Description

Technical Field

[0001] This invention relates to the field of operation and maintenance of centralized monitoring systems for substations, and in particular to a rapid drawing method for matrix-type optical character displays in centralized monitoring systems for substations. Background Technology

[0002] Currently, the vast majority of substations with voltage levels of 220kV and below operate in an unmanned mode. Substation protection signals and other information are connected to the substation's centralized monitoring system via the dispatch data network. Monitoring personnel remotely monitor the substation by viewing the protection signals and other information on the centralized monitoring system. Indicator lights are one of the important tools for monitoring personnel to monitor substation protection signals. These indicator lights are maintained by the substation's centralized monitoring system maintenance personnel and used by the monitoring personnel.

[0003] Currently, there are two types of display formats for LED signs: one is a list format, which displays the protection signals of a single equipment bay through a single or multiple columns; the other is a matrix format, which displays the protection signals of multiple equipment bays simultaneously in a matrix format, generally belonging to several equipment bays of the same voltage level or the same equipment type.

[0004] List-style light bars are simple to create and can be directly retrieved from the database using SQL statements, making them easy to maintain. However, the number of protection signals displayed at the same time is very limited. When the monitor inspects the protection signals of the entire station, he / she needs to inspect each interval, which is inefficient. Matrix-style light bars can display signals of the same voltage level or similar equipment at the same time. When inspecting protection signals, the monitor can easily compare the protection signal status of each interval, which is more efficient.

[0005] Under current technological conditions, the production of matrix-type optical character panels is cumbersome, requiring each panel to be associated with protection signals. Each substation has approximately several hundred to several thousand protection signals. If the method of producing each panel individually is adopted, it is time-consuming, labor-intensive, and prone to errors and omissions. This is a shortcoming of the existing technology. Therefore, it is necessary to provide a rapid drawing method for matrix-type optical character panels in a substation centralized monitoring system to address the above-mentioned defects in the existing technology. Summary of the Invention

[0006] To address the problems existing in the prior art, this invention provides a rapid drawing method for matrix-type optical character displays in a substation centralized monitoring system. This method solves the problems of low efficiency, error-proneness, and omissions in creating protection signal optical character displays one by one, and significantly improves the work efficiency of system maintenance personnel in creating optical character displays.

[0007] The technical solution adopted in this invention is as follows:

[0008] A rapid drawing method for matrix-style optical character displays in a substation centralized monitoring system includes the following steps:

[0009] Obtain the protection signal table from the real-time database of the substation centralized monitoring system;

[0010] Divide all protection signals in the protection signal table into sub-tables according to voltage level;

[0011] Extract the device name, device number, and signal name of all protection signals from each sub-table;

[0012] Generate row headers and list headers for all protection signals in each sub-table and arrange them in a matrix form;

[0013] The protection signals in matrix form are saved in CIM / G file format and imported into the substation centralized monitoring system.

[0014] A computer-readable medium, wherein the computer program, when executed by a processor, implements a rapid drawing method for matrix-style optical character displays in a substation centralized monitoring system.

[0015] The beneficial effects of this invention are as follows: This invention further divides the protection signal table extracted from the real-time database of the substation centralized monitoring system into different categories of sub-tables, extracts the equipment name, equipment signal, and signal name from the different categories of sub-tables, generates row headers and list headers, and arranges them in a matrix form. This solves the problems of low efficiency and easy errors and omissions in making protection signal light signs one by one, and significantly improves the work efficiency of system operation and maintenance personnel in making light signs.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments: To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and with reference to the accompanying drawings. The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or arrangements discussed. It should be noted that the components illustrated in the drawings are not necessarily drawn to scale. The present invention omits descriptions of well-known components and processing techniques and processes to avoid unnecessarily limiting the present invention.

[0021] like Figure 1 As shown, in one embodiment of the present invention, the present invention provides a rapid drawing method for matrix-type optical character displays in a substation centralized monitoring system, comprising the following steps:

[0022] Step S1: Obtain the protection signal table from the real-time database of the substation centralized monitoring system;

[0023] Step S2: Divide all protection signals in the protection signal table into sub-tables according to voltage level;

[0024] Step S3: Extract the device name, device number, and signal name of all protection signals from each sub-table;

[0025] Step S4: Generate row headers and list headers for all protection signals in each sub-table and arrange them in a matrix form;

[0026] Step S5: Save the protection signals arranged in matrix form according to the CIM / G file format and import them into the substation centralized monitoring system.

[0027] In step S1, a protection signal table is acquired and stored on a per-substation basis. The protection signal table only needs to contain the name and ID of all protection signals, and the ID values ​​of all protection signals are added by 115964116992 to obtain the keyid of each protection signal.

[0028] The specific steps of step S2 are as follows:

[0029] S01. Obtain a protection signal according to the order of the signals stored in the protection signal table. If the name of the protection signal contains "second criterion" or "sensor abnormality", assign it to the second criterion sub-table and execute step S02. Otherwise, take the first 5 characters of the name of the protection signal and continue to judge. When assigning the protection signal to the sub-table, store the name and keyid of the same protection signal in the same row and adjacent column of the sub-table.

