Time-domain based steady-state initialization for the EMTP

University of British Columbia

The existing steady-state initialization algorithm in the electromagnetic transients program EMTP is based on a frequency-domain admittance method. This yields a simple, efficient solution for linear, lumped element networks. However, the basic algorithm cannot be easily extended to handle nonlinear and variable structure networks. A time-domain based steady-state initialization algorithm is formulated for the three classes of lumped element networks, namely, linear, nonlinear and variable structure. The primary contribution of this work is that each network element does not require a dedicated steady-state model and a separate steady-state solution algorithm. Furthermore, as the proposed initialization process is consistent with the time-domain character of the transient simulations themselves, the proposed algorithm can be incorporated into existing electromagnetic transient programs with minimal programming effort.
