Variants of structures of the ship’s electromotive complex with common DC bus-bars

Schematic and algorithmic solutions for the design construction of ship’s electromotive systems various purposes are considered. The analysis existing structures complexes, as well types electrical converters used is carried out. structure an complex based on a transformerless with common DC bus-bars proposed. main goals improvement to increase energy efficiency, reliability survivability electric power plant, lower weight size characteristics. proposed allows braking propellers without using additional circuits redistribution between propeller machines dissipation in working medium - water. An algorithm mathematical modeling reverse modes installation Timing diagrams changes torque, rotation speed each motors presented. It shown that synthesized makes it possible reduce emissions pollutants into environment, save fuel within range 10÷15%, depending operating ship comparison systems.
