System and method for accelerating and sequencing industrial gas turbine apparatus and gas turbine electric power plants preferably with a digital computer control system
First Claim
1. A gas turbine electric power plant comprising a gas turbine having compressor combustion and turbine elements, a generator coupled to said gas turbine for drive power, a fuel system for supplying fuel to said gas turbine combustion element, means for operating said fuel system to energize said turbine, electronic means for controlling said fuel system operating means including electronic means for generating a speed reference, and electronic means for controlling said operating means to control the fuel flow in response to the speed reference and actual turbine speed normally to accelerate said turbine to operating speed from a predetermined lower speed in a substantially fixed period of time irrespectively of the existing ambient temperature over an ambient temperature range at least from -40°
- F. to 120°

Abstract
A gas turbine power plant is provided with an industrial gas turbine which drives a rotating brushless exciter generator coupled to a power system through a breaker. One or more of the turbine-generator plants are operated by a hybrid digital computer control system during sequenced startup, synchronizing, load, and shutdown operations. The program system for the computer and external analog circuitry operate in a multiple gas turbine control loop arrangement. Logic macro instructions are employed in programming the computer for logic operations of the control system.
