| Summary: | 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. |
