摘　　要：对具有可控串联电容补偿的电力系统，提出了一种直接计算可控串补对次同步频率分量所反映出的等值阻抗的算法。基于该计算原理，对可控串补具有正等值电阻这一特性给出了详细的机理解释。This paper presents an algorithm for directly calculating the equivalent impedance of thyristor controlled seriescapacitor (TCSC) with respect to subsynchronous frequency components in power systems with TCSC. The results obtainedfrom a sample system by using the proposed algorithm show that the equivalent impedance of TCSC possesses significantpositive resistance property. Furthermore. a detailed mechanism explanation of the property'is given.
