Realization of automatic switchover from variable frequency operation to power frequency operation of fan and energy saving analysis

Abstract

Abstract: The implementation situation of variable frequency reformation of the three main fans (IDF, FDF and PAF) of Huadian Weifang Power Generation Company Limited was introduced. Through the dynamic test, the realization of automatic switchover from variable frequency operation to power frequency operation and automatic adjustment were expounded. The effects of variable frequency control, such as energy conservation and motor protection, were analyzed. By the variable frequency reformation of the three main fans, the house service consumption rate was greatly reduced, and better economical benefit was obtained.

Key words: automatic switchover from variable frequency operation to power frequency operation, trigger, corresponding function, hot test, energy conservation
