WIND POWER PLANT WITH PARALLEL POWER STATIONS USING MULTIPLE ISOLATED GENERATOR DEVELOPMENTS

摘要

A system and method are provided to isolate outputs 340, 345, 350, 355 of parallel converter threads 20-1, 20-2, 20-3, 20-n of a converter 20 on a generator side of a wind turbine generator 14 by utilizing isolated power windings 310, 315, 320, 325 on the wind turbine generator 14. Such isolation eliminates the circulating common mode current between the parallel converter threads 20-1, 20-2, 20-3, 20-n of the converter 20 and eliminates the need for a common mode inductor. System reliability is enhanced and total system cost is reduced.
