【摘要】：促进清洁能源利用、保障能源安全稳定、提高能源使用效率已经成为当今能源发展的新趋势。智能变电站是智能电网中的重要中间环节,智能变电站的技术水平直接影响着智能电网建设水准。因此,对智能变电站设计进行系统性研究,形成先进合理的设计方案,对智能电网以及智能变电站建设具有重要意义。智能变电站一方面提高供电可靠性,另一方面通过提升设备智能化程度减少了后期运维投入。按照规划,北京新机场将建设两座110kV中心变电站,均按照智能变电站标准进行设计,计划于2019年建成投运。民用机场用电属于一级用电负荷,其对于供电保障要求具有极大的安全性、可靠性、稳定性,因此,研究北京新机场110kV智能变电站具有重要意义。本论文以北京新机场即将建设的二号110kV中心变电站为研究对象,主要工作如下:首先介绍了智能电网、智能变电站的发展背景、国内外研究现状;其次,阐述了智能变电站的概念与主要技术特征;对智能变电站的几个核心技术进行了研究,包括:IEC 61850标准的内容与特点等、网络通信结构、一体化监控系统,为后文的一、二次方案研究提供基础;随后,对北京新机场二号110kV站的初步设计方案中的一、二次设计部分进行了研究,着重分析了智能变电站的网络通信结构,对比分析各种网络结构特点,选取最适合的网络结构,同时,对比了智能变电站与传统变电站的站用电源系统,分析智能变电站一体化电源系统优势,完善了设计内容;最后对110kV智能变电站的设计研究进行了总结,并对论文未完善的地方提出了研究方向。
[Abstract]:It has become a new trend of energy development to promote clean energy utilization, ensure energy security and stability, and improve energy use efficiency. Intelligent substation is an important intermediate link in smart grid. The technical level of intelligent substation directly affects the level of smart grid construction. Therefore, the systematic research on intelligent substation design and the formation of advanced and reasonable design plan are of great significance to the construction of smart grid and intelligent substation. On the one hand, the intelligent substation improves the reliability of power supply, on the other hand, it reduces the later operation and maintenance investment by improving the intelligent degree of the equipment. According to the plan, Beijing's new airport will build two 110kV central substations designed according to smart substation standards, and will be put into operation by 2019. Civil airport power consumption belongs to the first class power load, which has great security, reliability and stability for power supply guarantee. Therefore, it is of great significance to study the 110kV intelligent substation of Beijing New Airport. The main work of this thesis is as follows: firstly, the smart grid, the development background of smart substation, the research status at home and abroad are introduced. Secondly, the concept and main technical features of intelligent substation are expounded. Several core technologies of intelligent substation are studied, including: the content and characteristics of IEC 61850 standard, network communication structure, integrated monitoring system, which provides the basis for the later primary and secondary project research; Then, the primary and secondary design of Beijing New Airport No. 2 110kV Station is studied. The network communication structure of intelligent substation is analyzed, and the characteristics of various network structures are compared and analyzed. Select the most suitable network structure, at the same time, compare the station power supply system between intelligent substation and traditional substation, analyze the advantages of intelligent substation integrated power supply system, improve the design content; Finally, the design and research of 110kV intelligent substation are summarized, and the research direction is put forward.
