Abstract

The new 3-phase load flow program, which will be used for the steady state initialization of the real-time electromagnetic transient simulator developed by Mitsubishi Electric Co., is described in this paper. The program uses the standard models and input file of the well-known EMTP, converts these 3-phase models into its equivalent 1 phase model. In order to have a better convergence for large scale power system simulation, it uses the Newton-Raphson algorithm instead of the Gauss-Seidal algorithm for 3-phase load flow calculation. The EMTP benchmarks and IEEE 14, 57, 118 bus load flow test systems have been used to test the proposed program in both balanced and unbalanced condition
