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

In order to enhance the role of large hydropower plants in the grid for peak and frequency regulation and the operational control level 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 improved with the reasonable selection of the early start-stop time.
