基于极点配置的双馈风力发电机并网系统的静态稳定性分析
摘要:为研究双馈风力发电机的运行特点及并网时系统的静态稳定性，基于双馈风力发电机电压、磁链方程，考虑不同传动轴系对风机运行的影响，推导建立单台风电机组两质量块动态模型。结合小信号分析法，对风机所在系统进行静态稳定性分析。在不同控制模式下，存在稳定与不稳定运行情况，通过极点配置法，在不完全可控的情况下令系统的稳定性得到明显改善。

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.
