[0053] In one exemplary embodiment, as Figure 2 shown, a power supply path analysis and display method is provided, which is applied to the terminal 102 in Figure 1 for example, including the following steps 202 to 206. Among them:

[0054] Step 202, obtaining the power supply demand for the power supply object, and determining at least one power supply path for supplying power to the power supply object according to the in-out line point of the power supply object in the preset power topology network.

[0055] The power supply object refers to a user or a point that needs to be prioritized to ensure power supply in a specific scenario, such as a hospital, a transportation hub, a data center, etc. The power supply demand refers to specific requirements for power supply to the power supply object, which can be a requirement for analyzing and visualizing the power supply path, and can also include power supply capacity, duration, reliability level, switching time, etc.

[0056] The preset power topology network is a digital model based on the actual structure of the power grid, including devices such as substations, transmission lines, switch devices, distribution transformers, and user nodes, as well as their connection relationships, and is usually stored in the form of graphics or databases (such as the power grid model in the GIS system).

[0057] The in-out line point refers to the power access point of the power supply object in the preset power topology network, including the in-line point and the out-line point. The power supply path refers to the complete power transmission path from the power source end, such as the substation bus, to the in-out line point of the power supply object, including transmission lines, switch devices, transformers, etc. In some embodiments, the power supply path includes a main supply path and a backup supply path. The main supply path refers to the path that mainly supplies power during normal operation, with all switches closed. The backup supply path refers to the standby path that is activated when the main supply path fails, containing disconnected tie switches or backup power sources.

[0058] In some embodiments, at least one power supply path for supplying power to the power supply object is determined according to the in-out line point of the power supply object in the preset power topology network, including: searching reversely to at least one substation bus for supplying power to the power supply object according to the in-out line point of the power supply object in the preset power topology network; retaining devices having a power supply relationship between each substation bus of the preset power topology network and the power supply object, and removing branch devices without a power supply relationship, to obtain at least one power supply path.

[0059] Step 204, at least one power supply path is analyzed respectively to determine at least one power supply path of the power supply object; each power supply path includes a transmission conductor and a feeder switch.

[0060] The transmission conductor refers to the conductor that transmits electrical energy between devices in the power supply path, which can be high-voltage transmission conductors, low-voltage transmission conductors, etc. according to voltage levels. Illustratively, the transmission conductor is used to connect devices such as substations, switch stations, and user nodes in the power supply path. The feeder switch refers to a switch device installed on the feeder line, which is used to control the passage of the line and has functions such as overcurrent protection, short circuit protection, and fault isolation.

[0061] The folding analysis refers to a method of layering and disassembling each transformer substation in a power supply path and determining the shortest power supply path. In some embodiments, each power supply path can be analyzed according to the voltage level to determine the corresponding power supply path, and the weak link in each power supply path can be identified to remove the weak link in the power supply path to obtain the power supply path. Each power supply path includes at least one power transmission conductor and at least one feeder switch.

[0062] In step 206, the first fixed value data of the power transmission conductor and the second fixed value data of the feeder switch are determined according to the parameter requirement in the power supply requirement, the fixed value information layer is drawn according to the layout requirement, the first fixed value data and the second fixed value data in the power supply requirement, the equipment layer is drawn according to at least one power supply path, and the fixed value information layer and the equipment layer are jointly displayed.

[0063] Among them, the power supply requirement has parameter requirement and layout requirement. The parameter requirement indicates the fixed value data (i.e. the first fixed value data) of the power transmission conductor and the fixed value data (i.e. the second fixed value data) of the feeder switch, and the layout requirement indicates the layout format of the first fixed value data in the fixed value information layer, such as 4x2 grid matrix layout, and indicates the layout format of the second fixed value data in the fixed value information layer, such as 4x1 single grid matrix layout.

[0064] The fixed value information layer is a layer for displaying fixed value data, which can display at least the first fixed value data and the second fixed value data. The equipment layer is a layer for displaying at least one power supply path, which is used to display the position, connection relationship and topology of each device in the power supply path. The fixed value information layer and the equipment layer are two independent layers, which can be displayed separately or simultaneously according to the requirement.

[0065] According to the parameter requirement and the layout requirement of the power supply requirement, the first fixed value data and the second fixed value data can be drawn in the fixed value information layer, and at least one power supply path can be drawn in the equipment layer. The fixed value information layer and the equipment layer can be jointly displayed, which is beneficial to intuitively present the correlation between the fixed value information, the power supply path and the power grid operation state, and beneficial to intuitively and comprehensively understand the power grid operation of the power supply object by the operation and maintenance personnel, and reduce the difficulty and risk of operation and maintenance decision.

