Abstract

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.
