a control system including a computing device in electronic communication with each sensor of the plurality sensors, wherein the computing device is configured to;
receive the signals from the sensors;
track the operating parameters indicated by the received signals over time;
apply the tracked operating parameters to a physics-based hardware lifing model; and
predict remaining hardware life for one or more components of the gas turbine based on the hardware lifing model; and
the control system is configured to adjust one or more operation settings of the gas turbine based on the predicted remaining hardware life to optimize the remaining hardware life.

Abstract
A system and a method for predicting and optimizing remaining hardware life of gas turbine components. Operating parameters of the gas turbine which may impact remaining hardware life are sensed and tracked using a plurality of sensors in communication with a control system including a computing device. Remaining hardware life is predicted using a physics-based hardware lifing model. The hardware lifing model may include an output of a filtration model configured to monitor contaminants based on a pressure drop across a filter. Optimizing the remaining hardware life is achieved by the control system adjusting one or more operation settings of the gas turbine.
