摘　　要：运用复转矩系数法与特征根法,对位于高压直流输电系统(HVDC)整流侧的汽轮发电机组的次同步振荡(SSO)特性进行了研究。对整流站控制与逆变站控制对汽轮发电机组的电气阻尼特性的影响进行了详细分析。研究表明,不同的控制方式与运行条件对次同步振荡特性的影响有显著差别。With complex torque coefficient method and eigenvalue method, the subsynchronous oscillation (SSO) characteristics of a turbine-generator set which is located at the rectifier side of a HVDC system is studied in this paper. The impact of the rectifier control and inverter control on the electric damping characteristics of the turbine-generator set is analyzed in detail. The results reveal that different control modes and operational conditions have remarkably different impace on SSO characteristics.
