摘要
Abstract
Introduces the configuration,mechanical structure and operating conditions of the induced draft fan drive scheme of"steam&motor-driven feed"which has been realized in one Coal-fired power plant.The electrical principle of the system is described,and the parameter selection and boundary conditions of asynchronous motor are introduced;It also analyzes the stability of the system and how the motor,steam turbine and induced draft fan cooperate to realize power self-balance under various working conditions.The effect of the asynchronous motor on reducing the auxiliary power consumption rate and its influence on the voltage drop and short-circuit current of the medium voltage bus are calculated.This paper can provide some reference for the application of"steam&motor-driven feed"induced draft fan drive scheme in power plants in the future.关键词
