A gas turbine power plant is provided with an industrial gas turbine which drives a generator coupled to a power system through a breaker. The turbine-generator plant is operated by a hybrid control system having digital function capability during sequenced startup, synchronizing, load buildup and steady state load, and shutdown operations. The control system also contains monitoring and protective subsystems which function through all stages of operation, with redundancy and permissive features which maximize turbine availability.

A gar turbine electric power plant comprising: a. a gas turbine having compressor, combustion and turbine elements; b. a generator coupled to said gas turbine for drive power; c. a generator breaker for coupling said generator to a power system; d. a fuel system for supplying fuel to said gas turbine combustion element; e. means for operating said fuel system so as to control said supplied fuel; and f. a control system which produces a control signal for controlling said fuel system operating means, including means for automatically changing said control signal at generator breaker closing to provide for an immediate pickup of load by said generator wherein said automatic changing means produces a control signal having a step change at generator breaker dosing, and said step change causes a step change in said supplied fuel said control system further including a plurality of control paths, said control paths including at least a speed control path for generating a speed control signal and a load control path for generating a load control signal, and means for selecting said control signal from among said control path signals wherein said speed control path is adapted to start speed signal rising before generator breaker closing, said load control path is adapted to start said load signal rising upon generator breaker closing at a level substantially the same as said speed signal at such closing, and said load signal increases at a slower rate than said speed signal after generator breaker closing, such that said speed signal normally is the selected control signal before generator breaker closing and said load signal normally is the selected control signal only after generator breaker closing.
