To address the excessive time consumption and computational burden in the electromagnetic transient simulations of large-scale doubly-fed wind farms, this study proposes a fault transient equivalent modeling method based on the dynamic response characteristics of DC bus voltage. By analyzing the dynamic response curve of DC bus voltage, the method effectively characterizes the protection status of Crowbar and Chopper circuits while simultaneously reflecting fluctuations in terminal voltage and wind speed variations. Building on this foundation, an improved K-means algorithm is adopted for wind turbine clustering, establishing a fault transient equivalent model for doubly-fed wind farms. Case studies demonstrate that the proposed model achieves higher accuracy in simulating detailed doubly-fed wind farms.
