Abstract

Low frequency oscillation (LFO) is harmful to power system security and stability. The traditional solutions for LFO are the power system stabilizer (PSS) with local or global signal implemented on the excitations. This paper explores the global governor-side damping controllers for LFO, i.e., controller with input from the wide area measurement system (WAMS). Design strategy of global governor-side damping controller with remote signal from WAMS is proposed, based on the partial state feedback theory. Simulation results in a 4-generator-2-area power system show the effectiveness of the proposed global governor-side damping controller.
