| 摘要: |
| 电子式电流互感器ECT（Electronic Current Transformer）与电子式电压互感器EVT（Electronic Voltage Transformer）组成的合并单元和间隔层中保护、测量等设备的连接是实现变电站自动化系统中过程层与间隔层串行通信中重要的一环。从IEC61850标准出发，基于采样值传输模型对电子式电压互感器模型从逻辑设备、逻辑节点和数据对象三个方面进行了具体的合理构建，并通过特定服务实现此模型在通信栈协议上的映射。通过此模型及其映射，我们明确了变电站自动化系统中电子式互感器和其他设备间的信息交互和数据传输的要求。电子式互感器作为一种新型的互感器，其应用将对变电站自动化系统产生深远的影响。 |

| Abstract: |
| The merging unit consists of Electronic Current Transformer(ECT) and Electronic Voltage Transformer(EVT).The conjuction of merging unit and bay level are the key elements in realizing serial communication between the process level and bay level of the substation automation system.According to the sample value model,the EVT model is constructed in a specific and rational way from Logic Device(LD),Logic Node(LN) and Data Object,with the communication stack service mapping of this model implemented by Specific Communication Service Mapping(SCSM).It is acknowleged that the demand of ecchange information and transmit datas in subsation automation system by EVT model.Be a kind of new transformer,its application in SAS will have a promising future since its theoretical and practical advantage. |
