- Abstract:
-
According to the China Electric Power Statistical Yearbook(2014-2021)and the data from the official websites of the electricity departments at all levels,a nationwide fundamental database of the transformer substations in Chinese mainland is established.The influence of the gas insulated substations and the variation of the substation's structure was involved in the damage assessment model.According to the proportion of the gas insulated substations in 5 regions in Chinese mainland,a model of the proportion of the nationwide gas insulated substations is established.Based on the simulated shaking table test of the high-voltage switchgear prototype structure of the gas insulated substation,and the results from the case study of the Wenchuan MS8.0 earthquake in 2008,an empirical vulnerability model of the gas insulated substation is given.Based on the proportions of the structure of the air insulated switchgear substations in 4 regions in Chinese mainland,the vulnerability model of the air insulated switchgear substations was updated,resulting in making a new assessment model of earthquake-caused losses.Finally,the earthquake-caused loss,the loss density and the loss ratio of the transformer substations subjected to the Intensity Ⅶ-Ⅹ earthquakes in the counties and districts in Chinese mainland are given.
