摘　　要：针对大规模区域互联电力系统,推导了适合于阻尼转矩分析法应用于大规模电网的全系统统一线性化模型,该模型可以统一多种控制器模型并有效整合至系统模型。在此基础上推导大规模电力系统阻尼转矩分析法计算过程,通过阻尼转矩通道、输出量重构、灵敏度指标求取过程的假设或简化,使得计算方法简单清晰,更容易推广至大规模电网的计算。最后推广至实际大规模电网计算,并且应用于直流控制器、电力系统稳定器的分析,均取得了可行有效的结果,证明了该方法应用于大电网的可行性和准确性。The Dynamic Torque Analysis method（DTA） is applied to large scale power system via uniform linear modeling which can be integrated into system model with various kinds of controllers.Then the calculation process of DTA is proposed,and via some simplifications and assumptions on the channel of damping torque,the reconstruction of output and the extraction of sensitivity,the calculation method is simpler and clearer,which can be more easily extended to the calculation of large scale power system.Finally,the proposed DTA is extended to practical large-scale grid calculation and also applied to the analysis of HVDC and PSS controllers,and the effective results are obtained,which proves the feasibility and accuracy of the DTA algorithm applied extended to large scale power system.
