高山风电场升压站防雷接地降阻探讨

Discussion on Lightning Protection and Grounding Resistance Reduction of High Mountain Wind Electric Field Booster Station

随着风力发电等清洁能源的大力发展,以及大量先进的微电子电路配备于风电场升压站内,风电场升压站正面临着日趋严重的雷电灾害的威胁。为了确保升压站的防雷安全,提高风力发电的可靠性和持续性,迫切需要对升压站采取科学合理的防雷措施。本整改设计即是在现场环境的调查、气象资料的统计、规范要求的遵守的基础上,针对某高山风电场升压站的防雷接地降阻。主要根据实际情况进行综合设计,并应用土质相对应的防腐降阻材料,将升压站的接地电阻降至3.0欧姆以下,达到符合规范及设计要求。本文研究结果亦可为其他类似高山防雷接地降阻案例提供参考。

With the development of clean energy such as wind power generation, and a large number of advanced micro-electronic circuits installed in the wind farm booster station, the wind farm booster station is facing the threat of lightning disaster. In order to ensure the safety of lightning protection, improve the reliability and sustainability of wind power generation, it is urgent to take scientific and reasonable lightning protection measures. On the basis of the investigation of the scene environment, the statistics of meteorological data, and the observance of the standard requirements, we studied the lightning protection and grounding resistance reduction of a high mountain wind electric field booster station. According to the actual situation, we used the corresponding antiseptic and resistance material to reduce the grounding resistance of the booster station to less than 3 ohms, and has reached the specifications and design requirements. The results of this paper can also provide reference for other similar cases of lightning protection grounding resistance reduction in high mountains.
