A System-based Modeling and Simulation of a Floating Production Storage and Offloading (FPSO) Electric Power Systems and Core Loss Analysis of Synchronous Generator and Induction Motor
Abstract
In this dissertation, a system based modeling and simulation were investigated for FPSO power system components and a few experimental results were evaluated to determine core losses in a synchronous generator under non-sinusoidal current.
Modeling and simulation results are presented to predict both the utility and the motor side challenges caused by different harmonic distortion levels. VFD was modeled as a rectifier and an inverter isolated by the DC link in the middle of the rectifier and the inverter in order to have faster and more accurate analysis of harmonics on both the utility and the motor side. Finite element analysis shows that reducing current harmonic level causes lower core losses in the machine.
Each component from the simulation, specifically synchronous generator, phase shifting transformer, multipulse rectifier, multilevel inverter, umbilical cable and induction motor, can be replaced or combined with any other topologies which is one of the biggest benefits of the system based modeling and simulation.
