Studies of the Operation of a Solar Power Plant

Resumo

This article paper the results of studying the effect of atmospheric climatic factors on the operation of the photovoltaic modules of a power plant. The modes of operation of the solar power plant were studied depending on temperature parameters, as well as taking into account the wind load and other parameters. The change in the production of electric energy is shown for various results of the study of a serial photovoltaic module RS 250 with a power of 250 W, which is used for the generation of electric energy at some solar power plants in the south of Ukraine. The results make it possible to evaluate its performance in natural conditions depending on various climatic factors. The article describes the study of the operation of a wind power plant (WPP) with helical blades; this type of WPP allows using the kinetic energy of the wind flow more fully to convert it into mechanical energy of rotation of the wind turbine shaft. The coefficient of wind energy utilization by the rotor of a wind turbine with such a design is much higher than that of horizontal-axis wind turbines. Wind–solar power plants operating in parallel with the general power grid occupy quite large territories. In this case, as a rule, wind turbines are located in the north part of the plant, without interfering with the operation of the modules, while photovoltaic modules are located on the south side of the wind turbines, which minimizes the losses from shading by the tower, engine room, and wind turbine blades. All the studies described above allow installing additional generating capacities on wind and solar power plants, which will greatly increase the total production of the plant and the efficiency of the entire energy complex.
