Designing Passive Harmonic Filter of Electric Propulsion System on Tanker Ship

Power Accounting for Ship Electric Propulsion

Coarse and accurate power accounting methods for ship electric propulsion are observed and compared. For the purpose of analysis, the propulsion system has been separated into two units, namely the ship load and the motor drive. In the load model, variation of such factors like static and dynamic hull resistance and efficiency is explored while the supply characteristics, drive loading, propell...

Designing Electric Propulsion Systems for UAVs

hydrodynamic performance of the modern ship propulsion system

this paper presents numerical calculations for podded propulsion system using vortex theory and potential panel method. the method discretizes the surface boundary of the body (propeller +pod+strut) and obtained the vortex and propeller surface and potential on strut and pod. a model propeller and strut are considered for these calculations and the results of pressure distribution, flow field a...

Optimal Control of Double Star Synchronous Machine for the Ship Electric Propulsion System

this work focuses on modelling, optimal control and numerical simulation of the ship electric propulsion system provided by a double star synchronous machine. The in-depth analysis of the operation of the propulsion system of the vessel allowed us to model elements of the propulsion system. Thus, a non-linear global model was obtained describing the operation of the entire propulsion system. Th...

harmonic limits using wide - spectrum passive harmonic filter

T O ADDRESS CONCERNS ASSOCIATED WITH ELECTRICAL POWER system harmonic distortion on ships and offshore oil rigs and platforms, marine regulating bodies have introduced strict new harmonic standards. These standards define the acceptable level of harmonic voltage distortion allowed on the vessels they certify. High-harmonic distortion levels are appearing as a result of the increased use of powe...
