基于FPGA的微机保护图形化编程设计

Application of FPGA graphic oriented programming in protective relay

介绍了FPGA等大规模可编程逻辑器件的特点;针对现有微机保护产品开发手段的不足,提出并分析了采用FPGA实现低技术门槛、低成本、高可靠性微机保护图形化编程设计的方法,并陈述了图形化编程的具体实现过程;此方法与CPU基本无关,适用于各档次CPU图形化编程保护产品的设计开发。

This paper introduces the feature of FPGA or other VLSI Programmable Logic Devices. Aiming at the shortage of the existing protective relay developing means,it proposes and analyes a method of adopting FPGA to realize the low technique threshold, low cost, and high dependability graphic oriented programming design in protective relay. A practical implementation method of graphic oriented programming in protective relay is presented. This method hardly depends on CPU, thus can be used in graphic oriented programming design of CPUs in a flexible scope functions.
