Low-Voltage-Ride-Through-Assistenzsystem für dezentrale Erzeugungseinheiten
e & i Elektrotechnik und Informationstechnik, 2014Wahrend eines Kurzschlusses im Netz nahe einem Synchrongenerator kommt es aufgrund einer verminderten Leistungsabgabe wahrend des Fehlers zu einer Beschleunigung des Rotors. Dies kann zu unerwunscht hohen Polradpendelungen bis hin zum Verlust des Synchronismus des Generators fuhren.

Low-voltage ride-through simulation for microgrid systems
2017 IEEE International Conference on Electro Information Technology (EIT), 2017In contrast to the previous generation of power grid codes, recent standards require that distributed energy resources (DERs) provide low-voltage ride-through (LVRT) capabilities during grid faults. Consequently, the high penetration of DERs in today's power system requires an efficient method of controlling the active and reactive power of those ...

Testing Low Voltage Ride Through capabilities of solar inverters
Electric Power Systems Research, 2013Abstract The increase in the rated power of PV inverters has brought with it new requirements, such as Low Voltage Ride Through and reactive power compensation. Field tests in PV plants are too expensive in terms of production losses, and therefore laboratory tests have become a simple, flexible and inexpensive alternative.

Comparison of several Low Voltage Ride Through Attached Equipment
2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019The power plant auxiliary drive system will work abnormally or even trip due to frequency converter voltage drops, which might be caused by transient state process of auxiliary power system or the external grid. Low voltage ride through (LVRT) is an effective way to solve the above problem.

Low-voltage Ride-through Capability Characterization of Wind Farms
Electric Power Components and Systems, 2012Abstract This article characterizes low-voltage ride-through capability of wind farms. Critical clearing time has been used in the literature as a measure of the transient stability of induction generators and, hence, an indication for low-voltage ride-through capability of single wind turbine generators.
