摘要
稳定、可靠的电源供给是高压输电系统在线监测设备有效运行的关键。本文主要从能量收集与存储方面综述了输电线在线监控终端的电源供给技术现状,重点评述了被测系统内部取电、外部取电及多种方式组合取电,以及基于电池和超级电容器储能技术在高压输电系统在线监测方面的应用,并梳理了这些技术方案的优势以及亟待解决的问题。在此基础上,进一步探讨了在线监测系统供电方式的前景及未来的发展趋势。
Reliable and stable power supply is a key to an effective operation of on-line monitoring equipment of a high voltage(HV)transmission system.This paper reviews power supply technologies commonly used for on-line monitoring terminal of transmission lines with a focus on energy collection and storage.Energy collection technologies include mainly the taking of electricity from the measured system,the taking of electricity from the outside of the measured system,and combining electricity using multiple ways.The energy storage technologies include electrochemical based battery technologies and supercapacitor based storage technologies.The advantages of these technologies and the problems that remain to be resolved are summarized.Based on the above,we discussed future development trends of power supply modes of on-line monitoring systems.
