S88 VG Case Study

suzlon-aep-increase

UpWind’s Vortex Generator (VG) solution has been installed on thousands of turbine blades and proven a positive AEP increase on several turbine technologies. It is important to prove the upgrade solution on each turbine technology and blade type to give owner’s a clear picture of expected production (AEP) increase.

This case study examines the effects of the VG solution on S88 turbine technology, proving their value with a scientific analysis by Smart Blade GMBH, and comparing it against an independent analysis completed by DNV GL. DNV GL independently assessed the AEP increase and came to the same conclusions as the SmartBlade analysis described below.

The report shows the methodology Smart Blade used to determine the final result of
a 2.5% increase in AEP.VG solution has been proven on the 
S88 technology with a 2.5% AEP increase.

Key Lessons Learned 

  • Actual AEP increase from VG installation
  • AEP calculation methodology
  • Power vs Power approach
  • Computation of relative yield differences

UpWind’s VG solution has been proven on the S88 technology with a 2.5% AEP increase. Over the past 3 years, the solution has also been proven on multiple other turbine models through extensive collaborative testing with operators. The post processing methodology that is used by Smart Blade is vital to giving owner/operators a clear understanding of how the VG solution will affect their AEP, and what ROI they can expect from their investment in VGs.
