| Abstract: | 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. |
