Voltage Stability Improvement of Standalone SEIG Based Wind Plant Using Fuzzy Logic Controlled SVC

Self Excited Induction Generator (SEIG) is a major part of stand-alone wind vitality frameworks, are well known in later times among farther ranges. This situation occurs because these types of generators increasingly depend on much external intervention for reactive power control in isolated systems. This article focuses to analyse arranged applications of a static VAR compensator (SVC) for voltage control headway in division list SEIG based wind control systems. The standalone wind power plant has been developed along with the SEIG and fuzzy logic-based control of SVC. The simulations have been carried out without SVC, with open loop control of SVC, closed loop control of SVC and finally with Fuzzy based control of SVC. The developed standalone system simulations have been carried out for all resistive and inductive load scenarios with a constant power factor and obtain the data to sketch the power voltage (pv) curves of the system. The pv curves have been drawn for both resistive and inductive loads in all cases viz. open loop control, closed loop control as well as fuzzy logic-based control of SVC. The analysis on voltage stability of standalone wind plant has been done with all cases with both R and RL loads.
