Abstract
According to the principle of frequency conversion technology,the basic principle of energy-saving of the pumps with frequency conversion for speed regulation was demonstrated,so that it was concluded that the energy-saving effect of speed-control in pump station was superior to that of valve-control.A mathematical model of simple and practicable water supply system with frequency conversion for pressure regulation was derived by means of analysis and comparison between the existing control system and the control system with frequency conversion.
