【Abstract】 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.更多还原
