Abstract

The research on delay compensation and reliability verification of distribution network differential protection based on 6G communication aims to solve the problems of accurate action and stable operation of distribution network protection systems in high-bandwidth and low-latency environments. This paper constructs a differential protection model integrating the ultra-low latency characteristics of 6G, and proposes a multi-dimensional delay compensation algorithm. Through real-time link quality perception and dynamic weight adjustment, the rapid synchronization and accurate triggering of protection signals are realized. In terms of reliability verification, multi-scenario simulations and hardware-in-the-loop experiments are used to evaluate the correct action rate and response time of protection under different network loads, interferences, and fault conditions. The results show that this method significantly improves the robustness and action accuracy of distribution network differential protection in 6G communication environments, providing a theoretical basis and practical reference for the design and engineering application of future smart grid protection systems.
