摘要

变电站在日常运行过程中，气体绝缘开关（GIS）设备若发生击穿故障，将会导致变电站电力供应暂停，国民生产和生活难以得到保障。文章针对GIS设备发生击穿故障后，如何快速有效地定位故障设备进行了探讨，提出将光纤分布式声传感系统（DAS）与机器学习方法中支持向量机（SVM）相结合，能够实现故障发生位置定位，利于故障的排除，利于运行风险的降低，同时对及时恢复变电站电力供应具有重要意义。

Abstract

During daily operation of Substation

if Gas Insulated Switchgear (GIS)equipment breaks down

it will lead to the suspension of substation power supply

and national production and life cannot be guaranteed. This paper discusses how to locate the breakdown of GIS efficiently and effectively. The Distributed Acoustic Sensing (DAS) system described in this paper is combined with Support Vector Machines (SVM) in machine learning method

which can realize fault location and facilitate fault elimination. At the same time

it is of great significance to restore the power supply of substation in time.
