Control of Harmonics in marine Electrical Power Systems

Dissertation Topic:

The extensive use of power electronics on vessels and offshore installation, especially on electric propulsion ships, has an impact on the voltage quality of the power distribution system. This effect is called harmonic distortion. High-harmonic distortion levels are appearing as a result of the increased use of power-electronic drive converters for electric propulsion, drilling and pumping applications, and many other uses of variable speed-drive (VSD) systems. The source of harmonic distortion is the interaction of non-linear loads with the impedance of the supply network. A bad quality voltage distribution system, due to harmonic distortion, has effects like heating of the induction motors, transformers and capacitors, overloading the neutral and generally creates malfunction or damage in the electrical equipment that is installed on board. Power electronics technology creates non linear loads and is used in applications such as variable frequency drives for motor power/speed control. Its increasingly find its way to shipboard or offshore applications.

This dissertation will encompass in the topic of fundamental physics of harmonics, the specific power quality issues related to the harmonic distortion of voltage supplies caused by the operation of electronic devices which draw non-linear currents from the voltage supplies will be addressed. Harmonics filters enable the reduction of harmonic distortion on electrical power systems. In order to find an effective, efficient and low cost way to control the voltage distortion, different kind of harmonics filters must be analyzed in technical and economic point of view. In order to achieve these goals different types of harmonic filters will be connected to variable-speed drives systems.

The matlab/simulink software will be used in order to investigate the technical characteristics of different typed of harmonics filters and then, from those simulations will be find which kind of harmonic filter is the best solution.

I would like to ask you if somebody has better ideas on this topic, please advise me, I will wait for new proposals.

The project must be 80 pages
