A passive filtering solution for overvoltage mitigation in doubly fed induction generator–based wind system fed by long power cable

, 2020
The inclusion of the latest generation of semiconductor switches in today’s wind farms allows high-frequency pulse width modulation. When the cable that connects the power inverter to the rotor of a doubly fed induction generator is long, the impedance ...

Discriminate Method of Power Frequency Ferroresonance in System with Non-Effectively Earthed Neutral of Three-Phase Enclosed GIS

China International Conference on Electricity Distribution, 2018
Ferroresonance overvoltage is one of the most important factors to impact electric equipment inner insulation. In system with non-effectively earthed neutral, the equipment damage caused by ferroresonance overvoltage possesses great proportion.
