Abstract
Control systems are described that mitigate the effects of icing events on wind turbines. Example methods include determining, with a control system, that an icing event has begun to affect the wind turbine; based on a determination that the icing event has begun to affect the wind turbine, changing a phase of the wind turbine with the control system to an operational-icing phase by modifying angles of attack of blades of the wind turbine via changing blade pitch angles, wherein the wind turbine continues to generate electrical power when the wind turbine is in the operational-icing phase; and based on a determination that electrical power generation of the wind turbine is below a threshold, changing the phase of the wind turbine with the control system to a stopped-icing phase, wherein rotation of the blades of the wind turbine is halted when the wind turbine is in the stopped-icing phase.
