要約(英語): The IEC 61850 based process bus system on a substation automation system is currently being verified in the world. Some typical IEC 61850 based process bus system contains “Sampled value” communication function and it requires the high accuracy time synchronization scheme to get sampling timing simultaneity in each merging unit. Authors surveyed the way of improving the process bus system, and focused to renovate availability of the time synchronization scheme for getting sampling timing that often used IEC 61588 “Precision Clock Synchronization Protocol” complied special network communication equipment and technics. This paper introduces a new process bus scheme using over sampling technology and new communication network using high reliable optical fiber splitter to as the renovation way. This paper also describes an example of verification test result to confirm the usability, e. g. the AC electricity measurement test to survey accuracy and current differential protection relay test to survey the real-time characteristic. Finally, this paper concludes the availability of this process bus system concept.
