Abstract

The invention discloses a control system of a wind-driven generator. The control system comprises a fixing bin, an environment temperature detector, an environment humidity detector, a heating device,a fan, an air delivery passage, a reflectivity detector and a controller. The air delivery passage is long-strip-shaped. The vertical side part of the air delivery passage is equipped with an air blowing opening. The upper part of the air blowing opening is located above a blade. The lower part of the air blowing opening is located below the blade. The reflectivity detector is used for detectingreflectivity of the middle part of the blade. The controller is used for controlling the fan and the heating device to work when environment temperature detected by the environment temperature detector goes down to or is below the reference temperature value and environment humidity detected by the environment humidity detector goes up to or is above the reference temperature value. The controlleris also used for controlling the fan and the heating device to continuously work when reflectivity detected by the reflectivity detector deviates from the reference reflectivity value. The control system detects environment temperature and humidity and determines the condition that the blade may get frozen. Through the air delivery passage, hot air is delivered for the blade, thereby preventing the blade from being frozen.

Description

technical field [0001] The present invention relates to electrical control systems. More specifically, the present invention relates to a control system for a wind power generator. Background technique [0002] Wind turbines are generally composed of components such as wind rotors, generators, steering devices, towers, speed limiting safety mechanisms, and energy storage devices. Its working principle is relatively simple. The wind wheel rotates under the action of wind force, which converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft, and the generator rotates to generate electricity under the drive of the wind wheel shaft. In a broad sense, wind energy is also solar energy, so it can also be said that a wind generator is a thermal energy utilization generator that uses the sun as a heat source and the atmosphere as a working medium. Therefore, wind power generators have no fuel problem, nor will they produce radiation and air polluti...
