The invention discloses a multi-objective optimization system and method based on a blade-adjustable multi-unit pump station, computer equipment and a storage medium. The system comprises a multi-target decomposition module which is used for receiving system parameters of a multi-unit pump station, constructing a multi-target optimization model and decomposing the multi-target optimization model into a single-target optimization sub-model 1 and a single-target optimization sub-model 2; the system further comprises a single-target solving module which is used for solving the single-target optimization sub-model 1 and outputting an optimization scheme set which is constructed by the minimum power consumption cost of pump station operation, the power consumption cost of pump station operation of each unit and the optimization process of the blade setting angle in each time period corresponding to the power consumption cost of the pump station operation of each unit; and solving the single-target optimization sub-model 2 in the optimization scheme set, and outputting the shortest adjustment duration of the blade setting angle. The multi-objective optimization system and method can reduce the operation power consumption cost of the pump station, reduce the adjustment accumulated duration of the blade setting angle of each unit, and have the advantages of reliable precision and high accuracy.
Description
technical field [0001] The invention relates to the technical field of optimal operation management of pumping stations of water diversion projects, in particular to a multi-objective optimization system, method, computer equipment and storage medium based on multi-unit pumping stations with adjustable blades. Background technique [0002] At present, due to the uneven distribution of water resources in time and space, the economic and social development of many areas has been restricted. As an important part of the cascade water transfer system, large-scale water supply pump stations with adjustable blades can relieve the water in the receiving area by completing regular and quantitative water transfer tasks. Spatial and temporal inequalities of resources have important socio-economic and ecological benefits. Due to the large number of units installed in this type of pumping station, the large flow rate of a single unit, and the long operating time, the operating energy con...
