Range-extending power generation system

The invention discloses a range extending power generation system which comprises a generator system, a starting generator, a starting controller, a special power supply and a system controller, and the output end of the system controller is electrically connected with the input end of the generator system and the input end of the special power supply through wires. And the output end of the generator system is electrically connected with the input end of the generator through a wire. According to the range-extending power generation system, the starting and generating integrated permanent magnet synchronous motor is adopted, the motor operates in a motor state in the starting process of the range-extending power generation system, the engine is started under the driving of the starting controller, the motor operates in a generator state after the engine is started, three-phase alternating current is output, a starter of a traditional range extender is omitted, and the weight can be reduced; the size is reduc
