Abstract :
This paper deals with the application of the LQG (linear quadratic Gaussian) technique to the design of a robust TCSC (thyristor controlled series compensator) controller for power system oscillation damping enhancement. This paper discusses each process involved in the LQG design technique applied to the TCSC damping controller design. This paper also discusses the pitfalls in applying the LTR (loop transfer recovery) technique to reserve the robustness of the LQG damping controller. The robustness of the designed controller is verified by nonlinear power system simulation, which shows that the controller is effective for damping power system oscillations
