Embodiment 2

[0062] In the present embodiment, the implementation process of the method of the present invention is specifically illustrated by taking the north-sending section of the river diverted from the Yangtze River to the Huaihe River Project as an example.

[0063] 1. Determine the objective function

[0064] The purpose of the objective function is to achieve the optimal distribution of head between cascade pumping stations while satisfying various equality and inequality constraints, so as to maximize the total efficiency of cascade pumping stations. The objective function of the 5-stage cascade pumping station is:

[0065]

[0066] In the formula: The flow rate of the cascade pump station in the k-th period is The total lift is H total The overall efficiency of the case; H total is the total head of the cascade pumping station; is the maximum efficiency of the jth stage pumping station.

[0067] 2. Determine the decision variables

[0068] The water level of the inl...

Description

technical field [0001] The invention relates to the field of water conservancy system optimization, in particular to a method for optimizing the head distribution of cascade pumping station groups based on the GA algorithm. Background technique [0002] In order to realize the rational allocation of water resources, many large-scale cross-basin, series-parallel cascade pumping station water diversion projects have been built at home and abroad. In these projects, the cascade pumping station system plays a huge role, but often due to the large installed capacity and high energy consumption, this type of system has high energy consumption in operation and has great potential for energy saving. [0003] The optimal scheduling of cascade pumping station group head has always been an important issue in the field of water conservancy system optimization. Scholars at home and abroad have done a lot of research and application on the optimal scheduling of cascade pumping station gr...
