[0025] In order to make the purpose, technical scheme and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for the convenience of description, only the part related to the present application but not all the contents are shown in the accompanying drawings. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow chart describes each operation (or step) as a sequential process, many of the operations therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of each operation can be rearranged. The above process can be terminated when its operation is completed, but it can also have additional steps not included in the accompanying drawings. The above process can correspond to a method, a function, a procedure, a subroutine, a subprogram, etc.

[0026] Figure 1 A flow chart of a power system flow visualization method provided in an embodiment of the present application is given. The power system flow visualization method provided in an embodiment of the present application can be executed by a power system flow visualization device, which can be implemented by hardware and / or software and integrated in the power system flow visualization device.

[0027] The following description is made by taking the power system flow visualization device executing the power system flow visualization method as an example. Figure 1 , the power system flow visualization method includes:

[0028] S110: Obtain a power system flow drawing, determine multiple power system components in the power system flow drawing, location information of the power system components, and connection lines between the multiple power system components, and draw the power system flow drawing on a visualization canvas.

[0029] The power system flow chart provided by this solution is drawn on a visualization canvas. For example, in a visualization canvas created in a visualization drawing software, multiple power system components (each power system component corresponds to each power device in the power system, and the power system component can be a model or graph corresponding to the power device) can be drawn in the visualization canvas according to the distribution of each power device in the power system (such as generators, transformers, switches, transmission lines, loads, etc.), and connecting lines are connected between multiple power system components on the visualization canvas according to the connection relationship between each component in the power system. Optionally, the collection points corresponding to each power system component on the visualization canvas can be determined according to the collection points corresponding to the measuring equipment used to detect the power devices in the power system, and the relationship between the two can be bound.

[0030] In one embodiment, after configuring multiple power system components and connection lines between the power system components on the visualization canvas, a power system flow drawing can be generated based on the individual power system components on the visualization canvas, the location information of the power system components (the location on the visualization canvas, and / or the relative position between the power system components), and the connection lines between the multiple power system components.

[0031] For example, when it is necessary to visualize the power system flow, a power system flow drawing corresponding to the power system can be obtained, the power system flow drawing can be parsed and multiple power system components in the power system flow drawing, the location information of the power system components and the connecting lines between the multiple power system components can be determined.

[0032] Optionally, the user can draw power system components and connecting lines in a visual canvas created in a visual drawing software according to the distribution of each power device in the power system, and after generating a power system flow drawing, when there are changes in measuring equipment and power devices in the power system (for example, the addition, deletion, deactivation, etc. of power devices due to switch operation, fault isolation, equipment addition, line optimization, etc.) and / or changes in connection relationships (for example, the addition, deletion, deactivation, etc. of transmission lines between power devices), the user can update the collection points, power system components, location information, connecting lines, etc. on the visual canvas based on the original power system flow drawing according to the changes in measuring equipment, power devices and / or connecting wires, and save or save as the corresponding power system flow drawing, or recreate a new power system flow drawing based on the changed power system.

[0033] Optionally, multiple power system flow drawings may be saved, and a corresponding power system flow drawing may be selected according to the power system to be displayed to analyze and determine the corresponding power system components, location information, and connecting lines.

[0034] S120: Acquire point collection data of collection points bound to each power system component.

[0035] Exemplarily, after determining the corresponding multiple power system components, location information and connection lines in the power system flow diagram, the collection points bound to each electronic system component are determined, and the point collection data of these collection points are obtained.

[0036] In one embodiment, the metering devices (such as Internet of Things devices) corresponding to the various power devices in the power system serve as corresponding collection points, collect real-time collection data corresponding to the power devices in real time, and provide the real-time collection data as point collection data to the power system flow visualization device. Optionally, the metering device can send the point collection data to the power system flow visualization device in a wired and / or wireless manner, or send the point collection data to a preset server or database in real time, and the power system flow visualization device can obtain the point collection data from the preset server or database.

[0037] Optionally, the real-time collected data may be a combination of one or more of current data (e.g., three-phase current), voltage data (e.g., phase voltage, line voltage), apparent power, reactive power, active power, reactive electricity, powered electricity, and power factor.

[0038] S130: Determine the flow direction information and electrical strength information of each connecting line according to the point collection data.

[0039] Exemplarily, the flow direction and electrical strength information of each connecting line is determined based on the point-to-point data collected from each power system component.

[0040] The flow direction information can be used to indicate the flow direction of the power system flow between the power system components (for example, the flow direction of the current between the power system components), and can be used to reflect the flow direction of the power flow between the corresponding power devices. The flow direction information of the connecting line can be determined according to the change law of the point-level data collected in the power system flow. For example, in the power system, the flow generally flows from the node with high reactive power to the node with low reactive power, and the flow direction information of the connecting line between the various power system components can be determined accordingly.

