【摘要】：在坚强智能电网所有结构中,智能变电站最为关键。自2009年7月以来,我国国家电网公司建设部着重进行两批试点工程。从2011年起,变电站进行了全面改革创新,所有老旧变电站都进行智能化改革。目前,国内66k V变电站都改革变成智能化变电站,改革的装置如下:第1是变电站自动化系统;第2是监控装置;第3是继电保护装置;第4是安全自动装置。由于变电站智能化受到广泛关注,使国内相关技术得到改善,让电子技术向前沿科技成长,同时一些设备逐步实现了智能化:第一个是变压器智能化;第二个是开关智能化;第三个是电子式互感器。这都为全智能化变电站的崛起做了充足的准备。通过充分运用智能化数字技术,让66k V智能变电站的每个单元和构架都被智能化,这些单元包括:第一个是信息采集;第二个是数据传输;第三个是分析处理;第四个是记录反馈;第五个是计量计费;第六个是输出响应。这些被智能化的构架包括:第一个是网络化通信;第二个是模型;第三个是统一通信协议;第四个是设备;第五个是自动化运行管理手段。符合IEC61850标准进行交互,实现智能化变电站的共享功能和交互功能。本文在现有智能变电站实际情况的基础上,做出符合要求的设计方案,并探索国内外智能化变电站状况,将智能化变电站和非智能化变电站进行比较,在已有的智能化技术上,做出符合国家要求的设备方案,最后研究得到实现变电站智能化的完整设计方案。为了实现智能化变电站高效率、高质量的特点,其设计方案要考虑自动保护功能,并且刚刚出厂之后的所有输变电设备要进行严格检查。本文最后部分讨论了智能化变电站在两个技术上的前景,这两个技术如下:一个是一次设备智能化技术;另一个是二次系统智能化技术。
[Abstract]:Among all the structures of the strong smart grid, intelligent substation is the most important. Since July 2009, the Ministry of Construction of State Grid Company has carried out two batch of pilot projects. Since 2011, the substation has been reformed and innovated in an all-round way, and all the old and old substations have been reformed intelligently. At present, 66 kV substations in China are reformed into intelligent substations. The reformed devices are as follows: first, substation automation system; second, monitoring device; third, relay protection device; and fourth, safety automatic device. Due to the widespread attention to substation intelligence, the domestic related technology has been improved, and the electronic technology has grown to the forefront of science and technology. At the same time, some equipments have gradually realized intelligence: the first is transformer intelligence, the second is switch intelligence, and the other is switch intelligence. The third is electronic transformer. This all for the full intelligent substation rise made sufficient preparation. By making full use of intelligent digital technology, every unit and frame of 66kV intelligent substation is intelligentized. These units include: the first is information collection, the second is data transmission, the third is analysis and processing; The fourth is record feedback; the fifth is metering and charging; and the sixth is output response. These intelligent frameworks include: the first is network communication; the second is model; the third is unified communication protocol; the fourth is equipment; and the fifth is automatic operation management. The sharing function and interactive function of intelligent substation are realized according to IEC61850 standard. On the basis of the actual situation of the existing intelligent substation, this paper makes the design scheme which meets the requirements, and explores the situation of the intelligent substation at home and abroad, compares the intelligent substation with the non-intelligent substation, and makes a comparison between the intelligent substation and the non-intelligent substation. Finally, the complete design scheme of intelligent substation is obtained. In order to realize the characteristics of high efficiency and high quality of intelligent substation, the automatic protection function should be taken into account in its design scheme, and all transmission and transformation equipment should be inspected strictly after it has just left the factory. The last part of this paper discusses the prospect of two technologies in intelligent substation. The two technologies are as follows: one is the intelligent technology of primary equipment and the other is the intelligent technology of secondary system.
