As the proportion of new energy power plants increases, in order to meet the stability requirements of the system, new energy plants must provide reactive power support and be equipped with static var generators (SVGs). Traditional single voltage sag research is difficult to characterize the applicability of control parameter identification. In order to obtain more accurate SVG model parameters to meet the requirements of safe and stable operation of doubly fed wind farm grid connected systems, a parameter identification method for SVG control model based on improved Archimedean optimization algorithm is proposed. Firstly, the electromechanical transient characteristics of SVG are derived in detail and its mathematical model is established on the Digsilent/factory platform. Then, the cascading fault voltage crossing test data of SVG is obtained in an actual doubly fed wind farm. Finally, a parameter identification method based on considering cascading faults is proposed based on the dynamic characteristics of SVG. Comparing simulation data with test data, the results show that the proposed identification method can effectively improve the identification accuracy of SVG control parameters. %K 静止无功发生器， %K 双馈风电场， %K 改进的阿基米德优化算法， %K 连锁故障， %K 参数辨识
