Fault-Tolerant Wind Energy Conversion System

March 25, 2020


Enables widespread adoption of wind energy by improving reliability

Technology Overview

To improve the reliability of power systems with large-scale wind power integration, different countries have specified fault ride through requirements for wind turbines in their respective grid codes. The fault tolerant system has been developed for a wind-based generation system using a doubly-fed induction generator (DFIG). The system is comprised of a DFIG wind turbine with a rotor and a stator coupled to an electrical grid, rotor-side converters, and a nine-switch convertor circuit.
