A method for optimizing operation of a tidal drainage pumping station under less than design standard rainfall

Abstract

The application discloses a kind of tidal drainage pump station optimization operation method under lower design standard rainfall, to encounter lower design standard rainstorm under city tidal drainage pump station drainage period in drainage power consumption fee minimum as goal, construct objective function, and add constraint condition to objective function, so that unit realizes safe operation and unit is under stable and efficient operation Drainage power consumption fee minimum, simultaneously by the real-time lift of pump station pumping flow under initial lift and hydrodynamic calculation water level successive approximation, as the basis for pump station flow calculation, realize the real-time accurate capture of each unit each time period lift, flow, efficiency when drainage pump station operates, improve the calculation precision of important parameters, i.e. lift, flow, efficiency when model is solved, and important parameters are coupled into genetic algorithm for mathematical model solving, obtain each time period each unit optimization operation scheme, i.e. blade setting angle combination, and city drainage pump station engineering optimization operation decision scheduling has important theoretical and practical significance.
