摘要
针对5G通道承载配电网线路差动保护业务时数据流量大的问题,提出了考虑通信流量控制的配电网线路5G差动保护方案.从差动数据的发送频率、报文内容和报文类型入手,优化发送策略、简化数据格式、提高报文效率,并在此基础上优化差动保护数据同步方案和CT(电流互感器)饱和判别逻辑,大幅降低了数据流量,且不影响差动保护的性能,同时仍具备通道监视的功能.最后通过实验验证了该方案具备工程应用推广价值,为5G通信技术承载配电网差动保护业务的实用化提供了借鉴.
Abstract
To address the issue of large data flow of 5G channel for differential protection of distribution lines,a 5G-based scheme for differential protection for distribution lines considering data flow control is proposed.This scheme optimizes transmission strategy,streamlines data formats,and boosts message efficiency by focusing on the trans-mission frequency,message content,and message types of differential protection data.Furthermore,it enhances the data synchronization scheme for differential protection and refines the logic for saturation discrimination of cur-rent transformer(CT),significantly reducing data flow without compromising the performance of differential protec-tion.Through experiments,the scheme's viability for practical applications has been confirmed,offering valuable insights for the real-world deployment of 5G-enabled differential protection for distribution networks.
