Transient Stability Simulation of Wind Generators Taking DC-offset Current into Consideration

Abstract

In standard simulations of short circuit faults in power systems, it is common to neglect transients of the transmission networks and armature circuits of generators. Therefore, it is not possible by standard method to evaluate particular phenomenon arised from the armature transient. It is well known that the standard method can not evaluate the backswing phenomenon caused by the armature transient. This paper applies a new method, which can approximate the DC offset currents that arise from the armature transient, to transient stability simulation of power system including wind generators.
