Abstract

A control system for multiple gas turbine-generator units 12 comprises a local control computer 14 which computes a maximum permissible output for each gas turbine-generator unit independently as a dynamic function of combustor shell pressure and exhaust temperature in that unit and the output thus obtained is transmitted to a central control 16. Load demands calculated for each unit are dispatched from the central control to individual local control arrangements 18 which respond to control their respective gas turbine- generators in a manner not to exceed the respective maximum output. Each turbine control 14 sets its generator output at a preset level which is modified by load change signals from the central control 16 and each control 14 operates its turbine fuel control to satisfy the load demand. <IMAGE>
