Energy-saving Applying Study of Fuzzy Control in the Variable Frequency and Constant Pressure Water Supply System
A new energy-saving method of variable frequency and constant pressure water supply system based on fuzzy control theory and software control technique is presented in this paper.Firstly,collecting the pipe network pressure periodically through the pressure sensor,the differential pressure signal will be sent into fuzzy controller after comparing the pipe network pressure with the set pressure.Then send a precise control quantity into the PID regulator to control output frequency of the frequency converter after a series of fuzzy arithmetic and solution of fuzzy arithmetic,so as to achieve the purpose of pump speed and consumed power controlling.The operating principle of variable frequency and constant pressure water supply system and the design procedures of software programming are elaborated.Practical application shows that the variable frequency and constant pressure water supply system based on fuzzy control has good effect on energy saving and obvious economic benefits and is worth popularizing and applying.
