A method of operating a wind turbine wherein the wind turbine includes a doubly-fed induction generator that converts rotational mechanical power to electrical power. The method includes operating the wind turbine in a first operational mode in which a speed of a rotor of the wind turbine is controlled to maximize the power generation by the wind turbine. Upon a monitored parameter reaching or dropping below a respective threshold, the wind turbine is operated in a second operational mode. The monitored parameter may include at least one of the rotational speed of the rotor, the rotational speed of the doubly-fed induction generator, a wind speed, an active electrical power, or generator torque. Operating the wind turbine in the second operational mode may include increasing the rotational speed of the doubly-fed induction generator at the expense of the generation of active electrical power by the power generating system.
A method of operating a wind turbine, wherein the wind turbine comprises a power generating system including a doubly-fed induction generator that converts rotational mechanical power to electrical power, wherein the method comprises:
A control system for controlling the operation of a wind turbine, wherein the control system is configured to be coupled to a power generating system of the wind turbine that includes a doubly-fed induction generator, the control system comprising:
