ADAPTIVE MODEL-BASED METHOD TO QUANTIFY DEGRADATION OF A POWER GENERATION SYSTEM

摘要

A system includes a power generation system (10) and a controller (18) that controls the power generation system (10). The controller (18) includes a processor that generates a model (40) of the power generation system (10) that estimates a value (44,48) for a first parameter (44,46) of the power generation system (10). The processor also receives a measured value of the first parameter (44,46). The processor further adjusts a correction factor (52) of the model (40) such that the estimated value (44,48) of the first parameter (44,46) output by the model (40) is approximately equal to the measured value of the first parameter (44,46). The processor also generates a transfer function (86,88,90,126,128,130) that represents the correction factor (52) as a function of a second parameter (42) of the power generation system (10). The processor further displays the transfer function (86,88,90,126,128,130) along with one or more previously generated transfer functions (86,88,90,126,128,130) to quantify degradation of the power generation system (10).
