ADJUSTING RELATIVE ROTOR AZIMUTH POSITIONS TO REDUCE HARMONIC CONTENT IN POWER OUTPUT OF WIND POWER PLANT

摘要

A method and associated control system are disclosed for reducing harmonic content in a power output signal of a wind power plant, the wind power plant comprising a plurality of wind turbines including first and second wind turbines. The method comprises selecting a harmonic component from one or more harmonic components of the power output signal. The method further comprises adjusting, based on the selected harmonic component, a first rotor azimuth position corresponding to the first wind turbine relative to a second rotor azimuth position corresponding to the second wind turbine.
