【摘要】 配电网络是电力系统中直接为广大用户分配电能的重要环节，其运行稳定性、可靠性等直接影响广大用户的生产与生活。随着社会的发展与人民生活水平的不断提高，人们对供电质量与可靠性提出了更高要求。实现配电网络馈线自动化，进一步提高电网配电部分的运行管理水平已是当务之急。 本论文对配电网络进行了系统的研究与分析，比较了目前适用于馈线自动化系统的各种方案，并重点讨论了通用型基于馈线终端单元(FTU)的分层分布式馈线自动化(FA)系统的研究内容。 结合配电网络实际，选用图算法作为研究馈线自动化系统的算法理论依据被证明是比较适宜的处理方案。本论文基于变结构耗散网络理论，详细讨论了基形变换、形基变换、点弧变换、弧点变换、过热弧搜寻、负荷分配、负荷均衡化以及优化恢复非故障停电区域供电等一系列与馈线自动化功能相关的处理算法。本文作者还进一步发展该理论，提出解决配电网络常见特殊接线馈线自动化功能的一种新方案。 本论文还进一步研究了馈线自动化系统管理程序的构成，并详细分析了其中图形组态模块、数据库模块以及算法处理模块的实现，简述了不在本文作者工作范围内的通讯模块、报表模块的实现思想。以此为指导，本文作者利用Visual C++6.0及SQL Server 2000等工具开发出一套开放式管理程序，经应用证明具有较强的可靠性、灵活性与实用性。更多还原

【Abstract】 Power distribution network is an important component in power system which directly distributes power energy to the users. It’s operational stability and reliability seriously influences the user’s production and life. With the social development and improvement in people’s living standard, people makes greater demands on energy quality and reliability. It’s very urgent to realize distribution feeder automation for the sake of higher operational and managing level in distribution network.This thesis makes a systematic reaserch and analysis about distribution network, compares some schemes about realizing feeder automation system and discusses the universal layered and distributed feeder automation sheme which based on feeder terminal unit(FTU) in detail.Combined with the practical situiation in distribution network, it’s suitable to select graph algorithm as the theoretical algorithm base. Based on structure variable dissipated network theory, this thesis detailedly discusses the transforms of base-to-shape, shape-to-base, vertex-to-arc, arc-to-vertex, over-heated arc dectection, load allotting, load balancing and optimum restoration. The author developes this theory and brings forward a new method to solve feeder automation algorithm for processing special distribution network connection.This thesis studies the architecture of feeder automation management program further, and analyses the graphics configuration module, the database module and the algorithm module. The communication module and report module are also discussed. Based on these, the author makes use of Visual C++ 6.0 and SQL Server 2000 to develop an open management program. It is proved to be reliable, flexible and practical in practical use.更多还原
