Jiyan Zou · Dianli xitong zidonghua · 2005
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.
