Discussion on application of PROFIBUS in substation automation

Han Yu

Abstract

The Fieldbus technology is extensively applied in power system automation, especially in substation automation system. According to the recent application of PROFIBUS products in China, the real time ability and reliability of information transmission in substation automation system are discussed on the basis of access control protocol of PROFIBUS. It is pointed out that the real time ability is opposite to system scale and the PROFIBUS is applicable to small scale substation automation system.
