Virtual terminal assisted automatic design method based on equipment encoding

Abstract

The invention discloses a virtual terminal assisted automatic design method based on equipment encoding.An input virtual terminal set and an output virtual terminal set of a to-be-designed device are constructed; relevance pairs composed of receiving devices and transmitting devices in SCD template files and virtual connection sets of the relevance pairs are constructed; relevance pairs of the current to-be-designed device are generated; a template relevance pair the same as encodes of the receiving device and the sending device of a current to-be-designed relevance pair is found out; all template virtual connection in a template virtual connection set of the template relevance pair is processed one by one; a corresponding template relevance pair, with the largest connection number, of a temporary virtual connection set serves as a best match target relevance pair of the current to-be-designed relevance pair, virtual connection meeting the filtering condition is added into an automatically-generated virtual connection set of the current to-be-designed relevance pair; processing continues on a next to-be-designed relevance pair till all current to-be-designed relevance pairs are processed, workloads are reduced, and the intelligent degree, accuracy rate and work efficiency of virtual terminal design are improved.

Description

technical field [0001] The invention relates to the fields of design, debugging, operation and maintenance of intelligent substations, in particular to an auxiliary automatic design method for virtual terminals based on equipment coding. Background technique [0002] At present, domestic design institutes mainly use the virtual terminal table (Excel file) to describe the virtual terminal connection between each device in the design of the SCD virtual terminal of the smart substation. The designers of the design institute design the virtual terminal connection table according to the main wiring of the whole station and the relay protection logic connection between each device. The virtual terminal table file generally includes virtual connections between devices, and each virtual connection includes: receiving device, input virtual terminal description, input virtual terminal reference, design description, output virtual terminal description, output virtual terminal reference...
