摘要
Abstract
The paper proposed a direct power control strategy of PWM rectifier based on virtual flux orientation. The strategy controls active power and reactive power of PWM rectifier instead of active and reactive current components of traditional control methods and uses virtual flux orientation method for coordinate transformation, so as to improve dynamic performance and reliability of whole frequency-conversion speed-regulation system and reduce system cost. Besides, the strategy uses an estimate method of initial integration value of virtual flux to identify initial virtual flux, which would be subtracted from the integration value of virtual flux after PWM rectifier starting, so as to eliminate DC component in virtual flux. The Matlab simulation result verified validity of the strategy.关键词
