【摘要】 建设坚强智能电网是我国电网建设的发展目标和方向。智能变电站是智能电网的重要环节,是建设智能电网必要的技术基础。近年来,智能变电站的建设成为当前变电站建设的热点,与之相关的一些应用技术也得到了迅猛发展,各地先后有多座不同电压等级的智能站投入运行。随着运行经验的不断积累及应用技术的不断改进成熟,在电力系统中必将有更多的智能变电站投入运行。本文依托110kV何桥变设计工程,首先通过查阅文献、现场调研深入了解国内外智能化变电站技术的发展和应用情况,掌握大量的资料信息。然后对智能变电站的基本特征、网络架构进行深入的研究,提出可行的智能变电站的网络设计方案。接着对电子式互感器、合并单元、智能终端及设备状态监测等智能站的关键应用技术进行了分析研究,重点对电子式互感器的原理、经济技术性能等进行分析,在此基础上提出电子式互感器的选型配置方案,还重点对开关设备的智能化方案进行了分析论证,提出切实可行的方案。本文最后针对江苏电网第一座110kV智能变电站何桥变的建设规模、接线方式、设备选型等资料进行搜集整理,结合江苏省内智能站的运行情况,对该站的网络结构、交换机组网方式以及电子式互感器、合并单元、智能终端等的选型配置进行了设计,完成了该站的一、二次设备的智能化设计方案。最后对该站在智能化建设过程的一些特殊问题如出口压板的设置等进行深入分析,提出解决方案。更多还原

【Abstract】 Building strong and smart grid is the development of power grid construction goals and direction. Smart substation is an important part of the smart grid. In recent years, the construction of smart substation become hot, some applications related technology has been rapid developed and has some smart substations put into operation. With the continuous accumulation of operational experience and sophisticated technology continues to improve, in the power grid will have more intelligent substation into operation.This article relies on110kV Heqiao substation design engineering, first through the literature, field survey and in-depth understanding of development and application of intelligent substation technology, have a lot of information.Then the basic characteristics of the smart substation, network infrastructure in-depth study, propose viable network of samrt substation design.Then the electronic transformer, merging units, intelligent terminals and equipment condition monitoring station critical applications such as intelligent technologies were analyzed, focusing on the principle of electronic transformer, economic and technical performance analysis based on this proposed electronic transformer selection configuration, also focused on the switchgear intelligent analysis and demonstration program was put forward practical solutions.Finally, for the Jiangsu Power Grid’s first110kV smart substation-Heqiao substation construction scale, wiring, equipment selection and other data collected, combined with intelligent station in Jiangsu province, the operating status of the stations of the network structure, network switches methods and electronic transformer, merging units, intelligent terminal, etc. selection configuration has been designed, completed the substation equipment intelligent design. At last, ananlyzed some special problems in the construction processes and proposed the solution.更多还原