[0066] In some embodiments, the first fixed value data and the second fixed value data are updated in real time, and the content displayed in the fixed value information layer and the equipment layer is updated synchronously, which is real-time linkage to dynamically display the latest power grid operation state, ensure the timeliness of information display, and improve the efficiency and reliability of power system operation and maintenance.

[0067] In the power supply path analysis and display method, the power supply demand for the power supply object is obtained, at least one power supply path for supplying power to the power supply object is determined according to the in-out line points of the power supply object in the preset power topology network, the at least one power supply path is analyzed respectively, at least one power supply path for the power supply object is determined, each power supply path includes a power transmission conductor and a feeder switch, the first fixed value data of the power transmission conductor and the second fixed value data of the feeder switch are determined according to the parameter demand in the power supply demand, the fixed value information layer is drawn according to the layout demand, the first fixed value data and the second fixed value data in the power supply demand, the equipment layer is drawn according to the at least one power supply path, and the fixed value information layer and the equipment layer are jointly displayed. The above scheme can determine at least one power supply path for the power supply object through the in-out line points and the folding analysis, and draw the equipment layer; the first fixed value data of the power transmission conductor and the second fixed value data of the feeder switch in the power supply path are determined according to the parameter demand and the layout demand in the power supply demand, and the fixed value information layer is drawn; the internal relationship between the power supply path and the fixed value information can be intuitively displayed through the joint display of the fixed value information layer and the equipment layer, which is beneficial to improving the operation efficiency and reliability of the power system.

[0068] In an exemplary embodiment, the layout demand in the power supply demand includes a first layout demand of power transmission fixed value data and a second layout demand of switch fixed value data; drawing the fixed value information layer according to the layout demand, the first fixed value data and the second fixed value data in the power supply demand includes: determining the position of the first fixed value data in the fixed value information layer according to the position of the power transmission conductor corresponding to the first fixed value data in the equipment layer and the first layout demand; determining the position of the second fixed value data in the fixed value information layer according to the position of the feeder switch corresponding to the second fixed value data in the equipment layer and the second layout demand; drawing the first fixed value data in the fixed value information layer according to the position of the first fixed value data in the fixed value information layer and the first layout demand, and drawing the second fixed value data in the fixed value information layer according to the position of the second fixed value data in the fixed value information layer and the second layout demand.

[0069] The power transmission fixed value data refers to the fixed value data related to the power transmission conductor, including but not limited to reclosing state, phase distance I / II / III segment fixed value, zero sequence current II / III / IV segment fixed value, etc. The switch fixed value data refers to the fixed value data related to the feeder switch, including but not limited to reclosing state, overcurrent I / II segment time, zero sequence I segment time, etc. The first layout demand is the layout format of the power transmission fixed value data indicated in the layout demand, which can be a 4x2 grid matrix layout, for example. The second layout demand is the layout format of the switch fixed value data indicated in the layout demand, which can be a 4x1 single grid matrix layout, for example.

[0070] The device layer displays a plurality of power transmission lines, and each power transmission line has corresponding first fixed value data. The terminal obtains the position of the power transmission line corresponding to the first fixed value data in the device layer, and determines the position of the first fixed value data in the fixed value information layer in combination with the first layout requirement. For example, the position of the first fixed value data in the fixed value information layer should satisfy the following constraint conditions, for example, the layout of the first fixed value data in the fixed value information layer satisfies the first layout requirement, the position of the first fixed value data in the fixed value information layer is close to the corresponding power transmission line, and there is no cross overlap with the position of the power transmission line.

[0071] The device layer displays a plurality of feeder switches, and each feeder switch has corresponding second fixed value data. The terminal obtains the position of the feeder switch corresponding to the second fixed value data in the device layer, and determines the position of the second fixed value data in the fixed value information layer in combination with the second layout requirement. For example, the position of the second fixed value data in the fixed value information layer should satisfy the following constraint conditions, for example, the layout of the second fixed value data in the fixed value information layer satisfies the second layout requirement, the position of the second fixed value data in the fixed value information layer is close to the corresponding feeder switch, and there is no cross overlap with the position of the feeder switch.

[0072] The terminal draws the first fixed value data in the fixed value information layer according to the position of the first fixed value data in the fixed value information layer and the first layout requirement, and draws the second fixed value data in the fixed value information layer according to the position of the second fixed value data in the fixed value information layer and the second layout requirement.

