Abstract
Certain embodiments of the invention may include systems, methods, and apparatus for determining steady state conditions in a gas turbine. According to an example embodiment of the invention, a method for determining stability in a gas turbine is provided. The method can include receiving a guide vane (VGV) command and a fuel stroke reference (FSR) command associated with a gas turbine control system, determining a filtered VGV change based at least in part on the received VGV command, determining a filtered FSR change based at least in part on the received FSR command, and outputting a unit stability signal after a pickup delay time when the filtered VGV change is less than a predetermined VGV stability threshold and the filtered FSR change is less than a predetermined FSR stability threshold.
