A transient damping method (TDM), introducing the frequency of a virtual synchronous generator through a high-pass filter (HPF) to the power reference, is usually adopted to stabilize the system against disturbances. However, different from a small-signal stability perspective, this letter reveals that the gain of HPF should not be too large due to the transient stability issues. Thus, an optimal parameter design method of the TDM is proposed for the improvement of transient stability. The experimental results validate the theoretical findings.

增强暂态稳定性的虚拟同步发电机优化阻尼设计


通常采用瞬态阻尼方法（TDM），通过高通滤波器（HPF）将虚拟同步发电机的频率引入功率参考，以稳定系统免受干扰。然而，与小信号稳定性的角度不同，这封信揭示了由于瞬态稳定性问题，HPF 的增益不应该太大。因此，提出了一种TDM的优化参数设计方法来提高暂态稳定性。实验结果验证了理论结果。
