The purpose is to development, optimization of design and circuit solutions of autonomous heat and electric power plant. Research methods are a comprehensive theoretical and experimental analysis of the impact of design and technological solutions of the components of the thermal power plant on its initial photovoltaic, thermal and electrical characteristics and parameters. Basic scientific and technical results: The design and sketch design documentation have been developed and a solar concentrator has been manufactured, which is a circular array of segments made of mirror material, the integrated reflection coefficient of which reaches 95%, and the predicted concentration factor is more than 400. Experimental studies of the influence of the level of solar radiation intensity on the initial parameters and light-diode characteristics of solar cells based on the CdS/CdTe heterosystem were carried out and the presence of the maximum on the dependence of efficiency on illumination was established. It is established that the main factor that leads to a decrease in the filling factor of the light I - V curve is a decrease in shunt resistance. Depending on the illumination of all other diode parameters, it can be assumed that in the solution of the problem with decreasing shunt resistance, it can be expected that the tendency to increase efficiency with increasing illumination can be continued in the region of concentrated radiation. The design of the radiator of the heat exchange unit with "micro-channels" is proposed, calculations and simulations of temperature modes of which have shown that it allows dissipating thermal energy at peak moments of solar radiation and providing the necessary cooling mode of SC. Preliminary design documentation has been developed and a heat exchange unit with " Product Description popup.authors Dobrozhan Andrii I Zaitsev Roman V Kirichenko Mihail V Meriuts Andrii V Nikitin Viktor O Harchenko Mykola M Khrypunov Gennadiy S Khrypunov Maxim H popup.nrat_date 2022-03-09 Close
