基于ATP-EMTP的全复合材料电杆线路防雷技术研究

复合材料电杆作为一种新型的输电线路电杆，因其具有绝缘性能强、耐腐蚀性好和质量轻等优点，应用于我国配电网线路可以有效提高线路绝缘性能，降低雷击跳闸率，提升线路整体技术经济性。以6 kV复合材料电杆的耐雷性能为研究对象，基于ATP-EMTP仿真分析平台，深入分析了复合材料电杆塔头的结构参数与分段接地方式对线路耐雷性能的影响，提出了较优的塔头结构和防雷接地方案。以某工程线路为例，塔头尺寸较优化前减小40%，优化后的接地方法较全线逐塔接地减少安装3/5的接地引下线，同时满足防雷考核指标，技术和经济性均有较大的提升。

Lightning Protection Technology of All-composite Pole Line Based on ATP-EMTP

As a new type of transmission line pole， the composite pole has the advantages of strong insulation properties，good corrosion resistance and light weight, thereby improving the insulation performance of the line， reducing the lightning trip-out rate， and enhancing the techno-economic performance of the line. Taking the lightning protection performance of 6 kV composite pole as the research object， the influence of the structural parameters for composite pole tower head and the sectioned grounding method on the lightning protection performance of the line is analyzed based on ATP-EMTP, and an optimized tower structure and a lightning protection grounding scheme are put forward. Compared with the line of a project， the size of the tower head is reduced by 40% after optimization，and the number of down-lead line to ground is reduced by 3/5, meeting the lightning protection assessment indicators，and improving the technology and economy significantly.
