Permanent magnet speed regulation control method of wind driven generator

The invention relates to the technical field of wind power generation, in particular to a permanent magnet speed regulation control method of a wind driven generator. The permanent magnet speed regulation control method of the wind driven generator is characterized in that a permanent magnet speed regulation driving device is applied to a power transmission system of the wind driven generator, when the generator starts, operates normally, halts and operates abnormally respectively, the generator is controlled according to the rotating speed of a wind wheel, and accordingly the generator is kept in the optimal safe generating efficiency state. Compared with the prior art, the permanent magnet speed regulation control method of the wind driven generator has the advantages that the permanent magnet speed regulation driving device is creatively applied to the power transmission system of the wind driven generator, and the blank of applying the permanent magnet speed regulation driving device to the wind driven generator is filled; the generator can be flexibly started through the permanent magnet speed regulation driving device, and the power obtaining efficiency of the generator is improved; abrasion and vibration can be lightened to the maximum degree, and the service life of the generator and the service life of a gear speed changing box are prolonged; it is guaranteed that the wind driven generator can be kept to operate efficiently and safely within a wider wind speed range.
