Thesis (MEng)--University of Stellenbosch, 2000. / ENGLISH ABSTRACT: Recent advances in semiconductor device development pushed a large number of network
devices onto the market. These devices can solve network problems more effectively and
economically than ever before. Network planners need tools to analyse and implement such
devices to help solve the largest network problem in South Africa: voltage regulation. Rural
networks experience the majority of voltage-regulation problems in South Africa. The
networks are long sub-transmission and reticulation networks and are modelled by two
generic networks, namely a radial network and a two-source ring network. The equations
describing voltage regulation for the generic networks are developed and implemented in
PSAT, a software analysis tool. The voltage regulation for two case studies that represent the
two generic networks are analysed. Four generic network devices are defined and various
control methods for these devices are developed to solve the network problem. The aim of
PSAT is to help the network planner to quickly evaluate a number of possible solutions and to
choose the best solution for further studies. This is demonstrated with the aid of the case
studies. PSAT provides a sturdy platform on which future developments, such as stability
analyses, can be built. However, PSAT can already function as a stand-alone analysis tool to
solve voltage regulation as a network problem. / AFRIKAANSE OPSOMMING: Onlangse vooruitgang in halfgeleier ontwikkeling het 'n groot aantal netwerktoestelle op die
mark geplaas. Hierdie toestelle kan netwerk probleme doeltreffender en meer ekonomies
oplos as ooit vantevore. 'n Behoefte aan 'n pakket wat netwerkbeplanners in staat stelom die
netwerktoestelle te analiseer, is geïdentifiseer. So 'n pakket sal hulle help om die vernaamste
netwerkprobleem in Suid-Afrika, nl. spanningsregulasie, op te los. Die oorgrote meerderheid
spanningsregulasie probleme word op die platteland ondervind. Plattelandse netwerke word
gekenmerk deur lang sub-transmissie en retikulasie netwerke. Hierdie netwerke word met
behulp van twee generiese netwerke gemodelleer. 'n Radiale netwerk en 'n dubbelbron ringnetwerk
word aangewend om enige plattelandse netwerk te analiseer. Vergelykings is vir
spanningsanalise ontwikkel en in PSAT, 'n analitiese sagteware pakket, geïmplementeer.
Twee gevallestudies is gedoen om die twee netwerke afsonderlik voor te stel en die
vergelykings van PSAT te evalueer. Alle netwerktoestelle is in een van vier generiese
kategorieë geklassifiseer. Modelle is vir elk van die kategorieë ontwikkel vtr
spanningsregulasie analise. Die doel van PSAT is om die netwerk beplanner te help om
vinnig en effektief soveel moontlik opsies te ondersoek as oplossings vir 'n spesifieke
netwerk probleem. PSAT is reeds 'n alleenstaande pakket wat in die toekoms uitgebrei sal
word om na die analise van stabilitietsprobleme te kyk.
