摘要
无线公网通信是当前配电自动化主流的通信方式之一,配电终端配套安装无线通信模块后可以和配电网主站系统进行数据交互。公网通信依托于运营商网络,容易出现网络状况不佳的情况,而且模块长期在户外运行,周围存在各类电磁干扰,模块和SIM卡存在一定的故障率,导致通信异常。通过将无线通信的状态特性与配电物联网技术相结合,提出了一种切实可行的状态监测及评估方法,实现对配电网无线通信实时状态的监控、异常的准确定位和运行状况的分析,能有效提升配电自动化无线公网通信的可用性。
Public wireless network communication is one of the mainstream communication media in power distribution automation.The distribution terminal can interact with the main station system of the distribution network after installing the wireless communication module.The public network communication relies on the network operators,which is prone to poor network conditions.Moreover,the reliability can be affected by facts that the module runs outdoors for a long time where various electromagnetic interference exists as well as that the communication module and SIM card have a certain failure rate.By combining the characteristics of wireless communication with the technology of distribution Internet of Things,a feasible state monitoring and evaluation method is proposed to realize the monitoring of the real-time state of wireless communication of distribution network,the accurate positioning of abnormalities and the analysis of the running status,which can effectively improve the availability of wireless public network communication of distribution automation.
