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.
