DISCUSSION ABOUT APPLICATION OF OPTICAL-ELECTRIC TRANSDUCER TO SUBSTATION COMMUNICATION & CONTROL SYSTEM

As a novel method for measuring the current and voltage in power system,Optical-Electric Transducer (OET) is becoming a hot spot in substation automation system (SAS),especially about its application in practice.This paper analyzed the characteristic of OET and discussed the effect of its application to communication system in substation.It indicated that the main effects were about the ways of communication and system architecture of communication.According to the situation of SAS in China,it also emphasized how to apply OET in SAS and described the steps to fulfill it:The interface between OET and Substation Communication System can be realized through Instrument Transducer Unit.And with the development of communication technology and application requirement of SAS,there are three different kind of access mode during the application of OET in SAS.Being a new type of electronic transformer,its application in SAS will have a promising future since its theoretical and practical advantage.
