基于IEC61850的嵌入式智能通信接口设计

Design of Embedded Intelligent Communication Interface Based on IEC61850

针对互感器对多个不同装置的同一信号作复杂的二次接线,研究设计了一种满足数字化变电站要求的新型信息采集与发送通信接口。该设计遵循IEC61850规约,采用嵌入式技术,借助32位嵌入式微控制芯片和嵌入式实时操作系统,对一次设备进行数据采集和状态信息汇集。经处理后可形成满足IEC61850规约要求的数字信息,并能以标准的以太网方式对相关的数据进行传输,有利于资源共享与控制操作。

Aimed at the complexity of second wiring connection for the same signal come from lots of different devices, the paper designed a sort of data acquisition and communication interface which met the need of digital substation.The design followed the protocol of IEC61850,and applied the embedded technology,by means of 32-bit embedded micro-controller chip and embedded real-time operating system, to carry through data acquisition and state information collecting.After the information being processed, it could form digital information met by the protocol of IEC61850, and transmit the related data in Ethernet mode of standard, and it is propitious to resource sharing and operation controlling.
