Abstract: Taking the high voltage frequency conversion reformation for induced draft fan of the 600W unit in Sichuan Guang'an Power Generation Company Limited as example, starting form the control angle, the reformation scheme, the control strategy and the optimization method of the control strategy were expounded. The importance of design of advanced and rational control strategy in high voltage frequency conversion reformation of the induced draft fan was demonstrated.

Key words: induced draft fan (IDF), high voltage frequency conversion, reformation scheme, control strategy, optimization
