Zusammenfassung:	Provided is a method for controlling a wind power installation. The wind power installation includes a generator for generating a generator current with one or more generator current phases, and an active rectifier for rectifying and controlling the generator current. For each generator current phase the rectifier has a plurality of controllable sub-rectifiers. Each controllable sub-rectifier is characterized by a partial inductance, each controllable sub-rectifier 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. The active rectifier is controlled so that for each generator current phase the summation current is detected and each controllable sub-rectifier of the relevant current phase controls the partial current thereof depending on the detected summation current.
