Small Wind Power in Austria

about 300 installed small wind turbines in Austria

no reliable information available

mainly in rural areas, 2 SWT in urban areas

Small Wind Power in Austria

Windtronics SWT


Austrowind SWT

Bad quality and safety issues

Negative experiences

e. g. Austrowind, Windtronics

Unreliable information about performance

provided by manufacturers

promise of high energy yields

no measured power curve

Burdensome permission procedures

different rules in every federal state

No incentives

Feed-in-tarif for large wind turbines: about 9 cent/kWh

R&D Project: Small Wind Power Systems


The project was funded by the Austrian Climate

and Energy Fund.

Verification of quality, safety, reliability and performance

of 13 SWT available on the Austrian market

for at least 12 month

Energy Research Park Lichtenegg

test and measurement infrastructure

with 9 stands for SWTs

additional stands for power curve and noise

measurement

annual wind speed: 5,18 m/s at 19 m


Power Curve

Results

power curves of some manufacturer in part higher than theoretical maximum of Betz

all measured power curves are lower than the power curves provided from the

manufacturer

largest difference was 50 %


theoretical

max. of Betz

Longterm evaluation

verification of quality, safety, reliability and performance

continuous operation and measurement for more than 12 month under practical

conditions

at the Energy Research Park in Lichtenegg

extreme wind and climatic conditions

Recording of operating data, such as energy yield, maintenance, downtimes,

defects and errors,…


Winter at the Energy Research Park Lichtenegg

Longterm evaluation

less than half of the tested SWTs reached the excepted energy yield

improve the understanding of turbulent

wind conditions and

the impact of turbulences on the

performance of SWT

Which technology is most suitable for

a rural site with low TI and

an urban site with high TI?

Method:

testing and measuring

a HAWT and a VAWT

in an urban (high TI) and rural (low TI)

environment
