一种新型合并单元的设计与研究

Design and Research of a New Merging Unit

在广东电网,数字化变电站技术已得到了逐步应用,数字化变电站应用数量逐渐增多。考虑到变电站数据量大,且需要对时准确等要求,其数字化接口作用的合并单元十分重要。文章针对合并单元实时性强、数据通信速度快等特点,设计了一种新型合并单元,该单元由FPGA与ARM组成,具有同时处理多任务、通信速率快等特点,适用于新型数字化变电站。

In Guangdong Power Grid, digital substation technology has been gradually applied, the number of digital substation applications is gradually increasing. Considering the large amount of data in substation and the requirement of timing and accuracy, it is very important to combine the function of digital interface. In this paper, a new merging unit is designed, which is composed of FPGA and ARM, and has the characteristics of multi-task processing and fast communication rate. It is suitable for new digital sub-station.
