Research on multi-objective optimal operation of water supply pump station based on water wave algorithm
In order to solve the problems of partial operation of pumps and frequent start-stop of units in water supply pumping stations,a multi-objective function of operating costs,total number of unit starts and stops and number of start-stop tasks of dispatchers in the scheduling cycle is established,and a mathematical model of pump station operation optimization constrained by pump speed regulation ratio,flow deviation and water supply demand is established.The multi-objective water wave algorithm is used to generate the Pareto solution set,and the multi-attribute decision research is carried out based on the CRITIC method to solve the multi-objective optimization and decision-making problem of pumping station.The engineering example shows that this method can solve the multi-objective comprehensive optimization problem of the parallel connection group of the water supply pumping station,and provide the dispatcher with a scheduling scheme with better comprehensive performance through the decision-making method,which is only 0.6%higher than the single target with the minimum operating cost,but reduces the number of 16 unit starts and stops and 4 start-stop tasks.The research results can effectively improve the operation safety and stability of the pump station while taking into account the operation cost,and extend the operation life of the pump,which can provide a reference for the optimization of the pump station.
