FBG传感技术在云南山地高压变电站及输变电设备在线监测中的应用研究
Application of FBG Sensor Technology to On-line Monitoring of Montanic High Voltage Substations and Power Transmission/transformation Equipment in Yunnan Province
摘要
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.关键词
