Fulfillment of low voltage ride-through requirement of D-PMSG based wind energy conversion system using generator-rotor inertia

摘要

As a result of increase in the installed capacity of wind power systems around the world, providing Low Voltage Ride-Through is one of the prime requirements of Grid Codes. Wind farms are now required to comply with stringent connection requirements which include remaining connected during grid faults, providing reactive power support, achieving system stability and voltage regulation. The paper analyzes and implements LVRT requirements for Permanent Magnet Synchronous Generator based Wind Turbine Generator system using MAT-LAB/SIMULINK. With the help of the proposed control strategy, wind turbine stays connected to the grid during fault condition, and the excess energy is stored in generator-rotor inertia instead of dissipating it through a chopper resistor.
