Fault Handling System for Doubly Fed Induction Generator

March 25, 2020


Improves fault handling in grid-connected systems

Technology Overview

The system is a fault ride through (FRT) transient management system configured to enhance the FRT capability of doubly-fed induction generator (DFIG)-based wind turbines. The system is comprised of a DFIG wind turbine, rotor-side converters, grid side converters, power electronic switches for system reconfiguration, a series braking resistor, a shunt braking resistor, a low-pass LC filter, and a series transformer.
