Wind Turbine Electrical Characteristics Testing

Testing for grid connection and limit verification

In the field of grid integration, UL Solutions carries out measurements and evaluations to determine the electrical characteristics and grid compatibility of wind turbines. The measurements are required for planning grid connections and verifying applicable limits, but they also facilitate an exact analysis of the electrical behavior of the generation units and systems, which is important for their design, development and optimization. In this connection, UL Solutions also carries out calculations of required grid capacities as well as power quality and background interference measurements.

UL Solutions tests to the following standards:
