Abstract

In the paper control of series active compensator, particularly dynamic voltage restorer (DVR), is considered. The compensator consists of VSI and an LC filter for smoothing VSI output voltage. Presence of the filter makes control of the compensator more difficult due to dynamics of a second order plant introduced by the filter which results in oscillations during a sudden voltage change. Multiloop controller is able to compensate the effect, however measurement of additional signals is needed. In the paper an estimator of the LC capacitor current is proposed in order to decrease total number of sensor needed for 3-ph DVR controller.
基于滤波电容电流估计的串联有源补偿器控制
本文研究了串联有源补偿器的控制问题,特别是动态电压恢复器的控制问题。补偿器由VSI和用于平滑VSI输出电压的LC滤波器组成。滤波器的存在使补偿器的控制变得更加困难,因为滤波器引入的二阶对象的动力学会在电压突然变化期间导致振荡。多环控制器能够补偿这种影响,但需要测量额外的信号。为了减少3-ph DVR控制器所需的传感器总数,本文提出了一种LC电容电流估计器。
