[0027] Embodiment one

[0028] Figure 1 A flowchart of a power grid power flow diagram construction method is provided for the first embodiment of the present application. The present embodiment can be applied to the construction of a power grid power flow diagram, and is particularly suitable for the construction of a power grid power flow diagram based on power grid sensing data and layer logical relationships. The method can be performed by a power grid power flow diagram construction device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. As shown in the figure, the method comprises: Figure 1

[0029] S110, according to the layer logical relationship between the candidate template layer and the target element data in the basic layer, calling the target element data from the basic element data of the basic layer, and constructing the candidate template layer by using the target element data.

[0030] The layer logical relationship includes the association relationship between the candidate template layer, the target element data in the basic layer, and the target parameters required for the calibration of the target element data. Layers are like films containing text or graphics elements, which are stacked in order to form the final effect of the page. Layers can accurately position elements on the page. Text, images, tables, plug-ins can be added to the layer, and sub-layers can also be nested in the layer. The basic element refers to the power element in the power grid, which can include bus element, main transformer element, line element, substation element and power plant element. The basic element data refers to the image data corresponding to the basic element required for displaying the basic element in the power grid power flow diagram. The candidate template layer refers to a commonly used layer for constructing a power grid power flow diagram. The steady-state distribution of voltage and power in a power system is called power flow, and the circuit diagram formed by the voltage and power distribution of the power grid through electrical symbols such as lines, nodes and reactance elements is the power grid power flow diagram. The target element data refers to the basic element data that needs to be added to the candidate template layer, i.e., the basic element data required for constructing the candidate template layer. ​

[0031] Specifically, the logical relationship between the base layer and the candidate template layer can be constructed according to actual needs. For example, the association between the candidate template layer, the target element data in the base layer, and the target parameters required for the calibration of the target element data can be constructed in advance. According to the logical relationship between the base layer and the candidate template layer, the logical relationship between each sub-layer in the base layer and the candidate template layer is determined.

[0032] The target element data required for constructing each sub-layer in the candidate template layer is determined from the base element data in the base layer, and the target element data is called from the base layer. The target element data is used to construct each sub-layer in the candidate template layer. The constructed sub-layers are integrated to determine the candidate template layer.

[0033] For example, the method for constructing the template layer can be: according to the logical relationship, determining the target element data for constructing each sub-layer in the candidate template layer and the target parameters corresponding to the target element data from the base element data in the base layer; according to the target element data and the target parameters, constructing the candidate template layer.

[0034] The target parameters refer to the operating parameters of the power element corresponding to the target element data when the power element is operating in the power grid.

[0035] Specifically, according to the logical relationship, the target element data for constructing each sub-layer in the candidate template layer is determined from the base element data in the base layer. Different target element data corresponds to different target parameters. The target element data is added to each sub-layer in the candidate template layer corresponding to the target element data, and the sub-layers are integrated to construct the candidate template layer.

[0036] It can be understood that, according to the logical relationship, the target element data is called from the base element data in the base layer, and the target parameters are marked for the target element data, so as to construct the candidate template layer according to the target element data and the target parameters. This can realize the automatic construction of the candidate template layer and improve the construction efficiency of the candidate template layer.

[0037] S120, according to the power grid sensing data and the logical relationship, parameter calibration is performed on the target element data.

[0038] The power grid sensing data refers to the parameter values of the power element detected by the detection equipment of the power element in the operating process. For example, if the power element is a power transmission line element, the power grid sensing data can be the current value and the current limiting value of the power transmission line element.

[0039] Specifically, the layer logical relationship determines target element data of each sub-layer and target parameters corresponding to the target element data, and obtains power grid sensing data through a detection device of a power element in the power grid, determines specific values of the target parameters according to the power grid sensing data, and performs parameter calibration on the target element data in each sub-layer according to the specific values of the target parameters, so as to construct a candidate template layer according to the target element data after parameter calibration.

[0040] For example, the candidate template layer includes a line erection layer, an element current limiting value layer, a cross-section control value layer, and a special marker layer.

