The invention provides an electric energy leading device and method of a wind generating set. The electric energy leading device including a leading cable, a leading cable fixing device, a wind generating set outgoing line, a wind generating set outgoing line fixing device, an annular conductor and the like is arranged between the wind generating set and a power grid, so that the wind generating set is driven by a fan impeller to generate electricity. The wind generating set outgoing line leads electric energy emitted by the wind generating set to the annular conductor, when a fan rotates along with wind, the annular conductor is always in close contact with the leading cable and the wind generating set outgoing line, and the electric energy is led out from the annular conductor by the leading cable. In the overall wind generating process, the electric energy emitted by the wind generating set can be transmitted to the power grid smoothly without shutdown adjustment.
