摘　　要：为对华北500kV电网近3a来应用的在线监测系统进行深入分析探讨,将微气象、绝缘子污秽、应力及覆冰、导线金具及温度、微风振动等在线监测系统的应用及监测数据作为研究对象,对各在线监测系统的应用情况进行总结分析,指出系统应用过程中存在的理论模型、外部环境、能量供给、数据传输、价格成本等共性问题,给出了各在线监测技术手段的下一步发展方向,并分别针对各在线监测系统的继续深化应用给出建议。In order to analyze and discuss the application of on-line monitoring system in 500 kV power grid in North China in recent three years, the application conditions for each on-line monitoring system, such as micro-weather, contamination of insulators, conductor icing and stress, conductor fittings, temperature and vibration, were summarized. The common problems about theoretical model, external environment, energy supply, data-transmission, price and cost were pointed out. Some suggestions were given about deepening application for each on- line monitoring system.
