Ferroresonance, as an undesirable disturbance, leads to significant overvoltage and distorted waveforms.This phenomenon can be highly damaging to voltage transformers and other parallel-connected equipment and can entail catastrophic consequences.This paper aims to 27" Warming Drawer design and study a solid-state ferroresonance-suppressing circuit (SSFSC) to protect voltage transformers (VTs) together with other parallel-connected equipment in wind generation systems from the adverse effects of the ferroresonance phenomenon.The proposed structure consists of low-voltage circuits, including power IGBTs.The excellent performance of the proposed SSFSC in suppressing ferroresonance overvoltage in wind generation VTs has been authenticated by analyses conducted utilizing a wind generation system model.

In order to validate the performance of the proposed SSFSC, detailed analytical studies and time-domain simulations have been carried Pre-Workout out employing a MATLAB/Simulink environment.The results verify that the proposed SSFSC can effectively suppress ferroresonance phenomena in VTs and mitigate their accompanying overvoltages with a high operational speed.
