摘要

云南地处高原

复杂的地质条件与气候环境使得大多数山地变电站普遍存在地质结构安全、电力铁塔变形和输变电设备隐蔽部位超温等安全隐患

严重威胁着电力系统的稳定运行。利用光纤Bragg光栅（FBG）传感技术电绝缘、抗干扰、高精度和使用寿命长等物理特性

面向山地变电站及输变电设备研发建立集传感与传输于一体的全光纤非电量传感网络及智能信息在线监测系统

及时准确掌握变电站地质结构、铁塔形变和输变电设备隐蔽部位运行温度的实时状态。该技术成功应用于云南电网公司昭通供电局220 kV盐津变电站。

Abstract

The geological condition and climatic condition are complicated in the plateau region of Yunnan Province

where potential safety hazards

such as the instable geological structure

the deformation of electric power transmission tower

and the overtemperature of the hidden parts of power transmission/ transformation equipment

exist in most montanic electric substations.This situation endangers safe operation of the electric power system.The non-electricity full optical fiber sensor network and the intelligent information online monitoring system

which can realize detection and signal transmission

was constructed based on the special physical properties of the fiber Bragg grating（FBG）

such as electric insulation

anti-interference

high precision and long service life

with consideration of the requirements of montanic transformer substation and transmission/transformation equipment.Consequently

accurate real-time monitoring of the geological structure

the power transmission tower deformation and the working temperature of the hidden parts of power transmission/transformation equipment were implemented.The FBG sensing technology has been applied successfully to the 220 kV Yanjin transformer substation of Zhaotong Power Supply Bureau of Yunnan Power Grid Corporation.
