[0019] It should be noted that the term “comprising” will be used in the embodiments of the present application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0020] In the existing rail transit industry, single-line comprehensive monitoring systems are widely used, and most of the line power monitoring systems operate independently. The core data such as real-time state and live state of equipment are stored in different systems, and there is a lack of unified data management platform, making it difficult to standardize integration and management. As a power supply hub of the line network, the main station is commonly used by multiple lines. When facing emergency scenarios such as main station failure and cross-line support power supply, it is difficult to quickly call the real-time load data of the associated lines, resulting in insufficient decision basis and limited response efficiency, which directly affects the timeliness and accuracy of emergency power supply scheduling.

[0021] With the rapid expansion of the urban rail transit line network, the demand for line network-level power monitoring is increasingly prominent, and there is an urgent need for a power monitoring scheme that can visualize multiple lines in the entire network. As a power supply core node, the dynamic visualization of the power supply range of the main station is crucial for monitoring special power supply scenarios, quickly locating faults, and scientifically optimizing load distribution for operation and maintenance personnel.

[0022] Based on this, the embodiment of the present application provides a rail transit main station power supply range visualization method, device and electronic equipment. The method accesses the SCADA system of all lines of the rail transit line network, and obtains real-time data in the SCADA system; based on the real-time data in the SCADA system and the whole network power topology modeling rule, a device live topology relationship is generated; wherein all devices in the same electrical island in the device live topology relationship have the same electrical island identifier; comparing the electrical island identifier of the device in the device live topology relationship, determining the real-time main station power supply range; the real-time main station power supply range includes the corresponding station equipment and section equipment of each main station in the rail transit line network; based on the real-time main station power supply range and the first main station color of each main station pre-configured, the station icon and the section line in the rail transit line network graph are rendered in real time, and the real-time power supply range of the main station is displayed; wherein the station icon and the section line of the same main station in the real-time power supply range are displayed with the first main station color, so that the standardized management of multi-line power data is realized through a unified data platform, and protocol differences and data islands are eliminated; through the dynamic visualization of the main station power supply range, combined with real-time topology calculation and line network graph scene rendering, operation and maintenance personnel can quickly lock the affected line section and associated main station after the main station failure occurs.

[0023] Please refer to Figure 1 , Figure 1 The method flowchart of the rail transit main station power supply range visualization method described in the embodiment of the present application is shown in Figure 1 The method comprises the following steps S101-S104: S101, access the SCADA system of all lines of the rail transit line network, and obtain real-time data in the SCADA system; S102, generating a device live topology relationship based on real-time data in the SCADA system and network-wide power topology modeling rules; wherein all devices in the same electrical island in the device live topology relationship have the same electrical island identifier; S103, comparing the electrical island identifier of the device in the device live topology relationship to determine the real-time main supply range; the real-time main supply range includes the corresponding station device and section device of each main in the rail transit line network; S104, based on the real-time main supply range and the pre-configured first main station color of each main station, real-time rendering of the station icon and section line in the rail transit line network diagram to display the real-time power supply range of the main station; wherein the station icon and section line of the same main station in the real-time power supply range are displayed with the first main station color.

[0024] In the step SS101, access the SCADA system of all lines of the rail transit line network to obtain real-time data in the SCADA system.

[0025] Access the SCADA system of all lines of the rail transit line network, realize standardized management of multi-line power data through a unified data platform, and eliminate protocol differences and data islands.

[0026] The real-time data in the SCADA system refers to the data obtained from the power monitoring system, and the precision can reach millisecond level.

[0027] The types of real-time data in the SCADA system are diverse, including switch position, protection action signal, device working condition, voltage, current, power, etc.

[0028] In the step S102, based on the real-time data in the SCADA system and the network-wide power topology modeling rules, a device live topology relationship is generated; wherein all devices in the same electrical island in the device live topology relationship have the same electrical island identifier.

[0029] Network-wide power topology modeling is to construct the connection relationship of power grid devices based on graph theory. Specifically, the modeling is performed through the conductive path formed by power supply devices (main transformer / bus / feeder) and closed switches to generate a device live topology relationship.

[0030] The electrical island is a cluster of devices electrically connected through closed switches, and there is a conductive path between any two points in the island, and there is no electrical connection between different islands.

[0031] The electrical island identifier is a dynamically allocated unique code (IslandNo), and all devices in the same electrical island have the same IslandNo, and different electrical islands have different IslandNo.

[0032] The electrical island identifier can also be referred to as IslandNo.

[0033] The electrical island identifier of the equipment in the electrical island is determined based on the original Island No of the main external network incoming line to which it is connected.

[0034] In step S103, the electrical island identifiers of the devices in the electrical topology are compared to determine the real-time main power supply range; the real-time main power supply range includes the station equipment and section equipment corresponding to each main station in the rail transit network.

[0035] Specifically, the station equipment includes a busbar section I and a busbar section II; the section equipment includes outgoing lines section I and outgoing lines section II.