[0041] The electrical strength information can be used to indicate the electrical strength of the power system flow on the connecting line, and can be used to reflect the electrical strength of the transmission line between corresponding power devices, where the electrical strength can be determined based on the current and / or voltage. For example, the electrical strength information can be determined based on the average value of data collected at points at both ends of the connecting line (such as current value and / or voltage value).

[0042] S140: Displaying power system components according to the location information, and displaying connection lines according to the flow direction information and the electrical strength information.

[0043] Exemplarily, each power system component is rendered and displayed according to the position information of each power system component, and each connection line is rendered and displayed according to the flow direction information and electrical strength information corresponding to each connection line. Among them, the flow direction of the connection line is consistent with the corresponding flow direction information, for example, the flow direction of the connection line can be indicated by a fixed or dynamic arrow display, for example, from an endpoint with high reactive power to an endpoint with low reactive power. Connection lines corresponding to different electrical strength information can be displayed in different display styles, for example, lines of different thicknesses and / or different colors correspond to connection lines with different electrical strength information. Flowing connection lines can also be used to indicate the flow direction of the flow, and different colored connection lines indicate the strength of the flow. For example, larger lines indicate greater power flow, and the color of the connection line can be determined according to the positive and negative values ​​of the power flow (such as green for outflow and red for inflow).

[0044] After rendering and displaying the power system components and connecting lines, the staff can observe the topological structure and flow direction of the power system in real time based on the displayed power system components and connecting lines, and can intuitively observe the flow of power in various parts of the power system. Optionally, the production and / or viewing of power system flow drawings can also be realized based on web technology. The power flow analysis system based on Web technology can be accessed on any device, including desktop computers, tablets and mobile phones. Users do not need to install additional software, which is convenient for configuration and viewing anytime and anywhere. The collected point data can be transmitted to the configuration diagram through the http network and displayed on the configuration diagram. And the power flow analysis solution that can be realized by dragging and dropping power system components and connecting lines based on web configuration (web configuration can provide editing mode (drawing use) and viewing mode (viewing use) for power system flow drawings) can achieve better user-friendliness, visualization, efficiency improvement, flexibility, and system reliability, etc., providing strong support for the analysis and management of power systems.

[0045] Users can easily build the power system topology through the visual canvas, reducing the complexity of the power system topology construction operation, so that non-professional users can also easily get started. When the user adjusts the components or connections, the system can instantly update the flow direction of the power flow, enhancing the user's interactive experience. And through the flow direction and color coding to intuitively display the flow direction and intensity of the power flow, users can quickly identify the operating status of the power system. Users can also view the power system at different perspectives and zoom levels, which is convenient for in-depth analysis of specific areas or components. And through the visual connection and parameter setting of the power system, the risk of calculation errors caused by manual input errors is reduced, and it supports the addition and configuration of multiple power components. Users can flexibly expand the system's intuitive decision support according to needs: through the clear flow direction display, it helps decision makers quickly identify potential problems and optimization solutions, and improves decision-making efficiency. By visually displaying the flow direction, users can identify potential problems in the power system earlier, such as overload or imbalance, so as to take corresponding measures, and by monitoring the flow direction, it helps operation managers optimize the operation of the power system and improve the safety and reliability of the overall system.

[0046] As described above, by obtaining the power system flow drawing, determining multiple power system components in the power system flow drawing, location information of the power system components, and connecting lines between the multiple power system components, obtaining the point collection data of the collection points bound to each power system component, and determining the flow direction information and electrical strength information of each connecting line based on the point collection data, the power system components can be displayed based on the location information, and the connecting lines can be displayed based on the flow direction information and the electrical strength information, wherein the power system flow drawing is drawn on a visual canvas, and the power system network can be flexibly constructed based on the real-time power system status, and the changes in the power system can be responded to in a timely manner, thereby improving the power system flow analysis effect.

[0047] Based on the above embodiments, Figure 2 A flowchart of another power system flow visualization method provided in an embodiment of the present application is given, and the power system flow visualization method is a specific embodiment of the power system flow visualization method described above. Figure 2 , the power system flow visualization method includes:

[0048] S210: Create a visualization canvas, display multiple power system components on the visualization canvas according to the component selection operation, and determine the location information of each power system component.

[0049] Exemplarily, a visualization canvas can be created in the visualization configuration software, and a visualization configuration software toolbar can be provided. The visualization configuration software toolbar provides power system components corresponding to various power devices. Users can select power system components in the visualization configuration software toolbar to trigger component selection operations.

