摘要
提出了一种电力系统静态稳定分析的综合方案 ,并开发了相应的软件包 .对中小规模系统采用全部特征值分析的 QR法 ,必要时在多运行方式下协调设计 PSS;对大规模系统采用部分特征值分析的 AESOPS算法 ,并提出了确定初始特征值和相应受扰机 ,以及防止算法丢根的方法 .
A complementary scheme for small signal stability is proposed and a program package is developed.The QR transformation method is used for analyzing small and medium sized powersystems and the AESOPSalgorithm for large scale systems.The initial estimates of eigenvalues in the AESOPS algorithm are obtained using QR method with reduced order generator model and a method for protecting the AEPOPS algorithm from eigenvalue losing is given.The resultsof Shandong powersystem in China show that the proposed method is effective.
