technical field

The utility model relates to a generator, in particular to a wind power generator which adds artificial intelligence and can control multiple sets of generators to share the operation.

Background technique

Wind power generators convert wind energy into mechanical energy through wind turbines or wind turbines, and then use generators to generate electricity. The efficiency of a wind turbine is affected by the wind speed, the design of the wind turbine blades and the wind area of the blades. The main structure of a wind turbine includes blades and a transmission mechanism. Wind energy can drive the blades to rotate and convert them into mechanical energy, and the transmission mechanism generates rotational torque and speed to drive the connected generator set to convert it into electrical energy.

The current design of wind turbines all regulates the rated power generation at the rated wind speed, and when the wind speed is greater than the predetermined range of the rated value, the wind turbine or wind turbine must be braked to stop the operation to avoid damage to the generator set due to excessive speed.
