Abstract


Podded propulsion ship as a way of the electric propulsion system , applied for many years , especially passenger ships , icebreakers , engineering ship . Its excellent performance make it more widely used . Podded propulsion is a branch of the turn - pod propulsion system . Domestic late start in this area , there is a large gap between the developed countries . Therefore it is necessary to conduct some research . Firstly to introduce marine electric propulsion development process based on the full collection of related technical information and turn pod electric propulsion system advantages . And an experimental system designed for the requirements of the experimental system by the host computer (PC) and PLC control system, the inverter and the motor to the implementing agencies . The complete system hardware selection and PLC software writing . Designed to achieve a 360 - degree rotation control pod , the rotation speed closed-loop control , rotary position detection function . The thesis is divided into five chapters , the first of the article describes the development of electric propulsion ship overview details the development and characteristics of turn - pod podded electric propulsion thrusters . Next are described for the various components involved in the design . The article describes in detail the theoretical basis of the test design , test equipment and test methods . Control mode and selection test which involves the basic principle of the induction motor speed control , the principle of the drive , the basic components of the inverter system as well as the basic speed control principle is described in detail . The article also detailed the PLC 's principle , functional , modern PLC control function of the technology and related modules , and the related expansion module selection , followed by hardware design and selection software . After the experiment achieved satisfactory results .
