POWER ELECTRONICS IN SHIP PROPULSION ELECTRIC MOTORS



INTRODUCTION :

The predominant type of prime movers for DP propulsion plant is Electric Drive .Practically every DP propulsion device installed in newly constructed vessels as well as in most of the conversions is driven by an electric motor. In recent years, variable speed AC Drives has become available and has been used in some applications for DP propulsion. The most commonly used motor drives are:
DC converters, or SC ....etc

A magneto-hydrodynamic generator (MHD generator) is a magneto-hydrodynamic device that transforms thermal energy and kinetic energy into electricity. MHD generators are different from traditional electric generators because they operate at high temperatures without moving parts. MHD was developed because the hot exhaust gas from an MHD generator can heat the boilers of a steam plant, increasing overall efficiency. MHD was developed as a coverage cycle to increase the efficiency of electric generation, especially when burning coal or natural gas ....etc

Magneto Hydro Dynamic power generation technology

INTRODUCTION

The Magneto Hydro Dynamic power generation technology (MHD) is the production of electrical power utilising a high temperature conducting plasma moving through an intense magnetic field. The conversion process in MHD was initially described by Michael Faraday in 1893. However the actual utilisation of this concept remained unthinkable. The first known attempt to develop an MHD generator was made at Westing hou ....etc

A magnetoplasmadynamic propeller (MPD) is a form of electrically powered spacecraft propulsion that uses the Lorentz force (the force on a particle charged by an electromagnetic field) to generate thrust. It is sometimes referred to as Lorentz Force Accelerator (LFA) or (especially in Japan) MPD arcjet.
Generally, a gaseous material is ionized and fed to an acceleration chamber, where the magnetic and electric fields are created using an energy source. The particles are then driven by the Lorentz force resulting from the interaction between th ....etc

The steering gear system has three main parts:

control equipment
power unit
transmission to the rudder stock.
In brief, the operation of the steering gear can be explained as - With the help of the control system, a signal of desired rudder angle is sent from the bridge. This signal activates the power unit with which the rudder is attached. The rudder moves with the help of the power unit till the right angle is reached. ....etc

ABSTRACT

The Magneto Hydro Dynamic (MHD) propulsion thruster is designed to use magneto hydrodynamic force generated by sending electric current through a magnetic field created in sea water by superconducting magnets. The principle of MHD propulsion is to apply the Fleming's left hand rule of electromagnetics to sea water directly .In this propulsion system magnetic field is created in sea water by magnets fixed on a hul1. When electric current is sent to sea water at right angles to the magnetic field, and electromagnetic force (Lorentz fo ....etc