[0073] In the embodiment, the position of the first fixed value data in the fixed value information layer is determined by the first layout requirement and the position of the power transmission line corresponding to the first fixed value data in the device layer, and the position of the second fixed value data in the fixed value information layer is determined according to the second layout requirement and the position of the feeder switch corresponding to the second fixed value data in the device layer, which realizes accurate mapping between the fixed value information and the corresponding power transmission line or feeder switch, ensures that the fixed value information corresponds to the position of each device one by one, avoids misreading of information caused by position deviation, improves the accuracy of fixed value information display, and is beneficial to improving the operation and maintenance efficiency and reliability.

[0074] In one exemplary embodiment, the first fixed value data includes a fixed value item and a fixed value text; drawing the first fixed value data in the fixed value information layer according to the position of the first fixed value data in the fixed value information layer and the first layout requirement includes: determining the color corresponding to the fixed value item; in the case that the fixed value text is in a preset fixed value range, determining the color corresponding to the fixed value text as the color corresponding to the fixed value item; in the case that the fixed value text exceeds the preset fixed value range, determining the color corresponding to the fixed value text as a preset color; and drawing the first fixed value data in the fixed value information layer according to the color corresponding to the fixed value item and the color corresponding to the fixed value text.

[0075] The first constant value data includes a constant value item and a constant value text. The constant value item indicates a type of the constant value data, and the constant value text refers to specific data corresponding to the constant value item. For example, the constant value item is an overcurrent I section time, and the constant value text can be 0.3 seconds.

[0076] In some embodiments, a mapping relationship between the constant value item and the color is stored in the terminal. By querying the mapping relationship, the color corresponding to the constant value item can be determined.

[0077] The terminal can determine the color corresponding to the constant value text according to the color corresponding to the constant value item and the data size of the constant value text. For example, when the constant value text is within a preset constant value range, the constant value text follows the color of the constant value item. When the constant value text exceeds the preset constant value range, it indicates that the constant value item may have a fault or other abnormalities. The color corresponding to the constant value text is determined as a preset color, for example, red, thereby facilitating the intuitive display of the data abnormal power transmission conductor.

[0078] Similarly, the second constant value data includes a target constant value item and a target constant value text. The terminal draws the second constant value data in the constant value information layer according to the position of the second constant value data in the constant value information layer and the second layout requirement, including: determining the color corresponding to the target constant value item; when the target constant value text is within a target constant value range, determining the color corresponding to the target constant value text as the color corresponding to the target constant value item; when the target constant value text exceeds the target constant value range, determining the color corresponding to the target constant value text as a target color; and drawing the second constant value data in the constant value information layer according to the color corresponding to the target constant value item and the color corresponding to the target constant value text.

[0079] In some embodiments, the paths belonging to the main supply line and the paths belonging to the backup supply line in the supply guarantee path can be displayed differently. For example, the power transmission conductor and the feeder switch on the main supply line are drawn with thick lines, and the corresponding first constant value data is displayed with thick font; the power transmission conductor and the feeder switch on the backup supply line are drawn with lines of normal width, and the corresponding first constant value data is displayed with font of normal width.

[0080] In this embodiment, the constant value item is bound to the color through the preset mapping relationship, which facilitates the operation and maintenance personnel to quickly determine the equipment operating state only by the color. According to whether the constant value text is within the preset constant value range, the constant value text follows the color corresponding to the constant value item, or the constant value text is a preset color, which is beneficial to quickly locate the abnormal power transmission conductor, reduces human error, and improves operation and maintenance efficiency.

[0081] In an example embodiment, the at least one power supply path is respectively subjected to folding analysis, and at least one power supply path of the power supply object is determined, including: for each power supply path, starting from a first transformer substation supplying power to the power supply object, searching for a next transformer substation according to voltage levels step by step; in the case that the voltage level of the next transformer substation is not higher than that of the previous transformer substation, removing the next transformer substation; in the case that the voltage level of the next transformer substation is higher than that of the previous transformer substation, retaining the next transformer substation; starting from the next transformer substation, continuing to search according to the voltage levels until a transformer substation of a preset voltage level is searched; and determining the power supply path corresponding to the power supply path according to the first transformer substation and the retained transformer substations.

[0082] In which, each power supply path can determine one power supply path. The voltage level refers to the voltage level of each transformer substation in the power supply path, for example, 110kV, 110kV, 500kV, etc. The search direction is to start from the first transformer substation supplying power to the power supply object, and to search from low to high according to the voltage level step by step. The search termination condition is to search to the transformer substation of the preset voltage level, for example, to search to the transformer substation of 500KV, so as to determine the path top end of the power supply path as the power grid power supply node.

