摘要
给出了多机电力系统静态稳定计算的建摸原理,推导了考虑励磁调节系统动态行为的全系统线性化状态矩阵公式,并设计了基于Matlab语言的运算程序。该程序可以计算系统特征值和每一特征值的机电回路相关比,可以满足多机电力系统低频振荡分析的需要。使用该文方法及其程序与电力科学研究院开发的电力系统分析综合程序(PSASP6.2)分别对EPRI-36节点系统典型算例进行计算比较。二者的全部特征值、机电回路相关比等计算结果完全一致,验证了所述方法正确、有效。
This paper provides a principle of calculating small - signal stability for multi - machines power system. Considering the dynamic behavior of excitation systems, the state matrix of entire system is deduced. The calculating program based on Matlab is designed, which may compute the eigenvalues of system and electromechanical relative coefficients, and support the analysis of low frequency oscillation in multi - machines power system. The large typical power system formed by 36 buses （EPRI - 36） is calculated with the method mentioned in this paper and PSASP6.2. It is showed that the same results are obtained and the effectiveness and common usefulness of this method and program are proved.
