Enhancing Resilience: Analysis and Prevention of Trip Caused by Bush Fire on Transmission Lines in North Eastern Regional Grid of India

The long last bush fire., causing the failure of transmission lines auto-reclosing., repeated trips or inability to restore the network quickly., poses a significant threat to the safety., reliability and stability of power systems. This paper analyzes the statistics of bushfire events affecting 132 kV and above transmission lines in the North Eastern Region (NER) of the Indian Power Grid from January 2016 to May 2024., examining the frequency of trips caused by bushfires and summarizing their characteristics and impacts. Besides., this paper also analyzes how bushfire causes transmission line trips with the help of live fault tracks and finds the paths through which transmission line discharge when trips happen and highlights critical preventive measures that led to a 35 % reduction in bushfire related tripping incidents. The strategies outlined in this paper offer valuable insights into mitigating the impact of bushfires on power transmission systems ensuring improved grid stability and reliability.
