A method and system for regulating a water supply pump of a technical water supply system

Abstract

The application relates to a kind of technical water supply system water supply pump's regulation, the method comprises: obtaining the characteristic data under each target air temperature from the historical operation data of generator set, obtaining the first cooling water flow corresponding to different load intervals of generator set according to characteristic data, and, based on cooling water flow estimation model, obtain the second cooling water flow corresponding to different load intervals of generator set under non-target air temperature, obtain the energy efficiency optimization control strategy of unit according to the first cooling water flow, the second cooling water flow and the hydraulic performance curve of water supply pump. Through the application, the problem of low safety in the operation process of water supply system is solved, and the energy efficiency optimization control strategy is obtained through historical operation data to adjust the unit operation frequency and power according to the actual operation condition, to prevent unreasonable unit operation frequency and power, leading to unsafe operation, and at the same time, the unit is adjusted based on the energy efficiency optimization control strategy, which can effectively improve the unit operation efficiency.
