摘要
提出了一种三相电压暂变补偿装置的主电路拓扑。该方案利用线电压对直流母线电容充电,扩大了补偿电压的范围。针对此方案对三相电压暂变进行独立补偿,采用了补偿装置的三角波比较控制方法,通过对比3种常见的控制策略的原理,最终给出了采用能量最优控制法系统的仿真结果和主电路补偿的实验结果。
One topology of three-phase voltage transient variation is proposed in this paper. The proposed scheme can extend the compensating depth with small filtering capacitances in the inverters because they are continuously charged by the residual line-to-line voltages. In order to achieve the respective compensation by the topolgy, there is triangle wave comparison method for control. Then, the basic theory of three kinds of control strategy is elaborated on.At last,the simulation and experimental results of system controled by energy optimal control are presented.
