Application of quantitative feedback theory to robust power system stabiliser design.
This thesis aims to verify the use of quantitative feedback theory (QFT) as a viable tool for designing power system stabilisers (PSS) for a single machine infinite bus system. The result of the QFT design is verified by ...
An in-depth study into the various factors contributing to the unexplained line faults on a large high voltage network.
The Eskom Transmission Network experiences an exceptionally high number of line faults, the cause of which, may not be correctly identified. This thesis analyses a number of all the possible factors responsible for causing ...
An application specific low bit-rate video compression system geared towards vehicle tracking.
The ability to communicate over a low bit-rate transmission channel has become the order of the day. In the past, transmitted data over a low bit-rate transmission channel, such as a wireless link, has typically been ...
The detection of fires under high voltage transmission lines.
Fires generate heat and propel burning material into the air above and around the core of the fire. Fires under power lines reduce the breakdown strength of the air insulation due to the influence the heat and particles ...
Design and implementation of a thyristor controlled series capacitor for research laboratory application.
The power transfer capability of a transmission line is determined by the magnitude of the voltage at each end of the line, angle difference of these voltages and the impedance of the line. This impedance is mainly inductive. ...
Performance of all dielectric self-supporting fibre optic cable in high voltage environments.
Power utilities around the world are now in the practice of installing fiber optic cables on their high voltage transmission networks. These high-speed communication channels can, not only transmit data needed for utility ...
A study of high voltage direct current conductor corona in a purpose built corona cage.
The main aim of this study was concerned with the design and commissioning of a corona cage, which could be used under Direct Current (DC) conditions. The cage was designed based on empirical formulas and equations as ...
Routing performance in ad hoc networks.
An ad hoc network is a multi-hop wireless network in which mobile nodes communicate over a shared wireless channel. The network is formed cooperatively without specific user administration or configuration and is characterised ...
Fuzzy logic power system stabiliser in multi-machine stability studies.
Conventional power system stabilisers (PSS) are designed to eliminate poorly damped, low frequency power oscillations that occur between remote generating pools or power stations, due to different types and settings of the ...
