A NEW SYMBOLIC ANALYSIS APPROACH TO THE DC LOAD FLOW METHOD

A new symbolic analysis approach is proposed to the DC load flow metho d. The power system network parameters are given by symbols and the sy stem active line power Hows are derived analytically as closed-form sy mbolic expressions. An original program SALF is presented as a univers al tool to find the line powers by an automated computer-aided algorit hm. The theory of the DC load flow method is reviewed. The approach is illustrated by standard network examples. The approach exposed is tar geted at researchers and experts dealing with analysis, planning and o peration of transmission power system networks. (C) 1997 Elsevier Scie nce S.A.
