A method for automatic generation of network connection diagrams of intelligent substation process layer

Abstract

The invention discloses a method for automatically generating a process-level network connection graph of an intelligent substation. The method comprises the steps of firstly, setting a style templateof the process-level network connection graph, wherein graphic element objects in the style template are used for formulating a representation form and a generated rule during instantiation; and selecting a voltage grade and a A / B network parameter; then cloning from an image of the style template to establish a new image, analyzing and recording a graphic template object in the new image, acquiring setting information for automatic drawing, and establishing a hierarchical relation of a drawing template object; acquiring the hierarchical relation of the process-level network connection, and calculating layout information of each layer; sequentially calculating a top layout of each central switch from left to right to generate a network line between the central switches; cloning accordingto the drawing template object to generate the graphic element objects, port objects and connection line objects of all secondary equipment, and establishing an association between an object ID (Identification) and a drawing object; and storing the image. The method can be applied to monitoring of a visual state of the secondary equipment in a relay protection operation and maintenance system of the intelligent substation.

Description

technical field [0001] The invention belongs to the field of power systems, and relates to a method for generating a process layer network connection diagram in an intelligent substation relay protection operation and maintenance system, in particular to a method for automatically generating a process layer network connection diagram based on substation relay protection SCD model information. Background technique [0002] With the promotion and application of smart substations, the operation and maintenance mode of relay protection has undergone revolutionary changes. The traditional substation operation and maintenance management system can no longer meet the needs of smart substations. The operation and maintenance of smart substation relay protection is facing huge challenges. The specific performance is as follows: The following aspects: the physical real terminal becomes a virtual terminal, and the secondary circuit is invisible and intangible; the cable becomes an optic...
