摘要： A fuel supply line system used for a gas turbine, including: fuel gas control valves used for controlling delivery to the gas turbine; a first line used for connecting the fuel gas source to the control valves; a second line used for connecting the control valves to the gas turbine; a monitoring device, configured to be used for determining the pressure inside the pipe at the outlet of the second line near said control valve; and a controller, configured to reduce the effective flow area of the pressure control valves or close the control valves when the determined pressure inside the pipe of the second line is greater than a predetermined pressure.

摘要： An analysis method is disclosed for detecting a measurement error of operating parameters of a gas turbine. An embodiment of the method includes: obtaining multiple measured values of the operating parameters, the operating parameters being at least part of the variables of multiple functions, each of the functions including analysis ranges; putting the measured values of the operating parameters into the functions whose variables include the operating parameters to calculate the results of the functions; comparing the calculated results of the functions with the analysis ranges of the corresponding functions; identifying one or more measured values of operating parameters who are at least part of the variables of the functions whose calculated results fail to fall within the analysis ranges of the corresponding functions; and determining a measured value of an operating parameter including the highest likelihood of a measurement error.
