[0003] The asynchronous generator is simple, reliable, 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, which affects its power factor, and the efficiency of the engine is relatively low.
Synchronous generator is the basis of grid power generation. The efficiency of generator is relatively high, but synchronous power generation requires the speed of generator to adapt to the frequency of the grid. The speed of the prime mover must be fixed and cannot be changed with the requirements of the prime mover. For power generation, an electronic inverter system needs to be added. Due to the complexity and technical difficulty of the inverter system, the reliability of the system is affected, and the investment is increased. High-order harmonics are also generated during operation, which affects the quality of power supply.

The invention discloses a horizontal double-rotor generator. The generator is sequentially provided with a winding stator, an inner rotor, an outer rotor and a rotating shaft from outside to inside, and the winding stator is fixed on the rotating shaft through bearings on the front and rear end covers. Above, the outer rotor is fixedly connected to the rotating shaft and is driven to rotate by it, the inner rotor is fixed on the rotating shaft through bearings at both ends, and the rotating shaft is connected to the power machine. The horizontal generator can operate asynchronously and synchronously to generate electricity. The speed of the prime mover of the generator can be changed within a certain range, and it has the characteristics of a synchronous generator. It does not need to invest in a complicated inverter system. It is as simple, safe and efficient as an asynchronous generator. reliable operation.
Description
technical field [0001] The invention relates to a generator, in particular to a power generation device capable of asynchronous operation and synchronous power generation. 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, reliable, 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, which affects its power factor, and the efficiency of the engine is relatively low. Synchronous generator is the basis of grid power generation. The efficiency of generator is relatively high, but synchronous power gene...
