摘要:
由于输电线路地处旷野,落雷频繁,雷电波沿线路侵入变电站从而损坏站内电气设备的事故频发。本文以某变电站的雷击事故为例,使用ATP-EMTP电磁暂态软件建立包含进线段和变电站的整体模型,仿真计算出主变及其它电气设备的雷电过电压及波形,分析该站遭受雷击事故的主要原因,并研究雷击点、杆塔接地电阻对站内设备过电压的影响,最后提出相应的防护措施。结果表明,事故的发生与雷电流侵入波的幅值过大、避雷器的安装位置距变压器较远有关,在变压器前加装避雷器方可有效避免此类事故。
Abstract:
As the transmission lines are located in the wilderness where the thunder is continual, lightning waves intrude into substations along the lines, causing frequent damage to the electrical equipment inside the station. In this paper, taking the lightning accident of a substation as an example, the ATP-EMTP electromagnetic transient software builds the whole model containing the line section and the substation. Then it calculates the lightning overvoltage and waveform of the main transformer and other electrical equipment. We analyze the main causes of the lightning accident and study how the lightning strike point and the grounding resistance of the pole and tower influence the station. Finally, we propose some corresponding protective measures. The results show that the accidents are related to the overshot of lightning current invading wave and the long distance between lightning arrester and transformer, and installing lightning arrester in front of the transformer can effectively avoid such accidents
