According to the high-reliability requirement of emergency trip system (ETS) for steam turbine, a triple modular redundant ETS system is presented in detail in this paper. The system consists of groups of input modules gathering data from sensors, system bus, main controllers running the same application program, and groups of output modules, all of which are configured to triple hardware redundancy...
A triple module redundant turboset emergent trip system (ETS) based on triple modular redundancy fault-tolerance technology is discussed in this paper, which is used for safety protection of large steam turbine. The system consists of input modules, main controllers, bus controllers and output modules, in which the 2-out-of-3 (2oo3) vote mechanism is adopted to enhance the reliability and safety of...
