Description

Technical Field

[0001] The present application relates to the technical field of smart substations, and in particular to a method, device and medium for visualizing communication relations of smart substations. Background Art

[0002] With the development of the electric power industry, various intelligent devices are now commonly used to build smart grids to meet increasingly complex work needs. Among them, smart substations, as an important foundation and support for smart grids, play a vital role in the construction of smart grids. Smart substations usually contain dozens to hundreds of intelligent electronic devices (Intelligent Electronic Devices, IEDs) depending on the voltage level, and the homology relationship between each IED device is intricate. The substation configuration description file (Substation Configuration Description, SCD) describes the instance configuration, communication parameters, communication relationship between IED devices, and substation primary system structure of all IED devices in the smart substation. Therefore, when displaying information such as communication relationships in smart substations, it is usually visualized based on SCD files, and considering that the amount of configuration data information in SCD files is very large, traditional manufacturers mostly visualize SCD files based on the granularity of a single IED device.

[0003] The current method of visualizing the communication relationship of SCD files with a single IED device as the granularity allows staff to only understand the communication relationship between the current IED device and its surrounding IED devices, and cannot view the communication relationship between IED devices from the perspective of the entire station. The displayed information is not comprehensive enough and the display effect does not meet the needs.

[0004] Therefore, technical personnel in this field now urgently need a method for visualizing the communication relationship of smart substations to solve the current problem that when visualizing the communication relationship of smart substations, the displayed information is not comprehensive and the display effect does not meet the needs.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] The core of this application is to provide a method, device and medium for visualizing communication relations of a smart substation.

[0050] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] As an important part of smart grid, smart substation plays a supporting and cornerstone role in the construction of power grid. Smart substation includes dozens to hundreds of IED devices. The communication relationship between IED devices is complicated and depends on SCD files for description and storage. SCD files use pure Extensible Markup Language (XML) text format. Depending on the voltage level of the substation, the SCD file will contain tens to millions of lines of configuration data information. Such a huge amount of data brings serious understanding difficulties to power workers, and it is impossible to display all of it in a visual way. Therefore, at present, manufacturers usually visualize the communication relationship within the smart substation based on a single IED device as the display granularity, showing the communication relationship between a certain IED device and its surrounding connected IED devices, as well as the communication relationship between its internal optical ports.

[0052] Regarding the above-mentioned situation where a single IED device is used as the granularity for visualization, the power workers cannot understand the communication relationship between the IED devices inside the smart substation from the perspective of the entire station. They can only start from the local and piece together the communication relationship of the IED devices in the entire smart substation bit by bit, which also brings severe challenges to the power workers in understanding and mastering the internal communication relationship of the smart substation.

[0053] Based on the above reasons, this application provides a method for visualizing communication relationships of smart substations, such as Figure 1 As shown, including:

[0054] S11: Obtain the substation configuration description file.

[0055] From the above, it can be seen that the substation configuration description file, also known as the SCD file, describes the instance configuration, communication parameters, communication relationship between IED devices and substation primary system structure of all IED devices in the smart substation, including but not limited to: a list of all IED devices in the entire station, all optical ports contained in each IED, and the communication relationship between them.

[0056] S12: traverse and parse each IED tag in the substation configuration description file to obtain communication relationship data corresponding to each IED tag.

[0057] The communication relationship data represents the communication relationship between the current IED device and other IED devices.

[0058] Specifically, to further illustrate how step S12 is implemented, step S12 is described below with reference to an example:

[0059] S121: traverse and parse all IED tags whose Extensible Markup Language Path Language (XML Path Language, XPath) is “ / SCL / IED” in the SCD file.

[0060] S122: For a certain IED tag, assuming that the corresponding IED device is device A, traverse all ExtRef tags under it whose Xpath is " / SCL / IED / AccessPoint / Server / LDevice / LN0 / Inputs / ExtRef", obtain the "iedName" attribute of the ExtRef tag, and thus obtain the deduplicated set of "iedName" attributes of all ExtRef tags under device A.