[0041] The line erection layer includes a cross-over spanning layer or a same-tower erection layer. The cross-over spanning layer refers to a sub-layer in the candidate template layer for displaying a cross-over spanning line. The power transmission line intersects with other lines such as a telecommunication line, a power line, a pipeline, a cableway, a railway, and a highway, to form a horizontal intersection angle, which is referred to as a cross-over spanning line. The same-tower erection layer refers to a sub-layer in the candidate template layer for displaying a same-tower erection line. The element current limiting value layer refers to a sub-layer in the candidate template layer for displaying a power element and a current limiting value of the power element. The cross-section control value layer refers to a sub-layer in the candidate template layer for displaying a power transmission cross-section and a related parameter value of a transmission power of the power transmission cross-section. The cross-section is a power transmission cross-section. In an actual power system, a system dispatcher often selects several lines between a contact power supply center and a load center as a power transmission cross-section according to geographical positions. The special marker layer refers to a sub-layer in the candidate template layer for displaying marker information of a special element. The marker information of the special element can include backup power automatic switching marker information, urban user substation marker information, special bus voltage loss event level marker information, and special 10kV bus substation marker information. The backup power automatic switching refers to a backup power automatic switching device, which is a protection device that can accurately determine a power supply state and implement delayed switching of the power supply after acquiring signals in an alternating current uninterrupted sampling manner and performing real-time Fourier calculation.

[0042] Further, the target element data can be calibrated by the following sub-steps:

[0043] S1201, determining target element data of each sub-layer in the candidate template layer according to the layer logical relationship.

[0044] S1202, calibrating target element data in the element current limiting value layer according to the power grid sensing data, to determine a power transmission line current limiting value, a main transformer high-voltage current limiting value, and a main transformer low-voltage current limiting value in the element current limiting value layer.

[0045] The target element data in the element current limiting value layer includes power transmission line element data and main transformer low bus element data in the power grid. The main transformer low bus refers to a main transformer low full-insulation tube type bus. When the current rises to a maximum value, it no longer rises but falls, and the maximum value of the detected current is the current limiting value. The main transformer high current limiting value refers to the main transformer high bus current limiting value; and the main transformer low current limiting value refers to the main transformer low bus current limiting value.

[0046] Specifically, the target element data in the element current limiting value layer includes power transmission line data and main transformer low bus data. In the element current limiting value layer, the target parameters of the power elements corresponding to the power transmission line data and the main transformer low bus data are current parameters. The power grid sensor data of the power elements corresponding to the power transmission line data is obtained according to the current detection device, and the power transmission line current limiting value corresponding to the power transmission line data is determined according to the power grid sensor data. The power transmission line current limiting value is marked in the element current limiting value layer close to the power transmission line data, and the conversion relationship between the power transmission line current limiting value and power can also be marked in the form of text below the power transmission line data in the element current limiting value layer.

[0047] The power grid sensor data of the power elements corresponding to the main transformer low bus data is obtained according to the current detection device, and the main transformer low bus current limiting value corresponding to the main transformer low bus data is determined according to the power grid sensor data. The main transformer low bus current limiting value is marked in the element current limiting value layer close to the main transformer low bus data, and the conversion relationship between the main transformer low bus current limiting value and power can also be marked in the form of text below the main transformer low bus data in the element current limiting value layer. The main transformer low bus current limiting value is the main transformer low current limiting value.

[0048] The power grid sensor data of the power elements corresponding to the main transformer high bus data is obtained according to the current detection device, and the main transformer high bus current limiting value corresponding to the main transformer high bus data is determined according to the power grid sensor data. The main transformer high bus current limiting value is marked in the element current limiting value layer close to the main transformer high bus data, and the conversion relationship between the main transformer high bus current limiting value and power can also be marked in the form of text below the main transformer high bus data in the element current limiting value layer. The main transformer high bus current limiting value is the main transformer high current limiting value.

[0049] S1203, according to the power grid sensor data, parameter calibration is performed on the target element data in the section control value layer to determine the power transmission line section value and the main transformer section value in the section control value layer.

