数字化变电站是建立在IEC61850通信规约基础上,由智能化一次设备(电子式互感器、智能化开关等)和网络化二次设备分层(过程层、间隔层、站控层)构建,能够实现变电站内智能电气设备间信息共享和互操作的现代化变电站。现就数字化变电站过程层关键设备的配置原则和选择方案,根据国内外高压电气设备和二次设备(IED)的发展情况和运行经验,提出了当前建设基于IEC61850数字化变电站的二次过渡方案。
The digital substation is based on the IEC61850 communication protocol and is constructed by intelligent primary devices (electronic transformers, intelligent switches, etc.) and networked secondary devices (process layer, bay layer and station control layer) and can be implemented Modern Substation for Information Sharing and Interoperability among Smart Electrical Equipment in Substation. Now on the configuration principle and selection scheme of the key equipment in the digital substation process layer, according to the development and operation experience of high voltage electrical equipment and secondary equipment (IED) at home and abroad, the second transition scheme based on IEC61850 digital substation is proposed.
