Experimental determination of dynamic modes of a synchronous generator excited by a solar panel

Relevance: the importance of the work lies in conducting the necessary studies of the modes of synchronous generators (SG) when providing their excitation systems with direct current from independent sources - solar panels. Providing excitation systems of synchronous generators with current from solar electric panels will save a significant amount of energy during SG operation. It is necessary to take into account the variability of solar energy affecting the SG modes and analyze the dynamics of various SG modes. Similar studies are carried out by scientists in many countries, as well as in our republic; their results are necessary to expand the use of solar energy in electricity generation. Aim: study and analysis of the modes of a synchronous generator when providing it with excitation current from a solar electric panel - an independent energy source. Methods: the theory of electrical machines and methods of comparative analysis of parameters during start-up and operation of a synchronous generator with a DC excitation source from a solar cell were used. Results: the starting and dynamic characteristics of a synchronous generator using direct voltage generated by a solar battery were studied; The parameters of excitation current and generated current under normal start and short circuit conditions were studied. Key words: synchronous generator, solar panel, excitation current, dynamic mode, current parameters, oscilloscope, short circuit current, measurement, graph, technical characteristics.
