Abstract
A technique is provided for operating a wind farm at increased rated power output. The technique includes sensing a plurality of operating parameters of the wind turbine generator, assessing the plurality of operating parameters with respect to respective design ratings for the operating parameters, and intermittently increasing a rated power output of the wind turbine generator based upon the assessment.
Claims36
A method for regulating power rating of a wind turbine generator of a wind turbine, the method comprising:
- calculating a baseline predicted life of the wind turbine based on an estimated wind turbulence;
- sensing a plurality of operating parameters of the wind turbine generator;
- assessing the plurality of operating parameters with respect to respective design ratings for the operating parameters by estimating fatigue in real time based on wind history using signal processing via generated transfer functions of power and damage rates;
- uprating a power set point of the wind turbine when the assessment indicates that a sensed wind turbulence is lower than the estimated wind turbulence;
- and
- adjusting at least one boundary of at least one command signal to modify torque, speed, blade pitch, current, reactive power, or combinations thereof for dynamically modifying a rated power output of the wind turbine generator based at least in part upon the power set point.
A control system for regulating power rating of a wind turbine generator of a wind turbine, the control system comprising:
- a plurality of sensors for sensing a plurality of operating parameters of the wind turbine generator;
- a processor for calculating a baseline predicted life of the wind turbine based on an estimated wind turbulence, assessing the plurality of operating parameters with respect to respective design ratings for the operating parameters by estimating fatigue in real time based on wind history using signal processing via generated transfer functions of power and damage rates, uprating a power set point of the wind turbine when the assessment indicates that a sensed wind turbulence is lower than the estimated wind turbulence;
- and
- a controller for adjusting at least one boundary of at least one command signal to modify torque, speed, blade pitch, current, reactive power, or combinations thereof for dynamically modifying a rated power output of the wind turbine generator based at least in part upon the assessment power set point.
