Summary

 
Object and purpose of research. This paper studies electric drives of pod propulsion units installed at heavy-duty icebreakers of the new generations: their electric propulsion systems are based on synchronous motors and static frequency converters. The purpose of this work is to develop a flow chart and investigate electromechanical properties of vectorcontrolled synchronous propulsion drive that meets stringent requirements to the dynamics of electric propulsion systems aboard new-generation icebreakers.
Subject matter and methods.The study is based on the data available in theoretical literature on electric drives, as well as on personal findings and experience of the authors gained in numerous R&D projects on marine electric propulsion systems. The method followed by the authors is based on the possibility to simulate various electromechanical devices and systems in Simulink application and Sim Power Systems library of MATLAB software package
Main results. The main result of this study is the flow chart of propulsion drive based on 6.5MW synchronous motor: this system is not only as fast and accurate in terms of output coordinates as the best examples of DC and frequency-controlled AC drives, but excels them in terms of power efficiency.
Conclusion. Practical findings of the authors could be helpful in development of propulsion drives based on synchronous motors for electric propulsion system of advanced new-generation icebreakers.
