A Method of Realizing Model Interchange of Smart Devices Based on Semantic Matching

Abstract

The invention discloses a method for realizing intelligent device model interchange based on semantic matching, which comprises the following steps of: 1, establishing a semantic base of an intelligent device virtual terminal in a system database; 2, defining an application scene according to design specifications and networking modes, wherein the defined application scene has a scene name, and at least one intelligent device type model is defined in each application scene; and 3, completing a secondary system loop design by using the intelligent device type model in the step 2. According to the invention, a secondary system is designed on the basis of the type model, and a means for reaching a design depth of the secondary system at an initially-designing stage is provided for a designing institute so that the initially-designing scheme is more accurate and the designing institute conveniently proposes a performance index requirement of a purchasing device. In addition, in a process of operating a transformer substation, the conditions of frequently changing manufacturers and types or upgrading software versions of an intelligent device usually occur, thus the scheme can conveniently realize the device mode interchange.

Description

technical field [0001] The invention relates to a method for realizing intelligent device model exchange based on semantic matching. Background technique [0002] The current problems faced by smart substation design: [0003] 1) In the preliminary design stage of the substation, it is necessary for the design institute to provide a list of the functions and performance indicators of the smart devices and the materials used for communication equipment such as cables and optical cables. If the preliminary design depth is not enough, it is difficult to give these information more accurately. [0004] 2) Even at the stage of construction drawing design, the manufacturer's ICD document cannot be provided, or the version of the provided ICD document changes frequently, and the change of ICD document will lead to the change of the model file and the secondary circuit. [0005] 3) Since the secondary circuits of substations with the same voltage level and similar design schemes ar...

AI Technical Summary

Problems solved by technology

[0003] 1) In the preliminary design stage of the substation, the design institute needs to provide an inventory of the functions and performance indicators of the smart device, and the cables and optical cables of the communication equipment. If the depth of the preliminary design is not enough, it is difficult to give these information more accurately

[0004] 2) Even at the stage of construction drawing design, the manufacturer’s ICD document cannot be provided, or the version of the provided ICD document changes frequently, and changes in the ICD document will lead to changes in the model file and the secondary circuit

However, if the smart substation is designed directly based on ICD documents, it is difficult to complete the design based on engineering similarity