[0061] Assume that the deduplicated set of all ExtRef tag "iedName" attributes under the above device A is {B, C, D}, that is, there is a communication relationship between device A and IED devices B, C, and D. Specifically, the communication relationship is: device A, as a signal receiver, receives signals sent by devices B, C, and D.

[0062] S123: Repeat step S122 for all IED tags until the communication relationships of all IED tags are obtained, thereby determining all communication relationship data of the smart substation.

[0063] By obtaining the communication relationship data corresponding to all IED devices, the communication relationship between all IED devices in the smart substation can be known, for example: IED device A subscribes to the data signals of IED devices B, C, and D; IED device B subscribes to the data signals of IED devices C and D; IED device D subscribes to the data signals of IED devices A and C, and so on.

[0064] S13: Establishing a communication relationship diagram of the entire station according to the acquired communication relationship data.

[0065] According to the communication relationship data obtained above, the communication relationship between all IED devices in the smart substation can be known, and then the corresponding visualization view, that is, the communication relationship diagram of the whole station, can be established.

[0066] The above generated full-station communication relationship diagram can be shown as Figure 4 As shown, it at least includes various IED devices and signal transmission relationships represented by arrowed line segments, wherein the arrow direction represents the transmission direction of the signal.

[0067] Furthermore, the whole station communication diagram may also have other information to facilitate the power staff to understand the communication relationship of the smart substation. This embodiment provides a preferred implementation scheme for this purpose. The above traversal and parsing of each IED tag in the substation configuration description file also includes:

[0068] Get the description information corresponding to each IED tag.

[0069] Obtaining the description information corresponding to the IED tag is to obtain the description information of the corresponding IED device. The specific acquisition steps can be as follows:

[0070] Obtaining the "desc" attribute value in the IED tag is to obtain the description information of the IED device.

[0071] For example, a possible description information is as follows: 110kVxxx line protection device.

[0072] Correspondingly, establishing a communication relationship diagram of the entire station according to the acquired communication relationship data also includes:

[0073] Displays the description information of each IED device.

[0074] This embodiment obtains the description information of the IED tag to facilitate the power workers to know the function of the IED device corresponding to the IED tag and distinguish it from other IED devices, which is more conducive to the power workers to understand the communication relationship within the smart substation.

[0075] In addition, it should be noted that the whole station communication relationship diagram provided by this application is based on all IED devices in the entire smart substation, and is based on the overall perspective to display the communication relationship between IED devices to the power staff in a visual way. In actual applications, the power staff also have the need to know the local detailed communication relationship, so this embodiment also provides a preferred implementation scheme, and the method also includes:

[0076] A device communication relationship diagram based on the granularity of a single IED device is generated according to the substation configuration description file.

[0077] Among them, the device communication relationship diagram is hidden as a subordinate view of the whole station communication relationship diagram, and is displayed after receiving the query request sent by the user end.

[0078] It should be noted that the query request sent by the user terminal mentioned above can be a selection instruction of a certain IED device in the whole station communication relationship diagram by the user, and the selection instruction can be in the form of single click or double click, etc., which is not limited in this embodiment. When a selection instruction for a certain IED device is received, the corresponding lower-level view device communication relationship diagram is displayed for viewing by power staff.

[0079] This application parses the SCD file to obtain the communication relationship between all IED devices in the smart substation, and then generates a full-station communication relationship diagram based on the communication relationship. The full-station communication relationship diagram generated by this method focuses on the communication relationship between IED devices, and displays it from an overall perspective, so that power workers can better understand the communication situation inside the smart substation, which reduces the difficulty of understanding compared to the current visualization method based on a single IED device as the granularity.

