| Abstract: | Algorithm of fault simulation and fault location for distributed line model, starting from the fundamental equations of long line, is systematically put out in the paper. Comparison with EMTP is done. The discrepencies between the steady state components of bus voltage and line current calculated by "lumped resistance line model" used in EMTP and those by "distributed rLC line model" proposed here are shown with numerical examples. Where the main difference in which gives rise to the discrepencies is also pointed out. |
