面向配电网业务的5G通信技术适配性研究

Research on 5G Communication Technology Adaptation for Distribution Network Business

配电网的网络结构复杂,开关数量众多,致使各开关间的保护配合相对困难,往往造成非故障线路的陪停。针对现有配电网自愈系统成本高、自愈时间长的问题,以5G通信网络为数据传输通道,提出了基于5G通信模式下的配电网自愈保护方案,解决配网开关保护级差配合的时间问题,使故障切除时间缩短至毫秒级,并通过实例验证了配电网自愈保护策略的正确性。

The complex network structure of distribution network and the large number of switches make it relatively difficult to cooperate with the protection of each switch,which often results in the accompanying stop of non-faulty lines.Aiming at the problems of high cost and long self-healing time of the existing distribution network self-healing system,a self-healing protection scheme for distribution networks based on the 5G communication mode is proposed using the 5G communication network as the data transmission channel to solve the time problem of the protection level difference coordination of the switching protection of the distribution network,so as to shorten the fault resection time to milliseconds,and the correctness of the self-healing protection strategy of the distribution network is verified by examples.