[0080] Based on the solutions provided in the above embodiments, power workers can grasp the communication relationship between the IED devices in the smart substation from an overall perspective based on the communication relationship diagram of the entire station. Considering that in the actual operation and maintenance of smart substations, most of the operation and maintenance is carried out in units of intervals (that is, all secondary devices related to a certain primary device, usually the devices in the same interval are set in the same cabinet). The traditional method cannot well reflect the division of intervals, and cannot enable power workers to clearly understand the communication relationship between intervals and within intervals.

[0081] Based on the above problems, in order to further reduce the difficulty of understanding for power workers and enable them to better understand the communication relationship within the smart substation, this embodiment also provides a preferred implementation scheme, which includes traversing and parsing each IED tag in the substation configuration description file:

[0082] Obtain the bay information corresponding to each IED tag.

[0083] The interval information includes the type of device, voltage level and device number.

[0084] In the current construction of smart substations, according to the standard specifications, iedName consists of 5 parts of visual characters, representing the device type, the device type, the voltage level, the device number, and the IED number, of which the voltage level and IED number fields are optional. That is, there are cases where the iedName of some IED devices does not include the voltage level and / or IED number fields.

[0085] For example, a possible iedName is IL2201B, where I represents the current device type as intelligent terminal; L represents the belonging device type as line; 22 represents the voltage level as 220kV; 01 represents the belonging device number as 1, that is, the belonging device is line 1; B represents the IED number as set B; so IL2201B indicates that the IED device corresponding to the iedName is set B of the 220kV line 1 intelligent terminal.

[0086] Another possible iedName is PT02A, where P represents the current device type as protection device; T represents the belonging device type as main transformer; 02 represents the belonging device number as 2; A represents the IED number as set A; PT02A represents set A of protection of main transformer No. 2, and there is no voltage level information at this time.

[0087] Accordingly, a communication relationship diagram of the entire station is established based on the acquired communication relationship data, such as Figure 2 As shown, including:

[0088] A station-wide communication relationship diagram is established according to the acquired communication relationship data, and IED devices located in the same interval in the station-wide communication relationship diagram are placed adjacent to each other according to the interval information.

[0089] In addition, it should be noted that, in order to determine the bay to which the IED device belongs, it is only necessary to obtain the belonging device type, voltage level and belonging device number in iedName as the bay information.

[0090] Also take the above two exemplary iedNames (IL2201B and PT02A) as an example for explanation, where the interval information of IL2201B is L2201, indicating that the interval to which it belongs is the 220kV No. 1 line interval; and the interval information of PT02A is T02, indicating that the interval to which it belongs is the No. 2 main transformer interval.

[0091] It is easy to understand that from the above description, it can be clearly known that according to the specification, iedName should consist of five parts: representative device type, belonging device type, voltage level, belonging device number, and IED number, but there are cases where the voltage level and / or IED number fields are not included. In this special case, the bay information also lacks corresponding information. For example, in the example PT02A, the bay information lacks the voltage level, but the bay to which it belongs can still be determined by the belonging device type and the belonging device number.

[0092] IED devices belonging to the same bay are placed adjacent to each other in the whole station communication relationship diagram, so that power workers can intuitively understand the communication relationship between bays and within bays, and better grasp the communication status of the smart substation.

[0093] It is easy to understand that the IED devices in the same bay can be marked or framed in the whole station communication relationship diagram to show their bay relationships, and different colors can also be used to indicate that the IED devices belong to different bays, and this embodiment does not limit this. Figure 2 As shown, the IED devices framed by the same dotted line belong to the same bay, and the IED devices framed by different dotted lines belong to different bays.

[0094] In addition, the interval name can also be displayed according to the interval information, so that the power staff can know the interval to which the IED device belongs. However, it should be noted that the location of the interval name display is not limited in this embodiment, and only a preferred implementation scheme is provided, in which the interval name is displayed in the corresponding dotted box, such as Figure 2 As shown, the interval name is displayed in the upper center part of the dashed box.