[0050] The section value of the power transmission line is the interface value of the power transmission line, and the interface value refers to the transmission power of each line in the power transmission section. The section value of the main transformer includes the section limit of the low bus of the main transformer, the interface value of the low bus of the main transformer, and the overload coefficient of the low bus of the main transformer within a specified time. The section limit can be set according to actual needs, and the section limit is less than the sum of the transmission power limits of each line in the transmission section.

[0051] Specifically, the target element data in the section control value layer includes power transmission line data and main transformer low bus data. In the section control value layer, the target parameters of the power elements corresponding to the power transmission line data and the main transformer low bus data are the section parameters of the power transmission section. The power grid sensor data of the power elements corresponding to the power transmission line data is obtained according to the power detection equipment of the power transmission section, and the transmission power of the power transmission line in the power transmission section is determined according to the power grid sensor data. The transmission power of the power transmission line is taken as the section value of the power transmission line, and the power transmission line data in the section control value layer is parameterized according to the section value of the power transmission line. The section value of the power transmission line is marked near the power transmission line data in the section control value layer.

[0052] The power grid sensor data of the power elements corresponding to the main transformer low bus data is obtained according to the power detection equipment of the power transmission section, and the interface value of the main transformer low bus in the power transmission section and the overload coefficient of the main transformer low bus within a specified time are determined according to the power grid sensor data. The section limit of the main transformer low bus, the interface value of the main transformer low bus, and the overload coefficient of the main transformer low bus within a specified time are taken as the section value of the main transformer, and the main transformer low bus data in the section control value layer is parameterized according to the section value of the main transformer. For example, the section value of the main transformer can be marked in the form of a red curve and a number near the main transformer low bus data in the section control value layer.

[0053] S1204, according to the power grid sensor data, parameterizing the target element data in the special marking layer to determine the backup power automatic switching marking, the urban user substation marking, the important user substation marking, the special 10kV bus voltage loss event level marking, and the special 10kV bus substation marking in the special marking layer.

[0054] Among them, important users and important user substation markings can be specified according to actual needs.

[0055] Specifically, the target element data in the special marking layer includes backup power automatic switching data, urban user substation data, special bus data and special bus substation data. In the special marking layer, the target parameter of the backup power automatic switching device corresponding to the backup power automatic switching data is whether the backup power is automatically put into use; the target parameter of the power element corresponding to the urban user substation data is whether the power grid contains urban user substations and the number of urban user substations; the target parameter of the power element corresponding to the special bus data is the level corresponding to the 10kV bus voltage loss event, and the higher the level, the greater the harm caused by the special bus voltage loss event. For example, when the level corresponding to the 10kV bus voltage loss event is level one, the harm caused by the special bus voltage loss event is the smallest; when the level corresponding to the 10kV bus voltage loss event is level two, the harm caused by the special bus voltage loss event is the largest. The target parameter of the power element corresponding to the special bus substation data is the connection state of the special bus.

[0056] According to the grid sensing data, it is determined whether the backup power of the backup power automatic switching device corresponding to the backup power automatic switching data is automatically put into use, so as to determine the backup power automatic switching mark in the special marking layer, and the backup power automatic switching data in the special marking layer is parameterized according to the backup power automatic switching mark. For example, if there is a backup power automatic switching device in the power grid, but the backup power of the backup power automatic switching device is not automatically put into use, the backup power automatic switching mark in the special marking layer is B; if there is a backup power automatic switching device in the power grid, the backup power automatic switching device is a non-bus tie backup power automatic switching device, and the backup power of the backup power automatic switching device has been automatically put into use, and the time of putting into use is n seconds, then the backup power automatic switching mark in the special marking layer is BTn; n is a positive number; if there is a backup power automatic switching device in the power grid, the backup power automatic switching device is a bus tie backup power automatic switching device, and the backup power of the backup power automatic switching device has been automatically put into use, then the backup power automatic switching mark in the special marking layer is MBT.

