5G冗余双通道通信技术在配电网差动保护中的应用研究

Research on 5G redundant dual-channel communication technology in differential protection of distribution network

目前电流差动保护技术在配电网保护中的应用已经成熟。差动保护业务主要使用电力光纤专网承载,铺设费用高,易受外力破坏。为解决此类问题,提出使用两家运营商的5G无线网络替代电力光纤专网的技术方案,通过构建5G冗余双通道试验验证环境,分别对业务可靠性及网络性能进行测试。试验结果验证了将5G冗余双通道通信技术应用于配电网差动保护的可行性。方案为今后5G无线网络应用于配电网差动保护提供了数据参考与借鉴。

The differential protection technology in the protection of distribution networks has become mature.The differential protection service is mainly undertaken by power fiber optic private network,which is expensive to lay and can easily be damaged by external forces.Therefore,the paper proposes a technical scheme of using 5G wireless networks of two mobile communication operators to take the place of dedicated power fiber networks;moreover,it tests the service reliability and network performance by constructing a 5G redundant dual-channel test and verification environment.The test results verify the feasibility of 5G redundant dual-channel communication technology applied to differential protection of distribution network.The scheme provides a data reference and experience for the application of 5G wireless network in differential protection of distribution network in the future.
