Modeling and control of a three-phase grid-connected inverter under fault conditions
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialThe aim of this paper is to study the behavior of a three-phase inverter with an RL filter powered by a renewable energy source and connected to a grid under fault conditions. The novelty of the work lies in proposing a ... -
Power quality disturbances assessment during unintentional islanding scenarios. A contribution to voltage sag studies
(2019-08-20)
Article
Accés obertThis paper presents a novel voltage sag topology that occurs during an unintentional islanding operation (IO) within a distribution network (DN) due to large induction motors (IMs). When a fault occurs, following the circuit ... -
Voltage recovery influence on three-phase grid-connected inverters under voltage sags
(2019-02-12)
Article
Accés obertFaults in power systems cause voltage sags, which, in turn, provoke large current peaks in grid-connected equipment. Then, a complete knowledge of the inverter behaviour is needed to meet fault ride-through capability. The ... -
Voltage support experimental analysis of a low-voltage ride-through strategy applied to grid-connected distributed inverters
(2018-07-27)
Article
Accés obertIn recent decades, different control strategies have been designed for the increasing integration of distributed generation systems. These systems, most of them based on renewable energies, use electronic converters to ... -
Voltage support provided by three-phase three-wire inverters with independent reactive phase-current injection
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Article
Accés obertDuring voltage sags, three-phase three-wire power inverters can provide voltage support with several current injection strategies. In general, good results are ob- tained, except in overvoltage situations when one or more ...
