Abstract

A damping control strategy to improve the dynamic characteristics based on SVGs is proposed in this paper. The shaft model, induction generator model, converter control model and angle control model of DFIG (Doubly Fed Induction Generator) are presented. The alternating voltage control model and the voltage control model of SVGs (Static Var Generation) are built, the mathematical model of the damping control module is proposed. The dynamic stability after the integration of wind farm is detailed analyzed with two-area four-machine system example and the availability of this damping control strategy is also confirmed.
