Research on Seismic Performance and Emergency Response of Electric Power System

摘要

As a main part of lifeline networks, electric power system is apt to suffer cascading failures during a severe earthquake, which subsequently will partially or even fully paralyze a modern city. This has been widely proved by recent earthquake disasters. Therefore, this paper firstly reviews the malfunction and damage of electric power systems in 5.12 Wenchuan earthquake. Emphasis is put on the main failure characteristics of different power facilities under earthquake attack. Then, earthquake resistance design methods and some seismic equipment of electric power facilities are introduced. At last, emergency responses during earthquake and rapid restoration of service after earthquake for electric power system are systematically presented. It is shown that State Grid of China should immediately take thorough seismic research on power equipment to enhance the safety and power supplement capacity of electric system.
