电力系统地震灾害预防技术综述

An Overview on Prevention Technology of Earthquake Disaster for Power Grids

唐山地震之后,电力系统地震预防研究取得了极大进展,但由于地震预防的复杂性,目前还没有电力系统灾害预防研究的成熟成果。文中分析了电力系统地震预防的基本原则和方法,比较了最近几次亚洲大地震(唐山、阪神和汶川)对电力系统的破坏情况,总结了地震预防经验,最后讨论了如何在电力系统工程中实施地震预防。

Since the earthquake occurred in Tangshan, China in 1976, the research on earthquake disaster prevention for power grids obtains obvious progress, however due to the complexity of earthquake prevention, at present there is not yet mature research results in this field. Basic principle and methods to prevent earthquake damage in power system are analyzed and the damage of power grids due to the earthquakes occurred in Tangshan and Wenchuan in China as well as that due to the earthquake occurred in Osaka-Kobe in Japan are compared, then the experiences to prevent earthquake damage are summarized. Finally, how to implement earthquake prevention in power system projects is discussed.
