摘要

本文研究了配电静态补偿器(D-STATCOM)在三相四线线非线性不平衡负载中压配电系统中对中性点电流、源及PCC电流谐波畸变的补偿、PCC电压的调节和不平衡电流波形的补偿。该控制算法基于同步参考系理论和PI控制器。将控制算法得到的参考电流信号在滞回带电流控制器中进行比较，以便更好地切换D-STATCOM。并对无D-STATCOM和有D-STATCOM的系统性能进行了分析和比较。该控制方法在11/0.4kv中压配电系统中得到了有效的无功补偿和谐波畸变缓解。利用MATLAB/SIMULINK进行了仿真。

VSI Based DSTATCOM for Compensating Nonlinear and Unbalanced Loads

This paper presents study of distribution static compensator (D-STATCOM) for compensation of neutral current, source&PCC current harmonic distortion, PCC voltage regulation and compensation of unbalanced current waveform for the three phase four wire nonlinear and unbalanced load medium voltage distribution system. The proposed control algorithm is developed based on synchronous reference frame theory with PI controller. The obtained reference current signal from control algorithm is compared in hysteresis band current controller for better switching of D-STATCOM. The performance of system without & with D-STATCOM is also analysed and compared. The proposed control method is implemented on 11/0.4kv medium voltage distribution system and it is provided effective compensation for reactive power and harmonic distortion mitigation. The simulation results are obtained using MATLAB/SIMULINK.
