One of the perspective directions of development of modern shipbuilding is the creation concept of «full electric ship» (FES). In turn implementation of this concept is impossible without creation of a modern power kernel of FES – the integrated electrical power system (IEPS), including electric propulsion systems (EPS). Necessary stages of design and safe operation of structurally difficult systems of FES-level are system calculations and mathematical modeling on the basis of which results full-scale design is carried out and skilled and deliverable samples are created. Special requirements are imposed to a choice and development of management algorithms by rowing electric drives (RED). In particular, the system of automatic control synchronous RED of ice class vessels must to provide constancy of the frequency rotation modes, constancy of power and constancy of the electromagnetic moment of synchronous rowing electric motors (REM). The mathematical description and results of computer modeling of operating modes of the IEPS ship machine and valve complexes consists of the main generating units, power semiconductor converters, REM and propeller steering complexes are provided in article.
