Object and purpose of research. The object of this work is automated frequency-regulated electric propulsion drive being a part of the electric propulsion system of the multi-purpose nuclear icebreaker currently under construction. The purpose of this work is to develop the functional chart of electric drive control that must be based on the vector control algorithm that would make it possible to implement the totality of tough requirements stated to the dynamics of electric propulsion drive. Materials and methods. This paper is based on scientific & technical information available in the publications dedicated to electric drive theory, as well as on personal findings and multi-year experience accumulated by the authors during R&D projects on development of marine electric propulsion systems. To accomplish their task, the authors were relying on the methods of designing a frequency-regulated electric propulsion drive as a closed automatic regulation system with several control channels, each of these channels, in its turn, consisting of several circuits synthesized as per the principles of successive correction. Main results. The main result obtained in the work on this paper is development of the control system for frequency-regulated electric propulsion drive based on asynchronous motor with 20 MW squirrel-cage rotor that equals the best Russian and foreign electric drives in terms of response speed and accuracy of maintaining specified output coordinates. Conclusion. The value of the practical results obtained by the authors is in development of the control system for electric propulsion drive as a totality of units performing mathematical operations with both controllable parameters and non-observable physical coordinates. This system is the basis for development of the software to be used in the microchip-based control system of electric propulsion plant for Project 22220 multi-purpose nuclear icebreaker currently under construction.
