Development of a Java-based optimization scheduling software for drainage pumping stations

Abstract

【Objective】 Improving efficiency and water flow rate is a criterion in designing pumping stations. This paper presents a software we developed to optimize the combination of running pumps and blade angles for drainage pumping stations that are equipped with fully adjustable axial (mixed) flow pumps. 【Method】 The software was developed using Java in the integrated environment IntelliJ IDE, with a universal visualization interface. It calculated water flow rate and flow resistance parameters of each pump, based on measured operating parameters, which include head and motor input powers, and performance curve of each pump. The software generated curves illustrating how the device efficiency changes with the blade angle. A dynamic programming model was established to optimize the operation and scheduling of the station, with the optimization objective to maximize the average device efficiency or total flow rate. This enables us to obtain an optimal combination of running pumps and blade angle for each running pump. 【Result】 The software was applied to some drainage pumping stations to graphically analyze the variation in device efficiency with blade angle (or flow rate). It provides optimized operation plans under different required flow rates when Hsy=5.3 m. When the required flow rate was 32 m3/s, the optimal scheme provided by the software improves the efficiency of the device by 0.76%, compared to the simple decision scheme for each running pump with a blade angle of +1.0°. 【Conclusion】 The software we developed is accurate and user - friendly. Practical applications showed that its performance is stable and can improve the operation and management of drainage pumping stations.
