低压居民用户停电事件实时上报方法研究

本文提出了一种基于双模通信单元（微功率无线通信+窄带载波通信）实现低压居民用户停电事件实时上报的方法。通过对安装在智能电能表中的通信单元进行硬件电路改造、采集系统通信协议扩展及采集设备软件升级的方式，在故障停电时，通信单元立即生成智能电能表的停电事件并进行主动上报。本文同时提出一种防误报和防冲突的上报策略，使单户停电和台区停电均能得到高效上报，实现供电故障主动抢修，提升供电服务水平。

Research on real-time reporting method for power outages of Low-voltage residential users

This paper proposes a method for real-time reporting of low-voltage residential users'' power outage events based on dual-mode communication unit (micropower wireless communication unit and narrowband carrier communication unit). Through the hardware circuit modification of the communication unit installed in the smart electricity meter, the expansion of the power user electric energy data acquisition system communication protocol, and the upgrade of the software of electric energy data acquisition device, in the event of a power failure, the communication unit immediately generates a power failure event and actively reports it. This paper also proposes an reporting strategy about anti-false alarm and anti-collision, to ensure the effectiveness of single and transformer area blackout reporting, thereby realizing the active repair of power failure and improving the power supply service level.
