A single line diagram of a power distribution network wide area measurement control System describes a topological connection relationship of power equipment, and is generally imported from a Geographic Information System (GIS) System in a Scalable Vector Graphics (SVG) file format. Due to different attention points of the system, the imported SVG file is often incomplete in measurement and annotation, and the measurement and annotation needs to be completed manually or by a program. For multi-source measurement, effective data sources are also identified and displayed in parallel; the manual labeling has the advantages that other primitives are rarely shielded, the repeated workload is large, and the arrangement is difficult to ensure to be neat due to the dynamic change of the number of effective data sources. The program labeling is just opposite, and the method has the advantages of small repeated workload, orderly arrangement of effective data sources and difficult avoidance of shielding; the simple way of program labeling is to add a predefined coordinate offset to the device location as the measurement labeling location.

The measurement graphic element group can comprise one or more measurement graphic elements, and the measurement graphic elements can be basic graphic elements such as points, lines, surfaces and the like in a single line diagram, and measurement targets, measurement labels and other information formed by combining the basic graphic elements. Therefore, by aiming at a plurality of data sources of the same measurement and aiming at the minimum weighted shielding area, the measurement marking position is automatically marked and optimized, the automatic marking of the multisource measurement on the single line diagram in the power distribution network wide area measurement control system is realized, the manual maintenance workload can be reduced, the neatness and attractiveness of the single line diagram are improved, the information comprehensiveness is ensured, the marking efficiency is improved, and the relevant information of the power equipment can be more accurately and comprehensively acquired in real time through the single line diagram.
Fig. 2 is a flowchart illustrating a labeling method for multi-source measurement in a wide-area measurement control system of a power distribution network according to an embodiment of the present disclosure; as shown in fig. 2, in a possible implementation manner, in step 10, the obtaining a measurement map tuple according to multi-source measurement information may include:

and 103, arranging the effective values to obtain the measurement map tuple.
In a possible implementation manner, in step 101, a real-time value of the multi-source measurement information is obtained, that is, a real-time value of each data source of the multi-source measurement is obtained; for example, the measurement target takes a 301 switch as an example, and the a-phase current measurement Ia of the 301 switch can obtain measurement Data of two Data sources in real time, one Data source is acquired by a D-PMU, and the other Data source is acquired by a Data Transfer Unit (DTU) and then forwarded by a DMS system; the real-time value of the D-PMU is 2.18A and the real-time value of the DMS is 2.2A by calling a real-time library interface.
In a possible implementation manner, in step 102, the obtaining a valid value by performing a validity decision on the real-time value includes: and carrying out validity judgment on the real-time value according to the power grid model and/or the state estimation result to obtain the valid value.
In the embodiment of the present disclosure, a power grid model and the obtained real-time values of the multi-source measurement information may be combined to perform state estimation, so that validity of each of the acquired real-time values is determined according to a state estimation result, and one or more real-time values determined to be valid are used as valid values. For example, validity may be determined by state estimation on the two real-time values 2.18A (D-PMU real-time value) and 2.2A (DMS real-time value) obtained in step 101, and in this embodiment, both real-time values 2.18A and 2.2A are determined to be valid by conventional state estimation.
In a possible implementation manner, in step 103, the arranging the valid values to obtain the metric map tuple includes: arranging the effective values according to a preset arrangement direction to obtain a first sequence; adding a measurement type prefix to the first sequence to obtain a second sequence; and obtaining the measurement pixel group by adjusting the font, the font size, the containing matrix size and the background color of the second sequence.
It should be noted that, in the embodiment of the present disclosure, the arrangement direction may be set and adjusted according to actual needs, for example, the arrangement direction may be from left to right, from right to left, from top to bottom, from bottom to top, and the like, which is not limited in this embodiment; meanwhile, the font size, the containing matrix size, the background color and the like can be adjusted and set according to actual needs, and the embodiment does not limit the setting.
For example, FIG. 3 is a schematic diagram illustrating a metrology primitive group structure according to an embodiment of the present disclosure; as shown in fig. 3, the two valid values (i.e. two valid real-time values) 2.18A and 2.2A obtained above are arranged from left to right to obtain a first sequence, and a measurement type prefix Ia is added in front of the first sequence to form a second sequence, and then a second sequence of english font Arial, number 12, can be set, and a graphical interface is invoked to obtain a minimum containing rectangle of the measurement tuple with a length of 80 pixels and a width of 12 pixels; the background of the D-PMU real-time values is set to green and the background of the DMS real-time values is set to blue, forming a metric map tuple.
