浅谈数字化变电站的技术与发展

Technology and Development of Digital Substation

基于变电站自动化系统的发展,数字化变电站技术在近年得到长足的进步。阐述了数字化变电站和传统变电站的特征区别,介绍了数字化变电站五个实现基础,即数据采集的稳定性、设备的互操作性、网络通信的可靠实时性、合并单元的冗余性、技术管理的适应性,并以现实运行的数字变电站为例分析了数字化变电站在数字化过程层、保护、数据采集共享、系统安全等方面的问题。通过分析可以认为,数字化变电站必然成为未来变电站的发展趋势,数字化电网也同样有很大的发展潜力。

With the development of substation automatization system,the digital substation technology has made a great progress in these years.This thesis mostly expatiated the difference between digital substation and traditional substation,and introduced five bases of digital substation,that are the stability of date collection,the mutual handle quality of equipment,the credibility and real time quality of network corresponding,the redundancy of incorporate unit,the adaptability of technique managing.Problems of digital substation are analyzed from different aspects,that are digital process layer,protection,the collection and share of date,and system security.Digital substation is inexorable trend of substation in the future,and also the digital grid has prodigious develop potential.
