Multiple parallel centrifugal pumps units are often used in cascade high-lift pumping stations to achieve flow rate matching between stations. The optimal combinations of running pumps need to be determined during operation according to different required flow rate. Based on solving of pump operating parameters by the iterative method, taking the required flow as constraints and minimum total pumping power as objective function, the dynamic programming model was established to determine the optimal combinations of running pumps. For the mathematical model, a common software program was developed and applied to an actual project. The results showed that the calculation method was simple and effective, increasing flow matching rate and reducing energy consumption after operation optimization.
