【摘要】：随着用电量的增加，供电质量日益成为人们关注的焦点。我国国民经济的迅速发展对配电网供电质量及经济运行指标等提出了更高的要求。城市电网改造的深入进行使10kV配电网络的供电可靠性有了较大的提高，但网络的复杂程度也随之提高，为了全面提高配网运营的各项技术经济指标，配电自动化系统的建设势在必行。电力一次、二次设备及电子和通讯技术的发展，也为城市配电网自动化的实施提供了条件。本文结合冠县配电网改造及配电自动化的实施对配电自动化所涉及到的一次网架改造、通讯系统建设、主站和分站系统设计及配电网故障定位问题给出详细说明。论文在深入研究分析国内外配网自动化技术发展背景的基础上，首先分析了配网一次系统的网架结构对实施配网自动化的影响，给出了冠县配电网一次系统的改造方案。较为详细地阐述了配网自动化系统的整体设计方案，给出了其软件、硬件体系结构。本文重点对配电自动化系统的功能进行了较全面的分析，包括数据采集和监控、配电网高级应用软件(网络拓扑、状态估计、潮流计算、网损计算、负荷预测等)、配电管理、负荷管理、实时数据资源管理、重合器的配电网故障定位、FTU的配电网故障定位等。本文给出的配电网自动化系统设计方案，符合配电网的实际情况，实现了设计目标。实践将会证明该系统功能完善，使用方便，完全满足实际需求，可进一步提高供电企业的管理水平。
[Abstract]:With the increase of electricity consumption, the quality of power supply has become the focus of attention.The rapid development of China's national economy has put forward higher requirements for power supply quality and economic operation index of distribution network.With the deepening of urban power network transformation, the reliability of 10kV distribution network has been greatly improved, but the complexity of the network has also increased, in order to improve the distribution network operation of the various technical and economic indicators,The construction of distribution automation system is imperative.The development of power primary, secondary equipment and electronic and communication technology also provides conditions for the implementation of urban distribution network automation.Combined with the transformation of distribution network in Guanxian County and the implementation of distribution automation, this paper gives a detailed description of the problems of the transformation of primary network, the construction of communication system, the design of main station and sub-station system, and the fault location of distribution network involved in distribution automation.On the basis of deep research and analysis of the development background of distribution automation technology at home and abroad, this paper first analyzes the influence of the grid structure of the distribution network primary system on the implementation of distribution automation, and gives the reconstruction scheme of the distribution network primary system in Guanxian.The whole design scheme of distribution network automation system is described in detail, and its software and hardware architecture are given.In this paper, the functions of distribution automation system are analyzed, including data acquisition and monitoring, advanced application software (network topology, state estimation, power flow calculation, network loss calculation, load forecasting, distribution management, etc.).Load management, real-time data resource management, distribution network fault location of reclosing unit FTU distribution network fault location.The design scheme of distribution network automation system presented in this paper accords with the actual situation of distribution network and realizes the design goal.It will be proved in practice that the system has perfect function, convenient use and can completely meet the actual demand, and can further improve the management level of power supply enterprises.
