EN The article describes issues related to power distribution between a power plant system consisting of a synchronous generator operating at variable shaft speed and a super capacitor which is a short-term source of electricity for sudden electrical load changes. In the presented system a generator and a battery of supercapacitors were connected with use of power electronic converters. The synchronous generator is connected to the DC network via an AC-DC converter and the super capacitor is connected with means of an isolated DC-DC converter. Both converters have been equipped with auctioneering diodes to prevent the flow of equalizing currents. The theoretical basis and results of experimental research obtained on a laboratory test-stand equipped with the aforementioned system are presented.
