数字化变电站作为变电站自动化技术的发展方向,就目前技术发展现状而言,数字化变电站是由智能化开关、电子式互感器等智能化的一次设备和网络化的二次设备分层(过程层、间隔层和站控层)构建,建立在IEC 61850通信规范基础上,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。城市轨道交通供电系统通常由110 k V主变电所、中压供电环网、沿线设置的牵引变电所和降压变电所以及
Digital substation as the substation automation technology development direction, the current status of technology development, digital substation is by intelligent switches, electronic transformers and other intelligent primary equipment and network of secondary equipment layer (process layer, the interval Layer and station control layer) built on the basis of the IEC 61850 communication specification to enable the modernization of substations for information sharing and interoperability among smart electrical devices in substations. Urban rail transit power supply system is usually composed of 110 k V main transformer substation, medium voltage power supply ring network, traction substation along the line and step-down transformer substation, and