[0095] This embodiment obtains the interval information of each IED tag to determine the interval to which the corresponding IED device belongs, thereby placing the IED devices belonging to the same interval adjacent to each other, so that power workers can intuitively and conveniently view the communication relationship between IED devices in the same interval and the communication relationship between IED devices in different intervals. The communication relationship of IED devices inside the smart substation is displayed from the perspective of the interval, which is more conducive to the understanding of power workers.

[0096] Similar to the above embodiment, in the actual architecture of the smart substation, according to the different types of IED devices, it can be divided into process layer devices and interval layer devices. The IED devices at different layers are quite different, and the communication relationship between them is more concerned by power workers.

[0097] Therefore, in order to solve the above problem, this embodiment provides a preferred implementation scheme, traversing and parsing each IED tag in the substation configuration description file further includes:

[0098] The device type of the IED device corresponding to the IED tag is determined, and the hierarchical information of the corresponding IED device is determined according to the device type.

[0099] The layer information indicates whether the current IED device is a process layer device or a bay layer device.

[0100] The specific method for determining the corresponding IED device hierarchical information according to the device type includes:

[0101] When the device type is an intelligent terminal (indicated by the character I in iedName), a merging unit (indicated by the character M in iedName) or an integrated intelligent device (indicated by the characters MI / IM / U in iedName), the current IED device is a process layer device, otherwise it is an interval layer device.

[0102] For example, in the two examples in the above embodiments, the device type of IL2201B is I, indicating that it is an intelligent terminal and a process layer device; while the device type of PT02A is a protection device and a bay layer device.

[0103] Correspondingly, after obtaining the interval information of each IED tag, a communication relationship diagram of the entire station is established according to the obtained communication relationship data. Figure 3 As shown, including:

[0104] A station-wide communication relationship diagram is established based on the acquired communication relationship data, and IED devices with the same hierarchical information in the station-wide communication relationship diagram are placed adjacent to each other.

[0105] This embodiment obtains the hierarchical information of each IED device and sets the IED devices of the same layer adjacent to each other, so as to intuitively display the communication relationship of the IED devices between the process layer-process layer, process layer-interval layer, and interval layer-interval layer, which is more conducive to the power workers to understand the communication situation inside the smart substation.

[0106] like Figure 3 As shown, the process layer device and the bay layer device are respectively framed by solid line frames, and the layer name is marked in the solid line frame, that is, whether the layer is a process layer or a bay layer. It is easy to understand that the preferred solution provided by this embodiment for distinguishing whether the IED device is a process layer device or a bay layer device and displaying it does not conflict with the above-mentioned embodiment of distinguishing the bay to which the IED device belongs. Figure 4As shown, IED devices located in the same bay are arranged adjacent to each other, framed by the same dotted frame and marked with the bay name, and IED devices in the same layer are framed by the same solid frame and marked with layer information, so as to simultaneously display the communication relationship between IED devices in different bays, within the same bay, process layer-process layer, process layer-bay layer, and bay layer-bay layer, more comprehensively display the communication situation of the smart substation, and be more conducive to the operation and maintenance of the smart substation.

[0107] To further illustrate a method for visualizing communication relationships of a smart substation provided by the present application, the following describes in detail the visualization of all IED devices in a smart substation in combination with the above embodiments and actual application scenarios. Figure 5 As shown:

[0108] S21: Get the SCD file.

[0109] S22: Parse each IED tag in the SCD file to obtain corresponding communication relationship, description information, layer information and interval information.

[0110] Step S22 is further divided into four sub-steps S221, S222, S223 and S224, and there is no order between the sub-steps.

[0111] S221: For each IED tag, traverse all ExtRef tags under it, obtain the deduplicated set of "iedName" attributes of all ExtRef tags, and determine the communication relationship data of the IED tag accordingly to obtain the communication relationship data of all IED tags.

[0112] S222: For each IED tag, obtain its desc attribute value as description information, thereby obtaining the description information of all IED tags.

