Low voltage ride-through enhancement in DFIG-based wind turbine
2016 IEEE Electrical Power and Energy Conference (EPEC), 2016Wind farms are regarded as large-scale power plants with interconnected systems, where all systems interact with each other to improve the efficiency of the plant and thus enhance the quality of the output power. However, the conventional centralized controller is inappropriate for such plants.

Low voltage ride through for a wind turbine based SCAG
2015 3rd International Renewable and Sustainable Energy Conference (IRSEC), 2015This paper develops a control strategy for a large wind turbine based on the squirrel cage asynchronous generator (SCAG). In addition, the transient behavior during Low Voltage Ride Through (LVRT) of the system is studied. To this end, the wind turbine connected to the grid is controlled in such way to inject maximum power into the grid and provide a ...

Low voltage ride through capability of gas engine driven units
22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013), 2013Recent developments in European grid code regulations demand the inclusion of decentralized generation (DG) into their requirements. Gas-engine-driven generators, as a part of Europe’s DG, need to comply with these requirements; and therefore procedures to receive admission are formed.

Effect of Low Voltage Ride Through Technologies on Wind Farm
2007 IEEE Canada Electrical Power Conference, 2007Doubly fed induction generators (DFIG) offer many advantage when used with wind turbines. Given their configuration, they are particularly sensitive to grid faults. As many countries now require wind turbine generators to remain connected to the grid during faults, low voltage ride through solutions are being developed to fulfill this new requirement ...

Low Voltage Ride-Through protection techniques for DFIG wind generator
2013 IEEE Power & Energy Society General Meeting, 2013Due to the rapid increase of penetration level of wind generation connected directly to the bulk power system grid, a new grid codes have been issued that require Low-Voltage Ride-Through (LVRT) capability for wind turbines so they can remain online and support the electric grid post fault events instead of instantaneous tripping.

Low voltage ride through capability of single-phase induction machines
e & i Elektrotechnik und Informationstechnik, 2018Stochastically occurring voltage sags as they may occur with low quality of the power supply may significantly affect the operational behavior of single-phase starting and running capacitor assisted induction machines. In contrast to three-phase machines which are still subjected to a rotating field, even during voltage sags, the single-phase machines ...
