| Abstract:【Objective】According to the operation characteristics of inter-basin water transfer pump station,the safety requirements in the optimal operation of pump station are considered. 【Method】The nonlinear mathematical model of multi-objective optimization operation of pumping station was established with the minimum water extraction cost and the minimum flow unevenness between units in the station as the objectives, and the blade placement angle of each unit in each period of the water transfer cycle as the decision variable. A multi-objective genetic algorithm based on Pareto optimal solution theory was proposed.Taking Jiangdu No. 4 Station of the Eastern Route of South-to-North Water Diversion as an example, the typical calculation and analysis under different daily head and water lifting load were carried out considering the influence of peak-valley time-of-use price.【Results】Comprehensively considering the safety and economy of pumping station operation, under 100 %, 80 % and 60 % water lifting load, the water lifting cost per 104 m3 corresponding to the optimal operation scheme of the fourth Jiangdu Pumping Station is saved by 12.44 %, 14.26 % and 3.69 % on average compared with the conventional operation scheme, and the flow unevenness between units is significantly reduced compared with the scheme considering the economic operation target alone.【Conclusion】The research results can effectively reduce the safety hazards during the optimal operation of pumping stations, and provide reference for similar engineering operation management units. |
