摘要
在电力系统自动化领域 ,特别在变电站自动化系统中 ,现场总线技术的应用已成为一种发展趋势。针对PROFIBUS现场总线产品最近在国内的应用情况 ,从讨论其存取协议着手 ,分析了其在自动化系统应用中信息传输的实时性和可靠性问题 ,指出了信息传输实时性与系统规模成反比的特性 ,得出了PROFIBUS现场总线更适合小型自动化系统应用的结论。
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.
