Sumbawa Island, Indonesia, has substantial wave
energy potential derived from the Indian Ocean. This significant
wave energy potential, along with the Indonesian government's
support for energy transition and zero carbon policies, necessitates
detailed location-specific assessments of wave energy converter
performance. One wave power plant that has reached a
Technology Readiness Level of eight is the oscillating water
column (OWC) type. Wave energy converter research using an L
shaped OWC chamber was conducted in a two-dimensional wave
flume at the Coastal Engineering Laboratory of the National
Research and Innovation Agency. The study involved varying the
wave period characteristics found in Sumbawa Island, Indonesia,
to evaluate the performance of the Wells turbine as the converter.
The research results indicate that the performance of the L-shaped
OWC with a Wells turbine is influenced by changes in wave
periods. The water oscillation within the chamber affects the air
pressure inside the chamber and the turbine duct of the OWC,
which in turn impacts the turbine's rotation speed (RPM) and the
overall performance of the wave energy converter. The best
performance was achieved with a wave period scenario of 7.5
seconds at 7,089 RPM, while the lowest performance was observed
with a wave period scenario of 11.5 seconds at 5,190 RPM.
