Research of MBC based on fieldbus and intelligent instrument

摘要

The automatization in power plat will enter the era of Digitalization and Information from that of Distributed Control System (DCS) and Network with the realization of enterprise informatization as measure and improvement of enterprise profit as the destination. Maintenance Based on Condition (MBC) is analyzed to be more rational than the traditional MBC, which can reduce the maintenance cost, prolong the life of device and improve the reliability and available rate of the unit. The intelligent instrument based on fieldbus is also discussed to be more intellectualized than the traditional one, such as self-calibration, self-compensation, self-validation, etc, which has more powerful function and can provide more accurate and sufficient information and data that can reflect the state of process and instrument itself. The MBC based on fieldbus and intelligent instrument represents the tendency of MBC in power plant.
