Fault Analysis of Guangdong Power Grid in China During Typhoon Yagi (2024)

The escalating frequency of catastrophic typhoons presents a formidable challenge to power grid reliability. On September 6, 2024, Typhoon Yagi (2024) made a devastating landfall in Guangdong Province, China, causing numerous transmission lines to fail and severely damaging critical substation and distribution equipment, resulting in widespread power outages. Utilizing data collected during Typhoon Yagi (2024), this paper constructs a detailed profile of the storm’s meteorological characteristics. Subsequently, we conducted an in-depth analysis to identify the secondary disasters that typhoons may precipitate. Then, focus on assessing the extent of the damage to transmission, substation, and distribution infrastructure. Finally, we present strategic recommendations across three key areas: pre-disaster mitigation, during-disaster response, and post-disaster recovery. The ultimate goal of these strategies is to bolster the power grid’s resilience against the onslaught of typhoons and to curtail the impact of such calamities, offering a blueprint for bolstering our defensive measures against natural disasters.