[0083] The screening condition of the search process is to remove the transformer substations of the same and low voltage level, that is, to remove the transformer substations without promoting the power supply level, and to retain the transformer substations of high voltage level. Starting from the first transformer substation, the retained transformer substations are combined to constitute the power supply path corresponding to the power supply path.

[0084] For example, the power supply path is “35kV transformer substation A→110kV transformer substation B→110kV transformer substation C→220kV transformer substation D→500kV transformer substation E”. After the folding analysis, the power supply path is “35kV transformer substation A→110kV transformer substation B→220kV transformer substation D→500kV transformer substation E”, that is, the same level redundant node C is removed, and the core power supply chain is clearly displayed.

[0085] In some embodiments, the first transformer substation (for example, 35kV / 110kV) and the last transformer substation (for example, 500kV) in the power supply path are unfolded internally, and the transformer substations (220kV / 110kV) in the middle can only display the in-out line switches.

[0086] In the embodiment, for each power supply path, the transformer substations that can be retained are screened according to the voltage level, so that the power supply path is ensured to be unidirectionally increased from low voltage level to high voltage level, the circulation or same level jump is avoided, and the hierarchical planning is realized; the power supply path after the folding analysis is used for display, the redundant nodes are removed, the key information can be avoided to be shielded by the dense nodes, and the operation and maintenance efficiency and reliability of the power system are improved.

[0087] In an example embodiment, the parameter requirement in the power supply requirement comprises a parameter requirement of the power transmission conductor and a parameter requirement of the feeder switch; determining the first setting data of the power transmission conductor and the second setting data of the feeder switch according to the parameter requirement in the power supply requirement comprises: obtaining power transmission setting data of the power transmission conductor and switch setting data of the feeder switch; determining the first setting data in the power transmission setting data according to the parameter requirement of the power transmission conductor; and determining the second setting data in the switch setting data according to the parameter requirement of the feeder switch.

[0088] In an example embodiment, the parameter requirement in the power supply requirement comprises a parameter requirement of the power transmission conductor and a parameter requirement of the feeder switch; determining the first setting data of the power transmission conductor and the second setting data of the feeder switch according to the parameter requirement in the power supply requirement comprises: obtaining power transmission setting data of the power transmission conductor and switch setting data of the feeder switch; determining the first setting data in the power transmission setting data according to the parameter requirement of the power transmission conductor; and determining the second setting data in the switch setting data according to the parameter requirement of the feeder switch.

[0089] The power transmission setting data and the switch setting data can be obtained from a data system of the power grid. The terminal determines the first setting data in the power transmission setting data that matches the parameter requirement of the power transmission conductor, and determines the second setting data in the switch setting data that matches the parameter requirement of the feeder switch.

[0090] In the embodiment, the first setting data is determined from the power transmission setting data and the second setting data is determined from the switch setting data according to the parameter requirement of the power transmission conductor and the parameter requirement of the feeder switch in the power supply requirement, so that the parameter requirement of the demand can be displayed in the setting information layer, and the power supply requirement can be accurately met.

[0091] In an example embodiment, the setting information layer and the device layer are jointly displayed, comprising: in response to selection of any item in the setting information layer and the device layer, displaying the selected layer.

[0092] In an example embodiment, the setting information layer and the device layer are jointly displayed, comprising: in response to selection of any item in the setting information layer and the device layer, displaying the selected layer.

[0093] In some embodiments, the setting information layer can also be hidden, and in the case that any power transmission conductor or feeder switch in the device layer receives a trigger instruction, the corresponding setting information in the setting information layer is displayed.

[0094] As Figure 3 Fig. 1 shows a schematic diagram of joint display of the setting information layer and the device layer in some embodiments. The substation 1 and the substation 2 are connected by a power transmission conductor, and the power transmission conductor has a feeder switch. The setting information layer and the device layer are displayed simultaneously, and the first setting information is displayed near the power transmission conductor and the second setting information is displayed near the feeder switch.

[0095] In this embodiment, the fixed value information layer and the device layer are independently displayed or synchronously displayed according to the selection of the user, which is beneficial to improve the operation and maintenance efficiency.

[0096] To illustrate the power supply path analysis and display method and effects in the scheme in detail, a most detailed embodiment is described below:

[0097] Step one, intelligent analysis of the power supply path: determine the power supply object, which can be multiple users, and obtain the in-out line points of the power supply object in the preset power topology network; determine at least one power supply path for the power supply object according to the in-out line points.

