The systems that monitor the performance of power generating units do so on the basis of measurements made during the operation of machines and devices. Every measurement inaccuracy influences the results of the performance assessment. The paper describes a comparison between the inaccuracies of the measurements taken in various sections of gas turbines and their influence on the calculations of chosen performance indices. The analysis is shown for a monitoring system that applies mass and energy balances of a gas turbine in the on-line mode.
