| 摘要: |
| 基于阻尼转矩分析（DTA）法，推导了适用于多广域阻尼控制器分析的全系统统一线性化模型；在此基础上提出多控制器多模态交互影响因子指标，该指标能清晰表征交互影响的方向性和定量性；提出模态总阻尼由设计阻尼和交互阻尼组成，分析了交互阻尼的影响机理；研究了考虑多控制器多模态交互影响因子的广域阻尼控制器的配置优化方法。算例结果表明交互影响在广域阻尼控制器配置过程中是必须考虑的重要因素，也证明了所提配置方法的正确性。 |

| Abstract: |
| The unified linear system model applicable to the analysis of multiple wide-area damping controllers is deduced based on DTA（Damping Torque Analysis） method and an indicator of multi-controller multi-modal interaction factor is proposed to clearly characterize the directivity and quantifiability of interaction. It is brought forward that the total modal damping is made up of the design damping and the interaction damping. The influencing mechanism of interaction damping is analyzed and the optimal configuration of wide-area damping controllers is proposed with the consideration of multi-controller multi-modal interaction factor. Case study shows the interaction factor must be considered in the configuration of wide-area damping controllers，which proves the correctness of the proposed configuration method. |
