  • Generator-fault-tolerant control for a variable-speed variable-pitch wind turbine
    Patent number: 8928165
    Abstract: A fault-tolerant control system and method for variable-speed variable-pitch wind turbines with an inverter-fed generator. When generator faults are detected, the generator torque and/or flux is limited to prevent propagation of the faults and possible failure and shutdown of the generator. The control system and method improves on two-loop control methods for variable-speed variable-pitch wind turbines and provides improved power delivery under fault conditions.
    Type: Grant
