摘要

晶闸管控制串联电容器(TCSC)和电力系统稳定器(PSS)的调谐和性能分析是缓解低频振荡现象的重要问题。为了消除所有不良模式，将TCSC与PSS控制器在不同负载条件下的协调问题表述为优化问题。通过最大阻尼比增强机电模态阻尼是粒子群优化算法确定的目标函数。然后，在SMIB上实现了开发的方法。为了验证算法的有效性，在不同工作模式下进行了特征值分析和非线性时域仿真。

Design and Performance Evaluation of TCSC and PSS to Mitigate Low Frequency Oscillations

Tuning and performance analysis of thyristor controlled series capacitor (TCSC) and power system stabilizer (PSS) is most important issue to mitigate the phenomena of low frequency oscillations. To damp out all poor modes, coordination between TCSC and PSS controllers under different loading conditions is formulated as optimization problem. Enhancement of damping of electromechanical modes (EM) through maximizing of damping ratio is the objective function which fixed by Particle Swarm optimization (PSO) algorithm. Developed approach is then, implemented on SMIB. To validate effectiveness of proposed algorithm, eigenvalue analysis as well as nonlinear time domain simulation is demonstrated considering different operating modes.
