Abstract

The invention discloses a control method of a wind power generator. According to the control method disclosed by the invention, a wind indicator and an angle sensor are matched with a PLC (Programmable Logic Controller) and a direction adjusting motor to realize automatic wind catch of the wind power generator; and a wind speed sensor, a rotating speed sensor and a temperature sensor are matched with the PLC and the direction adjusting motor to realize automatic over wind speed, over rotating speed and over temperature protection of the wind power generator. The control method disclosed by the invention can realize an initiative and automatic wind catch function of the wind power generator and an automatic protection function of the wind power generator at the condition with over wind speed, over rotating speed and over temperature, and thus the stability and safety of the wind power generator in work are greatly improved.

Description

technical field [0001] The invention relates to the field of control methods, in particular to a control method for a wind power generator. Background technique [0002] A wind generator is a device that uses wind energy to generate electricity. It consists of a machine head, a generator installed in the machine head, a movable rotator for the machine head, a steering motor that drives the rotator to move, and a It is composed of the blade on the blade and the empennage installed on the blade, etc., wherein the central shaft of the blade is connected with the generator rotor by transmission. The blades drive the machine head to rotate under the action of wind, so that the rotor in the generator rotates to generate electricity. In the prior art, the wind direction of the wind generator is unstable, the wind speed is too fast, the rotor speed of the wind generator is too fast, and the winding temperature of the wind generator is too high, which affects the normal and stable ...
