Abstract

The present invention relates to a method and apparatus for controlling a wind turbine. The method includes: dividing a plurality of wind turbines into at least one group based on a similarity in status information of the plurality of wind turbines; in response to having detected a fault in a first wind turbine of the plurality of wind turbines, searching a group to which the first wind turbine belongs for a second wind turbine matching status information of the first wind turbine; and controlling the first wind turbine based on parameters from the second wind turbine.

First claim

1 . An apparatus, comprising:
a processor; and a memory storing instructions that, when executed by the processor, cause the apparatus to perform a method comprising:
receiving first status information regarding each of a plurality of wind turbines at a first time, the first status information for each of the plurality of wind turbines including status components, the status components including at least wind information and yaw information;
for each wind turbine of the plurality of wind turbines, determining a first difference between each status component of the first status information of that particular wind turbine and each status component of the first status information of every other wind turbine of the plurality of wind turbines;
for each wind turbine of the plurality of wind turbines, comparing the first differences between at least the wind information and the yaw information of that particular wind turbine and at least the wind information and the yaw information of every other wind turbine of the plurality of wind turbines to at least one status component threshold;
dividing the plurality of wind turbines into two or more groups based on the first differences and the first comparisons with the at least one status component threshold;
in response to one of a plurality of trigger conditions:
receiving second status information regarding each of the plurality of wind turbines at a second time, the second status information for each of the plurality of wind turbines including status components for each wind turbine of the plurality of wind turbines;
for each wind turbine of the plurality of wind turbines, determining a second difference between each status component of the second status information of that particular wind turbine and each status component of the second status information of every other wind turbine of the plurality of wind turbines;
for each wind turbine of the plurality of wind turbines, comparing the second differences between at least the wind information and the yaw information of that particular wind turbine and at least the wind information and the yaw information of every other wind turbine of the plurality of wind turbines to at least one status component threshold; and
re-dividing the plurality of wind turbines into two or more groups based on the second differences and the second comparison with the at least one status component threshold;

in response to having detected a fault in a first wind turbine of the plurality of wind turbines, identifying a group of the two or more groups to which the first wind turbine belongs and identifying a second wind turbine within the group of the two or more groups; and
controlling operation of the first wind turbine based on at least one parameter from the second wind turbine.
