Wind Low Voltage Ride Through Testing

Low Voltage Ride Though (LVRT) Testing

Before any generating plant can be connected to the grid, the system operator normally requires a certificate. This in turn requires the measurement of electrical characteristics and also verification of the plant’s Low Voltage Ride Through (LVRT) capability. UL offers LVRT testing and measuring services to determine the electrical characteristics and grid compatibility of wind turbines.

UL tests to the following standards:

  • Technische Richtlinien für Erzeugungseinheiten und -anlagen, Teil 3 (TR3): Bestimmung der Elektrischen Eigenschaften von Erzeugungseinheiten und -anlagen am Mittel-, Hoch- und Höchstspannungsnetz; Rev. 23; Stand: 01.05.2013; Herausgeber: Fördergesellschaft Windenergie und andere Erneuerbare Energien (FGW e.V.)
  • IEC 61400-21: Wind turbines – Part 21: Measurement and assessment of power quality characteristics of grid connected wind turbines; Edition 2.0 2008-08.
  • Particular Grid Code requirements which may vary from country to country.
