Detailed Description
Various exemplary embodiments, features and aspects of the disclosure will be described in detail below with reference to the drawings. In the drawings, like reference numbers indicate identical or functionally similar elements. Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
In addition, numerous specific details are set forth in the following detailed description in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art have not been described in detail in order not to obscure the present disclosure.
The power distribution network wide area measurement control system D-WAMS is additionally provided with power distribution network synchronous phasor measurement devices (Distribution network-phasor measurement unit, D-PMU) based on a power distribution management system (Distribution management systems, DMS), and a multi-source information integration and multi-dimensional data analysis technology is introduced, so that the measurable, considerable and controllable level of the power distribution network is greatly improved.
A single line diagram of a wide area measurement control system of a power distribution network, describing the topological connection of power equipment, is generally imported from a geographic information system (Geographic Information System, GIS) in the format of a scalable vector graphics (Scalable Vector Graphics, SVG) file. Because of different focus points of the system, the imported SVG files often have incomplete measurement labels, and manual or program complement measurement labels are needed. For multi-source measurement, effective data sources are identified and displayed in parallel; the manual annotation has the advantages of less shielding of other primitives, large repeated workload and difficulty in ensuring the arrangement of the effective data sources due to the dynamic change of the number of the effective data sources. The program labeling is just opposite, so that the repeated workload is small, the effective data sources are orderly arranged, and the disadvantage is that shielding is difficult to avoid; the simple way of program labeling is to add a predefined coordinate offset to the device position as the measurement labeling position.
Therefore, the present disclosure provides an automatic labeling scheme for multi-source measurement in a wide area measurement control system of a power distribution network, wherein real-time values are respectively taken for a plurality of data sources of the same measurement, effective real-time values are arranged to be measurement primitive groups, coordinates are traversed in a certain area around a device to be labeled, and a position with the minimum weighted shielding area of the measurement primitive groups to other primitives is searched to be used as a labeling position, so that automatic labeling of multi-source measurement is realized.
Fig. 1 illustrates a flowchart of a method of labeling multi-source measurements in a wide-area measurement control system for a power distribution network according to an embodiment of the present disclosure. As shown in fig. 1, the method may include:
step 10, obtaining a measurement primitive group according to the multi-source measurement information;
step 20, weighting the shielding areas of other non-measurement primitives on the single line diagram by the measurement primitive group, and determining a labeling position according to the obtained weighting value;
step 30, marking the measurement primitive group in the single line diagram according to the marking position;
the multi-source measurement information is data of a plurality of data sources aiming at the same measurement target.
In the embodiment of the disclosure, the single line diagram is; based on the fact that three-phase power transmission mode is adopted in an actual power system, namely three wires are adopted to connect two nodes (three phases), the electric main wiring diagram is generally represented by a single-line diagram for clearly reflecting wiring conditions, namely three wires are connected between one wire representation. The measurement graphic primitive group can comprise one or more measurement graphic primitives, and the measurement graphic primitives can be basic graphic elements such as points, lines, planes and the like of a single line drawing, and the information such as measurement targets, measurement labels and the like formed by combining the basic graphic elements. Therefore, the measurement marking position is automatically marked and optimized by aiming at a plurality of data sources measured in the same way and taking the minimum weighted shielding area as a target, so that the automatic marking of the multi-source 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 uniformity and the attractiveness of the single line diagram are improved, the information comprehensiveness is ensured, the marking efficiency is improved, and the related information of the power equipment can be more accurately, real-time and comprehensively acquired through the single line diagram.
FIG. 2 illustrates a flow chart of a labeling method for multi-source measurements in a wide-area measurement control system for a power distribution network according to an embodiment of the disclosure; as shown in fig. 2, in a possible implementation, in step 10, the obtaining a measurement primitive group according to the multi-source measurement information may include:
step 101, acquiring a real-time value of the multi-source measurement information;
102, obtaining an effective value by carrying out effectiveness judgment on the real-time value;
step 103, arranging the effective values to obtain the measurement primitive group.
In one possible implementation, 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, taking a 301 switch as an example, the a-phase current of the 301 switch measures Ia, so as to obtain measurement data of two data sources in real time, wherein one data source is collected by a D-PMU, and the other data source is collected by a data transmission device (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 one possible implementation manner, in step 102, the obtaining a valid value by making 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 disclosure, the state estimation may be performed by combining the power grid model and the obtained real-time values of the multi-source measurement information, so as to determine the validity of each collected real-time value according to the state estimation result, thereby taking one or more real-time values determined to be valid as valid values. For example, the validity of the two real-time values 2.18A (D-PMU real-time value) and 2.2A (DMS real-time value) obtained in step 101 may be determined by state estimation, and in this embodiment, the two real-time values 2.18A and 2.2A are both valid values by conventional state estimation.
In one possible implementation, in step 103, the arranging the valid values to obtain the measurement primitive group includes: arranging the effective values according to a preset arrangement direction to obtain a first sequence; obtaining a second sequence by adding a measurement type prefix to the first sequence; and obtaining the measurement primitive group by adjusting the font, the font size, the inclusion 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 may be left to right, right to left, top to bottom, bottom to top, and the like, which is not limited in this embodiment; meanwhile, the font size, the inclusion matrix size, the background color, and the like can be adjusted and set according to actual needs, which is not limited in this embodiment.
