Newly introduced SWT-3.0-101 direct drive turbine
• Reduces complexity and increases
reliability and maintainability
• 50% fewer parts, half the parts of the
conventional geared turbine
• Simplified design for easier
transportation, erection and maintenance
• Compact and light weight
• Generator located at the front of the
nacelle, between the nacelle itself and
rotor hub; reduction of the equipment
inside the nacelle results in a shortened
4m length

Siemens Boulder Wind R&D Team
Goal - Supporting Siemens Wind Power to lower cost of electricity
by increasing energy production, lowering turbine cost and
improving reliability
Siemens Wind R&D Boulder is focused on the following technology areas:
Loads – Reduce mechanical loading per unit of energy = lighter blades and structures =
cost savings = Lower COE
Aerodynamics – Improve efficiency = higher capacity factors = Lower COE
Controls- Improve energy output and lower loading = Lower COE
Wind Power Meteorology –optimize Turbine design and operation of wind farms = Lower
COE
Product Integrity - Support prototype and turbine testing in the Americas

Boulder CRADA, Introduction
•
Cooperative Research And Development Agreement between
Dept. of Energy, DOE/ National
Renewable Energy Lab, NREL and Siemens Wind Power
•
•
A SWT-2.3-101 wind turbine is erected at NWTC, Boulder
Budget: DOE/NREL $5M
Siemens $9M
•
Time plan: Jan 2009- Jan 2012
• In a close cooperation between
NREL and Siemens numerous test
campaigns and data analysis will
be performed

Boulder CRADA
Technology Development Project
Objectives
The primary objective is to gain
detailed knowledge of
performance, aerodynamics,
noise emission and structural
characteristics of the SWT-2.3101 wind turbine being operated at
a severe wind condition site with
strong wind shear and high
turbulence intensity.
New measurement technologies
The measured data will serve as a
unique and valuable verification
and validation data set for
improvement and further
development of wind turbine design
codes used in Siemens Wind
Power
The test campaign is part of a
Cooperative Research and
Development Agreement (CRADA)
between Siemens Wind Power A/S
and National Renewable Energy
Lab, NREL in Boulder, Colorado
The wind turbine being tested is
the Siemens SWT-2.3-101, which
is rated at 2.3 MW and has hub
height of 80 m and a rotor diameter
of 101 m
The turbine was erected October
2009 and tests are planned to run
until January 2012.

is instrumented with six sonics
anemometers and four cup
anemometers and vanes
A Windcube LIDAR is located 280
m upstream of the turbine. The
LIDAR can measure inflow wind at
several heights between 10 and
250 m
Flow Visualization
Tufts on the suction side of the root section for
visualizing the surface flow. Here with two rows of
VGs. The separated region is clearly seen.
Investigation of Vortex Generators on the outer part of the
blades using oil flow visualization. The flow is on the
suction side at rotor radius and centered at about ~ 44 m.
The VGs are removed between the two dashed lines.
