The method realizes the fast consistency of the graphs and eliminates unsafe events caused by equipment errors.
Background
At home and abroad, power Distribution Automation (DA) is not a new concept at present, and is a comprehensive information management system integrating computer technology, data transmission, control technology, modern equipment and management, and the purpose of the system is to improve the reliability of power supply, improve the quality of electric energy, provide high-quality service for users, reduce the running cost and lighten the labor intensity of operators. In industrially developed countries, power distribution system automation is widely paid attention to, and power distribution system automation in the countries such as the united states, japan, germany, france and the like has formed a power distribution network management system (DMS) integrating systems such as substation automation, feeder sectionalizing switch measurement and control, capacitor bank regulation control, user load control, remote meter reading and the like.
Distribution automation can be greatly improved in scheduling operation control and fault processing capacity, distribution network operation maintenance and overhaul capacity, power grid power supply reliability and power supply quality are improved, accident handling time is shortened, power outage range is reduced, running economy of a power system is improved, running maintenance cost is reduced, economic benefit of enterprises is improved, management level and working efficiency of the whole distribution system are improved, user service level is improved, and the like. However, the method is a systematic engineering, and involves a plurality of links such as planning, design, construction, research and development, operation and maintenance, application and the like, so that a plurality of professions are needed to cooperate and integrate, the comprehensive technical application is not a single fight, and the construction difficulty is very high. Even after successful construction and operation, the construction is not once and forever, and the practical difficulty is higher. The distribution network directly faces to the specificity of users, changes such as new throw abnormal retirement renaming and the like are frequent, and the later maintenance workload of the system is very large; meanwhile, the technical level, development environment and mechanism matching of the industry do not reach ideal and practical heights at present, and various obstacle influence constraints exist, so that maintenance cannot keep up, the drawings are inconsistent, and the final power distribution automation system cannot be used and is paralyzed.
Disclosure of Invention
The invention aims to solve the technical problems in the current state of the art, namely, a main operation mode of the power distribution automation master station side for the maintenance of a pattern or a manual maintenance mode of the master station is adopted, but because the power distribution network equipment is huge, a large number of single line diagrams, station room diagrams, ring network diagrams and the like are required to be drawn for meeting the actual operation of the distribution. Along with the increase of the system scale, the master station side manually maintains the graphic model, so that the graphic model cannot be carried, the correct synchronization cannot be ensured, the practical level and the quality of power distribution automation are affected, and the aim is to provide a graphic forming method of PMS model graphic elements of the power distribution automation system, so that the problems are solved.
The invention is realized by the following technical scheme:
the method for mapping the PMS model primitives of the power distribution automation system is characterized by comprising the following steps of: s1: after the distribution automation system receives the distribution line abnormal notification, the pattern file is imported into the PMS model, and after the pattern file is imported into the PMS model, the mode diagram after abnormal operation is imported; s2: after a mode diagram is imported into the PMS model, automatic graphic primitive superposition is carried out, corresponding abnormal automatic equipment is found on the basis of the mode diagram of the step S2, and automatic graphic primitives are drawn on the automatic equipment; s3: after the automatic graphic element is drawn, the graphic element is associated with the PMS model through a retriever, and finally, the front telemetry of the dynamic graphic element is added beside the automatic equipment, and the front telemetry signaling and the protection signal for the association of the protection graphic element are added.
At present, after distribution automation operation, three modes are mainly adopted for maintaining a master station pattern, one is a pattern mode of using IEB buses to interactively use the front end of the PMS, and the other is a pattern mode of manually maintaining the master station. Yet another is the automated patterning that is under development.
One is to use the IEB bus to interactively use PMS in a graphics fashion. The source end maintenance and global sharing are ideal states of power distribution automation, are necessary conditions for expanding application and power grid pattern source end maintenance, and are currently in deep research and development. The existing method has the problems of single function, unidirectional pushing, non-uniform graphics primitive, non-uniform graphics, unreasonable labels, unreasonable layout and the like, and is difficult to bear the heavy duty of automatic intelligent management and development of power distribution.
