Abstract

The invention discloses an anti-icing and deicing system for a large wind power generation built-up blade. The system comprises a built-up blade body, wherein the built-up blade body is formed through that a fiber heating material layer is laid on an outer surface or a middle surface or an inner surface of a skin made of fiber base metal. A coating layer is laid on the outer surface of the skin to protect the fiber heating material and the skin fiber base metal. Two ends of the fiber heating material layer are respectively connected with a conductive electrode, and the conductive electrodes are connected with a fiber heating power supply through wires. The skin outer surface and the skin middle layer or the fiber heating material layer of the inner surface of the skin are all provided with temperature sensors, and outputs of the temperature sensors are connected with a temperature controller through signal wires. By the system, anti-icing and deicing of the large wind power generation built-up blade under the environment of low-temperature high-humidity and freezing can be achieved, and the problems that generating efficiency is reduced due to icing and electricity generation loss due to stopping are avoided. The anti-icing and deicing system for the large wind power generation built-up blade has important economic and social benefits.

Description

Technical field [0001] The invention relates to an anti-icing system for large wind power generation blades in a low temperature and high humidity icing environment, in particular to a large wind power generation combined blade anti-icing system. Background technique [0002] The shortage of traditional energy in the world has caused people to worry about the exhaustion of non-renewable energy. The development and utilization of wind energy as a renewable energy source has become a hot spot and inevitable development direction of the world. As an effective way to improve the utilization rate of wind energy and the efficiency of power generation, the single-unit capacity of wind turbines is continuously developing towards large-scale. In addition, in my country, the application of wind turbines is not only used in areas with more suitable climates, but also in areas with low temperature, high humidity and icing. [0003] In the low temperature and high humidity icing environment, t...
