Abstract
According to recent advances in military science and electrical engineering on the one hand and on the other hand, subject of replacing diesel engines with electro motors (due to higher efficiency, less maintenance, better performance, better dynamics, etc.), this paper discuss about electric ships and simulation of the boat drives with electric motors. Since the construction of electro motors up to 1970th (which is the start point of Power Electronic that result in speed control of AC motors), the propulsion system hadn’t been use system uses electric motors. But after that, due to the high response rate, quick start, high efficiency, good reliability, easy maintenance and low cost ... Day by day the use of AC motors became more significant. Since Modeling and Simulation of vector control of AC motor for boat propulsion (with Load model) hasn’t been written as an detailed article, so the purpose of this paper is analyze of vector control performance of induction motor as vessels motor. The Contents of this article is this respect; after Introduction, various components of the propulsion system are discussed that with Load model will give propulsion system of vessel. In this paper after describe of vessel propulsion system, the vessel with electric propulsion motors has been discussed and finally an electric propulsion system for typical vessel is designed. The result of modeling and simulation of this project in conclusion part is discussed.
