Wind Turbine Air Deflector System Control

摘要

One or more controllers may perform one or more methods to control one or more air deflector units of one or more wind turbine rotor blades. The methods include per-blade control methods that may be performed, e.g., to reduce blade loading caused by wind gusts. The methods also include collective control methods that may be performed, e.g., to reduce tower motion and/or rotor speed.

1. A method comprising:
receiving sensor data indicative of a current loading condition of a blade of a rotating wind turbine rotor, wherein
the blade includes a plurality of air deflector units having a current deployment configuration, andthe blade includes multiple sensors and the sensor data comprises a separate sensor value corresponding to each of the multiple sensors; obtaining a set of error values by subtracting a different one of multiple threshold scalar values from each of multiple different input values, each of the input values comprising a value based at least in part on a different one of the sensor values; summing values based at least in part on the set of error values to obtain a first summed value; generating actuator commands to at least one of the air deflector units to implement an updated deployment configuration of the air deflector units, wherein the updated deployment configuration corresponds to a data value based at least in part on the first summed value; and transmitting the actuator commands.
