Beschreibung
Zusammenfassung:	The invention relates to a method for controlling a wind power installation (100) and the wind power installation comprises a generator (101) for generating a generator current with one or more generator current phases, and an active rectifier for rectifying and controlling the generator current, wherein for each generator current phase the rectifier has a plurality of controllable sub-rectifiers (201-203), each controllable sub-rectifier (201-203) is characterized by a partial inductance (231-233), and each controllable sub-rectifier (201-203) controls a partial current of the generator current phase and each generator current phase forms a summation current as a sum of all the partial currents of the relevant generator current phase, wherein the active rectifier is controlled so that for each generator current phase the summation current is detected and each controllable sub-rectifier (201-203) of the relevant current phase controls the partial current thereof depending on the detected summation current.
