Application of Model Based System Engineering (MBSE) with Ship Design Arrangement Tool of advanced zero emissions Power, Propulsion and Energy Systems in Maritime Technology

The main aim of the master thesis was to create a design tool for the arrangement of the Propulsion, Power and Energy (PPE) systems during the conceptual design stage in cooperation with Maritime Research Institute of Netherlands (MARIN). Within MARIN, a recent and novel methodology known as Model Based Systems Engineering (MBSE) is implemented...

Analysis of Active Control Methods to Improve Converter Reliability in Wind Turbines

Converters are the essential devices in the energy transformation process from the wind generators to the grid. Power electronic semiconductors have a high share of failures in the power electronic converters. Therefore, the reliability based on lifetime of power semiconductor generates more and more attention. This thesis presents a comparison...

Low Voltage Ride Through Control for the Brushless Doubly-Fed Induction Generators

Stability and security of the grid are two vital aspects of energy supply. To keep the grid stable, it is necessary that the electricity plant can control and protect the mechanism. In the past, traditional plants could meet these requirements. Nowadays, the share of sustainable power sources in total electricity generation has become so...
