Description

Technical Field

[0001] This invention relates to the field of power supply technology, and in particular to a method, system, intelligent device, and storage medium for real-time power supply path tracing. Background Technology

[0002] In power supply assurance for large venues (such as stadiums and conference centers), real-time monitoring of the venue's power supply path and the operational status of key equipment is a core prerequisite for responding to sudden power outages, quickly switching to backup lines, and ensuring uninterrupted power supply. Existing power supply path tracing technologies have many shortcomings in practical applications and cannot meet the high reliability and timeliness requirements of venue power supply assurance. Specific problems are as follows: 1. Delay in obtaining power supply path: Relying on manual querying of marketing system and power grid diagram data, it is impossible to dynamically synchronize the information of the power supply transformer (hereinafter referred to as "transformer") corresponding to the venue, resulting in inaccurate positioning of the starting point of path tracing, which becomes the source of subsequent tracing deviations; 2. Single switch status judgment: The on / off status of key switches such as tie switches and branch switches is judged only based on static diagram data without combining real-time power grid measurement data. This can easily lead to path misjudgment due to untimely updates of switch status, which affects the efficiency of fault handling. 3. Poor adaptability of primary and backup power supply modes: The traceability logic of the primary power supply line and the backup power supply line is not distinguished. The backup line needs to be manually simulated to query the switch status again, which is inefficient and prone to errors due to human error. It is impossible to quickly generate backup paths. 4. Rigid main grid path filtering: Transmission lines without real-time data are directly intercepted without flexibly adjusting the filtering strategy according to the actual situation of the power grid, such as voltage level and topology, resulting in incomplete path tracing; at the same time, only the core lines are displayed when the power supply path is displayed, which cannot present the overall architecture of the substation, making it difficult for operation and maintenance personnel to fully understand the operation of the power grid and affecting the scientific nature of power supply decision-making.

[0003] Therefore, there is an urgent need for a power supply guarantee method to overcome the shortcomings of existing technologies, improve the intelligence and automation level of power supply guarantee work in venues, and ensure the stable execution of power supply guarantee tasks. Summary of the Invention

[0004] The purpose of this invention is to provide a method, system, intelligent device, and storage medium for real-time power supply path tracing, which enables real-time, accurate, and complete tracing of power supply paths, fully automated execution of the process, reduced labor costs, and reliable decision support for power supply maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for real-time power supply path tracing includes: Constructing a digital model of the power grid based on GIS two-dimensional geographic graphics; Receive the power supply task instruction from the power supply target, extract the target identity identifier from the task instruction, and obtain the transformer identifier information that matches the power supply transformer of the power supply target based on the target identity identifier; Real-time measurement data is retrieved from the power grid measurement center, the transformer identification information is input into the power grid digital model, and the power supply path tracing process is carried out based on the real-time measurement data, starting from the transformer, to obtain the main power supply path of the distribution network, the backup power supply path of the distribution network, and the main power supply path of the main grid. The main power supply path, backup power supply path, and main power supply path of the distribution network are standardized, integrated, and displayed.

[0006] A further technical solution is that the real-time measurement data includes power flow data of transmission lines, tie switches, branch switches, substation outgoing line switches, substation bus tie switches, and real-time current, voltage, and power data of each switch.

[0007] A further technical solution is that the power supply path tracing process includes tracing the distribution network portion and tracing the main network portion; The distribution network traceability includes the main supply mode traceability logic for forming the main supply line of the distribution network and the backup supply mode traceability logic for forming the backup supply line of the distribution network. The main grid traceability includes the process of filtering out invalid main grid lines and the process of supplementing the main grid substation architecture.

[0008] A further technical solution is that the main power supply mode tracing logic is as follows: collect the real-time on / off status of all switches in the digital power grid model, follow the switch closed status to trace the topology upstream of the line, sequentially through closed branch switches and tie switches, until tracing to the substation outgoing switch, forming a complete distribution network main power supply path; The backup power supply mode traceability logic is as follows: collect the real-time on / off status of all switches in the digital power grid model, filter out all switches in the off state to form an off switch set, filter out the ring network switches connected to the power supply target from the off switch set, simulate the closing operation of the ring network switches in the digital power grid model, update the connectivity of the power grid structure, and trace back upwards from the transformer to form a complete distribution network backup power supply path.

