The invention detects gas turbine bleed valve position discordances. The invention derives a modified exhaust gas temperature derivative as the predictive criteria in conjunction with a control logic to determine bleed valve position discordances that may indicate a mechanical failure in a valve, or in the control means for a valve.
What is claimed is: 1. A bleed valve position discordance system for a gas turbine comprising: an input configured to accept exhaust gas temperature data from at least one exhaust gas temperature element; a processor configured to receive the exhaust gas temperature data and output a modified exhaust gas temperature velocity; a comparator having an input for receiving the modified exhaust gas temperature velocity and an output coupled to a time delay, the time delay having an output; and a logic and gate having a first input coupled to the time delay ou...
