The purpose of source end maintenance is to maintain data at a station end and realize the sharing of the whole network. During maintenance, substation information needs to be configured in an integrated configuration tool, a total station System Configuration (SCD) or System Specification (SSD) file is generated and imported into a plant end background system, a model, a main wiring diagram and an association relation are established, information monitoring is realized, and a plant end background uploads required data according to a master station scheduling requirement, so that the consistency of the whole data source is realized.
The source maintenance mainly refers to the maintenance of a data model, a network topology and a main wiring diagram. The main wiring diagram of the transformer substation refers to graphical representation of topological relations and operation states among elements of the transformer substation, and is widely applied to management, analysis and calculation of a power system, so that maintenance of the main wiring diagram is an important part of source end maintenance.

Although the enterprise logo expands the element attributes and introduces the length, width, rotation angle and coordinates of the primitive, the definition and naming mode of the primitive are not described in detail.
At present, each manufacturer adopts an expression mode of element attribute extension definition to realize detailed description of transformer substation information, but the interconnection and intercommunication of main wiring diagrams between manufacturers still have problems due to different primitive designs and implementation modes, so that a main wiring diagram interoperation method needs to be researched, and the method aims to overcome the defect that the main wiring diagrams cannot be automatically displayed due to different element definitions between manufacturers, so that interoperations such as automatic drawing of the main wiring diagrams, establishment of a primary and secondary equipment association relationship, generation of main station configuration and uploading are realized.

In order to realize the conversion of non-standardized primitives and the redefinition of primitive conversion strategies, a background predefines standard primitive extension attributes on the basis of drawing extension attributes (corresponding to the setting of the primitive extension attributes of primary equipment elements in a model file) defined in table 1, and simultaneously, all integer types are replaced by floating point types for drawing extension attribute types compatible with main wiring diagrams of various manufacturers, and the specific definition of the standard primitive extension attributes is shown in table 2. The predefined standard primitive extension attribute and the primitive extension attribute set by the model file for the primary equipment element jointly form a background primitive extension attribute.

The method comprises the following steps: if the imported model file is judged to be the SCD file, model data after SAX analysis is built in a background database or the put-in model data is updated; and if the imported model file is judged to be the SSD file, comparing whether the model data analyzed by the SAX is matched with the model data which is stored in the storage, and if so, updating the stored model data in a covering manner.
And 3, judging whether the primary equipment element in the current transformer substation information is in standard configuration or not by the background primitive extension attribute. Firstly, traversing primary equipment elements in current transformer substation information, and extracting a primitive extension attribute symbol _ org set for the primary equipment elements by a model file; then, based on the mapping relationship between the primitive extension attribute symbol _ org marked by the standard primitive extension attribute and the primitive in the standard primitive library, whether the primitive is the primitive in the standard primitive library is judged. If all the primitives of the primary equipment elements in the current transformer substation information are the primitives in the standard primitive library, judging that the current transformer substation information is in standard configuration, and directly performing the step 5; and (4) if the primitive of at least one primary equipment element in the current transformer substation information is not the primitive in the standard primitive library, judging that the current transformer substation information is not standard configuration, performing step 4, selecting a primitive conversion strategy, converting the transformer substation information into the standard configuration, and preparing for automatically drawing a main wiring diagram by a background.
And 4, if the current transformer substation information is in non-standard configuration, realizing the standardized conversion of the transformer substation information. The main process is as follows: firstly, traversing primary equipment elements in current transformer substation information, and extracting primitive extension attributes set for the primary equipment elements by a model file; and then, mapping the primitive of the primary equipment element in the current substation information into the primitive in the standard primitive library according to a preset primitive conversion strategy based on the mapping relation between the primitive extension attribute marked by the standard primitive extension attribute and the primitive in the standard primitive library. The specific contents are as follows:
(1) primary equipment element standardization conversion: traversing the equipment elements at intervals, mapping the non-standard primitives into standard primitives according to a primitive conversion strategy, and updating the extended attributes of the standard primitives;
(2) updating primary device element primitive relative coordinates to absolute coordinates: according to the enterprise logo definition, the upper left point coordinate in the primitive extension attribute is a coordinate relative to the original point of the upper left point coordinate system of the upper element, in the process of automatically generating the main wiring diagram, the transformer substation coordinate is defined as the original point (0, 0) of the canvas, and according to the transformer substation information structure, the voltage grade, the interval and the primary equipment element primitive coordinate are updated layer by layer as absolute coordinates relative to the transformer substation coordinate.
