摘要
IEC 61850标准规定智能变电站的通信功能用以太网技术实现,因此其工作性能对智能变电站至关重要。本文对智能变电站网络通信的性能进行研究,主要内容从实时性、可靠性和同步性展开。详细分析这三方面的研究现状和存在的问题,提出了相应的改进措施。在实时性方面,提出用无源光纤以太网(EPON)或实时以太网技术改进通信的实时性,指出其应用潜在的困难。对于可靠性和同步性,比较了现存的各种技术,指出各种现存技术的优缺点,作为研究和应用的参考。
Ethernet is specified as the communication tool of smart subsation in IEC 61850 standard. Its performance is very vital to smart substation. This paper study the timeliness,reliability and synchronism of communication network in smart substation. The situation of the filed and existing problems are analysed,and some improvement measures is proposed. In consideration of timeliness,EPON and real-time Ethernet are introduced as well as its potential factors in application. As to reliability and synchronism,a variety of exiting technologies are compared,and some related merits and weakness are pointed out. It can be viewed as the reference of future application.
