Summary

 
Object and purpose of research.This paper studies automated frequency-controlled electric propulsion drive being an element of electric propulsion system aboard a multi-purpose nuclear icebreaker currently under construction. The purpose of this work is to develop a flow chart of electric drive control system based on vector control algorithm that meets a number of tough requirements to dynamic properties of electric propulsion drive.
Subject matter and methodsInput data for this work were scientific and technical data given in the literature on electric drive theory, as well as personal findings and multi-year experience of the authors in the R&D activities related to electric propulsion of ships. Solution to this problem is based on designing a frequency-controlled electric propulsion drive as a closed-loop automatic regulation system with several control channels, each of these, in its turn, consisting of several circuits synthesized as per cascade compensation principles.
Main results.The result of this work is a control system for frequency-regulated electric propulsion drive based on 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 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.