The primary equipment component standardization conversion method is described in detail below. In the embodiment, six primitive conversion strategies are provided, and the flow of primitive conversion in the six primitive conversion strategies is the same, as shown in fig. 2, which is a schematic flow chart of primitive conversion in the embodiment of the method of the present invention, and the specific method is as follows:
(1) and acquiring a standard primitive mapping object of the same type as the primary equipment element from a standard primitive library: if the primary equipment element belongs to a reduced equipment object, searching a corresponding standard primitive in a standard primitive library according to the type attribute type of the primary equipment element; if the primary equipment element belongs to a PowerTransformer transformer object, determining that the primary equipment element is a two-turn or 3-turn transformer or other transformers according to the number of transformerwining objects of a transformer winding, and acquiring corresponding standard primitives from a standard primitive library;
(2) when the primary equipment element belongs to the reduced equipment object, processing the primitive extension attribute rotate _ org to obtain a rotation interval flag rotate _ range and a rotation angle flag rotate _ angle. Fig. 3 is a schematic flow chart of the rotation angle processing in the embodiment of the method of the present invention, and the specific method is as follows:
1) when the rotate _ org is less than 0, circularly performing the operation of rotate _ org being equal to rotate _ org +360 until the rotate _ org being equal to 0, and converting the anticlockwise rotation angle into the clockwise rotation angle;
2) when the rotate _ org > is 360, circularly performing the rotate _ org-360 operation until the rotate _ org < 360;
3) calculating a rotation interval mark rotate _ range in which the rotation angle rotate _ org is located, wherein rotate _ range is rotate _ org/90, and acquiring a rotation angle mark rotate _ angle according to the rotation interval mark, wherein rotate _ angle is rotate _ range 90;
4) when the rotation angle is not more than 45 away from the next interval, the rotation interval flag is assigned as the next interval value, and the rotation angle flag is updated, that is, when rotate _ org% 90> is 45, rotate _ range +1 and rotate _ angle _ range 90.
(3) Processing the primitive extension attributes of the primary equipment elements and updating the values of the primitive extension attributes;
(4) and processing the endpoint of the primitive.
The six primitive conversion strategies are mainly distinguished by primitive extension attribute and endpoint processing methods:
(1) in the aspect of processing the primitive extension attributes, firstly, a factory-customized primitive is mapped to a standard primitive according to a primitive conversion strategy, and the primitive extension attributes are updated. The IEC61850 standard defines about 25 kinds of primary devices, such as circuit breakers, disconnectors, voltage/current transformers, transformer windings, etc., and each type of primary device is specifically divided into many subtypes, such as circuit breakers including standard circuit breakers, circuit breaker trolleys, etc., only the device type where the primitive is located can be located through the type attribute of the primary device element, and the primitive cannot be mapped to a specific primitive, so that the background standard primitive library covers all types of primitives, groups each type of standard primitive under the conditions of the number of non-ground terminals and the number of ground terminals, and assigns a default standard primitive for each group. Therefore, the mapping process from the factory customized primitive to the standard primitive is as follows: and searching the equipment type where the mapping standard primitive is located in the standard primitive library according to the primary equipment type, and positioning the group where the mapping standard primitive is located according to the number of non-grounding end points and the number of grounding end points of a factory customized primitive, wherein the default standard primitive of the group is the mapping standard primitive. And after the background main wiring diagram is automatically generated, checking the main wiring diagram according to the drawing, and updating the default primitive which does not conform to the design in the main wiring diagram to the correct primitive of the same sub-type group, so that the accurate mapping from the non-standardized primitive to the standard primitive is realized.
(2) In the aspect of primitive endpoint processing, primitives mostly have one or two endpoints, for a primitive with one endpoint, the problem of relative position of the endpoints does not exist, processing is not needed, and for primitives with two endpoints, the processing modes of relative positions of manufacturers are different. Thus, the processing of primitive endpoints actually refers to the processing of the relative positions of the endpoints of primitives with two endpoints (except for the transformer), and the other primitive endpoints are processed by the default endpoint method specified by the standard primitive. Primitive endpoint designations are defined as T1, T2, T3 …, based on the logo. This is true for the primitive endpoint processing that occurs below.
