【摘要】：变电站是发电和用电环节之间的桥梁，在电力系统中发挥着至关重要的作用，智能变电站是坚强智能电网的重要组成部分。各站信息一体化、二次设备网络化以及辅助系统智能化是现阶段智能变电站的主要特点，如何使智能变电站的智能更加坚强和全面，是一个值得人们关注的问题。物联网技术可以使变电站内部的物与物相连、人与物相连，为智能化提供了很好的依托。近年来，物联网技术在智能变电站中得到应用，随着电力通信网络逐步向IPv6过渡，智能变电站对IP地址的需求也将越来越迫切。当前，全球IP地址池中地址已分配完毕，，IP地址资源不足将严重制约着物联网产业的发展。课题以国网电力科学研究院2012年科技项目——基于物联网技术的智能变电站辅助系统深化研究为依托，主要研究物联网和IPv6技术在智能变电站中的应用。首先简要说明了课题相关技术的国内外现状及发展趋势，参照电力物联网架构，设计出一种可以管控多个变电站的智能变电站辅助控制系统，并详细介绍了系统的设计思想和关键技术；其次以IPv6为接入网，在系统感知层探讨IPv6接入技术，对感知节点入网问题进行探索，提出使用感知服务器对其进行辅助，实现数据转换。最后概括了智能变电站辅助系统的功能，通过系统功能实现和对比，显示出采用物联网和IPv6技术的智能变电站辅助系统具备先进性和前瞻性。物联网和IPv6技术应用于智能变电站中可以解决目前变电站的温湿度监测、安防报警、图像视频监控等辅助生产系统各自独立而形成的信息孤岛、反应时间慢、人工巡视工作量大等问题，从而达到智能运行管理的要求。该课题的研究是对物联网各个层次核心技术的推进，是对电力通信网向下一代互联网过渡的初步探索。
[Abstract]:Substation is a bridge between power generation and power consumption, which plays an important role in the power system. Intelligent substation is an important part of a strong smart grid. The main characteristics of intelligent substation at present are the integration of information, the networking of secondary equipment and the intelligence of auxiliary system. How to make the intelligent substation more strong and comprehensive is a problem that people should pay attention to. The technology of Internet of things can make the inside of substation connected with things and people and objects, which provides a good support for intelligence. In recent years, Internet of things technology has been applied in intelligent substation. With the gradual transition of power communication network to IPv6, the demand for IP address in intelligent substation will become more and more urgent. At present, the lack of IP address resources in IP address pool has seriously restricted the development of Internet of things industry. The subject is based on the research of intelligent substation auxiliary system based on Internet of things, which is a 2012 science and technology project of China Power Research Institute. The application of Internet of things and IPv6 technology in intelligent substation is mainly studied. Firstly, this paper briefly describes the current situation and development trend of the related technologies at home and abroad, and designs an intelligent substation auxiliary control system which can control multiple substations according to the power Internet of things architecture. The design idea and key technology of the system are introduced in detail. Secondly, with IPv6 as the access network, the IPv6 access technology is discussed in the system perception layer, the problem of the perceptual node access is explored, and the use of the perceptual server to assist the system is put forward. Data conversion is realized. Finally, the functions of the intelligent substation auxiliary system are summarized. Through the realization and comparison of the system functions, it is shown that the intelligent substation auxiliary system based on the Internet of things and IPv6 technology is advanced and forward-looking. The application of Internet of things and IPv6 technology in intelligent substation can solve the problem of information isolated island formed by the auxiliary production systems such as temperature and humidity monitoring, security alarm, image and video surveillance and so on, and the reaction time is slow. The workload of manual inspection is large, so as to meet the requirements of intelligent operation management. The research of this topic is to advance the core technology of the Internet of things at all levels and to explore the transition from the power communication network to the next generation Internet.
