Abstract

This study presents the implementation of a system that used conversion of wind energy that integrated a doubly fed induction generator (DFIG) and static compensator (STATCOM) when exposed to various faults. The analysis focuses on critical aspects like DC-link capacitor voltage, rotor speed, and torque using electromagnetism, and AC-side voltage and current at HVDC terminal buses. WECS was connected to an HVDC line via a voltage source converter (VSC), with a fault occurring in the vicinity of the wind generator network. The endurance of DFIG was enhanced by STATCOM through the involved control method. This strategy effectively mitigated oscillations in both the supplies for voltage and torque, resulting in improved power flow. The study also investigated the impact of STATCOM on faults and the stability of the system considered. By implementing the proposed control method, it alleviates the adverse side of grid faults on windenergy conversion systems. The observation describes the potential of the STATCOM to strengthen the total performance and reliability of the considered system under fault situations.
