考虑通信流量控制的配电网线路5G差动保护方案OACSTPCD

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.
