Analysis of doubly-fed induction generator based wind power system for voltage sag

배전선로 전압강하에 대한 이중 여자 풍력발전시스템 특성 해석

This paper represents the generating principles of the doubly-fed induction generator (DFIG) based wind power system and developes a simulation model of DFIG by using PSCAD/EMTDC. In addition, this paper analyzes the steady state operation and the transient operation during the voltage sags in the power common coupling. The voltage sags are occurred by three phase line-to-ground faults and full-voltage startup of an induction motor in the simulation.