Fig. 4 is a flowchart illustrating a labeling method for multi-source measurement in a wide-area measurement control system of a power distribution network according to an embodiment of the present disclosure; as shown in fig. 4, in a possible implementation manner, in step 20, the weighting the measurement primitive group on the occlusion area of other non-measurement primitives on the single line diagram, and determining the labeling position according to the obtained weighted value may include:
and 204, obtaining the marking position by selecting the minimum value in the weighted value.
In one possible implementation manner, in step 201, the selecting a plurality of candidate positions in the peripheral area of the metrology target includes: dividing the peripheral area of the measuring target into a plurality of sub-areas according to the preset position direction; and traversing each sub-region according to a preset interval based on the position of the measurement target to obtain a corresponding candidate position.
It should be noted that, in the embodiment of the present disclosure, the positions and the number of the sub-regions obtained by dividing the peripheral region of the measurement target may be set according to actual needs, which is not limited in this embodiment; meanwhile, the preset interval may be a certain number of pixels, such as 20 pixels, 10 pixels, 5 pixels, and the like, and the specific number of pixels may be adjusted and set according to actual needs, which is not limited in this embodiment.
For example, fig. 5 is a schematic diagram of a candidate annotation area according to an embodiment of the disclosure; as shown in fig. 5, the coordinates of the central point in the single line diagram of the measurement target (i.e. 301 switch in the diagram) may be used as a reference, four areas, namely, an upper area, a lower area, a left area and a right area, are selected, a preset interval is set to 10 pixels, and then, in the four areas, the upper area, the lower area, the left area and the right area, the areas are traversed by taking 10 pixels as increments, and each obtained coordinate point (X, Y) is used as a candidate marking position of the measurement pixel group;
in a possible implementation manner, in step 202, the occlusion area of the metric map tuple on other non-metric primitives on the single line map at each candidate position is obtained;
for example, in the above step, 10 pixels are used as an increment, 20 candidate positions (5 candidate positions in each direction area) are obtained by traversing the upper, lower, left and right areas, the measurement primitive group to be labeled is assumed to be sequentially labeled at each coordinate point of the 20 candidate positions, and the occlusion area of the measurement primitive group to other primitives in the single line diagram, that is, the area of the overlapping area of the measurement primitive group to be standard and other primitives in the single line diagram, is further obtained.
In a possible implementation manner, in step 203, a corresponding weighted value is obtained by performing weighting processing on the occlusion area;
for example, table 1 shows the weight of the occluded primitive, and as shown in table 1, the occlusion area weight of each candidate position relative to other primitives may be obtained according to the corresponding relationship between the preset primitive type and the occlusion area weight, so as to obtain the weighted value S of the occlusion area of all other primitives in the single line map by the measurement primitive group at each candidate position, that is, the occlusion area weighted values S1, S2, S3 … corresponding to different candidate positions may be obtained. It should be noted that the specific value of the occlusion area weight corresponding to different primitive types may be determined according to factors such as the importance of an actual primitive, and the like, which is not limited in this embodiment.
TABLE 1 weight of occluded primitives
In a possible implementation manner, in step 204, the obtaining the annotation position by selecting a minimum value of the weighted values includes: obtaining corresponding distance values by calculating the distance between the measurement map tuple and the measurement target at each candidate position; and determining the labeling position according to the distance value under the condition that the candidate position corresponding to the minimum value is not unique.
For example, searching for the minimum value in the occlusion area weighted sum S sequence (i.e., the weighted values S1, S2, S3 … corresponding to each candidate position), and then taking the candidate position corresponding to the minimum weighted value as the annotation position; and marking the measurement map tuple in the single line diagram according to the marking position.
Considering that there is a case where the candidate positions corresponding to the weighted values are not unique (i.e., the weighted values corresponding to at least two candidate positions are the same), in the embodiment of the present disclosure, by further calculating the distance L between the coordinate point (X, Y) and the measurement target, at least two candidate positions with the same weighted value are further filtered, so that the coordinate point (X, Y) corresponding to the minimum value of the distance L is used as the final labeled position.
For example, table 2 shows a recording table of different candidate position coordinates (X, Y), occlusion area weighting values S, and distances L; as shown in table 2, the minimum value in the sequence of the weighted sum S of the searched occlusion areas is 0, that is, the marked measurement has no occlusion to other primitives on the graph, and the corresponding coordinate points are (640, 350) and (640, 360), that is, the minimum value appears for a plurality of times, the value of the distance L is further compared, because the coordinate point (640, 350) is closer to the 301 switch (640, 300), the coordinate point (640, 350) is selected as the marking position of the final multi-source measurement, and then the measurement map tuple is marked in the single line graph according to the marking position.
