摘　　要：继电保护系统是电力系统安全运行的重要保障。传统的集中式调试需要现场逐一操作,存在效率低、成本高等显著问题。随着物联网技术的发展,远距离无线电(Long Range Radio,LoRa)通信因其长距离和低功耗特性,成为分布式调试的有效方式。文章提出一种基于LoRa通信的继电保护分布式调试方法,设计并实现LoRa通信模块集成、网络拓扑设计、数据传输控制、远程分布式调试及数据存储分析的完整流程。通过评估该方法在不同距离下的误码率、响应时间、故障定位准确率以及运营成本,并与其他方法进行对比,验证了其传输稳定性和成本效益,适用于广域覆盖且成本敏感的电力系统应用场景。Relay protection system is an important guarantee for the safe operation of power system.Traditional centralized debugging needs field operation one by one,which has obvious problems such as low efficiency and high cost.With the development of Internet of Things technology,Long Range Radio(LoRa)communication has become an effective way of distributed debugging because of its long distance and low power consumption.This paper proposes a distributed debugging method of relay protection based on LoRa communication,and designs and realizes the complete process of LoRa communication module integration,network topology design,data transmission control,remote distributed debugging and data storage analysis.By evaluating the bit error rate,response time,fault location accuracy and operating cost of this method at different distances,and comparing with other methods,its transmission stability and cost-effectiveness are verified,and it is suitable for wide-area coverage and cost-sensitive power system application scenarios.
