In the field of grid integration UL carries out measurements and evaluations to determine the electrical characteristics and grid compatibility of:• wind turbines• solar inverters• combustion engines (cogeneration, Biogas machines)• wind and solar farms• controller for wind and solar farms

The Services Include:

Our Qualifications:

• More than 330 measurements of electrical characteristics worldwide

• Measurements are carried out according to the following guidelines:

- IEC 61400-21: Measurement and assessment of power quality characteristics of grid connected wind turbines

- MEASNET: Power quality measurement procedure

- DIN VDE V 0124-100: 2012-07: Grid integration of generator plants – Low-voltage

• Power Quality - Flicker and voltage fluctuations

in normal operation and during switchings

- Harmonics up to 9 kHz

• Active power control - Power peaks - Active power set-point control - Ramp rate limitation - Power reduction due to overfrequency

• Reactive power control - Reactive power capability - Set-point control

• Disconnection from the grid - Grid protection (under-/overfrequency,

under-/overvoltage) - Cut-in conditions

• Response to temporary voltage drops - Ride-through - Reactive current injection - Behavior during the fault and after

fault clearance

UL carries out measurements and evaluations to determine the electrical characteristics of wind turbines, solar inverters and of other generation units/systems according to the currently applicable standards (e.g. IE C 61400-21 and FGW TR 3) and is accredited according to ISO/IEC 17025:2005 and approved by MEASNET and FGW.