The other is a manual maintenance pattern mode of the master station. The bottleneck of the PMS pattern is caused by the IEB bus interaction, so that the generation of the malformed pattern of the master station manual maintenance pattern is promoted. The working mode is not scientific and advanced and does not accord with the current overall architecture thought. The problems that the repeated construction of the graph model increases the workload of automatic manual maintenance, shifts the center of gravity of automatic operation, loses participation among front end departments, lacks an audit confirmation link, has low accuracy, and cannot realize automatic closed-loop management of a real equipment change flow exist.
In addition, an automatic imaging mode is adopted, and because of the defects of the methods, the method which is enthusiastically researched and developed by various large companies at present is an automatic imaging mode, namely, a model of a PMS source end is utilized to automatically generate a graph. Problems found in practical use are: the equipment name layout is unreasonable, the equipment interconnection feeder layout is unreasonable, too many cross lines exist, the feeder layout needs to be optimized, the main configuration association cannot be realized through a 10kV outgoing line breaker, the automatic mapping program cannot recognize that the breaker starts to generate a graph for a re-imported feeder model after program updating, and the like. Therefore, this method has not been put into practical use, and is currently under deep development.
In the application, the adopted imaging mode is improved on the prior art, and the problems are effectively solved by a PMS model, a mode graph and an automatic graphic element of a three-element imaging method of a power distribution automation system, and the mode graph is explained by nouns firstly: the method is that the latest drawing of the distribution network line which is specially issued after the distribution network equipment is abnormal in a dispatching operation mode, namely, the drawing after the professional audit of the equipment maintenance unit in the OMS system, such as the management, marketing, operation and inspection, regulation and control, protection and the like, is initiated by the equipment maintenance unit in the middle. The mode specialty is the specialty of the local regional power grid operation mode returns to the mouth the management department, participate in the start-up operation work of new, change, tear-down, overhaul, technology change equipment, the drawing that the mode specialty provided is the drawing that most accords with the production practice at present. The PMS model is a model which is pushed from the PMS2.0 to the distribution network automation system by the operation checking department through the IEB bus for checking, and the graph of the PMS cannot be checked for use, but the model can be used. An automation graphic element is a graphic element of equipment for drawing by an automation system.
The method is to string the PMS2.0 model of the specialized drawing and operation checking part in the mode by using an automatic graphic element and present the model in an automatic system, so that the aim of simple and accurate drawing is fulfilled. After the method is adopted, a large number of non-automatic equipment maintenance problems are solved, and the automatic operation and maintenance personnel will not reproduce the graphic model, but only the carrier of the graphic model.
Further, the pattern diagram importing of the step S1 includes the following steps：S A1 : firstly, carrying out format replacement, carrying out format conversion on the distribution network circuit diagram subjected to the transaction provided by the download dispatcher, and converting the format into a JPG format; s is S B1 : then, the adjusted JPG circuit diagram is imported into a current workstation, and the JPG circuit diagram can be distributed to all workstations by executing a discover password at a Linux terminal; s is S C1 : and (3) entering a distribution network automation system, creating a distribution network single line diagram, importing the distribution network line diagram after abnormal movement into a background patch, scaling the background patch, and synchronously locking the background patch and an automation graphic element.
Further, the operation selection of the retriever in the step S3 is divided into three layers, namely a surface layer, an equipment layer and an equipment attribute layer, the equipment names are corresponding to the surface layer, the equipment layer corresponds to the equipment installation position, and the equipment attribute layer matches the basic attribute of the equipment.
Further, a power distribution automation master station is arranged in the power distribution automation system, and graph and data interaction is carried out between the power distribution automation master station and the PMS model through an IEB bus.
Further, the pattern data is sent to the distribution automation master station by the PMS model, enters a bus switch of the distribution automation master station through a firewall, goes to a three-zone switch through a three-zone information exchange bus server and goes to a one-zone information exchange bus server and a pattern debugging server through a reverse isolation device.
Further, the step of importing the graphic model data in the step S1 into the PMS model includes: s is S A2 : opening a graphic model verification importing tool in the PMS model, verifying graphic model data, performing the next step after the graphic model data are verified to be qualified, and reporting errors after the graphic model data are not verified to be qualified; s is S B2 : selecting a line to be imported, importing qualified data into a corresponding line, automatically guiding a graph, and adding or deleting a verification model and equipment in the PMS; s is S C2 : and after the graph is successfully guided, opening a database for browsing, and confirming that the graph mode data is in the designated area.

