Abstract

The invention discloses a motor rotation system capable of adjusting power generation efficiency. The system comprises a power supply, a starting capacitor, a motor, a speed regulation switch, a permanent magnet synchronous generator, a rectification module, an inversion module and a control system; the motor is electrically connected with the power supply through the speed regulation switch; the starting capacitor is connected with the motor in parallel; an output shaft of the motor is mechanically connected with the permanent magnet synchronous generator; the permanent magnet synchronous generator is electrically connected with the control system and the rectification module; the rectification module and the inversion module are electrically connected with the control system; the rectification module is electrically connected with the inversion module; the inversion module is connected with a power grid; the motor drives the permanent magnet synchronous generator to generate power; and the adjusting switch changes the power generation efficiency of a power generation system by adjusting the rotating speed of the motor. According to the motor rotation system capable of adjusting the power generation efficiency, the power generation efficiency can be further adjusted by adjusting the rotating speed of the motor according to the consumption of the power grid load, and supply and demand balance is basically achieved.

Description

Technical field [0001] The present invention relates to the field of power generation technology, and more particularly to a motor rotation system that adjusts power generation efficiency. Background technique [0002] Since the wind energy has certain kinetic energy, the existing wind power system is converted to mechanical energy through the wind turbine into mechanical energy and dragging the generator. The principle of wind power is to use the wind to drive the windmill blade rotation, and then the speed of the rotation will increase the speed of the generator through the speed. [0003] However, the existing wind power system has no way to increase or reduce the corresponding power generation according to the demand of the load consumption of the power grid, resulting in excessive power generation or excess of power generation. Inventive content [0004] To this end, the embodiment of the present invention provides a motor rotation system that adjusts power generation effic...
