The substation refers to a place in the power system where voltage and current are transformed, electric energy is received and distributed. The construction of the substation monitoring system is very important for the safety management and operation and maintenance efficiency of the substation.

[0003] However, the substation monitoring for regional centralized control involves the drawing of a large number of electrical pictures. A region usually includes multiple power substations, and the electrical monitoring main picture and various sub-pictures of a single substation are as high as dozens, each picture including numerous electrical equipment and lines. Traditional professional drawing software such as CAD has certain requirements for industrial drawing capability. If a large drawing or complex logic configuration is to be processed, it is easy to cause lag, and high-performance computers and sufficient manpower need to be provided.

[0004] Therefore, the traditional industrial drawing method cannot cope with the problems of numerous substation monitoring pictures and complex logic configuration, and not only requires a large amount of drawing manpower, but also is difficult to realize real-time state monitoring of devices such as transformers, high-voltage circuit breakers, disconnectors, grounding switches, and busbars.

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0041] It should be noted that the step numbers in the text are only for the convenience of explaining the specific embodiments, and do not serve as the basis for determining the execution sequence of the steps. The method provided in the present embodiment can be executed by a related server, and the server is taken as an example for description hereinafter.

[0042] As shown in Figures 1 to 3 The substation monitoring picture drawing method provided in the embodiment of the present application includes steps S11 to S14:

[0043] In step S11, the substation information of a to-be-monitored substation is acquired, and an xml template library of the to-be-monitored substation is established according to the substation information. The xml template library includes a device template library and a component template library.

[0044] It should be noted that, in order to solve the problem that the traditional professional drawing software such as CAD has certain requirements for industrial drawing capability, and if a large drawing or a complex logic configuration is to be processed, a high-performance computer needs to be equipped and sufficient human resources need to be invested; and in order to solve the problem that some picture recognition methods for design drawings or vendor drawings adopt computer vision technologies such as feature extraction and image recognition, and a plurality of machine learning algorithms are applied for feature-based image matching, and the steps are relatively complex and the scene adaptability is not strong, the present application forms an electrical diagram svg file based on the xml templates of basic devices and components and a position adjustment strategy, constructs a substation monitoring user interface by using a front-end technology, identifies a component ID attribute of an imported electrical diagram file, and listens to changes in real-time subscription data, so as to realize real-time display of closing, opening, alarming and network-related data.

[0045] Specifically, taking a main wiring diagram as an example, the device template library can include one or more of an outgoing line, a high-voltage bus, a low-voltage bus, a bus PT, a main transformer, a power collection line, a grounding transformer, a station transformer and a reactive power compensation device; and the component template library can include one or more of a circuit breaker, a disconnector and a grounding knife switch. The device template library and the component template library can both independently form an electrical diagram svg file, and the file can be opened and viewed through a code editor, a browser or a professional drawing software. It can be understood that the types of devices or components included in the device template library and the component template library in other embodiments are also adjusted according to actual needs.

[0046] Step S12, according to the xml template library of the substation to be monitored, the monitoring picture of the substation to be monitored is divided into image grid, and the image grid matrix is obtained.

[0047] Specifically, according to the substation design file, design drawing or manufacturer's drawing of the substation to be monitored, the monitoring picture of the substation to be monitored is determined; according to the xml template library of the substation to be monitored, the monitoring picture is divided into image grid, and the image grid matrix is obtained, and the image grid matrix is defined as R(m,n); wherein m takes the number of image grid rows, and n takes the maximum value in each row of image grid element. In addition, in this embodiment, the elements in the matrix can represent different devices with specific numbers, and each row is filled from the first element to the back, and the subsequent elements are replaced with 0 when the maximum element number is not enough.

[0048] Step S13, determining the position of each initial element in the image grid matrix and the position change logic of each element in the row.

