线斜率平滑启停模式下的提前开停机的算法流程。结合该启停模式提出了与一次调频协联控制策略以及异常处理策略,并基于丰满发电厂的应用实例验证了上述方法的有效性。可以得到合理选择提前开停机时间,可改善开停机过程的平滑效果。

In order to enhance the role of large hydropower plants in the grid for peak and frequency regulation and the operational control lev‐el of hydropower enterprises,the generation control technology of hydropower units in automatic mode is studied,and the algorithm process of early start-stop in the slope smoothing start-stop mode is proposed.The co-linked control strategy with primary frequency regulation and the exception handling strategy are proposed in combination with this start-stop mode,and the effectiveness of the above method is verified based on the application example of Fengman Power Plant.It can be concluded that the smoothing effect of the start-stop process can be im‐proved with the reasonable selection of the early start-stop time.
