1. A load-frequency control system for a power system having steam and gas turbine-generator units, said control system comprising a plurality of gas turbine-generator units, means for controlling the load level of each of said gas turbine-generator units to satisfy a load reference applied thereto, means for generating the load references for the respective units to provide for a substantially constant system alternating frequency of predetermined value substantially without exceeding a high blocking limit for each of said units, means for generating a representation of turbine exhaust temperature and combustor shell pressure for each unit, and means for dynamically generating the high blocking limit for each of said units as a function of the turbine exhaust temperature and the combustor shell pressure.
