【摘要】：随着社会现代化进程的不断拓展,配网自动化已逐步成为电力应用技术部门用来缓解电力能源紧张问题与满足高质量用电需求等而研究开发的新技术。国家电网明确提出要在我国管辖范围内大力发展智能电网,构建强化智能电网。智能配网建设范围主要涵盖中低压电网,所面对的多数为城市居民、企业等用户,同时加固配网网架结构,削减配网运行中的薄弱点、卡脖子区域,将主网与用户故障隔离开,增强配网故障发现与处理水平,迅速恢复电力用户的正常用电。可以看出,配网自动化在城市中成功应用的意义重大,但由于各个城市发展水平受当地政治经济因素影响较大,城市规划、发展方向等存在不确定因素,因此,配网自动化在应用模式上会存在结构上差异、管理模式上的不同、应用设备上的差异以及运行水平的不同等等。与此同时,随着社会对供电服务及其可靠程度要求越来越高,原有的的配网架设结构及其管理等已不能满足现有新的需求,配网自动化管理成为解决这一问题的有效途径并迅速发展起来。然而其适用形式随地域而变化,本文将重点研究与讨论配网自动化在城市中的应用。本文开篇先介绍了课题的研究意义、现状及其建设要求；其次,文章就有关配网自动化的一些理论进行阐述；再次以淄博配网自动化的实践应用为具体案例,分析该地区配网实际发展现状,为探索出适合相似城市智能电网发展的途径、方法奠定基础,力求建设好城市配网,争取在供电方面达到高标准服务和高水平能力；然后详细介绍了淄博配网自动化的建设方案,而且指出这一方案需要按照一定原则来实施；文章最后就课题的应用与研究成果进行阐述和展望。配网自动化不仅有利于提高电力资源的利用率,在—定程度上缓和了供电紧张问题,而且有利于提高电力服务水平。在城市实施配网自动化,对市级供电行业的发展有很大的促进作用,也能够有效提升该区域的经济效益。自动化程序的具体实施是通过监视与控制配网来完成的,其可以促进倒闸操作的高效进行,保证员工劳动效率与安全；能够很大程度上提升供电水平、拓展电力行业的发展。配网自动化系统的建成不仅有利于故障定位及隔离,还能够迅速自动恢复正常供电,大幅度降低故障危害程度,有利于保证电力系统的安全可靠运行,缩短处理故障时间,提高系统供电水平,为用户提供便利；而且配网自动化建设还能提高电能质量,减少资源浪费与供电风险,提升供电可靠程度。
[Abstract]:With the development of social modernization, Distribution network automation has gradually become a new technology developed by the electric power application technology department to alleviate the shortage of power energy and meet the demand of high quality electricity. The State Grid has clearly proposed to vigorously develop the smart grid within the jurisdiction of our country. Building a strengthened smart grid. The scope of smart distribution network construction mainly covers medium and low voltage power grids, facing most of the urban residents, enterprises and other users. At the same time, strengthen the distribution network structure, reduce the weak points in the operation of the distribution network, the neck area, By isolating the main network from the users' faults, enhancing the level of fault detection and processing in the distribution network, and rapidly restoring the normal power consumption of the power users, it can be seen that the successful application of distribution network automation in the city is of great significance. However, because the development level of each city is greatly influenced by local political and economic factors, and there are uncertain factors in urban planning and development direction, the distribution network automation will have structural differences in application mode and different management mode. At the same time, with the increasing demands of the society on power supply services and their reliability, the original distribution network erection structure and its management can no longer meet the existing new needs. Distribution network automation management has become an effective way to solve this problem and has developed rapidly. This paper will focus on the study and discussion of the application of distribution network automation in cities. At the beginning of this paper, the research significance, current situation and construction requirements of the topic are introduced. Secondly, some theories about distribution network automation are expounded in this paper. Thirdly, taking the practical application of distribution network automation in Zibo as a concrete case, this paper analyzes the actual development situation of distribution network in this area, and lays a foundation for exploring the way to develop smart grid suitable for similar cities, and makes every effort to build a good distribution network in the city. In order to achieve high standard service and high capability in power supply, this paper introduces the construction plan of Zibo distribution network automation in detail, and points out that this scheme needs to be carried out according to certain principles. At the end of the paper, the application and research results of the project are expounded and forecasted. The automation of distribution network is not only helpful to improve the utilization ratio of power resources, but also alleviates the problem of power shortage to a certain extent. In addition, it is beneficial to improve the level of electric power service. The implementation of distribution automation in cities will greatly promote the development of the municipal power supply industry. It can also effectively improve the economic benefits of the area. The implementation of the automation program is accomplished by monitoring and controlling the distribution network, which can promote the efficient operation of the switch and ensure the labor efficiency and safety of the staff. It can greatly improve the power supply level and expand the development of the power industry. The establishment of the distribution network automation system is not only conducive to fault location and isolation, but also can quickly and automatically restore the normal power supply, and greatly reduce the degree of fault damage. It is beneficial to ensure the safe and reliable operation of the power system, shorten the time to deal with the failure, improve the power supply level of the system, and provide convenience for the users. Moreover, the automation construction of the distribution network can also improve the power quality, reduce the waste of resources and the risk of power supply. Improve the reliability of power supply.
