Title:
PERFORMANCE DIAGNOSTIC METHOD OF GAS TURBINE, AND DIAGNOSTIC DEVICE OF GAS TURBINE
Document Type and Number:
Japanese Patent JP2019214981
Kind Code:
A
Abstract:
To provide a performance diagnostic method of a gas turbine and a diagnostic device of the gas turbine, capable of diagnosing the performance degradation of the gas turbine during operation.SOLUTION: A performance diagnostic method of a gas turbine includes a first process ST12 for executing a performance test of total load of a reference gas turbine, a second process ST13 for acquiring a turbine expansion ratio and a mass flow rate of the reference gas turbine from a measured value and numerical value hydrodynamics analysis based on the measured value, a third process ST14 for executing a performance test of a diagnostic object gas turbine and acquiring a turbine expansion ratio and a mass flow rate, and a fourth process ST15 for diagnosing the performance of the diagnostic object gas turbine by comparing the turbine expansion ratio and the mass flow rate of the reference gas turbine with the turbine expansion ratio and the mass flow rate of the diagnostic object gas turbine.SELECTED DRAWING: Figure 3
