- Abstract:
- Based on the data of 247 earthquake disasters in mainland China from 1997 to 2017,we statistic the loss of power system in 97 earthquakes,and analyze the economic losses and its characteristic of the power system in earthquakes with different magnitude. The results show that:①The power system suffers an average of 4.6 earthquake disasters per year; ②The ratio of power system disasters caused by earthquakes increases with the increase of magnitude,and the disaster rates of M<5.0,5.0≤M<5.9,6.0≤M<6.9,M≥7.0 earthquakes are 13.6%,38.9%,56.2% and 62.5% respectively,and 38.5% on average. ③The economic losses of power system caused by earthquake increase with magnitude,but the relationship between them is nonlinear. ④Power system disasters caused by earthquakes mainly occurred in western provinces of China,such as Yunnan,Sichuan,Xinjiang,and Gansu.
