Impacts of Typhoon Meranti on Distribution Circuits of Xiamen

Abstract

The typhoon Meranti has been the strongest typhoon since the founding of the People's Republic of China, causing serious damage to the distribution circuits in Xiamen. By using geographical information system (GIS), the meteorological observation data were processed to obtain the distribution of wind and rain during “Meranti†period, and the distribution of disaster loss of distribution circuits was sorted out in Xiamen. Four typical disaster loss points were selected based on the specific types of disaster loss, and the causes of disaster were analyzed and studied. The results show that the distribution circuits of Xiamen island are damaged due to the problems in the design and operation of distribution circuits in the uncabled area with gentle topography. The terrain outside of Xiamen island is relatively harsh, and there are also problems of heavy wind and rain, distribution circuits design and operation and maintenance resulting in the damage of wiring.
