摘　　要：为了保障特高压换流站的安全稳定运营,经常需要对电力设施稳定性进行监测,传统监测方法 (如水准测量、GPS等)监测范围小、监测周期长、监测精度低、受外界环境影响大。本文提出了一种利用高分辨率TerraSAR-X数据对某特高压换流站开展站区和边坡的稳定性监测的新方法,采用SBAS-InSAR技术从小量数据集中解算出该换流站的形变和高程的算法,并分析了该换流站的稳定性,取得很好效果。In order to guarantee the safety and stability of the operation of UHV convertor station, a constant monitoring over the stability of electrical power facility is required, while traditional monitoring methods （such as leveling and GPS） have shortcomings like small monitoring scope, long monitoring period, low monitoring accuracy and can be largely affected by the external envirom＇nent.This paper introduces a method and process of stability monitoring of slopes and ultra-high voltage convertor stations using high resolution TerraSAR-X data. An algorithm has been put tbrward that the deformation and elevation of the convertor station can be calculated out of small data sets by applying SBAS-InSAR technology. And the stability of the convertor station has been analyzed.