1. the invention discloses a patterning method of PMS model primitives of a power distribution automation system, wherein the existing pattern maintenance mode needs at least three days, and after an innovative method is adopted, automation personnel only need to implant pattern drawings, and maintenance work is developed in the aspect of mainly maintaining automation equipment; because the maintenance conditions of all the areas are different at present, more staff in some areas can realize real-time update of the distribution network, fewer staff in other areas can only be used for annual or semi-annual update, and the distribution drawing lines and the actual lines are possibly not unified during construction, accidents are easily caused, and after implementation, the situation that the distribution network staff is seriously insufficient can be fundamentally solved, and safety accidents caused by insufficient pattern maintenance are avoided;
2. according to the method for forming the PMS model graphic element of the power distribution automation system, equipment can be effectively monitored after the power is applied, the consistency and the action performance of the graphic can be completely ensured, and the equipment can be accurately positioned, isolated and supplied with power after the equipment fails. The social benefit is greatly improved;
3. the mapping method of the PMS model graphic element of the distribution automation system completely keeps the consistency of the distribution network single line diagram and the mode graphic interface, and meets the requirement of consistency of distribution and adjustment diagrams; because the mode diagram is a finished product from front-end marketing, operation inspection and audit of several major regulations. Therefore, the consistency of the graph can be completely ensured, meanwhile, the previous drawing maintenance of all equipment of the whole line is changed into the drawing maintenance of the automatic equipment only, the workload is reduced, and the efficiency and the quality of corresponding work are greatly improved.
4. According to the mapping method of the PMS model graphic element of the power distribution automation system, the graphics can be enlarged or reduced for viewing according to the requirement, meanwhile, the automation terminal equipment is arranged at the position of the corresponding graphic equipment in a color obvious mode, the state of the equipment is presented in real time through remote signaling and remote sensing, if the detailed state information is required to be viewed, the equipment can be clicked by a right click, real-time data can be selected, and all remote signaling and remote sensing of the equipment can be seen; if the ring main unit and the branch box need to be operated, clicking the name of the equipment, entering a station room diagram operation interface, effectively avoiding misoperation and ensuring safe operation of the power grid.
5.

Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present invention and the descriptions thereof are for illustrating the present invention only and are not to be construed as limiting the present invention.
Examples
As shown in fig. 1, a method for mapping PMS model primitives of a power distribution automation system is characterized by comprising the following steps: s1: after the distribution automation system receives the distribution line abnormal notification, the pattern file is imported into the PMS model, and after the pattern file is imported into the PMS model, the mode diagram after abnormal operation is imported; s2: after a mode diagram is imported into the PMS model, automatic graphic primitive superposition is carried out, corresponding abnormal automatic equipment is found on the basis of the mode diagram of the step S2, and automatic graphic primitives are drawn on the automatic equipment; s3: after the automatic graphic element is drawn, the graphic element is associated with the PMS model through a retriever, and finally, the front telemetry of the dynamic graphic element is added beside the automatic equipment, and the front telemetry signaling and the protection signal for the association of the protection graphic element are added. When the notification of the network line transaction is received, we start the mapping work. First, PMS model import is performed. Before the PMS model is imported, the condition of an IEB bus has to be said, and according to the requirements of national network companies, departments such as production, scheduling and the like, namely a distribution network picture can be realized, the aim of unique source end and global sharing of distribution network data can be achieved, and Mianyang companies deploy the IEB bus between PMS2.0 and a distribution automation master station to realize the picture-model interaction function. The flow of the PMS2.0 and the power distribution automation master station graph mode information interaction is as follows: and generating a pattern by the PMS2.0, interactively transmitting the pattern to an automatic distribution network system through an IEB bus, checking and importing the pattern through a pattern checking tool, receiving the pattern after the tool checking is passed, and commissioning the pattern after the pattern checking is performed on a system graphical interface. The hardware architecture is as shown in fig. 1: the pattern file is pushed by the PMS terminal, enters the distribution network automation system bus switch through the firewall, goes to the three-zone switch through the three-zone information exchange bus server, and goes to the one-zone information exchange