Abstract The parameter identification of equivalent circuit model for XLPE power cable insulation is critical to evaluate the aging status of XLPE insulation. To avoid the limitations of the existing methods, this paper presents a new approach based on stabilization diagram and SSM algorithm to calculate the parameters of extended Debye equivalent circuit model. Firstly, the stabilization diagram is created by the depolarization current data through SSM algorithm. Then, the number of relaxation branches is determined by the number of stability axis. Finally, the unique parameters of the equivalent circuit can be accurately calculated by SSM. The results of simulation show that the method has strong anti-noise ability and high accuracy, and overcomes the problems of traditional methods. Case study verifies the feasibility and effectiveness of the proposed method.

Key words： Depolarization current extended Debye model stabilization diagram state space model (SSM) parameter calculation
