【摘要】：电力通信网是电力系统的重要基础设施,贯穿于电力工业生产的各个环节,电力通信网的建设完善关系到电网的优质、安全、经济运行,也为电网的调度自动化和管理现代化运营提供有力保障。县域电力通信网是电力通信网的重要组成部分,在国家电网公司加强建设县域电力通信网的背景下,本文结合廊坊大厂供电公司电力通信网的现状,开展对大厂供电公司电力通信网的建设研究。本文根据高压配电通信网、中低压配电通信网的现状对配电通信网存在的问题进行了分析；对配用电业务需求进行了分析；详细介绍了以太网无源光网络(EPON)、无线通信技术和电力线载波通信等相关电力通信网技术,通过对比分析这些通信组网技术的优缺点,确定在中压配电通信网采用EPON技术进行组网建设,并在相应线路敷设了ADSS光缆,保证EPON通信物理层的光纤成环,实现通信网络的保护。在低压配电通信网采用TD-LTE230技术建设覆盖大厂县域的无线专网,通过终端数量需求分析和环境测试,选取了4个基站站点建设无线专网,覆盖整个县域。最后进行了成效分析。大厂供电公司电力通信网的建设完善为该地区配电自动化、智能台区、用电信息采集等相关业务提供了传输通道,用电信息采集站点的通信覆盖率显著提高,本文的研究改造可为其他地区电力通信网的建设和优化提供参考。
[Abstract]:Power communication network is an important infrastructure of power system, which runs through every link of power industry production. The construction and perfection of power communication network is related to the high quality, safety and economic operation of power network. It also provides powerful guarantee for dispatching automation and modern management operation of power grid. The county electric power communication network is an important part of the electric power communication network. Under the background that the State Grid Company strengthens the construction of the county area electric power communication network, this paper combines the present situation of the power communication network of Langfang Dachang Power supply Company. To carry out research on the construction of power communication network of large power supply company. According to the current situation of high voltage distribution communication network and medium and low voltage distribution communication network, this paper analyzes the problems existing in the distribution communication network, and analyzes the demand of distribution service. The (EPON), wireless communication technology and power line carrier communication technology in Ethernet passive optical network are introduced in detail. The advantages and disadvantages of these communication networking technologies are compared and analyzed. It is determined that the EPON technology is used to construct the medium voltage distribution communication network, and the ADSS cable is laid on the corresponding lines to ensure the ring of the optical fiber of the EPON communication physical layer and to realize the protection of the communication network. The wireless private network covering Dachang county is constructed by using TD-LTE230 technology in low-voltage distribution communication network. Through the analysis of terminal quantity demand and environmental test, four base station stations are selected to build wireless private network, covering the whole county area. Finally, the effectiveness analysis is carried out. The construction and perfection of the power communication network of Dachang Power supply Company provides a transmission channel for the distribution automation, intelligent station area, power information collection and other related services in this area, and the communication coverage of the power information collection station has increased significantly. The research and transformation of this paper can provide reference for the construction and optimization of electric power communication network in other regions.