[0057] According to the grid sensing data, it is determined whether the power grid contains urban user substations and the number of urban user substations, and the urban user substation data in the special marking layer is parameterized according to the determination result and the number of urban user substations. If the power grid contains urban user substations, and the number of urban user substations is greater than or equal to the number threshold, then the urban user substation mark in the special marking layer is C; if the power grid contains urban user substations, and the number of urban user substations is less than the number threshold, then the urban user substation mark in the special marking layer is LC; wherein the number threshold can be set according to actual needs, for example, it can be 50.

[0058] According to the power grid sensing data, the number of urban users lost due to 10kV busbar voltage loss and the load lost due to 10kV busbar voltage loss are determined, the level corresponding to the 10kV busbar voltage loss event is determined according to the number of urban users lost due to 10kV busbar voltage loss or the load lost due to 10kV busbar voltage loss, and the special busbar data in the special marking layer is parameterized according to the level corresponding to the 10kV busbar voltage loss event. If the 10kV busbar voltage loss event is a first-level event corresponding to the number of urban users lost due to 10kV busbar voltage loss, the special busbar voltage loss event level is marked as HC; if the 10kV busbar voltage loss event is a second-level event corresponding to the number of urban users lost due to 10kV busbar voltage loss, the special busbar voltage loss event level is marked as HHC; if the 10kV busbar voltage loss event is a first-level event corresponding to the load lost due to 10kV busbar voltage loss, the special busbar voltage loss event level is marked as HL; if the 10kV busbar voltage loss event is a second-level event corresponding to the load lost due to 10kV busbar voltage loss, the special busbar voltage loss event level is marked as HHL.

[0059] Alternatively, the load of urban users lost due to 10kV busbar voltage loss and the load lost due to 10kV busbar voltage loss can also be determined according to the number of urban users lost due to 10kV busbar voltage loss and the load lost due to 10kV busbar voltage loss, the level corresponding to the busbar voltage loss event is determined according to the load of urban users lost due to 10kV busbar voltage loss, and the special busbar data in the special marking layer is parameterized according to the level corresponding to the 10kV busbar voltage loss event. For example, if the 10kV busbar voltage loss event is a first-level event corresponding to the load of urban users lost due to 10kV busbar voltage loss, the special busbar voltage loss event level is marked as HCL; if the 10kV busbar voltage loss event is a second-level event corresponding to the load of urban users lost due to 10kV busbar voltage loss, the special busbar voltage loss event level is marked as HHCL.

[0060] According to the power grid sensing data, it is determined whether there is a special 10kV busbar substation in the power grid, if yes, a triangle is used as a special busbar substation mark to parameterize the special 10kV busbar substation in the special marking layer.

[0061] S1205, according to the power grid sensing data, the target element data in the line erection layer is parameterized to determine the cross-over line or the same-tower line in the line erection layer.

[0062] Among them, the line erection layer can be a cross-over layer or a same-tower erection layer.

[0063] Specifically, according to the power grid sensing data, it is determined whether there is a cross-over line or a same-tower line in the power grid, if yes, X is used as a mark of the cross-over line or the same-tower line in the line erection layer, and the target element data in the line erection layer is parameterized to determine the cross-over line in the cross-over layer or the same-tower line in the same-tower erection layer.

[0064] It can be understood that setting the line route laying layer, the element current limiting value layer, the cross section control value layer and the special mark layer in the candidate template layer, respectively configuring the target element data for each sub-layer in the candidate template layer, and then performing parameter calibration on the target element data in each sub-layer, can realize that each sub-layer in the candidate template layer respectively displays different target element data, so as to classify and display the device operation information in the power grid, facilitate the staff to check the device operation condition in the power grid flow diagram, and improve the checking efficiency of the device operation condition by the staff.

[0065] S130, constructing the power grid flow diagram according to the basic layer, the candidate template layer and the layer logical relationship.

[0066] Specifically, the corresponding relationship between the basic layer, the candidate template layer and the layer logical relationship is determined, and the above corresponding relationship is taken as the layer corresponding relationship, and the power grid flow diagram is constructed according to the basic layer, the candidate template layer, the layer corresponding relationship and the layer logical relationship.

