LVRT Enhancement Capability of DFIG based WECS using PI Controller

Wind Energy is one of the most rapidly growing form of non-conventional Energy sources. By the end of 2015 was ranked the fourth in the world for wind power capacity. The usage of wind turbines along the grid creates a large number of problems and one of them is Low Voltage Ride Through (LVRT). The purpose of this paper is to enhance the LVRT capability of Double Fed Induction Generator (DFIG) by using a PI controller along with several changes along the grid side. It is required that the voltage should ride through even at a value less than 10-15% of the correct value during voltage sags Keywords - LVRT, DFIG, PI, Sags, Non-Conventional.
