doi:10.11930/j.issn.1004-9649.201909001

Abstract

Abstract: In order to suppress the low frequency oscillation caused by governors, this paper proposes a new design method for the governor power system stabilizer (GPSS), where the requirement of the regulating speed is satisfied. A new GPSS optimization model was developed in the paper. The objective is to maximize the weighted summation of damping ratio margin and the time of the system to reach 90% load as the objective function, and its constraints include speed and stabilization time of primary frequency modulation requirement and stability requirement. A particle swarm optimization (PSO) based algorithm was developed for the optimization model. Simulation results demonstrate the effectiveness and feasibility of the proposed method.

Key words: governor power system stabilizer, low frequency oscillation, primary frequency modulation, particle swarm optimization algorithm, optimization design
