随着智能电网的快速发展和全面部署,电力系统通信网络结构也发生了变化,除了传统的电力通信方式外,新的通信方式也在逐步推广。原有的光纤通信对带宽需求更加迫切,骨干网通信容量持续提升,输电线路在线监测系统、配电网自动化系统、电网应急指挥系统和输电线路监测等业务,对无线通信的需求非常迫切。对电力系统无线通信传输中的信道模型进行研究,通过现场数据收集和试验模拟,改进了适合电力系统智能变电站内适用的信道模型,为无线通信系统的数据传输和智能电网的无线通信部署提供技术支撑。
With the rapid development and full deployment of smart grid, the structure of power system communication network has also changed. In addition to the traditional power communication methods, new communication methods are gradually being popularized. The original optical fiber communication is more and more urgent to the bandwidth demand, the communication capacity of the backbone network continues to improve, the on-line monitoring system of transmission line, automation system of distribution network, emergency command system of power grid and transmission line monitoring and other services are in urgent need of wireless communication. The channel model of power system wireless communication transmission is studied. Through the field data collection and experimental simulation, the suitable channel model in power substation intelligent substation is improved, which provides technology for data transmission in wireless communication system and wireless communication deployment in smart grid support.
