STYLEREF 标题 1 摘 要 PAGE PAGE 8 摘 要 变电站是输配电执行系统的最终设备，随着其对系统要求的不断提升，对信息的供给也不断增加，因此，当前的变电站需要一个智能的、简约的系统，以便能够进行信息的共享，从而降低投资，提升维修的效率。在当前的形势下，随着微机技术的不断进步，智能化的变电所已经离我们更近了一步。 为了解决目前国内外电力系统在智慧配电系统中所面临的信息交流、系统整合等方面的问题，采用模块化技术进行了研究。在对模块化智能变电站的关键技术进行了进一步的讨论之后，本文提出了几种切实可行的解决方法和建议。通过对二次装置模块的应用，得出了二次装置模块化的结论，并对二次装置模块的应用进行了探讨。在此基础上，对原始数据进行了分析，并对一次部分的主接线进行了设计，同时对其进行了对比，最终选出了最优的方案。并确定了主变压器的容量和运行次数；然后，通过对短路点的短路分析，得出短路电流，在此基础上，完成了系统的抗雷击、继电保护等功能的实现。 关键词：模块化；主接线；短路计算；继电保护；智能化 STYLEREF 标题 1 摘 要 Abstract Substation is the final equipment of the transmission and distribution execution system, as its requirements for the system continue to increase, the supply of information is also increasing, therefore, the current substation needs an intelligent, simple system to be able to share information, thereby reducing investment and improving the efficiency of maintenance. Under the current situation, with the continuous advancement of microcomputer technology, intelligent substations have been one step closer to us. In order to solve the problems of information exchange and system integration faced by domestic and foreign power systems in the intelligent power distribution system, modular technology is used to study. After further discussion of the key technologies of modular intelligent substations, this paper proposes several practical solutions and suggestions. Through the application of the secondary device module, the conclusion of the modularization of the secondary device is drawn, and the application of the secondary device module is discussed. On this basis, the original data was analyzed, the main wiring of the primary part was designed, and it was compared to finally select the optimal scheme. On this basis, the capacity and number of runs of the main transformer are determined; Then, through the short-circuit analysis of the short-circuit point, the short-circuit current is obtained, and the high-voltage device is selected, on this basis, the realization of the systems li
