IEC61850在含微电网的配电网中的应用探讨

Discussion on Application of IEC61850 to Distribution Grid with Micro-grid

微电网作为智能配电网的有机组成部分,具有灵活高效利用新能源的优点,IEC61850通信使得不同制造商制造的电力设备在一个系统中能实现互操作.本文根据IEC61850通信标准数字化变电站被分为变电站层、间隔层及过程层,分析了数字化变电站通信系统的3层结构及含微电网的智能配电网通信结构,研究了含微电网的智能配电网在故障时的信息交互,并对馈线终端单元(FTU)进行信息建模,探讨了IEC61850通信在含微电网的智能配电网中的应用.

The micro-grid is an integral part of intelligent distribution networks with its advantages of flexible and efficient use of new energy, IEC 61850 communication makes it possible that the electrical equipments of different manufacturers can interoperate in one system. In this paper, digital substation is divided into substa- tion layer, interval layer and process layer based on the IEC61850 communication. This paper analyzes the three-layered structure of the digital substation communication systems and the communication structure of intelligent distribution grid containing micro-gird; explores the information exchange when there are faults in the grid and the feeder terminal unit（FTU）for information modeling; discusses the application of IEC61850 communication to intelligent distribution grid with multi-micro-grid.
