Beschreibung
Zusammenfassung:	The invention relates to a high protection level direct current grid-connected permanent magnet direct drive wind power system that comprises a wind wheel, a permanent magnet direct drive wind driven generator, a step up transformer, a rectifier, a direct current local area network, a high voltage inverter and master controllers. The permanent magnet direct drive wind driven generator is directly driven by the wind wheel in a coupling mode; the permanent magnet direct drive wind driven generator is connected with the step up transformer that is connected with the rectifier; and a high voltage direct current after rectification at an output end of the rectifier is electrically connected with the direct current local area network that is remotely connected with the high voltage inverter. Besides, the master controllers are respectively connected with the regulation and control wind wheel, the permanent magnet direct drive wind driven generator, the step up transformer, the rectifier, the direct current local ar
