Abstract
A characteristic evaluation device is for a gas turbine that includes a compressor, a combustor, and a turbine includes a processor. The processor calculates, in gas-turbine characteristics including characteristics of at least one of the compressor, the combustor, and the turbine, a correction value for correcting influence due to environmental conditions in which the gas turbine is placed based on operation data of the gas turbine. The processor also calculates the gas-turbine characteristics corrected based on the correction value, and evaluates the gas turbine by comparing the gas-turbine characteristics after correction with a predetermined reference value.
