摘要

提出了一种求解大规模电力系统全部机电振荡模态的逆幂算法.首先忽略调速器模型、负荷电动机模型(对未装有电力系统稳定器(PSS)的发电机组进一步忽略励磁调节器模型)对机电振荡模态的影响

以形成合理的降阶系统

由于降阶前后系统的机电振荡模态一一对应

因而降阶不会影响原系统机电振荡模态的个数和机电振荡模态与机组的相关性.采用QR法得到降阶系统的所有机电振荡模态

以这些模态作为原系统机电模态的近似值

进而利用逆幂法追踪原系统的所有机电振荡模态.根据电力系统特性应用了稀疏技术

提高了求取机电振荡模态的速度.对2009年西北电网系统4个典型运行方式的计算结果表明了算法的有效性和应用于大规模电力系统的潜力.

Abstract

An inverse power algorithm to obtain all electromechanical modes for large-scale power system is proposed. The influences of governor

motor load and excitation regulator in the generator without PSS on electromechanical oscillation modes are ignored to establish an order-reduction system. The electromechanical oscillation modes of the reduced-order system correspond one to one with that of the original system

thus the order reduction exerts no effect on the number and the related generators of the electromechanical oscillation mode. These modes are regarded as the approximation of electromechanical oscillation ones of the original system

and all original system electromechanical oscillation modes are traced by inverse power algorithm. The results of four typical operation modes in Northwest Power Grid in 2009 indicate the validity and potentiality.