[0036] Please refer to Figure 2 The comparison of the electrical island identifiers of devices in the electrical topology relationship to determine the real-time main power supply range includes the following steps S201-S203: S201, Subscribe to the electrical island identifiers for each Section I bus, Section II bus, Section I outgoing line, and Section II outgoing line; S202. Compare the electrical island markings of bus section I, bus section II, outgoing lines of section I and section II, and incoming lines of each main substation to determine the comparison results. S203. Based on the comparison results, determine that all devices with the same electrical island identifier as the main substation's external network incoming line belong to the main substation, so as to determine the real-time power supply range of the main substation.

[0037] The IslandNo of the main substation's external network incoming line represents the power supply from the city power grid to which the main substation is connected. Power can only be continuously conducted to the equipment through the conductor if and only if the equipment and the main substation's incoming line are on the same electrical island. Therefore, by comparing whether the electrical island identifiers of the I-section bus, II-section bus, I-section outgoing line, and II-section outgoing line are the same as those of the main substation's external network incoming line, the real-time power supply path and the connectivity between the main substations can be detected, thereby determining which main substation the I-section bus and II-section bus of the station, as well as the I-section outgoing line and II-section outgoing line of the section, belong to.

[0038] Compare the electrical island markings of bus section I, bus section II, outgoing lines of section I and section II, and incoming lines of each main substation to see if they are the same. In other words, the main substations connected to bus section I and bus section II of the same station may be the same or different; the main substations connected to outgoing lines of section I and outgoing lines of section II of the same section may be the same or different.

[0039] Thus, the method described in this application rigorously determines the real-time connectivity of the power supply path through the mathematical equivalence of electrical islands (same IslandNo), thereby determining the power supply range of the main substation. In the specific judgment, for the redundant segmented power supply architecture of rail transit (separate I / II sections), only a few key topological nodes such as the I section bus, II section bus, I section outgoing line and II section outgoing line are compared, and a small number of key nodes (bus / incoming and outgoing lines) are detected, covering the power supply status tracking of the entire network, thereby improving the real-time performance of the visualization method for the power supply range of the main substation.

[0040] In step S104, based on the real-time power supply range of the main substation and the pre-configured first main substation color of each main substation, the station icons and section lines in the rail transit network map are rendered in real time to display the real-time power supply range of the main substation; wherein, the station icons and section lines of the same main substation within the real-time power supply range are all displayed with the first main substation color.

[0041] Please refer to Figure 3 Based on the real-time power supply range of the main substation and the pre-configured first main substation color for each main substation, the station icons and section lines in the rail transit network map are rendered in real time to display the real-time power supply range of the main substation, including the following steps S301-S302: S301. In the rail transit network diagram, station icons are bound to Section I busbar and Section II busbar, and section lines are bound to Section I outgoing lines and Section II outgoing lines; among them, the first area of ​​the station icon is bound to Section I busbar, and the second area of ​​the station icon is bound to Section II busbar; the section lines are double lines, one bound to Section I outgoing line and the other bound to Section II outgoing line. S302. Based on the first main substation color, uniformly render the same station icons for the I-section busbar and II-section busbar bound to the electrical island of the main substation's external network incoming line, as well as the section lines bound to the I-section outgoing line and II-section outgoing line, to display the real-time power supply range of the main substation.

[0042] In some embodiments, the station icons in the rail transit network diagram are associated with bus section I and bus section II, including: For transfer stations where multiple lines intersect, the number of groups in the first and second zones of the station icon is determined based on the number of lines intersecting at the transfer station. Bind the first and second areas of different groups in the station icon to the I section bus and II section bus of different lines.

[0043] For example, in the network diagram, the inner circle of the station icon is divided into 4 quadrants (considering transfer stations), and the I and II sections of the busbars of the two lines are bound together; the filled area of ​​the section lines is bound to the I / II section incoming / outgoing lines.

[0044] In some embodiments, in the visualization method for the power supply range of the main rail transit substation, please refer to... Figure 4 After rendering the station icons and section lines in the rail transit network map in real time, the method further includes the following steps S401-S402: S401. When the real-time data corresponding to the main substation determines that the main substation meets the preset abnormal power supply conditions, the design power supply range of the main substation is displayed in the rail transit network map; wherein, the station icon and section lines of the main substation in the design power supply range are all displayed with the second main substation color; the preset scenarios include support power supply scenarios and temporary power outage scenarios; S402. Based on the real-time power supply range and the designed power supply range of the main substation simultaneously displayed in the rail transit network diagram, determine the comparison result between the real-time power supply range and the designed power supply range of the main substation.

[0045] When the real-time data corresponding to the main station determines that the main station meets the preset abnormal power supply conditions, it indicates that the power supply scenario of the rail transit network map is an abnormal power supply scenario (also known as an abnormal power supply scenario).

[0046] For example, the abnormal power supply scenarios include support power supply scenarios and temporary power outage scenarios.

