- 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
