Economic Dispatch Control System of Cascade Hydropower Stations Based on a Universal Platform

To achieve the target of maximum energy reservation of cascade hydropower stations in the end of the calculation period,and in consideration of the constraints such as the joint vibration,an economic operation algorithm of cascade hydropower stations is determined,in which the starting-stopping of hydropower units and load distribution between hydropower stations are coordinated,improving the security,economy and real-time performance of real-time control of cascade hydropower stations.An economic dispatching control(EDC) software set of cascade hydropower stations based on the above algorithm and a universal platform for intelligent hydropower plant has been developed and successfully applied to the Songjianghe intelligent hydropower plant project.
