Review of Low Voltage Ride Through Methods in PMSG

In this paper discussed about low voltage ride through (LVRT) scheme for permanent magnet synchronous generator (PMSG) and wind energy conversion system. Wind generation system has potential application for the grid support. The voltage of the direct driven permanent magnet wind generators (PMSG) is variable due to the intermittent nature of the wind energy. With increasing penetration of wind turbine (WTs) in the grid. Grid connection codes in most countries require that WTs should remain connected to the grid to maintain the reliability during and after a short-term fault. The controllers for grid-side converters are coordinated to provide fault ride-through capability. The generator side is forced by space vector modulation and grid implemented field oriented control (FOC).
