Abstract:
1. A gas turbine system with operating modes of a combustion system of a gas turbine system, the gas turbine system comprising: a compressor, the combustion system and a turbine; a fuel control system; a turbine control system employing a mode logic for controlling operational parameters of the gas turbine system from a startup operating mode through a base load operating mode, the turbine control system comprising a controller configured to transmit a fuel demand signal from the turbine control system to the fuel control system, the controller comprising: encoded information regarding combustion efficiency for each of the operating modes based on at least one reference parameter; a processor configured to calculate a starting combustion efficiency for a starting operating mode among the operating modes and an ending combustion efficiency for an ending operating mode among the operating modes based on the encoded information; and to determine a bias to the fuel demand signal for operation between the starting operating mode and the ending operating mode based on the starting combustion efficiency and the ending combustion efficiency.
