А CONCEPT FOR NEW TOPOLOGY ОF ELECTCI POWER SUPPLY SYSTEMS OF PORTS AND SHIPBUILING YARDS WITH SHORE POWER SYSTEMS AND RENEWABLE ENERGY SOURCES
Valentin Gyurov, Ginka Ivanova, Yuliyan Yordanov, Milen Duganov
The power supply systems of ports and shipyards are characterized by combinations of radial, main and radial-main schemes at different voltage levels - low, medium and in some cases high voltage. They typically one main high or medium voltage step-down and/or distribution substation, and multiple medium and low voltage substations. The existing power supply systems are designed and implemented in traditional ways, corresponding to the concepts and technical means of the second half of the 20th century. The implementation of the new technical means s the performance of new research on the optimization of existing ones or the development of fully technical solutions for power supply systems of ports and shipyards. The report presents a study adapted to a typical site - a shipbuilding enterprise in the city of Varna, and the results can be considered as a conceptual concept, evaluated with a corresponding technical-economic analysis. The results can serve in the realization of future investment intentions in ports, shipbuilding enterprises and enterprises from the port infrastructure.
