Embodiment Construction
[0028]After the generator is connected to the grid, power exchange occurs between the generator and the grid, generating stator current. The stator current has two functions. On the one hand, it provides enough torque between the stator winding and the rotor winding to maintain the The grid runs synchronously, converting the mechanical energy input from the shaft end of the generator into electrical output; on the one hand, it sends reactive power to the grid or absorbs reactive power, and forms the internal magnetic field of the generator together with the rotor current. There are two factors that affect the reactive power emitted by the generator. On the one hand, the excessive amplitude of the reactive power emitted by the generator will cause the stator current to increase. The stator current will cause the stator winding of the generator to heat up and the temperature will rise. The temperature of the stator winding determines the generator. The boundary between stator cur...
