Bidirectional converter for a stirling energy system
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: This thesis discusses a 23 kW three-phase AC bus system that is utilized together with the
“Stirling Energy System (SES) Integrated Solar Dish-Stirling Module” to function as a
mini-grid for off-grid ...
Transient modelling of induction motors in a petrochemical plant using Matlab
(Stellenbosch : Stellenbosch University, 2008-03)
ENGLISH ABSTRACT: The behaviour of induction motors at a petrochemical plant under transient conditions was
investigated with the view to improve plant immunity to voltage fluctuations. The benefits of
using a ...
A three-phase AC/AC matrix converter system
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: The thesis discusses the analysis and design of a three-phase-to-three-phase direct
AC-AC matrix converter. A background study of the various matrix converter topologies
and their modulation strategies ...
Transformerless series dip/sag compensation with ultracapacitors
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: This thesis covers the development of a transformerless series dip compensator. Of all known power
quality problems, voltage dips are the greatest reason for concern. Series injection dip compensators
offer ...
Dynamics and Energy Management of Electric Vehicles
(Stellenbosch : University of Stellenbosch, 2007-12)
The work presented in this thesis forms part of the participation of the University of Stellenbosch in an electric vehicle project. The thesis deals with three aspects of the dynamics and energy management of the electric ...
Evaluation and implementation of anti-islanding methods for converter-fed distributed generation
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: As the number of distributed generation units connected to a distribution network
increase, the possibility of island formation increases. An island is formed when
distributed generation units continue ...
