POWER SYSTEM DIAGRAM PREPARING EQUIPMENT

PURPOSE: To prepare semiautomatically a power system diagram which has a geographic meaning, using power system information which is distributed in open market. CONSTITUTION: In a power system diagram preparing equipment 11, power system information is input from a node information storing equipment 12 and a branch information storing equipment 13 and a basic system diagram stored in a basic system diagram storing equipment 11d and a map stored in a map storing equipment 11e support a symbol position editing means 11a and help it determine positions of symbols and then prepare a power system diagram. The prepared diagram is stored in a power system diagram storing means 11f. Thus, the diagram prepared by this equipment includes positional information about nodes and branches. By using this equipment, a power system diagram which has a geographic meaning can be prepared easily.