In this embodiment, the above six primitive transformation strategies are introduced as follows:
(1) primitive conversion strategy 1: and mapping the primitive to a standard primitive according to the primary equipment element type attribute type, the primitive extension attribute height _ org and the width _ org, and updating the primitive extension attribute, wherein the current primitive is a rotated primitive, and the endpoint of the primitive adopts a default value. FIG. 4 is a schematic diagram of the primitive processing flow of the primitive transformation strategies 1 and 2 in the embodiment of the method of the present invention, wherein widthstd、heightstd、symbolstd、rotatestdExtend attribute information, rotate, for primitives in a standard primitive librarystdDefault to 0, and the following appearance attributes all do. The specific method comprises the following steps:

2) And calculating the primitive extension attributes width, height and rotate, wherein the formula is as follows:
3) primitive coordinates xpos _ org and ypos _ org are set.
For a primitive with two endpoints, the relative position of the endpoint of the primitive adopts a default value, and the processing method comprises the following steps: the end positions are arranged left and right, the left side is T1, the right side is T2, the end positions are arranged up and down, the upper side is T1, and the lower side is T2.
(2) Primitive conversion strategy 2: and mapping the primitive to a standard primitive according to the primary equipment element type attribute type, the primitive extension attribute height _ org and the width _ org, and updating the primitive extension attribute, wherein the current primitive is a rotated primitive, and the endpoint of the primitive is changed along with the rotation interval mark rotate _ range. The primitive conversion strategy 2 and the primitive conversion strategy 1 have the same flow except that the primitive endpoint processing mode is different, and the specific method comprises the following steps:
1) the endpoint positions of the primitive after rotation are set up from top to bottom, when rotate _ range is 0 or 1, the upside is T1, the downside is T2, otherwise, the upside is T2, the downside is T1;
2) the endpoint positions of the primitive after rotation are set left and right, when rotate _ range is 0 or 3, the left side is T1, the right side is T2, otherwise, the left side is T2, and the right side is T1.
(3) Primitive conversion strategy 3: and mapping the primitive to a standard primitive according to the primary equipment element type attribute type, the primitive extension attribute height _ org, the width _ org and the rotation angle mark rotate _ angle, updating the primitive extension attribute, wherein the current primitive is a primitive before rotation, the coordinate of the upper left point of the primitive is changed along with the rotation angle mark rotate _ angle, and the endpoint of the primitive adopts a default value. As shown in fig. 5, it is a schematic diagram of primitive processing flows of primitive conversion strategies 3, 4, 5, and 6 in the embodiment of the method of the present invention, and the specific method is as follows:
1) mapping the primitive to the default primitive of the same type in the current standard primitive library according to the primary equipment element type and the primitive endpoint, and updating the primitive extension attribute symbol (symbol)std；
2) Calculating primitive extension attributes width, height and rotate, wherein the width and height calculation formulas are the same as the strategy 1, and the rotate calculation formula is as follows:
3)and calculating the coordinates xpos and ypos of the primitive. The standard primitive after primitive mapping is used for surrounding the central point (x) of the primitive graphic element rectangle0,y0) And rotating theta (theta), and changing the coordinates of the upper left point of the mapping standard primitive after rotation, wherein the specific formula is as follows:
mapping standard primitive upper left point coordinate with central point (x)0,y0) The coordinates (x, y) after rotation by θ are:
the rotation interval rotate _ angle includes 4, and from the value of θ in each interval, the calculation formula of (x, y) is as follows:
when rotate _ range is 0:
when rotate _ range is 1:
when rotate _ range is 2:
when rotate _ range is 3:
from the coordinates (x, y), the coordinates (xpos, ypos) of the top left point of the standard primitive mapped after rotation can be derived, and the calculation formula is as follows:
when rotate _ range is 0:
when rotate _ range is 1:
when rotate _ range is 2:
when rotate _ range is 3:
for a primitive with two endpoints, the relative position of the endpoint of the primitive adopts a default value, and the processing method comprises the following steps: the end positions are arranged left and right, the left side is T1, the right side is T2, the end positions are arranged up and down, the upper side is T1, and the lower side is T2.
