摘　　要：随着科学技术的不断发展,变电站的智能化水平得以提高。变电站新增了智能机器人巡检、移动智能终端等多种业务,有线通信方式无法对移动终端进行高效地接入,可以采用无线通信接入设备来解决多种生产业务的通信接入问题。传统的Wi-Fi接入方式很难为智能变电站提供高质量的服务。基于此,提出了一种基于5.8 GHz LTE-U的变电站通信业务接入技术,该技术可以满足电网视频、无人巡检机器人、温湿度传感器等大带宽、高可靠和低时延传输要求。此外,它还具有快速信道接入机制和终端掉线自动重连机制,可以实现电网设备故障预警的快速响应。实际测量结果表明,基于5.8 GHz LTE-U的变电站通信业务接入技术各项测量数据全部达标,可以为实现智能电网应用提供强有力的支撑。With the continuous development of science and technology,the intelligent level of transformer substation has been improved.The substation has added a variety of services such as intelligent robot inspection,mobile intelligent terminal and so on.Unfortunately,the wired communication cannot provide efficient access service for mobile terminals.We can use wireless communication access equipment to solve the communication access problem of multiple production services.It is difficult for traditional WiFi access to provide high-quality services for intelligent substation.Therefore,a transformer substation communication service access technology is proposed based on 5.8 GHz LTE-U.This technology can meet the requirements of wide bandwidth,high reliability and low delay transmission for power grid video,inspection robot,temperature and humidity sensor.In addition,it also has fast channel access mechanism and automatic reconnection mechanism,which can realize the fast response to the power grid equipment fault early warning.The actual measurement results show that all measurement data of substation communication service access technology based on 5.8 GHz LTE-U are up to standard,which can provide strong support for the application of smart grid.
