Problems solved by technology
The synchronous generator is the basis of grid power generation. The speed of the prime mover must obey the natural frequency of the grid and cannot be changed with the requirements of the prime mover. In order to generate electricity, an inverter system needs to be added. Due to the complexity of the inverter system and the difficulty of technology, it will affect the performance of the system. Reliability, and increased investment, and high-order harmonics will be generated during operation, which will affect the quality of power supply

The invention discloses a birotor synchronous generator which comprises a stator winding coil, a permanent magnet rotor coil, a mouse cage rotor coil, a guide line shaft and a drive shaft, wherein the stator winding coil is fixed on the guide line shaft, the mouse cage rotor coil and the permanent magnet rotor coil are placed at the two sides of the stator winding coil and are fixed on the guide line shaft through bearings, and the mouse cage rotor coil is connected with a power machine through the drive shaft. The speed of the power machine of the generator can be changed in a certain range, and the generator has characteristics of the synchronous generator, therefore, no complicated inversion system is needed, and further, the synchronous generator can simply, safely and reliably operate like an asynchronous generator.
Description
technical field [0001] The invention relates to a generator, in particular to an induction type permanent magnet synchronous generator. Background technique [0002] Traditional generators are divided into asynchronous and synchronous generators, the main components of which include stators and rotors. Whether it is a synchronous generator or an asynchronous generator, each has its own advantages and disadvantages, and is suitable for different prime movers. [0003] The asynchronous generator is simple, safe, and easy to maintain. It can be directly connected to the grid for power generation, and the speed of the prime mover is variable. However, the asynchronous generator needs to absorb reactive power from the grid, and has other disadvantages such as low power factor. The synchronous generator is the basis of grid power generation. The speed of the prime mover must obey the natural frequency of the grid and cannot be changed with the requirements of the prime mover. In ...
