2.9 DeterminationofShadowFlickerImpactintheVicinityofProposedWindFarms

Shadow flicker is one of themost important “optical emissions” fromwind turbines,which must be considered during the planning phase. Rotating rotor blades cause aflashingeffectbyperiodicalblockingoff the sunlight,whichmay causedisturbanceofresidents in the vicinity of wind farms. For this reason, the determination of opticalemissions fromwind turbines forms an essential part of the approval process in theplanningphaseofwindpowerprojects.

4.1 TechnicalManagementofWindFarms

One activity of DeutscheWindGuard is the technicalmanagement ofwind farms. Thetechnicalmanagement is the basis for a successfulwind energy project, for onlywellmaintainedwindturbineswithahightechnicalavailabilityassureinvestorsandbankstheforecastedcalculatedprofits.ThetechnicalmanagementofwindfarmsbyDeutscheWindGuard follows the requirements of insurance companies for status‐orientedmaintenanceofwindfarms.

Technicalmanagement includes constantmonitoring via remote control, implementa‐tion and organisation of immediate assistance in the case of error removal, ordering,organisationaswellascheckingofmaintenance.Thepreparationofmaintenance–andmanagement protocols and periodical reports is also part of the service. At present,DeutscheWindGuardmanagesatotalof212windturbineswithatotalin‐stalledcapaci‐tyofmorethan471MW.Adetailedlistofthesewindturbinesand/orwindfarmsisgiv‐eninAppendix8.3.

6.2 AcousticNoiseMeasurementsonWindTurbines

DeutscheWindGuardConsultingGmbH is accredited for acousticnoisemeasurementssince2012andachieved conformitywith theFördergesellschaftWindenergieundan‐deredezentraleEnergien(FGWe.V.)requirementsforacousticnoisemeasurementsonwindturbines.

Standardisedacousticnoisemeasurementsonwindturbinesareusuallyperformedac‐cordingtoIEC61400‐11.Majorquantitiestodescribethenoisecharacteristicsofawindturbinearetheoverallsoundpowerlevel,socalled“tonality”(mostlyduetomechanicalnoisecomponents)andimpulsivity(periodicalsoundpowerfluctuations).Inindividualcases, analysis of low frequencynoise is of interest.Weoffer acoustic noisemeasure‐ments according to the state‐of‐the‐art standards and procedures as well as specificanalysesrequestedbyourclients.Ingeneral,standardisednoisemeasurementsarealsopartoftheturbinecertificationprocess.

Thedominatingpartoftheacousticnoiseemissionisusuallycausedbytheaerodynamicnoisefromtherotorblades.Adverseeffectsontheoverallsoundpowerlevelcanespe‐cially be causedby anunfavourable designof blade tips. Anothernoise source isme‐chanicalnoisecausedbythegearbox,thegenerator,differentaggregatesortheinvert‐er. In general, differentnoise sources canbe identifiedby adetailed analysis of noisespectra(i.e.frequencyanalysis).Thisway,valuableindicationscanbeprovidedtowindturbinesuppliersorowners,onhowtoreducethenoiseemissionandhowtoremedyunwantednoisecharacteristics.WindGuardstaffmemberslookbackonmanyyearsofexperiencegainedfromhundredsofcommercialnoisemeasurementsand,also,variousinternationalresearchprojectsonaerodynamicnoisereduction,optimisationofmeas‐urementproceduresandoutdoornoisepropagation.

After awind farmhas been commissioned, verification of the acoustic noise emissionmayberequestedby localauthorities–sometimesatregular intervalsthroughouttheoperatingperiodofwindfarms,inordertoensureobservationofthe(legal)noiselimits.Also, noise verification measurements are offered by Deutsche WindGuard, utilisingmeasurement techniques specifically developed for outdoor measurements underwindyconditions.



WindGuardoffers:
