摘　　要：电力无线专网作为电网生产控制类业务的重要通信方式,需要满足对业务终端冗余覆盖,并克服同频干扰的建设要求。首先,文章对标准蜂窝结构和实际网络场景下的冗余覆盖效果进行仿真分析,然后,介绍常见的抗同频干扰技术方案,最后,针对电力无线专网2个典型业务应用场景,分别进行同频和异频组网的仿真分析,并由此提出一种根据电力业务分布场景进行频率组网的架构,实现电力无线业务高可靠、高质量传输的效果。Power wireless private network as an important communication infrastructure for electricity production control business needs to meet the redundant coverage of service terminals and overcome co-frequency interference.In this paper,the redundant coverage effect in the standard cellular structure and actual scenario are simulated and analyzed first.Then,several popular anti-co-channel interference solutions are introduced.Lastly,the simulation analysis of the co-frequency and inter-frequency networking for the two typical scenarios in the power wireless private network are carried out,besides,an architecture for differ-frequency networking according to the power service distribution scenario is proposed,which achieves the effect of highly reliable and high-quality transmission of power wireless services.
