ENGLISH ABSTRACT: This document details the design process of a 97 kW microhydro system for Roman Bay Sea Farm in Gansbaai in the Western Cape Province of South Africa.
It contains a literature study of microhydro power, with a focus on the use of
Pump-as-Turbine technology and direct-drive systems. The literature study leads
to several possible concepts for the project, which are then evaluated and the
most suitable design is found to be a reverse running pump that powers a
different pump through a direct drive system. Experimental data from KSB is
used to test the accuracy of various correlations that can be used to generate
turbine-mode operation curves from pump curves. The final design parameters
for the complete system are then determined, and presented along with a cost benefit
analysis. / AFRIKAANSE OPSOMMING: Hierdie verslag dokumenteer die ontwerpsproses van ‘n 97 kW mikro hidro stelsel vir Roman Bay Sea Farm in Gansbaai in die Wes-Kaap van Suid Afrika. Dit
bevat ‘n literatuurstudie van mikro hidrokrag, met ‘n fokus op Pomp-as-Turbine
en direk-gekoppelde stelsels. Die literatuurstudie lei tot ‘n aantal moontlike
konsepte vir die projek wat dan evalueer word sodat die mees gepaste ontwerp
gekies kan word. Dit word gevind dat ‘n pomp wat verkeerd om hardloop en ‘n
ander pomp direk van krag voorsien die mees gepaste ontwerp is.
Eksperimentele data van KSB word gebruik om die akkuraatheid van verskeie
korrelasies te toets wat gebruik kan word om turbine-mode gedrag van pomp
kurwes te bepaal. Die finale parameters van die hele stelsel word dan bepaal en
word dan saam met ‘n koste-analise aangebied. / Centre for Renewable and Sustainable Energy Studies
