【摘要】 由于电力系统业务的特殊性,对其传输网络有低时延和高安全性的要求。5G网络切片以其多样化服务和隔离性为电力通信场景提供可能。文章分析了主要电力系统业务的指标要求,对电力切片的网络规模和结构进行了仿真研究,对电力系统业务的时延特性进行对比分析。仿真结果表明,网络切片技术可以很好地降低电力系统业务的传输时延,对电力系统通信有较强的适应性,但并不能达到所有业务的时延要求。最后,对业务端到端时延的概率密度进行分析,得出近似服从正态分布的结论。更多还原

【Abstract】 Due to the particularity of the power system services, there is a requirement for low transmission delay and high security for its transmission network. 5G network slicing offers the potential application for power communication scenarios with its diverse services and isolation. This paper analyzes the index requirements of major power system services, simulates the network scale and structure of power slicing, and compares the delay characteristics of power system services. The simulation results show that the network slicing technology can reduce the transmission delay of power system services and has strong adaptability to power system communication, but it can not meet the delay requirements of all services. Finally, the probability density of the end-to-end delay of the business is analyzed, and the conclusion that the approximate distribution follows the normal distribution is obtained.更多还原
