Nonlinear elements in the EMTP: steady-state initialization

A methodology is presented for the formulation and solution of power networks containing a class of nonlinear elements within the framework of electromagnetic transient programs. The method facilitates steady-state initialization formulated in the time-domain as a two-point boundary value problem. T...

Zusammenfassung:A methodology is presented for the formulation and solution of power networks containing a class of nonlinear elements within the framework of electromagnetic transient programs. The method facilitates steady-state initialization formulated in the time-domain as a two-point boundary value problem. The techniques developed are applied to a simple power network exhibiting harmonics due to transformer saturation.< >
