LVRT capability of wind farms

2013 12th International Conference on Environment and Electrical Engineering, 2013
Nowadays wind turbines are generally required to offer ancillary services similar to those provided by conventional generators. One of the most important services wind turbines must offer is to stay connected to the grid in fault situations delivering the reactive current specified in the recent grid codes.

LVRT-DGFACTS devices in wind farms

2011 International Conference on Power Engineering, Energy and Electrical Drives, 2011
This article compares the results recorded in the connection of three types of DGFACTS (DSTATCOM, DVR, UPQC) to a wind farm in order to resolve the issues of LVRT requirements on wind farms equipped with wind turbines with squirrel-cage induction generators.

Impact of LVRT Control on Transient Synchronizing Stability of PLL-Based Wind Turbine Converter Connected to High Impedance AC Grid

IEEE Transactions on Power Systems, 2023
With large scale of wind turbines connected to high impedance AC grid, transient synchronizing stability of PLL (phase locked loop) based WTC (wind turbine converter) during LVRT (low voltage ride through) is increasing concerned.

Enhanced Excitation Converter With Parallel/Series DC-Link Based on TAB for DFIG to Improve the LVRT Capability Under Severe Grid Faults

IEEE transactions on power electronics, 2023
The low-voltage ride-through (LVRT) capability of the doubly-fed induction generator (DFIG) based on the conventional excitation converter is insufficient under severe grid faults.

Control Strategy Study of DFIG with LVRT

2009 International Conference on Energy and Environment Technology, 2009
In recent years, the proportion of the wind power in the grid is increasing rapidly. When the grids faults results in voltage decline, the widespread tripping of wind generators could lead to transient instabilities and local or overall blackouts. So it is concerned that the wind turbines merge into the grid and the request of the low voltage ride ...

Eliminating the Need for a Less Strict Requirement for the Negative-Sequence LVRT Current of Type-III Wind Turbine Generators in the IEEE 2800 Standard

IEEE Transactions on Sustainable Energy, 2023
Similar to emerging regional grid codes, the recently approved IEEE 2800 Standard mandates that inverter-based resources (IBRs) generate negative-sequence current during low-voltage ride-through (LVRT) conditions. The 2800 Standard requires that the IBRs'

Study on Transient Characteristic of the DFIG LVRT

Advanced Materials Research, 2013
In order to analyze the operational capability of the low voltage ride through ( LVRT) of a gird-connected wind turbine with doubly fed induction generator (DFIG) effectively, it is necessary to evaluate operation characteristics of DFIG under a grid fault.By using the transient principle of the flux of stator and rotor, the expressions of transient ...
