Design of a Fuzzy-Logic-Control Based Robust Power System Stabilizer

摘要

This paper presents a design procedure for a robust power system stabilizer(RPSS) based on fuzzy logic control techniques. Speed deviation of a synchronous generator and its derivative are chosen as the input signals of RPSS. A normalized sum-squared deviation(NSSD) index is used to design the RPSS and investigate the robustness of the RPSS for a multi-machine power system. Nonlinear simulation tests under different disturbances are given and their results are discussed.
