摘要

随着碳纤维材料在海上风力发电机组长叶片中的广泛应用，碳纤维叶片的防雷技术成为亟待解决的问题。根据IEC61400-24要求，碳纤维叶片防雷需要在碳纤维材料表面布置导体防止碳纤维结构遭受破坏，目前碳纤维叶片防雷主要采用防雷金属网，但金属网需要在每次雷击后进行维护和修补，无形中增加了后期维护成本。结合接闪器和金属网的各自优势，提出了一种金属网结合接闪器的双回路防雷系统，并通过仿真分析验证了该系统的有效性。本防雷系统可减少叶片维护次数，提高风机安全可靠性，提升风电产品的市场竞争力。

Abstract

With the wide application of carbon fiber materials in long blades of offshore wind turbines, lightning protection technology of carbon fiber blades has become an urgent problem to be solved. According to IEC61400-24 requirements, lightning protection of carbon fiber blades requires laying conductors on the surface of carbon fiber materials to prevent damage to carbon fiber structures. At present, lightning protection of carbon fiber blades mainly uses lightning protection metal mesh, but the metal mesh needs to be maintained and repaired after each lightning stroke, which virtually increases the cost of maintenance. In this paper, a dual-circuit lightning protection system is proposed, which combines the advantages of air-termination and metal mesh. The effectiveness of the system is verified by simulation analysis. The lightning protection system can reduce the number of blade maintenance and improve safety and reliability of wind turbines then enhance the market competitiveness of wind power products.
