Development of an interactive energy management web application for residential end users
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: Energy efficiency, as the effective use of energy, is recognized as one of the simplest ways to
improve the sustainable use of resources and by implication involves the end-user.
The 2008 power crisis ...
Design and analysis of a gearless, direct grid, permanent magnet induction wind generator
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: In this study a new type of gearless, direct-drive wind generator, which can be connected directly to the grid,
is proposed. The working characteristics of this generator are based upon the principles ...
Direct grid connection and low voltage ride-through for a slip synchronous-permanent magnet wind turbine generator
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: The slip synchronous-permanent magnet generator (SS-PMG) is a direct-driven, direct-to-grid generator
for wind turbine applications. This investigation focuses on achieving automated grid connection ...
Optimisation methods applied to compensator placement
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: The optimal placement of different types of compensators on electrical networks is a complex
task faced by network planners and operations engineers. The successful placement of these
devices normally ...
Design and analysis aspects of radial flux air-cored permanent magnet wind generator system for direct battery charging applications
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The electromagnetic and mechanical design aspects of optimally designed doublesided
rotor radial flux permanent magnet wind generators with non-overlap aircored
(iron-less) stator windings are analysed ...
Design of tapered and straight stator pole switched reluctance machines
(Stellenbosch : Stellenbosch University, 2000-04)
ENGLISH ABSTRACT: This thesis deals with the design and optimisation of medium power traction switched
reluctance machines with tapered and straight stator poles. Only the prototype of the
tapered stator pole machine ...
A reliable telemetry software design for a satellite system
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: One of the requirements for satellite telemetry systems is the provision of reliable
telemetry data to allow accurate monitoring of the satellite status. This thesis focuses on
the design of telemetry ...
The comparison of AC and DC alternatives for sub-transmission networks
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: Recent advances in semiconductor technology extended the economic power range
for DC transmission to just a few MW. Network planners need tools to compare AC
and DC alternatives in order to find the ...
Opportunities for in-line, transistorbased technologies on MV and LV power distribution networks
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: Once more opportunities exist for innovative technologies to be applied on MV and LV
power distribution networks to meet the new challenges set by government through its
National Electrification Programme ...
Some design aspects of the multi flux barrier rotor reluctance synchronous machine
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: This thesis deals with different design aspects of the multi-flux barrier rotor of the reluctance synchronous
machine (RSM). The effect of the different designs on the performance of the RSM is
investigated ...
