随着国家电网提出建设坚强智能电网计划的加速,电力行业的管理对数据的采集和传输手段要求越来越高,原有的抄表模式已经不能满足需求。近年来,低压电力线载波抄表占据了主流地位,在大规模现场应用方面取得了一些成绩。但是这种方式存在以下局限性:低压配电网环境复杂,干扰大;多台变供电时,存在载波串扰现象;载波传输距离有限,不适合农村、城乡结合部等低密度住宅;通信实时性差,无法满足远程费控要求。
With the State Grid proposed to build a strong smart grid plan to speed up the management of the power industry on the data collection and transmission means higher and higher, the original meter reading mode can no longer meet the demand. In recent years, low voltage power line carrier meter reading occupies the mainstream status, made some achievements in large-scale field applications. However, this approach has the following limitations: Low-voltage distribution network environment is complex and interference is large; carrier crosstalk occurs when multiple power supplies are supplied; carrier transmission distance is limited and is not suitable for low-density residential buildings such as rural areas and urban-rural integration; poor real-time communication , Unable to meet the remote charge control requirements.
