A hysteresis model is presented in this paper for electromagnetic transient analysis of power system network involving ferromagnetic elements. The major hysteresis loop is represented analytically and the minor hysteresis loops can be created automatically in terms of a displacement varying with nonlinearity. The transient behaviour of magnetizing branches is described by a set of nonlinear differential equations and an efficient numerical method is chosen to solve these equations. A comparison is also made ‘between the computed and experimental result. |
