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 ...
The design and testing of a superconducting programmable gate array
(Stellenbosch : University of Stellenbosch, 2006-03)
This thesis investigates to the design, analysis and testing of a Superconducting Programmable Gate Array (SPGA). The objective was to apply existing programmable logic concepts to RSFQ circuits and in the process develop ...
An investigation into the phase noise of quartz crystal oscillators
(Stellenbosch : University of Stellenbosch, 2007-03)
As secondary objective an introduction to the quantification, theory and measurement of phase noise is presented to make this field of study more accessible for the novice to the field. Available phase noise theory is ...
A comparative study of insulator materials exposed to high voltage AC and DC surface discharges
(Stellenbosch : University of Stellenbosch, 2009-03)
The rising worldwide popularity of HVDC applications for power transmission purposes increases the need to study the performance of commonly used insulation materials when exposed to this voltage type. The aim of this ...
