高压输电线路在线监测系统

Online Monitoring System of High Voltage Transmission Lines

随着全球大气环境的变化,极端的风雪天气在我国出现愈加频繁,架空输电线路绝缘子污闪、风偏闪络、导线舞动、覆冰等现象时有发生,往往会引起严重事故,严重地威胁我国架空输电线路的安全运行。在线监测技术作为智能电网的关键技术之一,是目前国家智能电网建设的重要研究方向。本论文首先介绍了我国的在线监测系统发展及应用状况,然后对在线监测产品的相关技术实现及指标做了介绍。在总结上述现状及技术实现的基础上,提出了对输电线路状态监测系统发展方向的看法并提出了相关建议。

With the change of global atmospheric environment, extreme weather becomes more frequent in our country. The overhead transmission line insulator pollution flashover, wind partial flashover conductor galloping, ice, and other phenomena occur from time to time to cause serious accidents, which threatens the safe operation of overhead transmission lines. Online monitoring technology is one of the key technologies of the smart grid. The paper first describes the development and application conditions of China＇s online monitoring system, and then introduces the technology of online monitoring products. Finally, it gives some suggestions on the development of the transmission line monitoring system.
