Description

technical field [0001] The invention belongs to the field of wind power, and more specifically, the invention relates to an electric heating anti-icing and deicing system and a preparation method thereof. Background technique [0002] At present, energy transformation has become a basic national policy of our country. In 2015, the new installed capacity of domestic wind power reached 30.5GW, and in 2016, the total scale of national wind power development and construction was planned to reach 30.8GW. According to the baseline plan of the energy demand forecast of the Energy Bureau in 2020, the target of wind power installed capacity in 2020 is 210GW, with an average annual newly installed capacity of 42GW, and the average annual compound growth rate is 10.9%. A large number of wind turbines in my country are installed in cold regions and / or high-altitude regions, and the surface of wind turbine blades is often covered with ice, resulting in the failure of the performance of t...
