Abstract Ensuring stability in transient simulations of power systems requires that intrinsically passive components of the network should be represented with passive models, including transmission lines and cables. Existing research on passivity enforcement of the wideband line or cable model is based on the perturbation of residues of the state-space model of the characteristic admittance, ignoring its poles and its constant term. This paper presents the advantages and limitations of including the poles and constant matrix of the characteristic admittance in the passivity enforcement method of wideband models.

通过残基和极点的耦合扰动增强宽带线路模型的无源性

摘要 为了确保电力系统瞬态仿真的稳定性，网络固有的无源组件应该用无源模型表示，包括传输线和电缆。现有关于宽带线路或电缆模型的无源增强的研究是基于特征导纳的状态空间模型的残差的扰动，忽略了它的极点和常数项。本文介绍了在宽带模型的无源强制方法中包含特征导纳的极点和常数矩阵的优点和局限性。
