<P>PROBLEM TO BE SOLVED: To provide mechanisms and techniques for remedying a blocked nozzle. <P>SOLUTION: System and method for controlling a stuck nozzle system installed between first and second turbines connected in series to a compressor are provided. The method includes: determining whether the nozzle system is stuck; instructing the first turbine to increase a minimum speed reference when the nozzle system is stuck; verifying whether the nozzle system continues to be stuck; instructing the compressor to increase an inlet bleed heat (IBH) flow from a current value to a maximum value when the nozzle system is stuck; verifying whether the nozzle system continues to be stuck; and instructing the compressor to increase an inlet guide vanes (IGV) angle from a current value to a maximum value when the nozzle system is stuck. <P>COPYRIGHT: (C)2012,JPO&INPIT |
