Power System Stabilizer scheduled by a fuzzy logic based supervisor from a local compensator network

Abstract:

This work presents a digital adaptive Power System Stabilizer (PSS) which operates in a gain scheduling scheme. Its parameters are designed for several differently selected operating points in a P×Q plane (active and reactive powers), and saved off-line under the form of a look-up table in the microcomputer that implements the control action. The complete set of all designed PSSs is called a Local Compensator Network (LCN). During working, the a fuzzy logic based supervisor identifies the current operating point, and synthesizes the PSS parameters from the LCN. The test presented shows good performance for this PSS, when compared to a conventional (non adaptive) one. © 2001 IEEE.
