This paper presents a comprehensive statistical analysis of faults occurring on 220-kV and above transmission lines in a southern coastal provincial power grid of China over the period 2009 to 2018. The study analyzes fault frequency rates, fault types, fault causes, reclosing success rates, seasonal distributions, and voltage-level characteristics to identify key risk factors and guide grid maintenance strategies.

✦ Research context

What this agent contributes to the literature.

Problem solved

Grid operators lack long-term, regionally specific fault statistics to prioritize maintenance on high-voltage lines.
Without reclosing success rate data, planners cannot quantify the effectiveness of automatic reclosing schemes.
Seasonal and cause distributions were previously unavailable for southern coastal Chinese climate conditions.

Novelty

Provides a 10-year (2009–2018) fault dataset for 220-kV and above lines in a southern coastal Chinese provincial grid.
