摘要
在建立含可控硅串联补偿装置（TCSC）的电力系统线性化数学模型的基础上，提出了TCSC在系统中最佳位置的选择方法，并对可控串补控制系统分别采用全状态反馈控制、线性二次型最优控制和输出反馈最优控制时阻尼系统低频振荡的作用进行了分析，证明了TCSC采用线性控制方法可以提高系统的稳定性。最后以三机系统为例，利用频域仿真计算验证了所讨论的三种控制方法抑制系统低频振荡的有效性。
Based on the linear dynamic mathematical rnodel of power system including thyristor-controlled series compensator(TCSC). this paper presents a method of selecting optimal installation location of TCSC. On the condition of TCSC controlsystem using all-state feedback control. linear quadratic optimal control and output optimal control respectively. the damp oflow-frequency oscillation is analyzed. The stability of power system is improved when linear control scheme is used by TCSC.At last. the simulation results in frequency domain for a three-machine power system illustrate the effectiveness of dampinglow-frequency oscillation when TCSC using the composed control methods.
