The influence of measurement inaccuracies on the assessment of the state of gas turbines in diagnostic systems

Wojciech Kosman


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.