[0050] In one embodiment, when a component selection operation triggered by a user is detected, multiple power system components can be displayed on a visualization canvas according to the component selection operation, and the position information of each power system component on the visualization canvas can be determined. The corresponding power system component can be added to the visualization canvas according to the component selection operation, and the user can drag the power system component on the visualization canvas, or the user can drag it to the visualization canvas according to the component selection operation.

[0051] In one possible embodiment, Figure 3 As shown in a schematic diagram of a power system component adding operation process, the power system flow visualization method provided by the present solution displays multiple power system components on a visualization canvas according to a component selection operation and determines the location information of each power system component, which may include:

[0052] S211: Determine a power system component in response to a selection operation on a candidate system component in a visualization component toolbar, and display the power system component on a visualization canvas.

[0053] S212: In response to a move operation on a power system component on the visualization canvas, move the position of the power system component on the visualization canvas.

[0054] S213: Determine the location information of each power system component according to the location of each power system component on the visualization canvas.

[0055] Exemplarily, when a user-triggered component selection operation is detected, the power system component can be determined in response to the selection operation of the candidate system component in the visualization component toolbar, and the power system component can be displayed on the visualization canvas. At this time, the user can move the power system component on the visualization canvas (for example, by dragging and dropping the power system component through a mouse, keyboard, touch panel, etc.) to move the position of each power system component on the visualization canvas.

[0056] In one embodiment, when a user-triggered movement operation is detected, the position of the power system component on the visualization canvas is moved in response to the movement operation on the power system component on the visualization canvas. For example, the user can trigger a movement operation on each power system component according to the relative position of each power device in the power system in reality, so that the relative position between the power system components on the visualization canvas corresponds to (is close to or consistent with) the relative position of each power device in the power system in reality. In one embodiment, the position information of each power system component can be determined according to the position of each power system component on the visualization canvas, and the position information can be recorded.

[0057] This solution displays power system components on a visualization canvas in response to selection operations, and moves the positions of power system components on the visualization canvas in response to move operations. The position information of each power system component can be determined according to the position of each power system component on the visualization canvas. Users can add and move power system components on the visualization canvas through selection operations and move operations to quickly create power system topology. The creation and editing of power system topology are simple, and non-professional users can also easily get started. When users adjust components or connections, the flow direction of the power flow can be updated instantly to enhance the user interaction experience.

[0058] S220: Determine the data collection point corresponding to each power system component, and bind each power system component to the corresponding data collection point.

[0059] For example, after the power system components are displayed on the visualization canvas, the metering equipment corresponding to each power device in the power system can be determined, and the corresponding points of the metering equipment can be used as the collection points corresponding to the power system components. The various power system components and the corresponding collection points can be bound, and the working status of the corresponding power system components can be determined based on the point collection data corresponding to the collection points.

[0060] S230: Display connection lines between multiple power system components according to the component connection operation performed on the visualization canvas.

[0061] S240: Generate a power system flow diagram according to the plurality of power system components, location information, and connection lines.

[0062] In one embodiment, a user may connect multiple power system components on a visualization canvas according to the connection relationship between various power devices in the power system to trigger a component connection operation. When a component connection operation performed on the visualization canvas is detected, connection lines between the multiple power system components may be displayed according to the component connection operation.

[0063] After completing the addition, position adjustment and connection line setting of power system components, a power system flow drawing can be generated based on multiple power system components, position information and connection lines on the visualization canvas.

[0064] This solution displays multiple power system components on a visual canvas according to component selection operations, and binds each power system component to the corresponding collection point. It can display the connection lines between multiple power system components according to the component connection operation to quickly and accurately generate power system flow drawings. The creation and editing of power system topology are simple, and non-professional users can also use it easily. The power system network can be flexibly built according to the real-time power system status, and the changes in the power system can be responded to in a timely manner to improve the power system flow analysis effect.

[0065] S250: Obtain a power system flow drawing, determine multiple power system components in the power system flow drawing, location information of the power system components, and connection lines between the multiple power system components, and draw the power system flow drawing on a visualization canvas.

[0066] S260: Acquire point collection data of the collection points bound to each power system component.

[0067] S270: Determine the flow direction information and electrical strength information of each connecting line according to the point collection data.

[0068] In a possible embodiment, the power system flow visualization method provided by the present solution determines the flow direction information of each connecting line according to the point collection data, including:

[0069] S271: Determine reactive power information in the data collected at each point.

[0070] S272: Determine flow direction information of the connection lines according to reactive power information corresponding to both ends of each connection line.

[0071] Exemplarily, after obtaining the point collection data (the point collection data includes reactive power information) of the collection points bound to each power system component, for each connecting line, the reactive power information in the point collection data of the power system components at both ends of the connecting line is determined, and the flow direction information of the connecting line is determined based on the corresponding reactive power information at both ends.

