摘要
论述了交流励磁发电技术原理,以及基于绝缘栅双极晶闸管(IGBT)的双宽频调制(PWM)变频器的设计,交流励磁系统对发电机有功和无功的独立调节能力,将显著提高电力系统的静态和暂态稳定性。随着电力电子技术的迅速发展,交流励磁技术必将广泛地应用于风电、小水电、抽水蓄能等变速发电领域。
The paper discusses the theoty of power generation technology with AC excitation and design of double-PWM converter based on IGBT.Because AC excitation system can regulate independently active power and reactive power of generator,static and transient stability of power system will be improved clearly.With the rapid development of power electronic technology,the technology with AC excitation will be applied to the field of velocity-varying generating.including wind power,small hydropower,pumped-storage power etc.
