Application of dynamic programming successive approximation in blade-adjusting optimization of Jiangdu No. 3 Pumping Station

Jiangdu No.3 Pumping Station of the Eastern Route Project of South-to-North Water Diversion was taken as a study case.A mathematical model for the blade-adjusting optimization of multi-unit operation in a pumping station was established.The optimal combination schemes of the operating units and the blade angles at various stages were searched according to the minimum electricity consumption cost by use of the dynamic programming successive approximation method.The calculated results were validated by the experimental optimization method based on integral linear programming.A conclusion is drawn that the optimization results are reliable and the proposed method is feasible.
