Reseach on the Compensator for Power Factor in Force Commutated ReactivePower

介绍一种采用强迫换向交、直流变换器作为对电网基波无功功率进行补偿，提高功率因数的方法．设计了一种新型的四象限变流器，利用闭环微机控制系统，能够对基波无功功率进行补偿．交流电网的电流波形得到改善．

A method using force commutated reactivepower compensator to compensate for the fundamental reactivepower of source and to raise the power factor of source is introduced.A new type of four quadrant converter is designed and the analyses of current commutate during the thyristor commutate is presented.The design and the lab installation with microcomputer control system are described.It is proved through experiment that the presented method can fully compensate for the fundamental reactivepower of source and can also improve current waveform.
