Embodiment 3
[0080] The difference between the third embodiment and the first embodiment, and the fourth embodiment and the second embodiment is that a third frequency conversion device 8 is arranged between the stator winding of the first motor and the power grid 5, so that the three-phase output from the stator winding end of the first motor 1 is The frequency of the alternating current may not be equal to the frequency of the grid, and the frequency is converted by the third frequency conversion device 8 before being input to the grid.
[0081] The reason why the third frequency conversion device 8 is added is that when the stator winding of the first motor 1 outputs three-phase alternating current at the grid frequency (for example, 50Hz is used in my country), if the number of poles of the first motor 1 is small, the rotor of the first motor 1 needs to be The motor 6 provides a relatively high rotational speed, while in water conservancy power generation and wind power generation, the p...
