MAQOLA ANNOTATSIYASI

There are briefly analyzed the features of the use of a tracking system for the Sun for solar power installations and stations. There are considered methods, approaches and programs for calculating the optimal angle of inclination of photovoltaic arrays relative to the horizon for the regions of Uzbekistan. There was made a study of the influence of the angle of inclination of photovoltaic batteries (PVB) at a photovoltaic station (PVS) integrated with a low-voltage electrical network (0.4 kV) on the amount of electricity generation using the PV SYST.7.2 software package. Calculations to determine the optimal inclination angles of photovoltaic batteries (β0) were performed for the southern region (Termez), the northwestern part of the region (Muynak) and the northeastern part (Tashkent) at various PVB inclination angles β~180÷ 720. The optimal angles of inclination were determined for the stationary location of the PVB to generate the maximum electric power of the PVS during the year. Based on the simulation results, the optimal values of PVS electricity generation are determined taking into account (β0) and the differences in PVS electricity generation due to different values of (β0) and geographic latitudes (βс.ш0 ) for the regions (Termez, β~310, Еβ ~16036 kWh, ∆ЕPVS=55 kWh ), (Muynak, β~320, Еβ ~14789 kWh, ∆ЕPVS=66 kWh ) and (Tashkent, β~330, Еβ ~15360 kWh , ∆ЕФЭС=121 kWh ). The difference in electricity losses before it is supplied to the low-voltage network in those regions is insignificant and amounts to 2.2÷2.3% in comparison with the amount of energy produced by the PVS itself.
