Wind generating set network access method and system

The invention provides a wind generating set network access method and system. The system is composed of a power grid access module and a generating set module. The generating set module comprises a plurality of fans. Each fan comprises fan blades, a generator and a control system. Low-frequency output is adopted in the generators. The generating set module further comprises first converters which are connected to the output ends of the generators. The power grid access module comprises a transformer which is connected to the input end of the power grid access module. The first converters are used for converting low-frequency electric energy output by the generators into non-power-frequency electric energy and transmitting the non-power-frequency electric energy to a local transformer substation in a unified mode. The transformer is used for boosting electric energy and has accesses to a power grid. By the adoption of the wind generating set network access method and system, the weight, the size, the installi
