摘　　要：随着电力系统规模扩大和复杂度提升,传统继电保护测试方法已不能满足测试需求,存在效率低、成本高等问题。文章设计基于5G通信技术的变电站继电保护分布式测试系统,充分利用5G通信技术的高速率、低时延特性,采用分布式架构,实现继电保护装置的精准测试。系统由分布式数据采集、数据传输、继电保护测试以及测试结果分析4个功能模块组成。实验结果表明,该系统在测试效率、数据传输速率、测试精度以及故障诊断准确率等方面均优于传统方法,为变电站继电保护测试提供了新的技术路径。With the expansion and complexity of power system,traditional relay protection testing methods can no longer meet the test requirements,and there are problems such as low efficiency and high cost.This paper designs a distributed test system for substation relay protection based on 5G communication technology,which makes full use of the high-speed and low-delay characteristics of 5G communication technology and adopts distributed architecture to realize accurate test of relay protection devices.The system consists of four functional modules:distributed data acquisition,data transmission,relay protection testing and test result analysis.The experimental results show that the system is superior to the traditional methods in test efficiency,data transmission rate,test accuracy and fault diagnosis accuracy,which provides a new technical path for substation relay protection testing.
