Power quality

Grid codes are becomingly increasingly stricter. Requirements for low- / under-voltage ride through (LVRT / UVRT) and harmonics are getting tighter, making it harder for wind turbines to comply. So, as the wind energy market increases, it becomes ever more crucial to verify and characterize the way your turbines perform in respect to power quality.

Comprehensive power quality measurements
Our power quality testing for turbines and associated systems gives you the assurance and guidance you need. We don’t just test your component to make sure it works; we also help you identify how to make it better. 

Working together with all the relevant technical parties and original equipment manufacturers (OEMs), we put the turbine through a wide range of tests to explore how it behaves in all kinds of situations. We test against many international guidelines, including FGW TR3, IEC 61400-21, IEEE 1453, 519, VDE 4105 and TSO requirements. We then present these comprehensive power quality measurements in a report that allows you to:

  • Verify if a specific component complies with specific grid codes
  • Understand and improve how it performs
  • Characterize its performance for a power flow/grid connection study
  • Identify and mitigate issues related to harmonics, turbine tripping, etc
  • Conduct over voltage ride through testing, protection relay testing and commissioning testing
