FIELD: engines and pumps.
SUBSTANCE: invention is related to power engineering. System is suggested for generation of electric energy with drive from multi-circuit gas turbine engine, which includes at least the first and second cascades. The first cascade comprises turbine and compressor installed on the first shaft, the second cascade has at least turbine, which is installed on the second shaft and is not mechanically connected to the first shaft. The main generator is connected to one of cascades, and auxiliary generator-engine is also connected to one of cascades. In order to control operation of engine, every generator frequency control is applied. Auxiliary generator-engine may work either in generation mode, bleeding energy from its cascade, or in engine mode, sending energy to its cascade.
EFFECT: provides for optimisation of engine efficiency factor by means of air control via engine so that air mixture components ratio is controlled, which helps to maintain high peak temperature sent to working fluid medium in engine.
