Energy conservation using variable frequency drives of a humidification plant in a textile mill

Humidification plant in a textile industry is one of the major power consumers due to its continuous operation for maintaining required Relative Humidity (RH) and temperature of spinning plant to increase the quality of yarn. The traditional method of operation of induction motors in humidification plant was effective, but not energy efficient. To overcome this problem, the emerging trend is the widespread adoption of variable frequency drives (VFD) which can offer potential energy savings in a system by allowing continuous process of speed control. In this paper, modeling, simulation and performance analysis of `Open loop and closed loop speed control of induction motor using Variable frequency drive´ in MATLAB/Simulink and the Performance Verification of humidification plant in a textile industry where VFDs are installed very recently are presented.
