摘要：
This paper presents an approach. for designing fuzzy logic based adaptive power system stabilizers. In the initial design step, Prony analysis is used to identify linear models of a synchronous generator at a large number of operating points, consisting of various power outputs and machine terminal voltages. Next, optimal parameter settings for a conventional power system stabilizer (PSS) are generated using the linearized models. From the operating point settings, a selection of fuzzy rules are derived to tune the stabilizer on line according to real-time measurements. Simulation studies of this fuzzy adaptive PSS show that it performs well over a wide range of operating conditions and provides better dynamic performance than a fixed parameter conventional PSS.
