Improving the quality of the power supply system of technical fleet vessels when supplied from shore regional electric power systems

A significant increase in the load on technical fleet objects, such as floating cranes, dredgers, dredgers, etc., causes the problem of electromagnetic compatibility. Electricity supply of technical fleet vessels is carried out from 0.4 kV shore networks for economic reasons, but the quality of electricity of the shore-to-ship power transmission does not meet the requirements of GOST 32144-2013 and the Rules for the Classification and Construction of Inland Navigation Vessels of the Russian River Register (RSRR). Physical wear and tear of technical fleet vessels exacerbates this problem. Subject of the study: processes affecting the stability of the electrical load on the voltage of the ship's 0.4 kV network when supplying the vessel with electricity from a 10 kV shore network and violating the EMC of technical equipment. Objective of the study: development of scientific provisions and recommendations to improve the stability of ship voltage load nodes when powered from shore networks. Research subject: power supply systems of technical fleet vessels when powered from shore power systems. Research results: based on the conducted research, it is shown that the proposed method increases the stability of the electrical load on the voltage of technical fleet vessels when powered from shore networks, which is essential for water transport.