[0113] S223: For each IED tag, obtain its device type, and determine the hierarchical information of the IED device corresponding to the current IED tag based on the device type, so as to obtain the hierarchical information of all IED tags.

[0114] S224: For each IED tag, obtain its interval information, and determine the interval to which the IED device corresponding to the current IED tag belongs based on the information, so as to determine the interval to which all IED devices belong.

[0115] S23: Generate a communication relationship diagram for the entire station based on the communication relationship, description information, hierarchical information and interval information corresponding to each IED tag, wherein IED devices with the same hierarchical information are placed adjacent to each other and display the hierarchical name, and IED devices belonging to the same interval are placed adjacent to each other and display the interval name; and generate a subordinate visualization view based on the granularity of a single IED device based on the SCD file, which is displayed when a query instruction returned by the user end is received, otherwise hidden.

[0116] In the above embodiment, a method for visualizing communication relationship of a smart substation is described in detail, and the present application also provides an embodiment corresponding to a device for visualizing communication relationship of a smart substation. It should be noted that the present application describes the embodiments of the device part from two perspectives, one is based on the perspective of functional modules, and the other is based on the perspective of hardware.

[0117] Based on the perspective of functional modules, this embodiment provides a smart substation communication relationship visualization device, such as Figure 6 As shown:

[0118] An acquisition module 31 is used to acquire a substation configuration description file;

[0119] The parsing module 32 is used to traverse and parse each IED tag in the substation configuration description file to obtain communication relationship data corresponding to each IED tag; wherein the communication relationship data represents the communication relationship between the current IED device and other IED devices;

[0120] The view module 33 is used to establish a communication relationship diagram of the entire station according to the acquired communication relationship data.

[0121] Preferably, it also includes:

[0122] The subordinate view generation module is used to generate a device communication relationship diagram based on the granularity of a single IED device according to the substation configuration description file; wherein the device communication relationship diagram is hidden as a subordinate view of the whole station communication relationship diagram, and is displayed after receiving a query request sent by the user end.

[0123] Since the embodiments of the apparatus part correspond to the embodiments of the method part, please refer to the description of the embodiments of the method part for the embodiments of the apparatus part, which will not be repeated here.

[0124] The present embodiment provides a smart substation communication relationship visualization device, which obtains the SCD file through the acquisition module, and then parses the SCD file through the parsing module to obtain the communication relationship between all IED devices in the smart substation, so that the view module can generate a full-station communication relationship diagram based on the communication relationship. The full-station communication relationship diagram generated by the present embodiment displays the communication relationship between IED devices from an overall perspective, so that power workers can better understand the communication situation inside the smart substation from an overall perspective, which reduces the difficulty of understanding compared to the current visualization method based on a single IED device as the granularity.

The full-station communication relationship diagram generated by the present embodiment displays the communication relationship between the IED devices in the smart substation from an overall perspective, so that the power staff can better understand the communication situation inside the smart substation from an overall perspective. Compared with the current visualization method based on a single IED device as the granularity, it reduces the difficulty of understanding. At the same time, it will not cause the display to be complicated due to too much content to be displayed, which is not conducive to viewing by the power staff.

[0134] Finally, the present application also provides an embodiment corresponding to a computer-readable storage medium. The computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps recorded in the above method embodiment are implemented.

The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM), random access memory (RAM), disk or optical disk and other media that can store program code.

[0136] The computer-readable storage medium provided in this embodiment can obtain and parse the SCD file when the computer program stored therein is executed to obtain the communication relationship between all IED devices in the smart substation, and then generate a communication relationship diagram of the entire station based on the communication relationship. The visualization view established through the above steps shows the communication relationship between the IED devices of the smart substation from an overall perspective, so that the power staff can better understand the communication situation inside the smart substation. Compared with the current visualization method based on a single IED device as the granularity, it reduces the difficulty of understanding. At the same time, it will not cause the display to be complicated due to too much content to be displayed, which is not conducive to viewing by the power staff.
