    摘要： A computer-readable medium including computer-executable instructions that, when executed by a processor, cause the processor to perform acts, via an associated method that includes selecting a fault tree based upon an architecture of a safety instrumented system. The method includes evaluating at least a failure probability due to dangerous detected failures and a failure probability due to dangerous undetected failures as a function of values of factors. A portion of the failure probability due to dangerous undetected failures is based on failures detected during proof testing and a remainder of the failure probability due to dangerous undetected failures is based on failures detected during refurbishment. The method includes generating a probability of failure on demand for the safety instrumented system by combining at least the failure probability due to dangerous detected failures and the failure probability due to dangerous undetected failures according to the fault tree.

    摘要： A method of monitoring a power generation system that includes a steam turbine that is coupled to a gas turbine engine. The method includes calculating, by a control system, a gas turbine engine power output that is based at least in part on a predefined power generation system power output and a predefined steam turbine power output. The power generation system is operated to generate a power output that is approximately equal to the predefined power generation system power output. A signal indicative of a sensed operating power output of the gas turbine engine is transmitted from a sensor to the control system. A condition of the steam turbine is determined based at least in part on the sensed operating gas turbine engine power output and the calculated gas turbine engine power output.

    摘要： A system to monitor the health of the structure, program product, and associated methods are provided. The system can include multiple health monitoring sensor nodes positioned to monitor parameters of a portion of the body of the structure. Sensor elements of the sensor nodes are spatially positioned along the body of structure at related or complementary locations to form a special correlative relationship between sensor nodes. The system can also include a data collector having a transceiver positioned to gather sensed parameter data from each of the sensor nodes, and a central computer including in memory, parameter process program product adapted to analyze the sensed parameter data, correlate the sensed parameter data to infer a state of health of the structure responsive to the correlation, and to detect or otherwise determine a type, severity, and/or location of damage to or incipient failure of the structure.