[0009] A further technical solution is that the process of filtering out invalid main network lines is as follows: based on real-time measurement data, the real-time on / off status of the main network switch is determined, reverse power supply lines and data missing lines are filtered out, and lines without data are selected. If any data-free line meets any preset condition, the data-free line and the normally powered line are retained as valid main network lines. The specific process of supplementing the main grid substation architecture is as follows: extract all substations through which the effective main grid lines pass, supplement the auxiliary equipment in the substation that is not directly related to the core power supply path of the main grid, and integrate the core power supply path of the main grid with the auxiliary equipment of the substation to form a complete substation architecture.

[0010] A further technical solution is that the preset conditions include: Voltage level ≥ 110kV and single incoming line; It belongs to the linear variable group topology; At least one switch has real-time closure data.

[0011] A further technical solution is that the auxiliary equipment includes a busbar, a bus tie switch, and a main transformer.

[0012] Compared with the prior art, the real-time power supply path tracing method provided by the present invention has the following beneficial effects: 1. Dynamically locate the starting point to improve traceability accuracy: Dynamically obtain transformer information from the power marketing system through the venue's unique user number, and combine it with the precise geographic location capability of the power grid map to replace the traditional manual query method. This avoids the lag and error of manual operation, ensures the accuracy of the starting point of power supply path traceability, and improves traceability quality from the source. 2. Real-time measurement support and optimized switch status judgment: Based on high-frequency real-time measurement data every 5 minutes, combined with the connectivity analysis function of the power grid map, the on / off status of switches can be automatically and accurately judged, solving the problems of untimely status updates and path misjudgment caused by existing technologies that rely solely on static data, and improving the timeliness and accuracy of switch status judgment. 3. Adapt to main and backup power supply modes and improve power supply response efficiency: The different tracking logic of main and backup power supply modes is triggered by the trackingModel parameter. In the backup power supply mode, the ring network switch simulation closure and power grid reconstruction are automatically completed based on the power grid map without manual intervention. The efficiency of backup path generation is greatly improved, and it can quickly respond to the line switching needs under sudden faults. 4. Flexible filtering of main network paths to ensure complete traceability: For main network lines without real-time data, the filtering strategy is flexibly adjusted based on the actual situation of the power grid, such as voltage level, topology, and switch status, to avoid incomplete path tracing caused by blind interception; at the same time, by supplementing auxiliary equipment such as substation busbars and bus tie switches, the overall architecture of the substation is fully displayed, providing comprehensive data support for operation and maintenance personnel to fully understand the power grid situation and make scientific power supply decisions. 5. Full-process automation reduces labor costs: From dynamic positioning of the power supply starting point, acquisition of map and measurement data, to automated tracing of distribution network main and backup power supply paths and main network paths, and standardized output of results, the entire process relies on the digital model of the power grid and real-time data to achieve automated execution, reducing a large number of manual operations, significantly reducing the labor costs of power supply maintenance, while avoiding errors caused by manual operations and improving the intelligence level of power supply work.

[0013] The present invention also provides a real-time power supply path tracing system, comprising: The model building module is used to build digital models of power grids based on GIS two-dimensional geographic graphics. The transformer identification module is used to receive the power supply task instruction of the power supply target, extract the target identity identifier of the power supply target from the task instruction, and obtain the transformer identification information that matches the power supply transformer of the power supply target based on the target identity identifier; The path tracing module is used to retrieve real-time measurement data from the power grid measurement center, input the transformer identification information into the power grid digital model, and perform a power supply path tracing process based on the real-time measurement data, starting from the transformer, to obtain the main power supply path of the distribution network, the backup power supply path of the distribution network, and the main power supply path of the main grid. The integrated output module is used to standardize and integrate the main power supply path, backup power supply path, and main power supply path of the distribution network, and then output and display them.

[0014] The present invention also provides an intelligent device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements any of the aforementioned real-time power path tracing methods.

[0015] The present invention also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements any of the aforementioned real-time power supply path tracing methods.

[0016] Compared with the prior art, the beneficial effects of the system, device and medium provided by the present invention are the same as the beneficial effects of the methods described in the above technical solutions, and will not be repeated here. Attached Figure Description

[0017] The accompanying drawings, which are included to provide a further understanding of the invention and form part of this invention, illustrate exemplary embodiments of the invention and are used to explain the invention, but do not constitute an undue limitation of the invention. In the drawings: Figure 1 A flowchart of a method provided in an embodiment of the present invention. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0020] This invention provides a method for real-time tracing of power supply paths, such as... Figure 1 As shown, the main process of the method is described below.

[0021] Step S1: Construct a digital model of the power grid based on GIS two-dimensional geographic graphics.

