Problems solved by technology

These methods for detecting the icing conditions of wind turbines or blades may misjudge that the blades are not icing because the blades are not icing, or misjudge that the blades are not icing because the blades have been icing but have not reached a serious level. The reliability of the test results is poor
Moreover, the above-mentioned deicing device melts the ice layer by heating the blades. Since the blades are mostly made of cloth or fiber materials, the properties may change when the temperature rises and affect the service life of the blades. In severe cases, it may be caused by excessive temperature. Spontaneous combustion of blades, etc., affect the working safety performance of the fan

Abstract

The invention discloses a blade deicing system of a wind generating set. The blade deicing system comprises an image detection element (1), a control element (2) and an deicing element (3); the image detection element (1) is used for detecting the icing condition of a blade (4) of the wind generating set in real time and converting the icing condition into an image signal; the control element (2) is used for receiving the image signal and controlling the action of the deicing element (3) according to the image signal and a predetermined image signal; and the deicing element (3) is used for clearing an ice layer on the blade (4) under the control of the control element (2). High precision degree of the image signal ensures timely discovery of the icing problem; and the data of the icing condition can be directly acquired from the image signal, so the error is small and the timely discovery of the icing problem is further ensured.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a blade deicing system for a wind power generating set. The invention also relates to a wind turbine comprising the above-mentioned blade deicing system. Background technique [0002] With the outbreak of energy crisis worldwide, wind power and other renewable energy sources have been more and more widely used, thus driving the development of wind power generation systems. [0003] Wind power generation is a power generation method that converts the kinetic energy of wind into electrical energy. The device required for wind power generation is called a wind turbine (hereinafter referred to as a fan), and the fan generally includes three parts: a wind wheel, a generator and a tower. The working environment of the fan is outdoors where wind resources are relatively abundant. When the air temperature is low or in rainy and snowy weather, ice may form on the blades. I...
