Abstract :
This paper presents the nonlinear model of transformer which is based on Hammerstein method and describes the procedure of the parameter identification for the suggested model. In this procedure, a point slope parameterization of the static nonlinearity has been used which results in a computationally tractable optimization problem. The identification method simultaneously approximates the linear dynamic and nonlinear static blocks of the Hammerstein method.
