Digital computer control system and method for monitoring and controlling operation of industrial gas turbine apparatus employing expanded parametric control algorithm

摘要

A hybrid digital computer gas turbine power plant control system which may operate in a multiple control loop arrangement is provided with a plurality of process sensors at various operating cycle positions. Derivative inputs provide a basis for responsive control system variation of gas turbine parameters. Parametric control is maintained over generator and turbine subsystems during all modes of operations. More specifically, optimally arranged system thermocouples provide inputs from which temperature control variables are derived. Inlet guide vanes are positioned in response thereto to control exhaust gas temperatures while maintaining near optimum generator output.
