【摘要】：随着电力技术的不断发展,配电网自动化系统的功能也日趋完善,开始广泛应用于配电网建设当中,大家对强化电能品质、电网构建、电网科学平稳运转及优良服务能力提出了更高要求。配电系统作为构建坚强智能电网的六大核心步骤的一个方面,是坚强智能电网的关键根基及重要内容。依照先进国家的科学做法,先进的配电网自动化系统是增强配电网监管能力,提升供电水平、质量及稳定性,达到科学经济运转的前提,也是实现智能配电网目标的关键。针对原有配网自动化系统存在的明显不足,结合城区配电网改造,曲阜供电公司对配网自动化系统进行升级改造。我有幸参与此项工程的设计工作,利用所学知识,深入钻研,收获颇多。本文首先介绍了配电网自动化系统方面的基本知识,对该系统进行了解,指出曲阜城区配电网自动化系统升级改造的必要性。基于配电自动化主站的功能不足,城区配电系统供电可靠率较低的情况,设计了配电网网架及一次设备、配电自动化主站系统、馈线自动化、配电终端及相关的配电通讯网与配电信息集成应用等方面的详细改造方案,最后对改造后的曲阜城区配网自动化系统的实际应用情况进行了分析与测试。详细分析了配电网一次网架及设备、配电网自动化系统、馈线自动化等方面升级后实际应用的情况,并对系统整体实际运行成效进行了分析。曲阜城区配电网自动化工程的成功实践,说明配电自动化建设将推动配电网生产运行管理模式的改造,提高配电网的供电可靠性和运行经济性,提升配电网的运行管理水平和供电服务质量,不仅具有显著的经济效益,而且会带来巨大的社会效益。配网自动化系统的应用,使得曲阜配网工程的科技含量和技术水平大大提升,明显增强供电稳定性,且在智能配电网、调控一体化层面展开认真研究及分析。由一年来的实际运行情况能够得出,改造后的曲阜城区配电网自动化系统显著提高了供电可靠性,达到了预期目标,大大提升了配电网的运行管理水平和供电服务质量,在曲阜城区配电网的常态运转及监管方面发挥了巨大作用。该系统借助了先进的技术和设施及稳定的通讯网络,今后将在曲阜社会经济的发展当中产生巨大效益。
[Abstract]:With the continuous development of power technology, the function of distribution network automation system is becoming more and more perfect. It has been widely used in distribution network construction. The scientific and smooth operation of the power grid and its excellent service capability put forward higher requirements. Distribution system is one of the six core steps in building a strong smart grid. It is the key foundation and important content of the strong smart grid. According to the scientific practice of the advanced countries, the advanced distribution network automation system is to enhance the supervision ability of the distribution network, improve the level, quality and stability of the power supply, To achieve the premise of scientific and economic operation is also the key to achieve the goal of smart distribution network. In view of the obvious shortcomings of the original distribution automation system, combined with the transformation of urban distribution network, Qufu Power supply Company has upgraded the distribution network automation system. I have the honor to participate in the design of this project, using the knowledge learned, in-depth research, a lot of gains. First, this paper introduces the basic knowledge of distribution network automation system, Based on the understanding of the system, the necessity of upgrading and reforming the distribution network automation system in Qufu City is pointed out. Based on the insufficient function of the main station of distribution automation, the reliability of power supply of the distribution system in the urban area is low. The detailed retrofit schemes of distribution network frame and primary equipment, main station system of distribution automation, feeder automation, distribution terminal and related integrated application of distribution network and distribution information are designed. Finally, the practical application of the reformed distribution automation system in Qufu district is analyzed and tested. The primary network structure and equipment of the distribution network are analyzed in detail, and the distribution network automation system is analyzed in detail. The actual application of feeder automation after upgrading, and the actual operation results of the system as a whole are analyzed. It is shown that the construction of distribution automation will promote the transformation of production and operation management mode of distribution network, improve the reliability and economy of distribution network, improve the level of operation management and service quality of distribution network, and not only have remarkable economic benefits. And it will bring great social benefits. The application of distribution automation system makes the science and technology content and technical level of Qufu distribution network project greatly improved, obviously enhance the stability of power supply, and in the smart distribution network, From the actual operation in the past year, it can be concluded that the reformed distribution network automation system in Qufu district has significantly improved the reliability of power supply and achieved the expected goal. It has greatly improved the management level of distribution network and the quality of power supply service, and has played a great role in the normal operation and supervision of the distribution network in Qufu City. The system has benefited from advanced technology and facilities, as well as a stable communication network. In the future in Qufu social and economic development will produce tremendous benefits.
