Embodiment Construction

[0012] The technical solution of the present invention will be described in further detail below according to the accompanying drawings.

[0013] SVG (scalable vector graphics) is a graphic format for describing two-dimensional vector graphics based on Extensible Markup Language (xml).

[0014] According to the basic rules of operation blocking between devices required for operation and operation error prevention, the present invention finds out interoperable blocking devices through topology search, does not rely on manual definition, and automatically adapts to changes in electrical equipment and power grid topology. The SVG primary wiring diagram of the substation contains information such as the type, coordinates, size, and shape of various primitives, as well as the color of each layer, text description, etc., and generates equipment node numbers through node storage. Firstly, all operating devices are screened out from these primitives, and then searched sequentially in ...

Abstract

The invention discloses a five-prevention interlocking topology analysis method based on a substation scalable vector graphics (SVG) primary connection diagram. The method is characterized by comprising the following steps: in the substation SVG primary connection diagram, setting two node numbers for switches and knife switches respectively, only one node number for an earthing knife switch and one node number for two connected devices, and forming topology connection relation files of devices; and searching devices related to each device through device node numbers generated by the SVG topology connection diagram to obtain states of devices related to an operation device, and generating five-prevention rules of the operation device according to device operation logic. According to the five-prevention interlocking topology analysis method, the devices related to each device is searched through device node numbers generated by the SVG topology connection diagram, and five-prevention rules of the operation device are generated through rules and states of devices related to the operation device, accordingly, various mis-operation accidents are effectively prevented.

Description

technical field [0001] The invention relates to a five-proof locking topology analysis method based on a substation SVG primary wiring diagram, belonging to the field of substation automation. Background technique [0002] After years of construction and promotion, the microcomputer error prevention system has achieved great results in preventing error operations, but the five prevention rules are artificially generated, which is time-consuming, laborious and error-prone. During the construction of the substation anti-error system, it is necessary to formulate the anti-error rules of the substation equipment in different operation modes in advance. This work is usually performed by professional technicians (electrical designers, technical personnel of five-proof manufacturers, and experienced substation personnel) operating personnel or five-defense full-time) to complete. When the scale of the substation is large, there are many operating equipment, and the operation mode ...
