摘要
通过对光纤纵差保护装置及其光纤数字接口特点的分析，阐述了采用大规模可编程逻辑技术进行光纤数字接口设计可以提高通信的可靠性。具体分析了运用大规模可编程技术进行光纤数字接口设计的实现逻辑。该方法已成功应用于具体光纤纵差保护装置，具有硬件结构简单、配置灵活、通道时延小等优点。目前已在多处变电站投入运行，运行状况良好，光纤通信正常可靠。
Based on an analysis of the fiber-optical current differential protection and its fiber-optical digital interface,it isshown that the communication performance and reliability can be improved by using a programmable logic device in the designof fiber-optical digital circuit.Moreover,the hardware and the logic realization using PLD for the fiber-optical digital circuit aredetailed.This method is supported by its successful application in an actual relay for the simple hardware,flexibleconfiguration,and low communication delay involved.So far the relay has been satisfactorily operating in a number ofsubstations with stable fiber-optical communication performance.