[0047] Based on the real-time data corresponding to the main substation, it is determined whether the main substation meets the preset abnormal power supply conditions. For example, the judgment is made based on preset abnormal power supply conditions such as abnormal tripping of incoming circuit breaker, mismatch between feeder switch position and dispatch order, abnormal disconnection of bus tie switch, continuous over-limit of main transformer load rate, and bus voltage exceeding limit.

[0048] For example, the outer ring of the station icon and the outer frame of the section line in the network diagram are displayed in the color of the corresponding second main substation according to the designed power supply range.

[0049] In this way, for special scenarios such as emergency power supply after a main substation failure, the system can update the power supply path and coverage of other main substations in real time, and visualize the difference between the designed power supply range and the real-time power supply range, so that dispatchers can clearly understand the feasibility and implementation path of cross-line support.

[0050] In some embodiments, the designed power supply range of the main substation is shown in the rail transit network diagram, including: Obtain the pre-configured design power supply range for each master station; Based on the designed power supply range of each main substation and the pre-configured second main substation color of each main substation, the station icons and section lines in the rail transit network diagram are rendered to display the designed power supply range of the main substation; wherein, the station icons and section lines of the same main substation within the designed power supply range all display the second main substation color; the first main substation color and the second main substation color of the same main substation are different.

[0051] It should be noted that, in some embodiments, when it is determined based on the real-time data corresponding to the main substation that the main substation does not meet the preset abnormal power supply conditions, the designed power supply range of the main substation can also be displayed in the rail transit network diagram.

[0052] When the real-time data corresponding to the main substation determines that the main substation does not meet the preset abnormal power supply conditions, it indicates that the rail transit network is in a normal power supply scenario.

[0053] For example, when the colors of the first and second main substations are the same, it is a normal power supply scenario, and this is the display effect most of the time; when the colors of the first and second main substations are different, it is an abnormal power supply scenario, which can effectively provide an abnormality prompt.

[0054] In some embodiments, the method for visualizing the power supply range of a main rail transit substation further includes: The real-time rendered rail transit network map also displays main substation icons; the color of the main substation icons is the pre-configured first main substation color for each main substation. In response to the first operation on the main substation icon, a pop-up window displays text information about the designed power supply range of the main substation corresponding to the main substation icon.

[0055] In some embodiments, the method for visualizing the power supply range of a main rail transit substation further includes: Based on real-time data from the SCADA system, determine the real-time load rate of each master station; Based on a pre-set load rate threshold, the system determines in real time whether the load rate of each host is abnormal. If so, then control the corresponding main office icon to switch to the preset prompt state.

[0056] For example, the load rate threshold is 85%.

[0057] The real-time determination of whether the load rate of each master server is abnormal specifically involves determining whether the load rate of the master server exceeds the load rate threshold.

[0058] The main icon switches to a preset prompt state, which can be, for example, changing the color, flashing, etc.

[0059] In some embodiments, the background color of the main substation icon is a user-defined main substation color; the main substation icon can be used for interaction, specifically, clicking the icon will display a pop-up window showing the design power supply range text information; a flashing red warning will appear if the main substation load rate is ≥85% (user can modify).

[0060] Please refer to Figure 5 , Figure 5 This application illustrates a rail transit network diagram showing the real-time power supply range of the main station, as described in an embodiment of the present application.

[0061] Please refer to Figure 6 , Figure 6 This paper presents an overall flowchart of the visualization method for the power supply range of the main substation of rail transit as described in an embodiment of this application; as follows: Figure 6 As shown, the visualization method for the power supply range of the main rail transit station includes the following steps 1-9.

[0062] Step 1: Connect to the SCADA system of all lines in the network and obtain real-time data.

[0063] Step 2: Then, perform full-network power topology modeling - generate the energized topology relationships of devices (all devices on the same electrical island have the same IslandNo value).

[0064] Step 3: Users can customize the color of each main station, design the power supply range, load rate threshold, and other information through the interface.

[0065] Step 4: Network diagram: The inner circle of the station icon is divided into 4 quadrants (considering transfer stations), and the I and II busbars are bound to them; the filled area of ​​the section lines is bound to the I / II incoming / outgoing lines; the outer circle of the station icon and the outer frame of the section lines are displayed in the corresponding colors according to the design power supply range.

[0066] Step 5: Main Substation Icon: The background color is the user-defined main substation color; Interaction: Clicking the icon will display a pop-up window showing the design power supply range text information, and a flashing red warning if the main substation load rate is ≥85% (user can modify).

[0067] Step 6: Subscribe to the IslandNo values ​​of bus segments I and II and outgoing lines of segments I / II.

[0068] Step 7: Compare the IslandNo values ​​of bus sections I and II, outgoing lines of sections I / II, and incoming lines of each main substation with the IslandNo values ​​of the external network.

[0069] Step 8: Station icons with the same IslandNo value will have their inner ring and section line fill area displayed in the same color (user-defined main station color).
