Comparison of Two Power System Stabilizers for the Power System Stability

In this study, the structure of an adaptive networks based fuzzy controlled power system stabilizer, conventional power system stabilizer and dual input stabilizer is presented. With constraints on data availability and for study of power system stability, it is adequate to model the synchronous generator with field circuit and excitation system, connected to a infinite bus. Then power system stabilizers are designed and applied on the single machine infinite bus system. A systematic approach for optimizing the parameters of the dual input power system stabilizer (PSS3B and PSS4B) using ISE technique has been presented and there dynamic response are checked on wide variation in loading condition. A comparative study is also done in between all power system stabilizers.
