Utilisation of line surge arrestors to improve overhead HVAC and EHVDC line performance under lightning conditions.
(2020)In high lightning areas, lightning strokes play an important role in the performance of overhead EHV AC and DC lines. A single lightning stroke, that terminate on the earth wire and/or tower can lead to back flashovers. ... -
Optimal placement of statcom controllers with metaheuristic algorithms for network power loss reduction and voltage profile deviation minimization.
(2020)Transmission system is a series of interconnected lines that enable the bulk movement of electrical power from a generating station to an electrical substation. This system suffers from unavoidable power losses and ... -
Integration of distributed energy resources (Solar PV) a revenue impact study and tariff optimisation analysis for EThekwini Municipality.
(2020)The South African energy generation sector is naturally evolving from a traditionally vertically integrated structure to a more liberalised one via the promotion of local generation. The main drivers of such a transition ... -
Induction motor steady-state performance under varying quality of supply and stator winding short circuit location using negative sequence current.
(2019)Abstract available in the PDF. -
Impact of different pulse width modulation (PWM) techniques on the performance of a three phase Z-Source inverter (ZSI).
(2019)Abstract available in PDF. -

A study of the variation of electric distance and electric strength with the type of voltage stress and portion of the gap covered by flames.
(2019)South Africa has a large network of high voltage substations and transmission lines (over 28 000 kilometers) across the country designed to supply power to households, industry and businesses, railways and mines. This ... -
Mitigation for floating neutral in distribution systems.
(2019)The rollout of electrification programme in deep rural communities has significantly improved the quality of life for people of South Africa, some who never anticipated that they would have access to electricity. Most rural ... -
Interruption reduction at substations using battery energy storage systems.
(2019)Reliable electrical power supply is vital in the modern society and electrical distribution utilities are responsible for ensuring continuity of supply. South Africa is experiencing a rapid increase in electrical power ... -
Impacts and solutions on vehicle to grid (V2G) infrastructure.
(2019)To deal with the problem of global warming and dependency on oil, the need for emmissionfree transport has brought electric vehicles to life. The main aim of this thesis is to investigate, analyze and propose solutions ... -
Upgrading existing power supply at the Port of Durban.
(2019)The Port of Durban’s (PoD’s) power supply is from EThekwini Electricity (EE) at a supply voltage of 33 kV via two main intake substations that is Stanger Street Substation (STS) and Durban Harbour Intake (DHI) Substation. ... -
Buckling analysis of nano-composite laminate using finite element analysis.
(2019)In this dissertation, the buckling problem of a nanocomposite laminate is investigated. The laminate consists of uni-directional nanocomposite plies fabricated with a graphene filled polymer matrix reinforced with carbon ... -
Consideration of the effects of symmetrical and asymmetrical voltage dips in the control and operation of a grid-connected doubly-fed induction generator.
(2020)Grid integration of Type 3 Wind Energy Conversion Systems (WECS) based on the doubly-fed induction generator (DFIG) is a great challenge since the direct connection of the stator side to the grid makes it susceptible to ... -
Environmental pollution effects on insulators of high voltage overhead transmission line for locomotives.
(2019)The primary focus of this research is to report thoroughly on the addressed key questions of the proposal and to successfully compile a simulation based on environmental pollution effects on insulators of high voltage ... -
Combined heat and power (CHP) retrofit for supplemental on-site power generation at Engen oil refinery.
(2019)This thesis is a critical evaluation of an opportunity project for on-site generation of electricity at the ENGEN refinery in Durban, South Africa. The key equipment discussed is a 2.5MW special purpose backpressure turbine ... -
Improvement of voltage and dynamic performance of transmission power networks using distributed superconducting magnetic energy storage systems (D-SMES)
(2019)Over the past 30 years, a device known as a Distributed Superconducting Magnetic Energy Storage (D-SMES) has been under development and proposed to solve various grid performance challenges. A D-SMES is device with a ... -
Integrated framework for green and sustainable energy resources within the South African context.
(2019)On the back of energy shortages, hiking electricity tariffs, mitigating climate change, and the initiative taken by households to generate electricity through renewable resources, it is important to study green technology, ... -
