摘要： The present application provides a method of evaluating fatigue damage in a turbine by a data acquisition system. The method may include the steps of receiving a number of operating parameters from a number of sensors and based upon the operating parameters, determining: a run time from start-up until the turbine reaches X percent load and a start-up temperature transient from start-up until the turbine reaches X percent load, and calculating: a run time ratio of the determined run time until the turbine reaches X percent load to a predetermined run time, a start-up temperature ratio of the determined start-up temperature transient to a predetermined start-up temperature transient, and a fatigue severity factor by averaging the run time ratio and the start-up temperature ratio. Based upon the determined fatigue severity factor, altering one or more of the operating parameters and/or initiating repair procedures.

摘要： The present application provides a method of evaluating valve tightness in a turbine by a data acquisition system. The method may include the steps of receiving a number of operating parameters from a number of sensors, opening a first valve and closing a second valve, closing the first valve, determining a pressure decay time between the first valve and the second valve, determining a stable value of pressure between the first valve and the second valve, comparing the pressure decay time and the stable value of pressure to predetermined values, and altering one or more of the operating parameters and/or initiating repair procedures if the pressure decay time and/or the stable value of pressure is increasing and/or exceeds the predetermined values.
