ResumoNonlinear branches, such as saturable reactors, can generate harmonics and consequently increase the EMTP time-domain simulation time before the actual distorted steady-state is reached. This is an important initialization problem for transient analysis studies performed in steady-state operating conditions. This paper presents the implementation of a new method in the EMTP for initializing time-domain simulations. It is based on frequency domain steady-state calculations including harmonics from nonlinear branch functions. >
