摘要
电动机无功就地补偿技术虽然原理简单,但它却是在20世纪80年代末到90年代随着电力电容器技术的发展而蓬勃发展起来的[1]。随着电力电子技术和PWM技术的发展,有源电力滤波器(APF)是目前谐波抑制的一个重要发展趋势,但LC滤波器作为装设谐波补偿装置的传统方法仍是当前补偿谐波的主要手段[2]。本文对常见的无功补偿技术移相电容器无功补偿、静止无功补偿(SVC)及静止无功发生装置(SVG)与传统的谐波补偿装置、LC滤波器(LCF)及有源电力滤波器(APF)进行了分析比较。
Although the principle of vat compensation at locality is simplesy, the great development is gained by the technique of power capacitors from 80s to 90s in 20th century. With the development of power electronics techniques and pulse width modulation （PWM）, active power filter （APF） is an important trend in harmonics suppression currently. As a traditional method, LC filter （LCF）, however, is a main means to suppress harmonics. Familiar ways of var compensation such as shifting phase capacitors, static var compensation （SVC）, static vat generator （SVG）, and traditional harmonics suppression methods such as LC filter, APF are analyzed in this paper.
