【摘要】：智能電網被公認為是解決當前電力系統(tǒng)在安全、智能、環(huán)保等多方面問題上最有效的方案，與此同時智能變電站是建設堅強智能電網的核心環(huán)節(jié)和基本要素。 智能電網的是以統(tǒng)一性和開放性為根本的。本文先具體分析了傳統(tǒng)變電站的優(yōu)勢和劣勢然后將傳統(tǒng)變電站和智能化的變電站進行類比分析得出，在結構的組成和功能實現上兩者之間有巨大差別，進而提出了以傳統(tǒng)變電站為基礎對一、二次設備的智能化的變電站建設改造方案，還對該變電站的結構的技術特點進行分析并闡述了它對未來電網的深遠意義。本文在保持現有基本構架不產生變化的同時，基于現有變電站設計出一種可以采集數字化的基本信息的統(tǒng)一化平臺結構，通過這種結構使信息協(xié)議標準化，電網系統(tǒng)更加穩(wěn)定，管理更加統(tǒng)一，，時間同步等，最后借由一級級的聯絡完成拓展整個電網信息體制的任務。智能化的測量控制設備在本文的設計中是基于是根據同步時鐘技術來實現它的測量和控制的�；跁r間同步的原理完成數據在多鐘設備上的數字化信號的同步獲取，并用統(tǒng)一化的模型來完成標準化的信息和時標同步的使用，最后從根源統(tǒng)一電網各級設備規(guī)則標準從而獲的統(tǒng)一的，規(guī)范的基礎信息。
[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.
