Abstract

Design of a mine electric power system requires that power- flow studies be conducted to guarantee that all motor operating and starting loads can be met while maintaining acceptable bus voltage levels. If future loads are overestimated, then the iterative techniques used to solve for the system voltage profile will often diverge, leaving no clue for the designer as to the cause of the divergence. A nondiverging power-flow formulation based upon Newton's method is presented which is applicable to power-flow programs that use the polar form of the bus voltage variables. The method is effective in guaranteeing nondivergence of the power-flow solution and in providing an indication of where erroneous system data exists for nonconvergent cases.
