FACTS & Fuzzy Logic based Controllers for Power System Stability.

      Аннотация: A coordinated Wide Area Damping Controller (WADC) based on the shunt connected FACTS based controllers and simultaneous tuning of FACTS based controller (specifically STATCOM and SVC)and fuzzy logic based global Power System Stabilizer (PSS) has been incorporated. A lead-lag based POD has been designed in the case of power system using STATCOM based Wide Area Damping Controller. The fuzzy logic based global PSS implemented for each area in two area four machine system is employing a global signal from power system as input to the stabilizer. The first input to the fuzzy logic controller incorporated in this book is speed deviation of respective generator and the second input is extracted from the active power transfer across the tie-line connecting both coherent areas. The output of fuzzy logic based global PSS provides the global stabilizing voltage signal for generator through its excitation system.