[0098] Step two, intelligent analysis of the power supply path:

[0099] 1. The main supply line is the switch that is fully closed in the power supply path, and the standby supply line is the switch that is disconnected.

[0100] 2. Starting from the first substation for supplying power to the power supply object, search the next substation according to the voltage level; in the case that the voltage level of the next substation is not higher than that of the previous substation, remove the next substation; in the case that the voltage level of the next substation is higher than that of the previous substation, keep the next substation; continue to search according to the voltage level from the next substation, until the substation of the preset voltage level is searched; determine the power supply path corresponding to the power supply path according to the first substation and the retained substations.

[0101] 3. The first substation (35kV / 110kV) and the last substation (500kV) on the power supply path are expanded internally, and the intermediate substations (220kV / 110kV) only need to display the in-out line switches.

[0102] Step three, intelligent layout of the power supply path graph:

[0103] Fold and analyze the at least one power supply path respectively to determine at least one power supply path of the power supply object; each power supply path includes a power transmission conductor and a feeder switch; determine the first fixed value data of the power transmission conductor and the second fixed value data of the feeder switch according to the parameter requirement in the power supply requirement, draw a fixed value information layer according to the layout requirement, the first fixed value data and the second fixed value data in the power supply requirement, draw a device layer according to the at least one power supply path, and jointly display the fixed value information layer and the device layer.

[0104] The first fixed value data of the power transmission conductor can include: reclosing state, phase distance I / II / III section fixed value, zero sequence current II / III / IV section fixed value; the layout requirement can be: 4*2 grid matrix layout. The second fixed value data of the feeder switch can include: reclosing state, overcurrent I / II section time, zero sequence I section time; the layout requirement can be: 4*1 single grid matrix layout.

[0105] The improved power supply guarantee map generation algorithm is adopted, and the device fixed value grid space occupation calculation module is integrated, so that the compact layout and non-crossing overlap of the device spacing position and the device fixed value grid position are realized.

[0106] The double-layer rendering architecture is realized based on OpenLayers. The device layer is rendered by SVG vector, and the scaling is not deformed. The fixed value information layer is rendered by a customized Canvas rendering plug-in, so that the fixed value text is switched with the fixed value item color, and the state color coding is switched with the fixed value range (for example, red represents the out-of-limit value).

[0107] The fixed value information layer and the device layer are jointly displayed.

[0108] The above-mentioned power supply path analysis and display method comprises the following steps: obtaining power supply demand for a power supply object; determining at least one power supply path for the power supply object according to the in-out line point of the power supply object in a preset power topology network; performing folding analysis on the at least one power supply path to determine at least one power supply path for the power supply object; each power supply path comprises a power transmission conductor and a feeder switch; determining first fixed value data of the power transmission conductor and second fixed value data of the feeder switch according to parameter demand in the power supply demand; drawing a fixed value information layer according to the layout demand, the first fixed value data and the second fixed value data in the power supply demand; drawing an equipment layer according to the at least one power supply path; and jointly displaying the fixed value information layer and the equipment layer. According to the above-mentioned scheme, the at least one power supply path for the power supply object can be determined through the in-out line point and the folding analysis, and the equipment layer can be drawn; the first fixed value data of the power transmission conductor and the second fixed value data of the feeder switch in the power supply path can be determined according to the parameter demand and the layout demand in the power supply demand, and the fixed value information layer can be drawn; the internal relationship between the power supply path and the fixed value information can be intuitively displayed through the joint display of the fixed value information layer and the equipment layer, which is beneficial to improving the operation efficiency and reliability of the power system. In addition, the power supply path analysis and the fixed value visualization are dynamically linked, and when the power grid operation state changes, the power supply path and the fixed value visualization information can be timely and synchronously updated, which is beneficial to the staff to make accurate decisions quickly; since the power supply path and the fixed value information can be effectively integrated, the staff can comprehensively understand the overall state of the power grid when facing a complex power grid operation scene. For example, when load transfer or fault handling is performed, the rationality of the equipment fixed value under different power supply paths can be intuitively judged, and the difficulty and risk of dispatching decisions are reduced. The visualization effect is good, the correlation between the fixed value and the power supply path, the power grid operation state can be intuitively presented, the staff can quickly extract key information from a large amount of data, provide comprehensive and intuitive decision support for the staff, and improve the efficiency and reliability of the power system operation.
