Exploration of Application of Inverter-fed Motor in Primary Air Fan of Thermal Power Plant

How to conduct technological transformation of existing coal-fired generator set in order to reduce power consumption and coal consumption is a very worthwhile research issue.Applying variable frequency control technology in fan and water pump is an important part of China's energy-saving technological transformation of power system.Currently high voltage variable frequency control technology has been widely used in energy conservation of thermal power generation.This paper mainly introduces the energy-saving principle and operation of variable frequency inverter-fed motor of thermal power plant,and explores variable frequency transformation program selection of primary air fan,as well as its practical application effects.
