论文摘要
在本文中，提出了一种基于广泛的面积测量系统（WAMS）的方法来估计具有集成电压源转换器（VSC）的AC系统的系统状态矩阵并识别机电模式。所提出的方法纯粹是无模型的，不需要准确的网络拓扑和系统参数。具有集成VSC的IEEE 68-BUS系统中的数值研究表明，所提出的基于测量的方法可以准确识别机电模式并估计阻尼比，模式形状和参与因子。这项工作可能是将来使用VSC开发基于WAMS的阻尼控制控制的基础。
In this paper, a wide-area measurement system (WAMS)-based method is proposed to estimate the system state matrix for AC system with integrated voltage source converters (VSCs) and identify the electromechanical modes. The proposed method is purely model-free, requiring no knowledge of accurate network topology and system parameters. Numerical studies in the IEEE 68-bus system with integrated VSCs show that the proposed measurementbased method can accurately identify the electromechanical modes and estimate the damping ratios, the mode shapes, and the participation factors. The work may serve as a basis for developing WAMS-based damping control using VSCs in the future.
