随着近年来高科技的不断发展,变电站向着数字化方向发展。数字化变电站也得到了业界人士的广泛重视,数字化变电站在传统的IEC61850通信规约的基础上,发展为智能化一次设备和网络化二次设备分层共同组建,实现了变电站设备间信息共享和互操作的现代化变电站,本文根据国内外变电站的发展和运行情况,简单介绍了基于IEC61850数字化变电站的电气二次设计的过度方案。 With the continuous development of high technology in recent years, the substation has been developing towards digitization. Digital substation has also been widely regarded by the industry, digital substation in the traditional IEC61850 communication protocol based on the development of intelligent primary equipment and networked secondary equipment layered jointly formed to achieve the substation equipment information sharing and interoperability Based on the development and operation of substations at home and abroad, this paper briefly introduces the over-scheme of electrical secondary design based on IEC61850 digital substation.
