Software system for verification of gas fuel flow

Abstract

A computerized system for accurate, independent verification of natural gas fuel flow in order to control H2O injection flows. The H2O is injected into a combustion system to control emissions. The system comprises: receiving gas turbine control parameters from a gas turbine control system; receiving control parameters from a megawatt transducer; calculating values based upon readings from said control system and said megawatt transducer; comparing said values to a megawatt reference curve; detecting an abnormal reading; starting a timing sequence during which said reading is monitored; transferring NOx and H2O water injection control to a megawatt module at completion of said timing sequence; alerting operator said transfer; allowing for return of control to said gas turbine control system once said abnormal reading is corrected.
