System and method for minimizing energy loss due to yaw untwist of a wind turbine

A system for minimizing energy loss caused by yaw untwist of a nacelle of a wind turbine, the system comprising:

• a yaw drive mechanism for adjusting a position of the nacelle;
• at least one sensor configured to monitor one or more wind conditions near the wind turbine;
• and
• a controller having one or more processors communicatively coupled to the at least one sensor, the controller configured to perform one or more operations, the one or more operations comprising:
• processing the one or more wind conditions for a given time interval, wherein processing the one or more wind conditions comprises:
• determining an average wind condition for the given time interval as a function of the one or more wind conditions;
• and
• determining whether the average wind condition for the given time interval is less than at least one of predetermined yaw untwist wind condition or minimum wind condition for the given time interval;
• receiving the position of the nacelle;
• and
• triggering a yaw untwist operation of the yaw drive mechanism when the position of the nacelle has rotated from an original position above a predetermined yaw threshold and the processed wind conditions are below a predetermined wind condition threshold.
