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.

Analysis method for measurement error of operating parameters of gas turbine and control apparatus

A drainage system includes at least one inflow pipe, a first outflow pipe, and a pressure vessel connected to the inflow pipe and the first outflow pipe separately. A throttle orifice plate and at least one switching valve are connected in series on each inflow pipe, and a throttle orifice plate and at least one switching valve are connected in series on the outflow pipe. The drainage system further includes a pressure release device, a check valve is also connected in series on each said inflow pipe, and a pressure measurement device is also connected to the pressure vessel. The pressure release device is an automatic pressure control valve connected to the pressure vessel. The drainage system for a gas turbine can remove condensate during operation of the gas turbine, thereby ensuring safe operation.
