LONG BEACH, Calif.–(BUSINESS WIRE)–Edge
Wind was spun out of Edge
Aerodynamix to develop wind power applications of the Conformal
Vortex Generator (CVG) tape and tab technology that they developed for
aircraft wings and helicopter rotor blades. This technology increases
annual wind turbine energy production, provides protection from erosion
and impacts, reduces drag caused by leading edge erosion, reduces
startup speeds, and reduces vibrations. The CVG tape and tab is
installed rapidly by two technicians on a rope rig or aerial high lift
with minimal surface preparation.
Edge Wind has worked with the U.S. National Renewable Energy Laboratory
to collect data over an eleven month period on the performance of the
CVG and Tab relative to industry standard edge protection tape on the
600 KW CART 2 wind turbine in Golden, Colorado.
5 minute average power and wind speed over five data was collected. The
data was filtered to remove noise from unstable wind. Data for the
baseline was limited at wind speeds over 15 meters per second and data
for the CVG + Tab is still being collected. The improved performance
over the CVG and Baseline is expected to continue once data is collected
for higher wind speeds.
NREL reported a 22.2% increase in KWH production from the CVG and the
Tab relative to a conventional leading edge taped blade along with a
20.9% increase for the CVG alone. This shifts the power curve
between the cut-in and full production wind speeds. “This technology has
the potential to add the equivalent of an extra 100 GW of wind capacity
globally without having to install a single additional turbine,” said
Edge Wind CEO Ranbir Sahni. (See edgewind.net for details.)
AEP for CVG+TAB was limited due to reduced wind strength during test
period (which is ongoing). AEP based only on improvement for range of
test data, not extrapolated to show probable AEP for equal wind range.
Edge is currently looking for field trial sites with GE, Vestas, and
Siemens Gamesa turbines and low turbulence in the US & EU to collect the
data required to CFD model and optimize the design for each turbine
brand. Based on our experience from the B737 test process, we expect
that turbine model specific optimization will yield additional increases
in power output.
