摘要
风电并网对系统稳定性的影响不容忽视,如何控制风电机组从而提升系统的稳定性也是值得研究的工作。采用小干扰法分析了风电场采用虚拟惯量控制对提高系统静态稳定性的影响,并采用IEEE14节点系统进行仿真分析。通过分析可知,随着风电惯性的增大,系统主导振荡模式的特征根会远离虚轴,系统的静态稳定性会得到提高。
The impact of wind power grid connection on the stability of the system cannot be ignored.How to control the wind turbine to improve the stability of the system is also worth studying.This paper analyzes the effect of virtual inertia control on improving the static stability,and the IEEE14 node system.According to the analysis in this paper,with the increase of wind power inertia,the characteristic root of the system dominant oscillation mode will be far away from the virtual axis,and the static stability of the system will be improved.