[0067] Preferably, after the power grid flow diagram is constructed, when it is detected that the basic element data of the basic layer is updated, the candidate template layer in the power grid flow diagram is updated according to the update result of the basic element data and the layer logical relationship.

[0068] According to the update of the basic element data of the basic layer, the candidate template layer in the power grid flow diagram is updated, which can adjust the candidate template layer according to the change of the basic layer in real time, and ensure the accuracy of the candidate template layer in the power grid flow diagram.

[0069] The technical scheme provided by the embodiment is as follows: target element data is called from the basic element data of the basic layer according to the layer logical relationship between the basic layer and the candidate template layer, and the candidate template layer is constructed by using the target element data; the target element data is parameter calibrated according to the power grid sensing data and the layer logical relationship; and the power grid flow chart is constructed according to the basic layer, the candidate template layer, and the layer logical relationship. The above scheme introduces the concept of layer when constructing the power grid flow chart, calls the target element data required for constructing the candidate template layer from the basic element data of the basic layer, parameter calibrates the target element data, and determines the candidate template layer according to the parameter calibrated target element data; and constructs the power grid flow chart according to the basic layer, the candidate template layer, and the layer logical relationship. The scheme solves the problem that the search process of the staff for the abnormal equipment in the power grid is relatively complex and the search efficiency is relatively low. The scheme realizes the introduction of the concept of layer into the drawing of the power grid flow chart, classifies and displays the equipment operation information in the power grid flow chart, improves the search efficiency of the staff for the equipment operation, saves the processing time of the abnormal operation of the equipment, and facilitates the management of the equipment in the power grid.

[0070] For example, the method for determining the layer logical relationship between the basic layer and the candidate template layer can be as follows: determining the element-parameter association relationship between the target element data and the target parameters corresponding to the target element data, and the element-layer association relationship between the candidate target layer and the target element data; and determining the layer logical relationship according to the element-parameter association relationship and the element-layer association relationship. Specifically, the method can be implemented by the following steps:

[0071] Step 1: determining the element-layer association relationship between each sub-layer in the candidate template layer and the basic element data of the basic layer, and taking the basic element data associated with each sub-layer as the target element data of each sub-layer.

[0072] Specifically, the basic element data of the basic layer required for calling each sub-layer in the candidate template layer is determined according to the construction requirement of each sub-layer in the candidate template layer, so as to determine the element-layer association relationship between each sub-layer in the candidate template layer and the basic element data of the basic layer according to the calling condition of the basic element data and the construction condition of each sub-layer, and take the basic element data associated with each sub-layer as the target element data of each sub-layer.

[0073] Step 2: determining the element-parameter association relationship between the target element data and the target parameters required for calibrating the target element data.

[0074] Specifically, the target element data required by each sub-layer in the candidate template layer can be different, and the target parameters required for calibration of the target element data in each sub-layer are also different. Therefore, the target element data required by each sub-layer in the candidate template layer needs to be planned according to actual needs, and the target parameters required for calibration of the target element data in each sub-layer are determined. The target element data required by each sub-layer in the candidate template layer and the target parameters required for calibration of the target element data in each sub-layer are associated to determine the element and parameter association relationship between the target element data and the target parameters required for calibration of the target element data.

[0075] Step 3, the element and parameter association relationship and the element and layer association relationship are used as the layer logical relationship between the basic layer and the candidate template layer.

[0076] According to the element and parameter association relationship and the element and layer association relationship, the layer logical relationship between the basic layer and the candidate template layer is determined, which provides an optional scheme for constructing the layer logical relationship, and improves the efficiency of constructing the commonly used layer according to the layer logical relationship.

Specifically, as shown in Figure 2 The method comprises the following steps:

[0079] S210, according to the layer logical relationship between the basic layer and the candidate template layer, the target element data is called from the basic element data of the basic layer, and the target element data is used to construct the candidate template layer.
