基于无线加密通信的电缆在线监测系统设计与应用

随着电网建设的快速发展,高压电缆线路在城市电网的占比越来越大,同时电缆在线监测也得到了广泛的应用。但是目前存在的问题是电缆在线监测终端种类繁多、接口复杂、数据量大、布局分散,上级数据平台很难通过有线方式直接进行数据采集和接入,导致电缆局部放电、温度异常、绝缘降低等故障不能及时发现和处理而影响城市供电安全。针对在实际应用中遇到的问题和迫切需求,提出了一种基于无线专网的在线监测数据加密上送方案,分别从系统组成、网络架构、系统功能等方面来进行详细设计,并通过现场应用案例验证了方案的可行性及推广价值。

Cable Online Monitoring System Based on Wireless Encrypted Communication

With the rapid development of power grid construction,high-voltage cable lines account for an increasing proportion of urban power grids,and cable online monitoring has also been widely used.However,the current problems are that there are many types of cable online monitoring terminals,complex interfaces,large amounts of data,and scattered layout.It is difficult for the upper-level data platform to directly collect and access data through wired methods,resulting in cable partial discharge,abnormal temperature,and reduced insulation.Failures can not be discovered and dealt with in time,which affects the safety of urban power supply.In response to the problems and urgent needs encountered in practical applications,this paper proposes an online monitoring data encryption and uploading scheme based on wireless private network,which is designed in detail from the aspects of system composition,network architecture,and system functions.The field application case verifies the feasibility and promotion value of the scheme.