bus server and the pattern debugging server through the reverse isolation device. Through the IEB bus bridge, the aim of uniformly using PMS source end graph mode by the distribution network automation system is fulfilled. Then, the graphic is imported, and the operation of the mode graphic importing system is divided into three steps, namely: format conversion, lead-in distribution and patch implantation. The working method comprises the following specific operations: firstly, downloading the latest distribution network circuit diagram after the transaction provided by the scheduling mode specialty, wherein the CAD format drawings are provided by the general mode specialty, and the CAD format is required to be converted into the JPG format. The method is that mini CAD software is used, after the software opens the latest circuit diagram, clicking the icon at the upper left corner of the software to convert into a picture pops up conversion settings and selects: line color setting: black and white, background color settings: white, definition setting: in general, line width setting: closing line width, setting a lead-out area: and (3) performing frame selection and derivation, and after the points are determined, converting the CAD-format line graph into a JPG-format line graph. Of course, other format conversion software operations may be selected. This software is batch-switchable, and the efficiency is higher if batch direct-switching software is used. Of course, if the mode specialty is a PDF format circuit diagram, only the PDF-to-picture software is needed to perform format conversion, and only the mode specialty circuit diagram is converted into a picture. Then, the adjusted JPG line graph is imported into the current workstation, (the open3200 system is a back_pixmap folder, the D5200 system is a data/graph/image folder), and the JPG line graph can be distributed to all workstations by executing a discover password on the Linux terminal. Entering a distribution network automation 3200 system, creating a distribution network single line diagram, and clicking in a system attribute editing frame: the background patch is implanted in a patch mode by selecting the mode diagram which is just edited, and attention should be paid to selecting a zoom mode so as to ensure that the later graphic zoom-in and zoom-out and the automatic graphic primitive are synchronously locked. This procedure, when studying the innovative method, is broken down for two weeks, and the self-contained attribute frames in the system are tested one by one and found finally. This parameter setting is particularly important because the default attribute of the system drawing is "tiling" and primitives will not separate as graphics shrink or enlarge.
In the folder (open 3200 system is back_pixmap folder, D5200 system is data/graph/image folder), looking up the high-width attribute of the line graph, correspondingly filling in the high-width data in the system line graph attribute editing frame, that is, the size of the graph is consistent with the size of the JPG graph, clicking the network for storage, filling in file names, file types, associated factory stations and the like, for example, the file names are as follows: first line, file type: line single line diagram, belonging to the application: all the stations are checked, and the stations are associated: the upper siphon line is associated, so that the mode diagram is implanted into the distribution network automation system.
The rest is to perform automatic primitive superposition, and the step comprises three steps of operations: drawing primitives, retrieving equipment and measuring links. 1) Drawing primitives
On the basis of the mode diagram, the corresponding automation equipment is found, namely the automation terminal which is subjected to automation transformation, and the automation graphic elements are drawn on the automation equipment: clicking on the off-station primitive on the left side of the drawing window, selecting correspondingly in the list: and selecting the primitives such as the distribution transformer, the off-site switch, the off-site bus and the like, then ejecting a primitive selection frame, selecting proper equipment primitives in the primitive selection frame, drawing the equipment primitives on corresponding automatic equipment one by one, clicking a primitive attribute editing frame, and adjusting the rotation angle, naming rules, dynamic coloring and the like of the equipment primitives.
2) Search device
The retriever is then opened by clicking the right button on the drawing window, and the graphical element is associated with the PMS model. The retriever operation selects three layers: a surface layer, a device layer and a device attribute layer. Such as a pole-on switch, skin selection: and the equipment layer selects a switch point on the column of the line to drag to the switch graphic element on the graph, the corresponding switch graphic element changes color, and the related operation is completed. We associate PMS models with retrievers for all automation equipment primitives on the graph.
3) Measurement link
Finally, adding a measurement dynamic graphic element association upper front remote measurement, a protection graphic element association upper front remote signaling and a protection signal beside the automation equipment, and adding a link on a graph: including return home page, FA graph, station-room graph, tie line, etc.
Through the three large steps, the mode 'dead' graph and the distribution automation graphic element are organically fused to form a new distribution network single line graph with the automation attribute 'alive'.
