摘要
本文以SDP9000型数字化变电站为例阐述了一种新型合并单元的硬件设计,并对其以太网通信方式进行了详细介绍。该设计采用DSP和FPGA相结合的方式,开发相应设备;采用百兆工业以太网通信技术,使得装置具有强大的数据传输能力;采用模块化设计思想,便于检修及系统升级,增加了系统的可靠性和灵活性。
This paper presents a new design scheme of the merging unit of SDP9000 digital substation. Ethernet communication of the merging unit was analyzed in detail .The smart terminal can separate the secondary equipment from the primary equipment and is the equipment in the Process level. It can make electromagnetic transformer and switcher digital. The paper describes the basis fear sot＇t- ware and hardware of the smart terminal. DSP＋FPGA is used as the kernel to develop the merging unit. It has the powerfut data processing ability by means of using 100M Industrial Ethernet communication technology. Using modular design method, this device improve the ability of maintenance and system upgrade and has the reliability and flexibility.