For example, FIG. 3 illustrates a schematic diagram of a measurement primitive set according to an embodiment of the present disclosure; as shown in fig. 3, the two obtained effective values (i.e., two effective real-time values) 2.18A and 2.2A are arranged from left to right to obtain a first sequence, a measurement type prefix Ia is added in front of the first sequence to form a second sequence, then an english font Arial of the second sequence can be set, the number of the english font is No. 12, and a graphic interface is called to obtain a minimum-contained rectangle of the measurement primitive group 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, thereby forming a measurement primitive set.
FIG. 4 illustrates a flowchart of a method of labeling multi-source measurements in a wide-area measurement control system for a power distribution network, according to one embodiment of the disclosure; in a possible implementation manner, as shown in fig. 4, in step 20, the weighting the occlusion areas of the measurement primitive group on other non-measurement primitives on the single line diagram, and determining the labeling position according to the obtained weighting value may include:
step 201, selecting a plurality of candidate positions in a peripheral area of the measurement target;
step 202, obtaining the shielding areas of the measurement primitive group on other non-measurement primitives on the single line diagram at each candidate position;
step 203, obtaining a corresponding weighted value by weighting the shielding area;
and 204, obtaining the labeling position by selecting the minimum value in the weighted values.
In one possible implementation, in step 201, the selecting a plurality of candidate locations in a peripheral area of the measurement target includes: dividing the peripheral area of the measurement target into a plurality of subareas 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-areas obtained by dividing the peripheral area of the measurement target may be set according to actual needs, which is not limited in the 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 illustrates a schematic diagram of candidate labeling areas according to an embodiment of the disclosure; as shown in fig. 5, four areas of up, down, left and right are selected based on the coordinates of the center point of the measurement target (i.e. the switch 301 in the drawing) in the single line drawing, the preset interval is set to be 10 pixels, and then each area is traversed by taking 10 pixels as increment in the four areas of up, down, left and right, and each coordinate point (X, Y) obtained is used as a candidate labeling position of the measurement primitive group;
in one possible implementation, in step 202, the occlusion area of the measurement primitive group to other non-measurement primitives on the single line diagram at each candidate position is obtained;
for example, in the above step, by traversing the upper, lower, left and right four areas with 10 pixels as increments, 20 candidate positions (5 candidate positions in each direction area) are obtained, the measurement primitive group to be marked is assumed to be marked at each coordinate point of the 20 candidate positions in sequence, and further 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, and the number of pixel points occupied by the overlapping area may be taken as the occlusion area.
In one possible implementation manner, in step 203, the corresponding weighted value is obtained by performing a weighting process on the occlusion area;
for example, table 1 shows the weights of the occluded primitives, and as shown in table 1, the occlusion area weights of each candidate position relative to other primitives can be obtained according to the preset correspondence between primitive types and occlusion area weights, so as to obtain the weighted values S of the occlusion areas of the measured primitive groups on the single line diagram for all other primitives in each candidate position, that is, the occlusion area weighted values S1, S2, S3 and … corresponding to different candidate positions can be obtained. It should be noted that, specific values of the occlusion area weights corresponding to different primitive types may be determined according to factors such as importance of actual primitives, which is not limited in this embodiment.
Table 1 weights of occluded primitives
In a possible implementation manner, in step 204, the obtaining the labeling position by selecting a minimum value in the weighted values includes: obtaining a corresponding distance value by obtaining the distance between each candidate position of the measurement primitive group and the measurement target; and under the condition that the candidate position corresponding to the minimum value is not unique, determining the labeling position according to the distance value.
For example, searching for the minimum value in the weighted sum S sequence of the shielding areas (i.e. the weighted values S1, S2, S3 and … corresponding to each candidate position), and taking the candidate position corresponding to the minimum weighted value as the labeling position; and labeling the measurement primitive group in the single line diagram according to the labeling position.
In view of the fact that there are candidate positions corresponding to the weighted values that are not unique (i.e., the weighted values corresponding to the at least two candidate positions are the same), in the embodiment of the present disclosure, the distance L between the coordinate point (X, Y) and the measurement target is further calculated, and the at least two candidate positions with the weighted values that are equal to each other are further filtered, so that the coordinate point (X, Y) corresponding to the minimum value of the distance L is taken as the final labeling position.
For example, table 2 shows a record of different candidate position coordinates (X, Y) with occlusion area weighting values S, distances L; as shown in table 2, the minimum value in the sequence of the weighted sum S of occlusion areas is found to be 0, that is, the marked measurement does not occlude other primitives on the graph, the corresponding coordinate points are (640, 350) and (640, 360), that is, the minimum value appears multiple times, and the value of the distance L is further compared, because the coordinate point (640, 350) is closer to the switch (640, 300) 301, the coordinate point (640, 350) is selected as the marking position of the final multi-source measurement, and the measured primitive group is marked in the single line graph according to the marking position.