[0072] In one embodiment, the reactive power in the power system is generally transmitted in the direction of the flow, so the reactive power in each node of the power system gradually decreases along the direction of the flow, and the reactive power corresponding to the two ends of the connecting line decreases along the direction of the flow. Based on this, this solution determines the flow direction information of the connecting line according to the reactive power information corresponding to the two ends of each connecting line, which can be: when the reactive power information corresponding to the first end of the connecting line is greater than the reactive power information corresponding to the second end, the flow direction information of the connecting line is determined to flow from the second end to the first end; when the reactive power information corresponding to the first end of the connecting line is less than the reactive power information corresponding to the second end, the flow direction information of the connecting line is determined to flow from the first end to the second end.

[0073] Exemplarily, when the reactive power information corresponding to the first end of the connecting line is greater than the reactive power information corresponding to the second end, the flow direction information of the connecting line can be determined as flowing from the second end to the first end, and when the reactive power information corresponding to the first end of the connecting line is less than the reactive power information corresponding to the second end, the flow direction information of the connecting line can be determined as flowing from the first end to the second end.

[0074] This solution accurately determines the flow direction information of the connecting line through the reactive power corresponding to the power system components at both ends of the connecting line. It can flexibly display the power system flow according to the timing of the power system operation. Users can identify potential problems in the power system earlier, such as overload or imbalance, and take corresponding measures to improve the reliability of the power system. By monitoring the flow direction, it can effectively help operation and management personnel optimize the operation of the power system, improve the safety and reliability of the overall system, and optimize the operation and management of the power system.

[0075] S280: Displaying power system components according to the location information, and displaying connection lines according to the flow direction information and the electrical strength information.

[0076] Optionally, corresponding display parameters may be configured in advance for different electrical strength information, wherein the display parameters may be used to configure the display style (e.g., color and / or size) of the connecting lines. In one possible embodiment, the power system flow visualization method provided by the present solution displays connecting lines according to flow direction information and electrical strength information, including: determining the flow direction and display parameters of each connecting line according to the flow direction information and the electrical strength information; and displaying the connecting lines according to the flow direction and the display parameters.

[0077] Exemplarily, the flow direction of each connection line is determined according to the flow direction information, and the display parameters of each connection line are determined according to the electrical strength information. Each connection line can be rendered and displayed according to the flow direction and the display parameters.

[0078] In one embodiment, the power system flow visualization method provided by the present solution determines the flow direction and display parameters of each connecting line based on the flow direction information and the electrical strength information, which can be: determining the flow direction of each connecting line based on the flow direction information; determining the display color parameters and / or display size parameters of each connecting line based on the electrical strength information.

[0079] Exemplarily, the flow direction of each connection line is determined according to the flow direction information, for example, by adding a fixed or dynamic arrow on the connection line or on one side of the connection line, and indicating the flow direction of the connection line by the arrow.

[0080] In one embodiment, the display color parameters and / or display size parameters of each connecting line can be determined according to the electrical strength information, wherein the display color parameters are used to configure the display color of the connecting line, and the display size parameters are used to configure the display width of the connecting line. For example, the electrical strength information may include voltage levels and current values, different voltage levels may correspond to different display color parameters, different current values ​​may correspond to different display size parameters, and the larger the range corresponding to the current value, the larger the size corresponding to the display size parameter. This solution determines the flow direction and display parameters of each connecting line according to the flow direction information and the electrical strength information, and displays the connecting line according to the flow direction and display parameters. The display of the power system flow is more intuitive, allowing users to quickly understand the operating status of the power system.

[0081] In the above, by obtaining the power system flow drawing, determining the multiple power system components, the location information of the power system components and the connecting lines between the multiple power system components in the power system flow drawing, obtaining the point collection data of the collection points bound to each power system component, and determining the flow direction information and electrical strength information of each connecting line according to the point collection data, the power system components can be displayed according to the location information, and the connecting lines can be displayed according to the flow direction information and the electrical strength information, wherein the power system flow drawing is drawn on the visual canvas, and the power system network can be flexibly built according to the real-time power system state, and the changes of the power system can be responded to in time, and the power system flow analysis effect can be improved. At the same time, by displaying multiple power system components on the visual canvas according to the component selection operation, and binding each power system component with the corresponding collection point, the connecting lines between the multiple power system components can be displayed according to the component connection operation to quickly and accurately generate the power system flow drawing, the creation and editing operation of the power system topology is simple, and non-professional users can also easily get started, and the power system network can be flexibly built according to the real-time power system state, and the changes of the power system can be responded to in time, and the power system flow analysis effect can be improved.
