摘要

提出了一种利用鲁棒线性二次高斯(LQG)控制器抑制电力系统区域间振荡的广域阻尼控制系统。所设计的鲁棒控制器能够处理不完全通信介质带来的通信噪声、测量噪声和信号延迟等问题。通过MATLAB/simulink中的非线性时域仿真验证了鲁棒控制器的性能,并在实时数字仿真器opal RT-lab上进行了软件在环(SIL)验证。

Real time simulation of a robust LQG based wide area damping controller in power system
This paper presents a wide area damping control system using robust linear quadratic Gaussian (LQG) controller for damping the inter area oscillations in the power systems. The designed robust controller is capable of dealing with the problem of imperfect communication medium, which introduces communication noise, measurement noise and signal latency. The performance of the robust controller is verified by the non-linear time domain simulation in MATLAB/simulink and Software-In-Loop(SIL) validation is performed on real time digital simulator opal RT-lab.
