This article uses the Markov process to analyze the displacement redundant unit on the active magnetic bearings (AMB) system in HTR-10GT, especially on the aspects of the reliability, redundancy and maintenance issues. The reliability mathematical model is established, and the state transition diagram and the state transition matrix are deduced under the different conditions, furthermore the expression on reliability of the displacement redundant sensors is given. According to the different failure rate of single degree speed sensor, the curve about the measurement unit reliability versus time is calculated. The method mentioned above provides a new and practical approach to improve the reliability of the system and to optimize the displacement measurement redundant unit, which also can to be as a guiding role for the fault diagnosis of system.
