By analyzing various characteristics of pump station operation, the ways to solve the economic operation of pump station are theoretically explored. Discusses the criteria and methods for optimal control of pump operating conditions. Using the similar theory of pump, the mathematical model of the optimal speed change of pump is derived. At the same time, discussed the problem of variable angle operation. The method of differential and dynamic programming is adopted for the optimal distribution of flow between pumping stations and the method of determining and combining the number of pumping stations is put forward. This method is suitable for various pumping station projects in water conservancy, industrial, urban water supply and drainage systems and is also theoretically applicable to the control of pumping station groups.
