WIND POWER PLANT HARMONIC SUPPRESSION METHOD, WIND POWER GENERATOR SETS, AND WIND POWER STATION

摘要

In a wind power plant harmonic suppression method, grid-connection of a wind power generator sets is achieved by using transformers with different phase-shifting angles on a same feeder line, harmonic waves produced by nonlinear currents are counteracted due to the fact that the phase-shifting angles of the transformers are different, and therefore harmonic output on a power grid of a wind power plant is reduced. The wind power generator sets comprise a wind turbine, a power generation system, and a phase-shifting transformer used for connecting the grid. The wind power station comprises at least two wind power generator sets being spatially adjacent and having a same model.
