【Abstract】To study the operating characteristics of doubly-fed wind generator and the static stability of the connected grid, this paper considers the influence of different drive shafts on the operation of wind turbine based on the voltage of doubly-fed wind generator and flux linkage equations, derives the dynamic model of the two mass block of single unit. By combining the small signal analysis method, this paper analyzes the static stability of the wind turbine system. Under different control modes, there are stable and unstable running conditions; and the stability of the system is significantly improved by the pole assignment method in the case of incomplete control.
