This paper gives a complete assessment of the various strategies used to decorate the skills of Low Voltage Ride Through (LVRT) of Double Fed Induction Generators (DFIG) primarily based wind turbine systems (WT). As the world is using about 20% to 25% of renewable energy from wind using DFIG primarily based WT machine is at once connected to the grid without the digital interface of power, as a result the terminal voltage or reactive electricity output can’t manage. Therefore, unique LVRT approaches based at the implementing additional active interface technologies had been proposed within this paper. Many techniques are developed nowadays to overcome the issue of this low voltage due to faults. This paper tries to define such active methods to short the gap by way of presenting a complete analysis of these LVRT strategies for DFIG based WECS in terms of overall adaptive performance, complexity of controllers, and cost effectiveness. Here characteristic of this paper is to highlight the methods for increasing the ability of LVRT relying on the configuration of the relationship into 3 major areas according to its grid integrations. In this paper hybrid (series-shunt) connections of FACT devices are used in WECS to study its effectiveness and benefits. The mathematical models of the whole system are simulated through MATLAB simulink and results are discussed.
