Time Constant Model Analysis of Double Fed Induction Wind Generator

摘要：

Double Fed Induction Generator (DFIG) model studied in this paper includes Stator flux transient state--2nd order, Rotor current transient state--2nd order, Rotor current controlled dynamic state--2nd order, Phase-Locked Loop dynamic state--1st order, Rotating coordinate system dynamic state--1st order, Pitch angle dynamic state--1st order, and Shaft dynamic state--1st/3rd order. Because stator flux transient is considered, voltage and flux in rotor equation would be coupled strongly due to action of PLL, resulting in difficulty in DFIG model analysis. In order to deal with this problem, according to Lyapunov’s eigenvalue theory, DFIG model is derived in some detail and analyzed from the time constant point of view in this paper. In terms of different characteristic of application problems in power system analysis, the DFIG model above-mentioned is classified suitably so as to adapt various applications.
