The rapid power development in the modern world put increasingly before science complex tasks. Their decision must he visible and accessible to understand. One of the energy problems is the problem of electrical synthesis networks. Electrical networks are like human nervous system, i.e. they have complicated structure functioning. Besides networks, especially of large power systems, cover whole regions, it means that the topology of networks is very complicated. Analyzing modes of power, first of all it is necessary to know its scheme. The scheme includes generate nodes, consumption nodes and power lines. To get scheme or graphic representation of its spatial location on the ground, it is advisable to use a computer program - graphics editor. The graphical editor allows to visualize the process of constructing the electric network scheme and to accelerate the process of analysis. The basis of the graphical editor - graph theory and wave algorithm Lee. Wave algorithm may be implemented using a computer program. The algorithm is based on minimal topological information: list of branches, nodes' numbers. The idea is as follows. Knowing the minimum information about the nodes and branches of the system, it is necessary to determine the central node and four supporting peripheral nodes, located on either side of Light. Then, considering these nodes fixed, begins an iterative process - specifies the location of other nodes. Thus, the editor, based on the wave algorithm Lee, visualizes the process of constructing the scheme of the electrical network, which facilitates further analysis of this system.
