Description
Technical Field
The invention relates to a generation method of an SSD file of a transformer substation, and belongs to the technical field of relay protection of power systems.
Background
The substation configuration language (Substation Configuration Language, SCL) is the foundation for realizing the intelligent station, and by using the SCL language to perform unified modeling on the system and equipment in the intelligent station, different service users can conveniently know the organization structure, the function distribution and the equipment functions and the accessible information model of the whole intelligent station system. SSD (System Specification Description) is a primary system specification description file of the intelligent station conforming to the SCL grammar, can describe a primary system structure, association of secondary equipment and the like, and has important roles in realizing automatic configuration and some advanced applications of the intelligent station. For example, the automatic configuration function of communication parameters and virtual terminal connection lines in the intelligent station can be realized through SSD, and the automatic generation of a system wiring diagram of a monitoring system and even a scheduling end can be realized.
Currently, research into SSDs is mainly focused on automatic mapping from SSD files, while less is involved in how to generate SSD files themselves. For example, chinese patent application documents with application publication numbers CN106933942a and CN106485599a respectively disclose a method for automatically mapping a primary system wiring described based on a substation specification and a method for visually displaying an SSD configuration file of an intelligent substation, which describe a method for displaying an SSD file in a graphic and tree structure respectively, but both the methods are based on existing SSD files and then visually displaying the SSD files, so as to achieve the effect of friendly interpretation of the SSD files, and how to generate the SSD files is not described.
Compared with visual display of SSD files, how to efficiently generate SSD files is a basic work, and the current method for generating SSD files depends on drawing tools or manually dragging moving elements, so that the generating efficiency of SSD files is low. For example, chinese patent document with grant bulletin number CN106055786B discloses a graphical SSD configuration method based on an IED template, which uses an IEC61850 model structure or a similar tree hierarchy structure as a data structure of an in-station library for a current intelligent substation, and includes graphical engineering configuration tools, first drawing primary devices and electrical connection relations thereof in the SSD, then drawing secondary device primitives in the substation by using primitive functions of the graphics tools, associating the secondary device primitives with corresponding models thereof to form an IED template, and further forming a template library of the IED. And finally, when carrying out secondary association of the SSD, directly carrying out the secondary association on primary equipment of the SSD and an electric connection graph thereof in a form of dragging the IED template, and ensuring intuitive and convenient configuration. However, the method still adopts a drawing tool to carry out configuration on the SSD configuration, mainly aims at improving the efficiency of the association of the primary equipment and the secondary equipment, and does not fundamentally improve the efficiency of SSD generation.

The beneficial effects of the invention are as follows: and generating an interval instance model file of all the main wiring modes of the transformer substation and corresponding interval maximizing equipment in advance through exhausting the main wiring modes of the transformer substation and the corresponding intervals. When an SSD file of a certain transformer substation is required to be generated, only the main wiring mode of the transformer substation and related interval equipment are required to be known, and the interval instance model file is modified, so that the SSD file can be quickly generated without concern about the position and the associated attribute of each equipment graphic element, and the generation efficiency of the SSD file is effectively improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
The embodiment provides a method for generating an SSD file of a transformer substation, and a corresponding flow chart is shown in FIG. 1, and the method comprises the following steps:
(1) And (5) exhausting all main wiring modes of the transformer substation and a plurality of interval information corresponding to each main wiring mode.
Based on the exhaustion of the main wiring mode and the interval of the transformer substation, the wiring mode and the interval division are relatively fixed, and all the main wiring modes of the transformer substation and corresponding multiple interval information can be acquired by referring to the existing method or according to engineering examples. For example, for a substation, a main wiring mode and information of a plurality of intervals corresponding to the main wiring mode are acquired.
(2) And constructing an interval instance model file according to all the main wiring modes of the transformer substation and a plurality of interval information corresponding to each main wiring mode.
Each interval instance model file is determined according to the corresponding interval type, the maximizing equipment of the interval and the main wiring mode of the interval. The interval instance model file herein refers to a model file described in SCL syntax that contains interval types and interval device maximization configurations, for example, an instance model file for a certain line interval is as follows:
(3) And acquiring a main wiring mode of the transformer substation for generating the SSD file and related interval equipment, searching a plurality of corresponding interval instance model files according to the main wiring mode, and modifying the interval instance model files according to the interval equipment on the basis of the searched interval instance model files to generate the SSD file.
When a certain transformer substation needs to generate an SSD file, the position and the associated attribute of each equipment graphic element are not required to be concerned, only the wiring mode of primary equipment and all interval and interval equipment are required to be provided, the interval instance model file generated in the step (2) is modified, and the modification process comprises combination and cutting, so that the SSD file is automatically generated. For example, for a primary device interval, the interval type and the primary device type included in the interval type are first determined, then the interval instance model file is matched, and the interval instance model is cut according to the device type in the primary device interval to generate a corresponding interval instance. Corresponding interval instances are generated for all primary device intervals in turn. And finally, combining all the interval examples according to the main wiring mode to generate a final SSD file.
Taking the generation of a 220kV high-voltage side SSD file as an example, the wiring mode of the high-voltage side of the station is double-master double-branch. Obtaining interval configuration under a double-parent double-tapping line mode according to an interval instance model file, for example: including transformer spacing, bus-tie spacing, and branch spacing, etc. And deleting the primary equipment in the interval instance model file according to the primary equipment configuration of the station, and combining all interval instance model files obtained after deletion into a double-parent double-divided SSD file.
Of course, in the above method for generating the SSD file of the substation, if the interval instance model file is already constructed before, that is, the existing interval instance model file is stored, then in the process of generating the SSD file of the substation, the first two steps are not needed, and the existing interval instance model file is directly utilized to generate the SSD file of the substation.
By the method for generating the SSD file of the transformer substation, the SSD file can be generated rapidly, and the problem of low efficiency in the current SSD configuration process is solved effectively.
