Simulation and Experimental Study of Lightning Protection System of Carbon Fiber Spar Cap Wind Turbine Blade

  • 摘要: 用COMSOL Multiphysics数值仿真软件对一款碳纤维主梁叶片防雷系统雷电的附着点和雷电流损伤进行了仿真模拟, 并对具有该防雷系统的碳纤维叶片进行初始先导附着试验和电弧注入试验。仿真与测试表明, 雷电流主要在铜网上传播, 电流在折叠金属铜网上分布不均匀, 铜网较厚处的电流密度大于较薄处的电流密度, 距离注入点近的铜网的电流密度更大, 雷电电弧引入时, 铜网上会产生轻微熔蚀, 碳纤维大梁不会产生热损伤。试验数据与仿真结果吻合, 进一步验证仿真模拟的有效性和仿真结果的正确性。
    Abstract: COMSOL Multiphysics numerical simulation software was adopted to simulate the lightning attachment point and lightning current damage of a lightning protection system of carbon fiber cap spar blades. The initial pilot attachment test and arc injection test for the carbon fiber blades with lightning protection system were carried out. The simulation and test results show that lightning current mainly propagates via copper mesh, the current is distributed unevenly in the folded copper mesh. The current density in thick copper mesh is larger than that in thin copper mesh, and the current density near the injection point is larger. When lightning arc is introduced, slight corrosion will occur in copper network, and carbon fiber cap spar will not be damaged by the heat. The test results are coherent with the simulation results, which further verifies the validity and correctness of simulation.
