【 摘 要 】

Object and purpose of research. This paper investigates brake resistor units of frequency-controlled propulsion drives in marine electric propulsion systems. This unit absorbs propulsion energy in case of generative braking. The purpose of this research is to develop a calculation procedure for the parameters of resistors in this unit. Materials and methods. The study is based on scientific and technical information available in the literature about electric drive theory, as well as on as well as on personal findings and experience of the authors gained in nu- merous 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, including propulsion drives, in Simulink MATLAB software package. Main results. Development of engineering procedure that enables correct calculations and selection of electric equipment for brake resistor unit already at early stages of detailed design without the necessity of mockups for laboratory studies. Conclusion. Practical results obtained by the authors and applied in Simulink MATLAB software enable simulation of electromechanical processes taking into account non-linearity of their respective differential equations, which makes the procedure suggested by the authors accurate and handy.
