【摘要】：智能电网被公认为是解决当前电力系统在安全、智能、环保等多方面问题上最有效的方案，与此同时智能变电站是建设坚强智能电网的核心环节和基本要素。 智能电网的是以统一性和开放性为根本的。本文先具体分析了传统变电站的优势和劣势然后将传统变电站和智能化的变电站进行类比分析得出，在结构的组成和功能实现上两者之间有巨大差别，进而提出了以传统变电站为基础对一、二次设备的智能化的变电站建设改造方案，还对该变电站的结构的技术特点进行分析并阐述了它对未来电网的深远意义。本文在保持现有基本构架不产生变化的同时，基于现有变电站设计出一种可以采集数字化的基本信息的统一化平台结构，通过这种结构使信息协议标准化，电网系统更加稳定，管理更加统一，，时间同步等，最后借由一级级的联络完成拓展整个电网信息体制的任务。智能化的测量控制设备在本文的设计中是基于是根据同步时钟技术来实现它的测量和控制的。基于时间同步的原理完成数据在多钟设备上的数字化信号的同步获取，并用统一化的模型来完成标准化的信息和时标同步的使用，最后从根源统一电网各级设备规则标准从而获的统一的，规范的基础信息。
[Abstract]:Smart grid is recognized as the most effective solution to the security, intelligence, environmental protection and other problems in the current power system. At the same time, smart substation is the core link and basic element of building a strong smart grid. The smart grid is based on unity and openness. In this paper, the advantages and disadvantages of traditional substation are analyzed in detail, and then the analogy analysis between traditional substation and intelligent substation shows that there is a huge difference between the structure and function realization. Furthermore, an intelligent substation reconstruction scheme based on traditional substation is put forward. The technical characteristics of the substation structure are also analyzed and its far-reaching significance to the future power grid is expounded. While keeping the existing basic framework unchanged, this paper designs a unified platform structure based on the existing substation, which can collect digital basic information. Through this structure, the information protocol is standardized, and the power grid system is more stable. The management is more uniform, time synchronization, etc. Finally, the task of expanding the whole power network information system is accomplished by the first level liaison. The intelligent measuring and controlling device is based on the synchronous clock technology in the design of this paper. Based on the principle of time synchronization, the synchronization of digital signals on multi-clock devices is completed, and the standardized information and time scale synchronization is realized by a unified model. Finally, unified and standardized basic information is obtained from the root of unifying the standards of equipment rules at all levels of the power grid.
