Siemens at WindEnergy Hamburg tradeshow at Hall 6, Booth B6.362
New Siemens onshore wind turbine offers less noise at optimum performance
| • | SWT-3.3-130LN for noise sensitive sites |
| • | Noise level at 104.9 decibels |
| • | Serial production in early 2017 |
High performance at low to medium wind speeds – that’s what the new Siemens low
noise SWT-3.3-130LN wind turbine offers customers. The new model operates at a
reduced rotor speed compared to the SWT-3.3-130, and includes aerodynamic addons
to its rotor blades. Utilizing these add-ons, it can be operated at a noise level of
104.9 decibels. The new machine will be available in early 2017 in parallel with two
additional onshore models launched by Siemens at the WindEnergy 2016 trade
show in Hamburg.
The fast air stream passing the tips of the rotor is primarily responsible for the
characteristic noise of a wind turbine in operation. Aeroacoustic optimizations of the
B63 blades allow silent operation of the new SWT--3.3-130LN turbine: In addition to
vortex generators on the blade surface, trailing edges are equipped with a
combination of serrations and combs, known as the new Siemens DinoTail Next
Generation. Each combed teeth element creates fine vortices at the point where the
fast air stream from above the blade profile meets the slower air stream flowing
below. As a result, the aerodynamic noise from the trailing edge of the blade is
reduced significantly. The result is high performance at low rotor speed. This
enables the SWT-3.3-130LN to reach a maximum rating of 3.3 megawatts (MW)
with a noise emission reduced by nearly two decibels compared to the SWT-3.3-130
launched in 2014.
The SWT-3.3-130LN wind turbine represents a combination of proven Siemens direct drive technology and cutting edge aerodynamics. Even at an average wind speed of 6.5 meters per second, it harvests an Annual Energy Production (AEP) of around 11 gigawatt-hours. At 8.5 meters per second, the AEP actually reaches 16 gigawatt-hours.
“With our SWT-3.3-130LN wind turbine, our customers bank on reliable technology and add the advantage of a significant effect in noise mitigation,” says Thomas Richterich, CEO Onshore der Siemens Wind Power and Renewables Division. “The new model closes a gap in our portfolio: Wherever an IEC IIA class turbine is needed but noise protection requirements set limits, this wind turbine is the definite first choice.”
