基于IEC 61850的配网自动化通信技术研究

Communication technology for distribution automation based on IEC 61850

为了减少配电终端接入配网自动化的调试和维护工作量,在IEC 61850的基础上建立了一种开放式的、支持即插即用的配网自动化通信体系。首先分析了IEC 61850已有逻辑节点在配网自动化中的应用,并以柱上开关馈线自动化终端(FTU)为例,建立了配电终端的设备模型。在分析了IE C61850已有映射方式的基础上,提出了一种适合配网自动化的映射方式(Web Services+IEC 60870-5-104),采用Web Services传输信息模型数据,采用IEC 60870-5-104传输实时数据。通过样机系统,在实验室内验证了所提出的通信体系的可行性。

To reduce the debugging and maintenance work of a large number of field automation terminal units accessing to distribution automation, an open, plug and play terminal unit supporting communication architecture is proposed. The use of IEC 61850 logical nodes to distribution automation is analyzed. As an example, the device information model of pole-mounted feeder terminal unit （FTU） is established. A new mapping profile （Web Services ＋ IEC 60870-5-104） suitable for distribution automation is proposed. In this mapping profile, Web Services is used for information model exchanging and IEC 60870-5-104 is used for real-time data transferring. A prototype system is developed. The system demonstrates that the seamless communication supporting plug and olav between the master station and FTU can be realized using the proposed modeling and mapping methods.
