Abstract

A modeling system and modeling method based on a logical relation, including 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 includes a graph increment calculating unit and a model increment calculating unit. The system, through description of the logical relation and based on support of the automatic wiring technology, realizes the graph-model integrated generation of a new grid model of the power system which is based on the description of the logical relation; the grid model is completely defined and modified on “one net”, which is different from the original way that the power system model is established on countless net graphs, thereby helping the grid operation manager to accurately and rapidly establish and modify the grid model of the full system.