[0049] Specifically, the position of each initial element in the image grid matrix is determined through the element position matrix, and the element position matrix is defined as S(m,2), which records the horizontal position and vertical position of the first element in the image grid matrix in the xml. The position change logic of each element in the image grid matrix is determined through the element position logic matrix, and if the devices of the same row elements follow the same position change rule, the element position logic matrix is defined as M(m,2), which represents the horizontal change step and vertical change step of each row position. It can be understood that if the devices of the same row elements do not follow the same position change rule, the rule can be further refined, and multiple matrices can be defined to describe the position change of each row.

[0050] Step S14, identifying the component ID with the listening attribute of the xml template library, generating the electrical diagram according to the image grid matrix, the position of each initial element in the image grid matrix, the position change logic of each element in the row, and the component ID, and obtaining the monitoring picture of the substation to be monitored according to the electrical diagram.

[0051] Among them, for the components with dynamic effect change in the template library such as circuit breaker, disconnecting switch and grounding knife switch, the classification of listening attribute is carried out, such as closing and opening, component color change and the like, and the component ID attribute is obtained by adding prefix or suffix to the related measuring point ID.

[0052] Specifically, properties of all devices and / or components in a monitoring picture of the to-be-monitored substation are set through cyclic iteration; xml templates of individual devices and / or components are combined for picture layout to form the electrical diagram. The electrical diagram includes a main electrical diagram and sub electrical diagrams, and the main electrical diagram can reflect connection relationship between devices and components and overall dynamics, and the sub electrical diagrams are used to reflect working states of corresponding components or devices in real time.

[0053] Further, svg files of the main electrical diagram and the sub electrical diagrams are embedded into a substation monitoring system of the to-be-monitored substation to view monitoring picture content; if positions of devices and / or components are not suitable, the step of determining positions of each row of initial picture elements in the image grid matrix and position change logic of each row of picture elements is returned to fine-tune until the picture layout meets requirements.

[0054] Further, the substation monitoring picture drawing method can further display, in real time, point information and control information of a monitoring device to a monitoring picture of the to-be-monitored substation when receiving a point ID information subscription instruction of the monitoring device.

[0055] For example, please refer to Figure 2 , a substation electrical diagram, in which components mainly include circuit breakers (represented by rectangles), busbars (represented by horizontal straight lines), and general lines (represented by vertical lines). Note: this diagram is only used for example, and an actual electrical diagram is more complex.

[0056] According to a work flow:

[0057] First, assuming that a final monitoring picture resolution is 1920*1080, and assuming that a circuit breaker icon height H and width W are respectively 80 and 40, a busbar length L is 800, and a general line length K is 80, an xml template library is established.

[0058] Further, the monitoring picture is divided into an image grid matrix according to the xml template library of the to-be-monitored substation, and a matrix R(m,n) is defined, so that m is 11 and n is 16.

[0059] A number 1 represents a circuit breaker, a number 2 represents a busbar, and a number 3 represents a general line, so that

[0060]

[0061] Further, the position of each initial primitive in each row of the image grid matrix is determined by the primitive position matrix, and the primitive position matrix is defined as the horizontal position and vertical position of the primitive corresponding to the first element in each row (i.e. all elements in the first column of R) in S1(m,2) record R. After determining the position of the first element in the first row, the positions of other elements can be obtained according to some symmetry relations, which need to be planned in advance through a sketch or a drawing software.

[0062]

[0063] Similarly, the horizontal unknown and vertical position of the primitive corresponding to all elements in the i-th column of R can be represented by S i .

[0064] Further, the position change logic of each primitive in each row of the image grid matrix is determined by the primitive position logic matrix, and the primitive position logic matrix M(m,2) is defined to represent the horizontal change step and the vertical change step of the position of each row,

[0065]

[0066] It can be deduced that

[0067] S i =S i-1 +M

[0068] Further, the point ID of all circuit breakers is associated, and the real-time state data of the device can be obtained through this attribute in the interface display in the subsequent steps.

