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3种控制方法抑制 系统低频振荡的有效性。

关 键 词:电力系统,低频振荡,可控硅串联补偿,线性控制

Abstract: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.
Keywords:electric power system low-frequency oscillation thyristor-controlled series compensator(TCSC) linear control
