摘　　要：大规模分布式新能源接入配电网,影响了传统配网保护的正确性。文章在分析分布式电源对配电网保护影响的基础上,提出了基于5G通信的有源配电网继电保护方案及基于5G的配电网差动保护解决保护的选择性与正确性的问题。基于5G的防孤岛保护可显著提升防孤岛保护的动作时间。Large-scale distributed new energy is connected to the distribution network,which affects the correctness of the traditional distribution network protection.Based on the analysis of the influence of distributed power supply on the protection of distribution network,this paper proposes a relay protection scheme of active distribution network based on 5G communication.The differential protection of distribution network based on 5G solves the problem of selectivity and correctness of protection.Anti-island protection based on 5G significantly improves the action time of anti-island protection.
