摘　　要：为了提高配电网系统的电能质量,对无功功率进行精确补偿是非常有效的方法之一;本文研究了配电网静止同步补偿器用于无功补偿,并设计了单周控制的数字控制器;文中给出了基于单周控制的DSTATCOM无功补偿试验装置工作过程中的波形曲线,从试验结果可见,本文设计的单周控制DSTATCOM无功补偿装置的直流侧电容电压在工作过程中波动较小,装置发出或者吸收无功功率的动态响应速度较快,稳态补偿精度基本能够达到工程中无功补偿的要求。In order to improve the power quality of distribution network system,one of the most effective methods is reactive power compensation. In this paper,the Distribution Static Synchronous Compensator （DSTATCOM） for reactive power compensation was studied,and then the digital controller based on One-cycle control was designed. The waveforms of experimental device based on DSTATCOM of one-cycle control were given in this paper. It can be seen from the results that the fluctuation of DC capacitor voltage is lower,the dynamic response speed of DSTATCOM providing or absorbing reactive power is fast, and the accuracy of steady-state compensation can achieve the requirements of reactive power compensation in engineering basically.
