Design PV substation and study its impact on both side (33k and 11k) of 10 MVA station

Abstract

The Evaluation and improvement of electric substations, feeders and distribution network performance in the electrical systems leads to increased reliability in the service; it also leads to high financial return that encourages investment in this field. Studies show that 30% to 40% of the investment in the electricity sector is spent on substation distribution system. This project will work on analyzing and evaluate the Beit Hanina substation (10 MW, 33/11 kV) from different sides; Station capacity, old cables, power factor, load distribution. On the other hand, in order to build a solar power plant and connect it to a level of 33 kV or 11 kV, the Homer Pro program was used to collect information about the total number of panels, the method of their connection, the capacity of each panel, the total capacity, as well as information about the inverter in terms of the internal voltageand the external effort, efficiency, as well as the cables connecting betweenthe panels and the inverter and between the inverter and the main bass line.Homer program was also used to obtain the rate of solar radiation and the rate of heat in the spatial scale of Beit Hanina. Based on all the information obtained through the programs, a new 2 MW solar power plant was belt which is separated to two main stations with
