Abstract

Abstract:

On March 3, 2022, the failure of Xingda power plant managed by Taiwan Power Company resulted in a large-scale blackout in Taiwan, China, and the blackout lasted for 12 hours until load was restored. The accident affected about 5.49 million people, which had a great negative impact on the local people’s life, economic development and social stability. Firstly, this paper introduces the general situation of power grid in Taiwan, China. Then, the process of power outage is described, and the reasons of power outage are analyzed and combed in combination with the public report of Taiwan Province. Finally, by summarizing the power system problems reflected by the frequent accidents in Taiwan Province in recent years, some suggestions are proposed for the power grid development in the future.

Key words: large-scale blackout, Taiwan power grid, development of power grid
