Abstract

In this paper, we propose a 5G dual-channel hot standy transmission scheme for distribution grid differential protection. Two 5G communication links are established for protection devices on both sides, and link delay monitoring heartbeat packets are sent at 1kHz frequency. Protection device can obtain each 5G communication link delay sampling value by monitoring the heartbeat packet round-trip delay. Through the time series analysis technology, one can calculate time delay variation of each 5G communication link. By doing so, we can predict the 5G transmission delay fluctuations caused by variational wireless channel environment. According to the real-time forecast results of each communication link, the protection device can decide to select which 5G link and switch to the better one before the transmission delay deteriorates. The efficient transmission of differential protection can guarantee the instantaneity, reliability and accuracy of fault removal of the distribution grid. As a result, we can improve the quality of power supply service.

一种面向电网控制业务的5G双路热备传输方案

本文提出了一种用于配电网差动保护的5G双通道热备传输方案。双方保护设备建立两条5G通信链路，以1kHz频率发送链路延时监测心跳包。保护设备通过监控心跳报文的往返时延，获取各5G通信链路时延采样值。通过时间序列分析技术，可以计算出5G通信各链路的时延变化。这样，我们可以预测由于无线信道环境的变化而引起的5G传输延迟波动。根据各通信链路的实时预测结果，保护装置可以在传输延迟恶化之前决定选择哪个5G链路并切换到较好的链路。差动保护的高效传递可以保证配电网故障排除的即时性、可靠性和准确性。从而提高供电服务质量。