[0069] Then, according to the recursive formula S i =S i-1 +M, the value of S i i=2,…n. can be determined, i.e. the position of all components in the electrical diagram, and thus the basic primitives in the xml template library are combined to form a complete electrical diagram.

[0070] Further, according to the above steps, the electrical diagram shown below can be obtained, and it can be found that the positions of the 9th-16th elements in the last two rows need to be adjusted, at which time the step of determining the position change logic of each primitive in each row of the image grid matrix can be returned, and the primitives that need to be adjusted are perfected through the following recursive loop.

[0071]

[0072] S i =S1+(i-1)*M+N

[0073] Finally, subscribe to all the circuit breaker associated with the point ID information, listen to the change of subscription ID data to realize the real-time display of the device state, such as the circuit breaker in this example, the received subscription value is 1, which shows the red closing state, and the value is 0, which shows the green opening state.

[0074] It can be understood that the present application solves the problem of large software mapping workload and high professional requirement in the prior art; realizes automatic arrangement of sub-devices of a substation monitoring picture, real-time state and data display of the substation monitoring picture, and organic fusion with other monitoring pictures to construct a large power application, and meets actual application requirements.

[0075] The above substation monitoring picture drawing method first acquires substation information of a to-be-monitored substation, and establishes an xml template library of the to-be-monitored substation according to the substation information; wherein the xml template library comprises a device template library and a sub-device template library; image raster division is performed on a monitoring picture of the to-be-monitored substation according to the xml template library of the to-be-monitored substation, to obtain an image raster matrix; the position of each initial graph element in each row of the image raster matrix and the position change logic of each graph element in each row are determined; a sub-device ID with a listening attribute in the xml template library is identified; an electrical diagram is generated according to the image raster matrix, the position of each initial graph element in each row of the image raster matrix, the position change logic of each graph element in each row, and the sub-device ID; and a monitoring picture of the to-be-monitored substation is obtained according to the electrical diagram. Compared with the prior art, the present application can draw a substation monitoring main picture and sub-pictures, and can embed a drawing file into a digital monitoring system to realize real-time display of closing, opening, alarming, and network-related data, and meets actual application requirements.

[0076] It should be understood that, although each step in the above flowchart is shown in sequence according to the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless explicitly stated herein, there is no strict order limitation for the execution of these steps, and these steps can be executed in other orders. Moreover, at least part of the steps in the above flowchart can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or sub-steps or stages of other steps.

[0077] Referring to Figure 4 The present application also provides a substation monitoring picture drawing device, which comprises:

[0079] It should be noted that, in order to solve the problem that the traditional professional drawing software such as CAD has certain requirements for industrial drawing capability, and if a large drawing or a complex logical configuration is to be processed, a high-performance computer needs to be equipped and sufficient human resources need to be ensured; and other picture recognition methods for design drawings or vendor drawings adopt computer vision technologies such as feature extraction and image recognition, and various machine learning algorithms are applied for feature-based image matching, and the steps are relatively complex and the scene adaptability is not strong. The present application forms an electrical diagram SVG file based on the XML template of the basic equipment and the component and the position adjustment strategy, constructs a substation monitoring user interface by using a front-end technology, identifies the component id attribute of the imported electrical diagram file, and listens to the change of real-time subscription data to realize real-time display of closing, opening, alarm and network-related data.

The position change logic of each image element in each row of the image grid matrix is determined through an image element position logic matrix, and the image element position logic matrix is defined as M(m, 2) to represent the horizontal change step and vertical change step of the position of each row. It can be understood that if the devices of the image elements in the same row do not follow the same position change rule, the rule can be further refined to define multiple matrices to respectively describe the position change of each row.

[0085] A monitoring picture generation module 24 is configured to identify the component ID with a monitoring attribute in the xml template library, generate an electrical diagram according to the image grid matrix, the position of each initial image element in each row of the image grid matrix, the position change logic of each image element in each row, and the component ID, and obtain the monitoring picture of the to-be-monitored substation according to the electrical diagram.
