Optimization of economic operation mode of pumping station-reservoir raw water transfer system
In order to improve the operating efficiency of the pumping station in the pumping station-reservoir raw water transfer system,the operating cost of the water transmission system must be mini-mized.By analyzing the characteristics of this type of water transmission system and water supply methods,a pump station unit flow distribution model was constructed based on the genetic algorithms to optimize the distribution of pump station operating flow.On this basis,considering the operation mode of the pumping station in the time dimension,combined with the engineering status of the Bozhou pressurized pumping station and the regional time-of-use electricity prices,an economic operation model was constructed with the minimum unit water lifting cost as the optimization goal.This method was applied to the Bozhou Water Supply Project,for which the results showed that the model effect was significant.The periodic water delivery volume in the historical operating interval was discretely calcu-lated,and the lowest unit water lifting cost during the period was obtained and subseguently analyzed.The results show that the constructed economic operation model has good applicability,which can re-duce the project operation cost and provide guidance for the optimal scheduling of the project.Depen-ding on the operating efficiency of the pumping station and the time-of-use electricity price,the unit water lifting cost of the pumping station first decreases and then increases with the increase in water transfer volume.
