Combined with shortcomings existing monitoring system for ice coating and models to monitor ice coating, weight method based on static mechanics should be optimized and a dynamic model should be considered; big data should be used to improve the function of warning of monitoring system and advanced functions of system are needed. KEY WORDS：monitoring system for ice coating，calculation model, weighting method, dynamic model, big data 摘要：介绍了输电线路覆冰在线监测系统的结构和功能，综述了国内外覆冰在线监测模型方法，并比较其优缺点。结合现有覆冰在线监测系统与监测模型的不足，提出要优化基于静态力学的称重法，加入动态模型；要综合大数据应用，提高系统预警，开展系统高级应用功能。 关键词：覆冰监测系统，监测模型，称重法，动态模型，大数据 1 引言 输电线路覆冰问题一直是影响中国电力系统安全稳定运行的重点和难点问题，其他国家也存在同样的问题。输电线路覆冰和积雪会导致其机械和电气性能急剧下降，造成导线断线、金具损坏、杆塔倾斜、绝缘子冰闪、线路跳闸，严重甚至引起电力通信中断事故 ADDIN EN.CITE  ADDIN EN.CITE.DATA [1-3]。2008年初，我国南方地区遭受了严重的冰雪灾害，国家电网、南方电网的直接经济损失分别达104.5、150亿元 ADDIN EN.CITE EndNoteCiteAuthor李庆峰/AuthorYear2008/YearRecNum84/RecNumDisplayTextstyle face=superscript[4]/style/DisplayTextrecordrec-number84/rec-numberforeign-keyskey app=EN db-id=5tdrew9af55ep6e2x94pfafted2strfeata5 timestamp=144835000284/key/foreign-keysref-type name=Journal Article17/ref-typecontributorsauthorsauthor李庆峰/authorauthor范峥/authorauthor吴穹/authorauthor高剑/authorauthor宿志一/authorauthor周文俊/author/authors/contributorstitlestitle全国输电线路覆冰情况调研及事故分析/titlesecondary-title电网技术/secondary-title/titlesperiodicalfull-title电网技术/full-title/periodicalpages33-36/pagesvolume32/volumenumber9/number
