Abstract :
This paper analysis the electromagnetic transient response characteristics of DFIG under symmetrical and asymmetrical cascading grid fault conditions considering phase-angel jump of grid. On deriving the dynamic equations of the DFIG with considering multiple constraints on balanced and unbalanced conditions, phase angel jumps, interval of cascading fault, electromagnetic transient characteristics, the principle of the DFIG response under cascading voltage fault can be extract. The influence of grid angel jump on the transient characteristic of DFIG is analyzed and electromagnetic response characteristics under both symmetrical and asymmetrical failure types are compared.
