METHOD FOR GENERATING AN ALTERNATING CURRENT BY MEANS OF AN INVERTER OF A WIND TURBINE
Provided is a method for generating a multiphase electrical alternating current having a sinusoidal fundamental wave in each phase by a multiphase inverter of a wind power installation. The multiphase inverter is controlled by a tolerance band method which respectively has an upper and a lower band...

| description | Provided is a method for generating a multiphase electrical alternating current having a sinusoidal fundamental wave in each phase by a multiphase inverter of a wind power installation. The multiphase inverter is controlled by a tolerance band method which respectively has an upper and a lower band limit for each of the phases of the inverter. The inverter has, for each phase, an upper switch for generating a positive sine half-wave of the alternating current of the phase and a lower switch for generating a negative sine half-wave of the alternating current of the phase. The method includes generating the positive sine half-wave by the upper switch and generating the negative sine half-wave by the lower switch based on the band limits of the phase, and changing at least one of the band limits such that a signal component superimposed on the respective sinusoidal fundamental wave is reduced. |
