摘要

本文提出了一种最优线性二次高斯(LQG)控制方案，用于单区域电力系统中自动电压调节器(AVR)的鲁棒控制。为了提高系统的超调阻尼效率，在LQG控制器中加入了阻尼补偿器(DC)。LQG-DC控制器的目的是恢复电网隔离电力系统因负载突然变化而产生的标称电压。采用传统的比例积分导数(PID)、线性二次调节器(LQR)和LQG控制器后，AVR系统的响应与LQG- dc控制方案进行了比较，证明了其有效性。

An Optimal LQG-DC Control for Compensating Voltage Fluctuation in a Single Area Power System

In this technical brief an optimal linear-quadratic-Gaussian (LQG) control scheme is proposed for the robust control of an automatic voltage regulator (AVR) in a single area power system. In order to improve the overshoot damping efficiency of the system a damping compensator (DC) is incorporated with the LQG controller. The aim of this LQG-DC controller is to restore the nominal voltage of a grid isolated power system due to sudden load variation. The response of AVR system after implementing conventional proportional-integral-derivative (PID), linear-quadratic-regulator (LQR) and LQG controller is compared with the proposed LQG-DC control scheme to prove its efficacy.
