Abstract

The invention relates to the technical field of motors, and concretely relates to a generator, a power generation system and a generator control method. The generator is provided with at least one phase of stator winding. Each phase of stator winding comprises: at least one stator coil group, wherein each stator coil group is provided with at least one stator coil; and a winding switching unit connected with the stator coil group. The winding switching unit is used for switching the wiring mode of the stator winding of the target generator based on the load current of the target generator. Byswitching the wiring mode of the stator winding based on the load current of the target generator, the target generator has high efficiency and output power under different load currents, the voltageregulation rate is reduced, the high-performance working interval of the target generator under different load conditions is expanded, any original structure of the target generator does not need to be changed, an independent motor unit does not need to be added, and the weight and size are not increased.

Description

technical field [0001] The present invention relates to the technical field of electric machines, in particular to a generator, a power generation system and a generator control method. Background technique [0002] There are various forms of ocean energy in the ocean, such as current energy, wave energy, tidal energy, etc. It is of great significance to convert these energy into electrical energy. The ocean energy power generation system converts the energy into kinetic energy of rotation or linear reciprocating motion through energy capture devices such as impellers and floats, and then converts the kinetic energy into electrical energy through a generator. As the core component of the secondary energy conversion unit of the marine energy power generation system, the output power of the generator is the output power of the system, so its output characteristics directly affect the entire system. [0003] Compared with asynchronous generators, although permanent magnet gene...