[0030] S02. If the first 5 characters contain "main transformer", then assign it to the main transformer interval sub-table and execute step S03. If the first 5 characters contain "220kV", then assign it to the 220kV interval sub-table and execute step S03. If the first 5 characters contain "110kV", then assign it to the 110kV interval sub-table and execute step S03. If the first 5 characters contain "35kV", then assign it to the 35kV interval sub-table and execute step S03. If the first 5 characters contain "10kV", then assign it to the 10kV interval sub-table and execute step S03. If the signal does not belong to any previous sub-table, then it is automatically assigned to the common interval sub-table.

[0031] S03. Determine whether all signals stored in the protection signal table have been allocated. If not, return to S01 to continue allocating the next signal; if all signals have been allocated, proceed to step S3.

[0032] The specific steps of step S3 are as follows:

[0033] S11. Process the 220kV sub-meter, 110kV sub-meter, 35kV sub-meter, and 10kV sub-meter. For any of the above sub-meters, obtain a protection signal according to the order of the signals stored in the sub-meter. Extract the characters between "kV" and the special meaning character in the name of the protection signal as the equipment name of the protection signal. Extract the consecutive numeric characters and English characters directly following the special meaning character of the protection signal as the equipment number. Extract all non-English characters after the equipment number as the signal name. The special meaning characters mentioned here include: "busbar", "bus tie", "section", "bridge", "line", etc.

[0034] S12. Process the second criterion sub-table and the main transformer bay sub-table. For a certain sub-table, according to the order of the signals stored in the sub-table, obtain a protection signal, extract the consecutive numeric characters directly connected to "kV" at the end of the protection signal name as the voltage level, extract the characters between "kV" and the special meaning character in the protection signal name as the equipment name of the protection signal, extract the consecutive numeric characters and English characters directly connected after the special meaning character of the protection signal as the equipment number, and extract all non-English characters after the equipment number as the signal name.

[0035] S13. Process the common interval sub-table and store the common interval sub-table signals in the order of the signals stored in the protection signal table;

[0036] S14. Determine whether all signals stored in each sub-table have been processed. If not, return to the sub-table step to continue processing the next signal. If all signals have been distributed, execute step S4.

[0037] In steps S11 and S12, the special meaning characters are prioritized as "bus", "bus tie", "section", "bridge" and "line". The first special meaning character appearing in the protection signal name is taken as the standard. If there is no directly connected numeric character after the special meaning character, the English characters are not extracted, the device number is defined as empty, and all characters after the special meaning character are directly extracted as the signal name.

[0038] The specific steps of step S4 are as follows:

[0039] S21. Traverse all signal device names in the sub-table and generate the list header of the light card matrix according to the order in which the signals are stored. If there is a duplicate device name, the device name will appear only once in the list header and will not be generated again in the list header of the light card matrix.

[0040] S22. Traverse the list header generated in step S21, select the set of signal device numbers in the sub-table whose device names are exactly the same as the list header, take the mode of the device number set as the device number of the list header, and append it to the list header text;

[0041] S23. Arrange and group the list headers according to the device name and device number in the list header;

[0042] S24. Generate row headers according to groups, traverse the device names in the group, match them with the device names of all protection signals in the sub-table, select the signal name of the matching protection signal to generate the row header of the group, and compare it with the existing row header in the group each time a row header is generated. If the row header already exists, discard it; otherwise, append it to the end of the row header.

[0043] S25. Determine whether the devices in the group have been traversed and whether the protection signals of the sub-tables of each device in the group have been traversed. If not, continue traversing. If yes, execute step S26.

[0044] S26. Traverse the protection signals in the sub-table. If the device name of a protection signal is exactly the same as the device name in the list header and the signal name of the protection signal is exactly the same as the signal name in the row header, then copy the keyid in the same row and adjacent column as the protection signal to the matrix with the row header as the row header and the list header as the column header, and delete the protection signal and keyid in the sub-table.

[0045] S27. Generate row headers, list headers, and matrices for each group according to the above steps. Check whether all protection signals and keyids in the sub-tables have been deleted. If not all have been deleted, return to step S21 to continue processing. If all have been deleted, proceed to step S5.

[0046] The step S23, which involves arranging and grouping the list header according to the device name and device number, includes: the device name has a higher priority than the device number; the device name is sorted according to the special meaning characters contained in it, with the priority of special meaning characters from high to low being "line", "bridge", "segment", "bus joint", and "bus line"; and the device numbers are arranged in the order of odd to even and small to large, with odd and even numbers taking precedence over size.

[0047] Step S5 specifically includes: generating CIM / G format labels for the row headers and list headers of each sub-table according to the format of the text box graphic; generating CIM / G format labels for the matrix elements storing keyid according to the format of the light sign graphic; and generating CIM / G format labels for the matrix elements that do not store any data according to the format of the text box graphic, but without filling in any content in the text box.

[0048] The present invention also provides a computer-readable medium having a computer program stored thereon, which, when executed by a processor, implements the rapid drawing method for the matrix-type optical character display of the substation centralized monitoring system.

[0090] If the first five characters contain "220kV", "110kV", or "35kV", then the corresponding signals will be assigned to the 220kV, 110kV, and 35kV sub-tables, respectively.

[0091] If a signal is not assigned to any previous sub-table, it is automatically assigned to the common interval sub-table.

If the device name of a protection signal is exactly the same as the device name in the list header and the signal name of the protection signal is exactly the same as the signal name in the row header, then copy the keyid of the protection signal in the same row and adjacent column to the matrix with the row header as the row header and the list header as the column header, and delete the protection signal and keyid from the sub-table.