[0022] Among them, the power grid digital model is based on a single map of the power grid constructed based on GIS geographic two-dimensional graphics. It is a power grid network map with full connectivity and has the function of judging node connectivity.

[0023] The construction logic of the power grid digital model is as follows: First, collect the precise location information of all equipment such as lines, switches, transformers, and substations in the power grid structure, complete the geographical modeling of the equipment in the geographic map, and then, based on the physical connection relationship between the equipment, associate the dispersed equipment across the entire domain to form a fully connected power grid structure map. The power grid digital model has the core function of automatically judging the grid connection status through node relationships, providing a topological basis for path tracing.

[0024] Step S2: Receive the power supply task instruction from the power supply target, extract the target identity identifier of the power supply target from the task instruction, and obtain the transformer identifier information that matches the power supply transformer of the power supply target based on the target identity identifier.

[0025] The identification of power supply targets (such as stadiums and conference centers) is a unique user number used to match the corresponding power supply transformer. The transformer identification information includes its name and GIS_ID, which is dynamically obtained after initiating a data request to the power marketing system. The GIS_ID is the transformer's unique identifier in the geographic information system and is the core basis for subsequent topology positioning in the power grid digital model.

[0026] Because transformer identification information may change due to factors such as the year of operation and changes in the electricity marketing system ledgers, dynamically retrieving data from the electricity marketing system replaces the traditional manual query method, ensuring the real-time and accurate location of the power supply starting point and avoiding the problem of tracing the starting point deviation from the source.

[0027] Step S3: Retrieve real-time measurement data from the power grid measurement center, input the transformer identification information into the power grid digital model, and perform a power supply path tracing process based on the real-time measurement data, starting from the transformer, to obtain the main power supply path, backup power supply path, and main power supply path of the distribution network.

[0028] The real-time measurement data is acquired by the dispatch automation system at a frequency of 5 minutes per acquisition. This includes power flow data for transmission lines (including current direction and magnitude), tie switches, branch switches, substation outgoing line switches, substation bus tie switches, and real-time current, voltage, and power data for each switch, used to automatically determine the on / off status of the switches. The format of the real-time measurement data is as follows: Power flow data adopts the floating-point format of the IEC 60870-5-101 / 104 protocol, including active power (unit kW, accuracy 0.1kW), reactive power (unit kVar, accuracy 0.1kVar), current (unit A, accuracy 0.01A), and voltage (unit kV, accuracy 0.01kV); switch status data adopts Boolean format (0 indicates open, 1 indicates closed), with a data transmission cycle of 5 minutes per acquisition. The data timestamp adopts UTC timestamp format (accurate to milliseconds), and the data packet is encapsulated in JSON format, with fields including device ID, measurement type, measurement value, data quality code, and acquisition timestamp.

[0029] This embodiment analyzes whether the current and voltage values ​​of the switch are within the normal operating range to achieve automated and accurate judgment of the switch's current on / off state, providing real-time status data for path tracing. This step integrates power grid geographic model data and real-time measurement data to construct a dual tracing foundation of "static topology + dynamic status," solving the problem of inaccurate status judgment caused by existing technologies relying solely on static data.

[0030] The power supply path tracing process includes distribution network tracing and main grid tracing. Distribution network tracing includes main supply mode tracing logic for forming the main supply lines of the distribution network and backup supply mode tracing logic for forming the backup supply lines of the distribution network. The main supply mode tracing logic and backup supply mode tracing logic are triggered by the trackingModel parameter, which includes the GIS_ID of the substation dynamically obtained from the power marketing system, the tracing direction (load → power source), and the equipment type. This parameter is the core identification identifier for the tracing mode. Main grid tracing includes the process of filtering out invalid main grid lines and the process of supplementing the main grid substation architecture.

[0031] More specifically, the format of the trackingModel parameter is as follows: (1) Transformer GIS_ID: The format is an 18-bit encoded string (such as "GD-JX-NC-001-10KV-TF-00001"). The first two digits are the province code, the middle digits are the city, district, voltage level, and equipment type code, and the last five digits are the serial number. It is obtained in real time through the power marketing system API interface and is used to locate the traceability starting point in the power grid digital model. (2) Traceability direction: The enumeration type takes the value "load_to_source" (load side → power supply side, i.e., main supply mode) or "source_to_load" (power supply side → load side). It is automatically set by the system according to the power supply task type. Under the power supply task, the default value is "load_to_source". (3) Equipment type: The enumeration type takes the value "transformer", "switch", and "line" to limit the range of equipment to be included in the traceability process. The judgment conditions for the main supply mode tracing logic and the backup supply mode tracing logic are as follows: When the transformer GIS_ID has a matching node in the power grid digital model, the trackingModel parameter is automatically filled, with "load_to_source" (load side → power source side) as the default tracing direction, triggering the main supply mode tracing logic to form the main power supply path of the distribution network; when the power supply guarantee task includes the requirement to generate a backup supply path (such as the main supply line having a maintenance plan or fault warning), the tracing direction is switched to "source_to_load" (power source side → load side), triggering the backup supply mode tracing logic to form the backup power supply path of the distribution network; if the transformer GIS_ID has no matching node in the model, an error message is returned and the tracing is terminated.

