Abstract:
Calculations of steady-state modes of a complex electric power system are significantly simplified
if we use the coefficients of distribution of the setting currents. The use of the theory of directed graphs for
the formation of the matrix of the coefficients of distribution of the setting currents is directly related to the
determination of the values of all possible and specific trees of the graph of a complex electric network. The
authors have developed and implemented an improved algorithm. calculation of current distribution
coefficients of the electric power system. The concepts of the "base" of the graph and the "hanging" contour
are introduced. In this case, to calculate the current distribution coefficients, it is necessary to take into
account all possible and specific trees of only the graph base. A method is indicated for supplementing the
matrix of current distribution coefficients of the graph base to the current distribution matrix of the original
graph. The paper proposes methods for simplifying the network topology based on the development of
diacoptic principles.
