| 摘 要： | 将含参数约束的线性优化方法应用于交直流混合系统的电力系统稳定器和基于电压源型换流器的高压直流输电系统附加阻尼控制器的参数协调优化中。该算法考虑了不同阻尼控制方式间的相互影响和作用，在迭代过程中通过修正优化可行域区间，使系统低频振荡模式对应的特征根最终移动到复平面上期望区域内。系统的特征值分析和时域仿真结果验证了上述方法的有效性和实用性。

| Abstract: | The authors propose a coordinated tuning algorithm for power system stabilizer (PSS) and supplementary damping controller (SDC) of voltage source converter-based high voltage direct current (VSC-HVDC) transmission system in a multi-machine AC/DC system by use of linear optimization method containing parameter constraints. Considering the interaction between PSS and SDC of VSC-HVDC, the characteristic roots corresponding to low-frequency oscillation modes of power system are shifted to the desired region on the complex plane by modifying the interval of optimal feasible region. The results of both system eigenvalues analysis and time-domain simulation verify the effectiveness and practicality of the proposed method. |