[0032] Specifically, the main power supply mode tracing logic is as follows: The real-time on / off status of all switches in the digital power grid model is collected, and the topology is traced upstream along the line following the switch's closed state, sequentially passing through closed branch switches and tie switches, until the substation outgoing switch is reached, forming a complete main power supply path for the distribution network. The backup power supply mode tracing logic is as follows: The real-time on / off status of all switches in the digital power grid model is collected, and all switches in the open state are selected to form an open switch set. From this set, ring network switches connected to the power supply target are selected, and the closing operation of these ring network switches is simulated in the digital power grid model to update the network connectivity. Starting from the substation, the tracing is restarted upstream to form a complete backup power supply path for the distribution network.

[0033] The process of filtering out invalid main network lines is as follows: Based on real-time measurement data, the real-time on / off status of the main network switch is determined, reverse power supply lines and lines with missing data are filtered out, and lines without data are selected. If any of the preset conditions are met, the lines without data and lines with normal power supply are retained as valid main network lines.

[0034] The criteria for determining a reverse power supply line are as follows: when the power flow direction of the transmission line is opposite to the standard power flow direction from the main grid to the distribution network, i.e., the active power value of the line is negative and the absolute value is greater than the preset threshold P_threshold, it is determined to be a reverse power supply line. The preset threshold P_threshold is 5% of the line's rated transmission capacity. When |P_real|>P_threshold and P_real<0, the line is marked as being in a reverse power supply state. Simultaneously, cross-verification is performed using the real-time current direction of the switches at both ends of the line. If the current direction at both ends points towards the distribution network side, the line is confirmed to be in a reverse power supply state and is filtered out. The preset conditions include: 1) voltage level ≥ 110kV and a single incoming line; 2) belonging to a line-transformer group topology; 3) at least one switch has real-time closing data.

[0035] The process of supplementing the main grid substation architecture is as follows: All substations traversed by valid main grid lines are extracted; auxiliary equipment within these substations that is not directly related to the core power supply path of the main grid is added; and the core power supply path of the main grid is integrated with the substation auxiliary equipment to form a complete substation architecture. Auxiliary equipment includes busbars, bus tie switches, and main transformers.

[0036] Step S4: Standardize and integrate the main power supply path, backup power supply path, and main power supply path of the distribution network, and output and display them.

[0037] Specifically, standardization and integration involves classifying and integrating the transmission and transformation equipment of the main grid and distribution network according to the main supply and backup supply types, displaying them in a unified manner, and enabling power dispatching and power supply maintenance personnel to view, analyze, and make decisions in real time, providing support for line monitoring, fault handling, and line switching in the power supply guarantee work.

[0038] This invention dynamically retrieves transformer information from the power marketing system using a unique user ID for each venue, dynamically locating the starting point and improving traceability accuracy. It also enhances power supply response efficiency by triggering differentiated traceability logic for primary and backup supply modes through the `trackingModel` parameter. For main grid lines without real-time data, it flexibly adjusts filtering strategies based on actual grid conditions such as voltage level, topology, and switch status to ensure traceability integrity, providing comprehensive data support for maintenance personnel to fully understand the grid situation and make informed power supply decisions.

The transformer identification module is used to receive the power supply task instruction of the power supply target, extract the target identity identifier of the power supply target from the task instruction, and obtain the transformer identification information that matches the power supply transformer of the power supply target based on the target identity identifier; The path tracing module is used to retrieve real-time measurement data from the power grid measurement center, input the transformer identification information into the power grid digital model, and perform a power supply path tracing process based on the real-time measurement data, starting from the transformer, to obtain the main power supply path of the distribution network, the backup power supply path of the distribution network, and the main power supply path of the main grid. The integrated output module is used to standardize and integrate the main power supply path, backup power supply path, and main power supply path of the distribution network, and then output and display them.
