摘要
利用部分惯量中心(PCOI)等值,在频域中将多机系统等值成二机系统,在等值二机系统上运用极点配置法,得出了关于PSS放大倍数和时间常数的解析方程组,方程组求解采用Newton-Raphson迭代法。这种方法得出的PSS参数同时考虑了多机因素的影响和多模之间的协调,能够给出较为满意的多机PSS参数协调结果,一个4机系统的算例证明了所提方法的有效性。
The multi-machine power system is equivalent to two-machine power system by using partial center of inertia (PCOI) transformation.Pole disposition method is used for the two-machine power system to form analytical equations about the parameters(amplification and time constant)of power system stabilizers.Then Newton-Raphson method is used to solve these equations. The above method considers the internal influence existing in multi-machine system and the coordination between different modes and can obtain the satisfactory coordinated parameters.An example on a 4-machine power system demonstrates the effectiveness of the proposed method.
