8th International Conference on Power Electronics - ECCE Asia, 2011
In this paper, a Low Voltage Ride Through (LVRT) control strategy for variable speed full scale Wind Turbine Generator System (WTGS) is proposed. Grid-connected wind power system should satisfy LVRT requirement when grid fault occur, and the variable speed full scale WTGS has advantage of satisfying LVRT compared with the fixed speed WTGS. The proposed

2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy), 2017
Rotating electrical machines are designed at many levels and from a number of different points of view. The development of powerful computation engines in previous decades allowed for the use of numerical methods in electromagnetics. In electrical machines, the magnetic field effect the dimensions of iron parts due to magnetostriction.

In present scenario, the Doubly Fed Induction Generator (DFIG) is contributing more than 50% in wind power generation. The computation of core losses and copper losses are essential to analyse the electric machine performance. In this paper, DFIG is modelled and analysed using ANSOFT MAXWELL which results in distribution of magnetic flux and magnetic ...

This paper proposes the dynamic voltage and current assignment (DVCA) strategies for doubly fed induction generator (DFIG) wind power system, which is fed by nine-switch converter (NSC). With the proposed DVCA strategies, the voltage and current capacities of switches in NSC are dynamically assigned to the rotor- and grid-side branches, depending on ...

Effect of low voltage ride through (LVRT) characteristic on voltage stability
IEEE Power Engineering Society General Meeting, 2005, 2005The number of wind installations has grown worldwide at unprecedented rates in recent years. As well, the average size of the installations has increased due to the advent of larger capacity machine, variable speed technology, and an increasing number of off-shore sites.
