Thesis (MEng)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: This thesis presents the design of a DSP based controller system for an auxiliary
converter for generic energy storage connection to a line-interactive power
compensator. The aim is to utilize a wide range of energy storage systems and
incorporate them into the existing power compensator. This was done by adding
a second converter to the system. The new controller was developed to control
this converter and thereby the energy storage. A study was done on lead acid
batteries, flow batteries and flywheels in order to gain a basic understanding of
these systems and identify the requirements for their control. Based on these
findings, a new DSP based controller and measuring system was developed. To
test the new system a dc to dc converter was implemented for the control of lead
acid and flow batteries. A dc to ac converter was also tested for the control of
flywheel energy storage. / AFRIKAANSE OPSOMMING: Die tesis handeloor die ontwerp van'n DSP gebaseerde beheerstelsel vir 'n Iyninteraktiewe
on-onderbreekbare kragbron met drywings-kompensasie met 'n hulp
omsetter vir algemene enegiestoor koppeling. The doel is om 'n wye
verskeindheid energie store in die huidige drywings elektroniese stelsel te
inkorporeer. 'n Tweede omstetter is by die stelsel gevoeg om die energie stelsel
te beheer. 'n Nuwe beheerder is ontwikkel om die omsetter te beheer en
daardeur die energie stoor. Loodsuur batterye, vloei batterye en vliegwiele is
ondersoek om 'n basiese begrip te vorm en te identifiseer wat nodig is vir die
beheer van sulke energie store. Die nuwe DSP beheerder en meetstelsel is
ontwikkel gebaseer op hierde ondervindings. Om die nuwe beheerstelsel te toets
is 'n gs na gs omsetter geïmplementeer vir die beheer van loodsuur en floei
batterye. Die omsetter is geherkonfigureer na 'n gs na ws opstelling en getoets.
Die konfigurasie word gebruik vir die beheer van vliegwiele.
