【摘要】 应用特征值法求解多机系统同步发电机组次同步扭转振荡往往会发生维数灾问题,本文依据次同步扭转振荡模式具有便于分离研究的特点,在Perez—Arriaga,I.J.的选模分析的基础上,补充了适于计算次同步扭转振荡问题的选模逆迭法和优化法,形成了选模复合解算的一种新算法。试算表明这种算法稳定可靠,可有效地克服维数灾问题;更多还原

【Abstract】 According to the character that modes of SSR are easy to be separated from full modes of a system, a novel method is "presented for the analysis of SSR in multimachine power system with complex compensation network. The method not only, effectively overcomes the difficulties of solving eigenvalues under high dimension condition, but also bring time saving on calculation.更多还原
