Abstract

The invention discloses a modeling system based on a logical relationship, which comprises an operation task integrating module, a task interpreter, a graph layout correcting module, a graph wiring correcting module and a database model increment correcting module, wherein the database model increment correcting module comprises a graph increment calculating unit and a model increment calculatingunit. Furthermore, the invention discloses a modeling method using the modeling system. The system, through description of the logical relationship and based on support of the automatic wiring technology, realizes the pattern-model integrated generation of a new grid model of the power system which is based on the logical relationship description; the grid model is completely defined and modifiedon one net, which is different from the original way that the power system model is built on countless net patterns, thereby achieving and helping the grid operation manager to accurately and rapidlyestablish and modify the grid model of the full system; and the modeling system is clear and direct, reliable and accurate, and is easy.

Description

technical field [0001] The invention relates to the field of electric power grid model construction, in particular to a modeling system and modeling method based on logical relations. Background technique [0002] The power grid model is the basis of all power system-related analysis, decision-making and management. Whether the model exists, whether it is complete, whether it is accurate, and whether it is easy to build should be said to be very important. It is to draw a picture first, then generate a model, and then write it into a relational database. The drawing is drawn by hand, using the method based on physical nodes, and each device object has one or more joint points, and the topology description is realized by drawing the connecting lines between the joint points; the scope of graphic drawing is usually based on the plant and station graphics As a unit, the connection relationship between stations is established through lines, thereby generating the power grid mod...
