Siemens Wind Turbine SWT-2.3-108

The industrystandard, redefinedThe Siemens 2.3-MW family has firmly establisheditself as the tried and tested workhorse for reliability,with a range of rotor diameters for different windconditions. Our new SWT-2.3-108 adds a new,larger rotor to the family, setting a new standardfor productivityGreater output from lower wind speedsSince wind turbine technology was in its infancy, Siemenshas been a major driver of innovation. And with itsenhanced reliability and productivity in low to moderatewind speeds, the new SWT-2.3-108 is yet another exampleof the commitment to customers’ success.Longer blades. More energyIn recent years, Siemens created a product line specificallyto extract more energy from moderate wind conditions.The SWT-2.3-108’s innovative rotor blade design nowextends productivity even further. The new 108-meterrotor with its unique blade properties is perfectlyoptimized for sites with low wind speeds.Your trusted partnerWith its combination of robust and reliable wind turbines,highly efficient solutions for power transmission anddistribution and a deep understanding of the entireenergy market, Siemens continues to be a leadingsupplier. Long-lasting customer relationships based onan excellent delivery record provide for a sound,sustainable and profitable investment.With over 140 years of experience in the energy sector,a strong focus on renewables and a global network ofhighly skilled and trained employees, Siemens has provenitself to be a trustworthy and reliable business partner.And it will continue to be in the future.For superior availability, reliability and a lower levelizedcost of energy, look no further than the new SiemensSWT-2.3-108 turbine.

Siemens’ Turbine ConditionMonitoring® system instantlydetects deviations from normaloperating conditionsNo compromise on reliabilitySWT-2.3-108: The newest member of an extremelyreliable product familySiemens wind turbines are designed to last. The robustdesign of the SWT-2.3-108 allows for trouble-free outputthroughout the complete lifecycle of the machine.Instead of glueing the blades together from a number ofspars and shells, they are cast in a single process. This notonly enables both low weight and enormous strength,there are no glue joins which could potentially exposethe blades to cracking and lightning damage.Climate control within the nacelle protects vitalequipment from the outside environment. The windturbine also offers controlled-wear strategies for criticalcomponents, which results in a further reduction ofmaintenance costs.Safety firstSafety is at the heart of all Siemens’ operations. Fromproduction to installation, operation and service, Siemensstrives to set the standard in safety.The fail safe capabilities within a wind turbine, combinedwith Siemens’ superior lightning protection system, aredesigned to enhance security for the turbine.Advanced operations supportGiven the logistical challenges associated with servicingwind farms, Siemens has equipped its turbines with aTurbine Condition Monitoring® system that reduces theneed for on-site servicing.Siemens’ Turbine Condition Monitoring® system comparesthe vibration levels of the main nacelle components witha set of established reference spectra and instantlydetects deviations from normal operating conditions.This allows Siemens to proactively plan the service andmaintenance of the wind turbines, as any unusual eventcan be categorized and prioritized based on severity.Using the knowledge gained from monitoring thousandsof wind turbines over the years, Siemens’ experts areexceptionally skilled at analyzing and predictingoperational anomalies. This allows Siemens to proactivelyplan service and maintenance activity as each event canbe categorized and prioritized based on severity.Siemens can then determine the most appropriate courseof action to keep the wind turbine running at its best.
