摘要
分析了小干扰稳定性分析方法的现状及存在的问题,介绍了大型电力系统分析软件NETOMAC所特有的特征值分析程序NEVA中适用于大规模互联电网小干扰稳定性分析的特征值算法。该程序及其算法具有极强的实用性,为互联电网的区域间振荡分析及阻尼控制研究提供了一种应用级的有效手段。最后以跨欧洲互联电网为例进行研究,说明了所介绍程序和算法的强大分析能力。
The present situation and existing problems of small signal stability analysis methods are analyzed. The eigenvalue algorithm suitable to small signal stability analysis for large-scale interconnected power systems, which is involved in the eigenvalue analysis program NEVA that is characteristic of large power system analysis software NETOMAC, is presented. This program and its algorithm are very practicable and can be used as an effective applicable means for the research of inter-area oscillation analysis and damping control in interconnected power systems. Taking the UCTE/CENTREL power system for example, the research results show that the analysis capability of the presented program and its algorithm are powerful.
