Assignee: REGENTS OF THE UNIVERSITY OF MINNESOTA
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 9:
10. A wind turbine control system comprising:
a communication unit configured to communicate with one or more controllers of a wind turbine; and
one or more processors configured to:
determine 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, change a phase of the wind turbine with the control system to an operational-icing phase, wherein changing the phase of the wind turbine to the operational icing phase comprises:
determining a modified angle of attack of blades of the wind turbine based on a current wind speed, current power production of the wind turbine, and baseline power production data; and
modifying an angle of attack of the blades of the wind turbine to the modified angle of attack 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, change 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.
