PHOTOVOLTAIC DEVICE FOR THE NEEDS OF DRUZBA POWER STATION
Hristina Spiridonova The rectifier stations are the main unit of the power supply system of the metropolitan electric transport. They convert the three-phase voltage supplied by the electricity distribution company into the direct voltage needed to power the trams, trolleybuses and electric buses. Currently, 24 TICs are working for the needs of electric transport in the city of Sofia. They are constantly developing, updating and modernizing.
One of the areas of development of the TIS equipment is equipping them with photovoltaic systems that generate direct current energy based on the photovoltaic effect and feed it directly into the direct current supply network of the metropolitan electric transport. Among these TIS is the ”Druzhba” TIS, with a power of 3000 W, which came into operation in 1986. This report examines a photovoltaic device used for generating, controlling and supplying photovoltaic energy in the direct current network of metropolitan electric transport. Not to disrupt the normal operation of the rectifier station and not to change its nominal parameters. The considered equipment and principle of operation of TIS ”Druzhba” can be used in the educational process in the training of electrical engineers. photovoltaic system arrester photovoltaic panels monitoringHristina Spiridonova BIBLIOGRAPHY [1] Minev E.
