ABSTRACT:
Method and apparatus for generating an ignition enabling signal for use with a given combustion turbine having an ignition system which ignites the turbine in response to an enabling signal, wherein a turbine speed signal is given, is shown to include a sensor for generating an ambient air temperature signal, a reference member for generating a reference signal representative of the turbine speed at which optimum air flow exists for ignition, a comparator for comparing the reference signal to an adjusted speed signal and for generating the ignition enabling signal when the adjusted speed signal exceeds the reference signal and for providing the enabling signal to the ignition system. The adjusted speed signal is generated by modifying the turbine speed signal in response to the ambient air temperature signal. Such modification is achieved by summing the turbine speed signal with a bias speed factor. The bias speed factor is representative of the difference between optimum turbine ignition speed and that turbine speed necessary for optimum ignition air flow to exist in said combustion turbine at such ambient temperature.
