47,376 SYSTEM FOR PROVIDING LOAD-FREQUENCY CONTROL THROUGH PREDICTIVELY AND DYNAMICALLY DISPATCHED GAS TURBINE-GENERATOR UNITS ABSTRACT OF THE DISCLOSURE An optimized high load blocking limit is indepen- dently computer calculated for each gas turbine-generator unit as a dynamic function of combustor shell pressure and exhaust temperature every second. A low load blocking limit can be calculated as a function of the high blocking limit. The high and low dynamic limits then define a band of mega- watts instantaneously available to the system. At the dispatch computer, load-frequency control is executed and the calculated load demands are dispatched to the various gas turbine-generator units which respond without exceeding the respective high and low load blocking limits. A turbine control unit load reference is modified by the dispatched load change and each unit load control operates its turbine fuel control valves to satisfy the load demand.
