LVRT of Grid Interfaced Variable Speed Driven PMSG for WECS during Fault
Abstract—Wind energy conversion systems have become a focal point in the research of renewable energy sources. This is in no small part due to the rapid advances in the size of wind generators as well as the development of power electronics and their applicability in wind energy extraction. The voltage of the direct driven permanent magnet wind generators (PMSG) is variable due to the intermittent nature of the wind energy. Fluctuating voltage and power is of major concern in the converter based grid connected wind generation systems. An inverter is essential for the interfacing of the wind source with the AC network. This paper discusses the interconnection issues of permanent magnet wind generators to local grid as per prevailing grid standards during healthy and fault conditions. The fault ride-through topology for PMSG has been demonstrated using MATLAB Simulink based simulation.
Index Terms—Variable Speed Control, Wind Energy Conversion System, PMSG, Low Voltage Ride-through (LVRT), Power Quality.
