The Variable Frequency Speed Control Technique and Application on Fans and Pumps in Thermal Power Plants

Abstract

Abstract: The application of the variable frequency speed control technique in power plant became wide gradually along with deepening of energy saving and consumption reducing. The technique and energy saving principle of variable frequency speed control were produced. The energy-saving effectiveness of variable frequency speed control technique was analyzed according to the application instance of variable frequency reformation of power plant auxiliaries, and the problems needing attention in the technique reformation were pointed out.

Key words: thermal power plant, pump, fan, variable frequency speed control technique, energy saving, reformation
