Research on Modeling of Water Supply System based on VVVF Speed Regulation
It is very important for optimal scheduling control, pump performance prediction and analysis to set up the model of water supply system. In this paper, the model of centrifugal pump water system, which is driven by three-phase asynchronous motor based on the vary voltage vary frequency (VVVF) speed regulation, is built combining the parameter expression of asynchronous motor mechanical property equation, the pump characteristic equation and dynamics knowledge. The simulation experiment platform is constructed, and the working characteristics of the water supply system are tested. It is concluded that the simulation results conform to the practical results, and that the proposed model is reliable and effective.
