【摘要】：伴随国网保定供电公司智能电网的快速发展和集约化不断深入,电力系统配网自动化、应急抢修、输电在线监测等业务接入需求呈现分布广、种类多、运行状态复杂、自然条件恶劣等,对现有保定电力通信系统容量和能力提出了严峻考验。有线通信形式存在布线限制、组网灵活性低、升级扩展不便、安装维护困难、光缆建设、租用成本高等问题。本文对长期演进技术(Time Division Long Term Evolution,TD-LTE)无线专网对电力系统各业务承载和应用进行研究。首先,对电力系统配电自动化、用电信息采集、智能电网用户服务、应急抢修检修管理等业务发展规模、传输带宽要求及业务特点进行调研分析,对TD-LTE无线专网覆盖能力、业务承载能力、信息安全、传输特性、可靠性等技术进行分析。然后对TD-LTE无线专网的整体架构、核心网网络寻址、核心网IP地址、策略控制和业务质量保证进行规划设计,最后在保定供电公司在现有的传输网和综合数据网基础上,为提高保定配电自动化覆盖率,建成满足信息化、自动化、互动化为特征的坚强智能电网,实现配电网调度主站和配电终端设备之间可靠安全的信息传输。部署4G(第四代移动通信技术)无线通信系统,为用电信息采集(包含电动汽车充电站、充电桩的信息采集、中小用户信息采集)、配网自动化、输电在线监测、应急抢修、移动办公等业务提供灵活的通信服务,为增大通信容量,全面提高通信接入能力和提高通信网络稳定可靠性,提供应急备用高带宽的无线通道。保证了通信系统的安全、可靠、稳定、经济运行。
[Abstract]:With the rapid development and intensive development of the smart grid of Baoding Power supply Company, the power system distribution automation, emergency repair, transmission on-line monitoring and other business access requirements are widely distributed, many kinds, complex operation state, etc. The capacity and capability of the existing Baoding electric power communication system are severely tested by the bad natural conditions. Cable communication is limited in wiring, low flexibility in networking, inconvenience in upgrading and expansion, difficulty in installation and maintenance, construction of optical cables, high rental cost and so on. In this paper, time Division long term Evolution (TD-LTE) wireless private network is used to study the load bearing and application of power system services. First of all, the development scale, transmission bandwidth requirements and service characteristics of power system distribution automation, power information collection, smart grid user service, emergency repair and maintenance management are investigated and analyzed, and the coverage capacity of TD-LTE wireless private network is analyzed. Service carrying capacity, information security, transmission characteristics, reliability and other technologies are analyzed. Then the overall architecture of TD-LTE wireless private network, core network addressing, core network IP address, policy control and service quality assurance are planned and designed. Finally, on the basis of existing transmission network and integrated data network, Baoding Power supply Company, In order to improve the coverage rate of distribution automation in Baoding, build a strong smart grid which can meet the needs of information, automation and interaction, and realize the reliable and safe transmission of information between the main station of distribution network and the distribution terminal equipment. Deployment of 4G (fourth generation mobile communication technology) wireless communication system for power information collection (including electric vehicle charging station, charging pile information collection, small and medium user information collection), distribution network automation, transmission on-line monitoring, emergency repair, Mobile office and other services provide flexible communication services, in order to increase the communication capacity, improve the overall communication access capacity and improve the reliability of the communication network, provide emergency standby high bandwidth wireless channels. Ensure the security, reliability, stability and economic operation of the communication system.
