Abstract

A comparison among series connected auxiliary devices; SFCL, DVR, TCSC, and SDBR is performed in terms of fault ride through capability improvement of a fixed speed wind generator systems, controller complexity, and cost. The tested system consists of one synchronous generator and one squirrel cage induction machine based wind generator, which feed an infinite bus through a double circuit transmission line. Simulation results show that all the devices performs well under symmetrical and unsymmetrical faults, however, in spite of the DVR controller complexity it has the best performance among all devices in terms of voltage, and speed control of wind generators at lower cost as compared to the SFCL which is costliest among all devices. The SFCL is the most efficient in reducing the fluctuations of active power and stator current of the wind generators. The SDBR is the cheapest, and shows a better enhancement in damping active power and limiting fault current than DVR and TCSC.
