摘　　要：本文推导了装有可控串联电容补偿装置的电力系统的线性化模型，利用复转矩系数法分析了可控串补阻尼控制向振荡提供阻尼的机理。在此基础上，通过对振荡模式的分析，提出了如何选取可控串联补偿装置的装设地点。利用线性最优控制规律设计了阻尼控制器，并讨论了阻尼控制器的控制参数和系统振荡模式的关系。特征值分析与非线性仿真验证了本文所提方法的有效性和正确性。In this paper the extended linear model of power system with TCSC installed was developed.By use of the complex torque coefficient method,the principle of suppressing oscillations by TCSC’s damping control was also explained.The oscillation modes were analyzed and as a result an index to select the placement of TCSC and its input signal was explored.Using optimal linear control theory,the damping control of TCSC was designed.The relation between the control parameters of TCSC′s damping control and the oscillation modes in power system was discussed later.Eigenvalue analysis and non linear simulation demonstrated that the developed method is very effective.
