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 transmission 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 current transformer (CT), significantly reducing data flow without compromising the performance of differential protection. 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.
