中文摘要:

针对风电场(基于异步风电机组构成)并网对原有电力系统静态电压稳定性的影响,结合异步发电机组的无功-电压特性,采用收敛潮流雅克比矩阵特征结构分析法,分析风电场的接入对系统静态电压稳定性的影响。本文在标准IEEE-30节点系统中并入风电场进行仿真分析,研究表明风电场的接入使得原有系统静态稳定裕度降低,弱稳区域扩大,负荷裕度降低。与其他方法相比此方法更好的实用性和灵活性,适用于大型电力系统。

英文摘要:

For the impact of intergration wind farm(based on asynchronous wind turbines constitute)on static voltage stability of power system and combines asynchronous generators reactive-voltage characteristics, eigenvalue structure analysis of convergence flow Jacobian martrix is employed, analysis of the influence of wind farm access to the system static voltage stability. In this paper, based on the standard IEEE-30 nodes system incorporated into the simulation analysis of wind farms. Studies have shown that access to the original system of wind farms makes the static stability reduced, weakly stable regions expand and the load margin reduced. This method is better compared with the practicality and flexibility of other methods, suitable for large-scale power systems.
