Abstract

This paper presents the first individual channel analysis and design (ICAD) of a high-order synchronous generator and a static VAr compensator (SVC) featuring a damping control loop. Particular emphasis is given to the closed-loop performance and robustness assessments. Fundamental analyses are carried out using ICAD and its frequency-domain approach to explain the dynamic behavior of the generator affected by an SVC with damping capabilities. A coordinated SVC voltage and damping control is achieved in a straightforward fashion owing to the transparent manner in which ICAD treats the complex interactions taking place between the synchronous generator and the SVC with a damping control loop. Using the ICAD framework, an indepth comparison is made between the competing abilities to provide system damping of the SVC and the power system stabilizer.
