摘要
介绍了IEC60044-8和IEC61850中规定的电子式互感器数字输出接口的特性,并设计了一种基于以太网的通信模块以实现此功能。该方案采用基于单片机的嵌入式硬件平台,利用RTL8029AS实现以太网物理层和链路层的大部分功能,并采用TCP/IP协议进行数据传输和系统维护,具有设计简单、维护方便、传输速率快等优点,能够满足变电站自动化、网络化发展对电子式互感器的要求。
According to the requirement of standard IEC 60044-8 and IEC 61850, the digital output interface characteristic of electronic instrument transducers is introduced. A communication model between the merging unit and the secondary equipment based on Ethernet is designed for substation automation system. The model utilizes single-chip microcomputer as the embedded hardware platform, uses RTL8029AS to realize the main function of Ethernet physical layer and link layer, and adopts TCP/IP protocol to transmit data and maintain system. This scheme is simple and easy to maintenance, and has high transmission rate. It can satisfy with the requirements of substation automation and network to the electronic instrument transducers.
