There may be 50-300 subscribers, 2-20 lines, 2-3 multilevel branches in the area. Due to site and cost consideration, the traditional simulation equipment only deploys 20 users, two branches and 2 lines, and cannot embody or restore the real characteristics of the station area to the maximum extent; the difficulty faced by the actual troubleshooting cannot be embodied, and the engineering tools are generally used for simple check, so that the processes of analysis, troubleshooting and treatment of the transformer area are lost, and the training obtaining skills cannot be applied to the actual environment. In the corresponding skill competition, the simulation capability is limited, and the skill level cannot be effectively compared.

Description of the embodiments
For a clearer understanding of the objects, technical solutions and advantages of the present application, the present application is described and illustrated below with reference to the accompanying drawings and examples.
As shown in fig. 1, an embodiment of the present application discloses a method for simulating a full-area fault, which includes:
A. the virtual system pre-stores the region file information, including user information, communication data information, network frame structure information and other related information of the region, which can be obtained from the power system.
B. During the fault simulation of the platform area, the virtual system establishes the user attribution relation of each path of total outgoing line according to the platform area file. If the total line number of the transformer area and the users are clear, establishing the original attribution relation of the transformer area, otherwise, randomly establishing attribution users according to the total line number set by the entity device, after establishing the total line user attribution relation, issuing each path of total line to the entity device, wherein the fault total line is included, and the attribution users and the lines corresponding to the total line are not issued to the entity device and are only displayed in a virtual system.
C. The entity device correspondingly presents all paths of total outgoing lines, and if the total outgoing lines of the entity device are larger than or equal to the total outgoing lines of the platform area, the entity device presents all paths of total outgoing lines at one time; if the total outlet of the entity device is smaller than the total outlet of the platform area, the entity device displays all the total outlets in a divided mode. The test tool tests on the physical device and judges which way of bus line the fault is under. At this time, the real line and the user under the total line are not issued, so that the testing tool can only test which total line has faults, and can not determine which specific branching line, which subsection and which user have faults under the total line, and the faults of the whole transformer area are avoided to be simply simulated and simply tested.
D. The virtual system makes a sectionalized topology for a line and a user under the sectionalized topology according to the selected fault total line, and can divide the sectionalized topology into a pole-to-section topology and a box-to-section topology according to the section type, and issues the sectionalized topology relationship to the entity device, including fault sectionalization, while the user in each section is still not issued to the entity device and is only displayed in the virtual system. Of course, in a special case, when the number of users in the segment topology of the platform is less than or equal to the number of users of the device, the virtual system may also send the corresponding user directly to the entity device.
E. The entity device correspondingly presents the subsection topological relation under the path total line, at the moment, if the number of users of the entity device is smaller than the number of users under the topology of the platform section, the users of the entity device are not matched with the users of the platform section, the users under each subsection topology are only displayed on the virtual system, at the moment, the testing tool only can test out which subsection has faults, and can not determine which line and which user have faults under the subsection, so that the real investigation method of the large user platform section of different types is simulated. Under special conditions, when the number of users in the sectional topology of the platform is smaller than or equal to the number of users of the devices, the entity device directly presents the users of the platform, and the testing tool can directly check the faults of the platform. In this step, if the fault total line checked in step C is wrong, the fault section will not issue physical devices in this step, and the test tool will not test the fault, indicating that the fault was checked.
F. After the total line fault range is reduced and the segment fault range is reduced, the final fault is locked into a segment, and at the moment, the rest of users and lines in the transformer area are reduced to the users and lines which can be met by the simulation unit of the physical device. And the virtual system transmits the rest lines and users under the section of the platform area to the entity device according to the selected fault section, wherein the rest lines and users comprise real faults and table number correspondence of the real users.
G. The entity device performs real presentation according to the issued line and user characteristics, including fault correspondence and table number correspondence, tests on the entity device through a testing tool, and judges the final fault point and fault reason. In this step, if the fault section checked in the step E is wrong, in this step, the real fault does not issue the physical device, and the test tool cannot test the fault, which means that the fault is checked.
As described above, the limited simulation units of the entity device match buses of different areas through limited buses, find out the bus fault and reduce the fault range of the area to below the fault bus; switching the simulation units below the physical device bus into a fault bus according to the segmentation topological relation of different areas, and reducing the fault range of the area to a certain segment after finding out the segmentation fault; when the simulation unit of the entity device meets the deployment requirements of the rest lines and users of the areas, the simulation unit of the entity device is switched into fault segmentation, and real faults are presented according to different areas, so that all simulation of the areas with different characteristics is completed;
the characteristics of each station area are different, and the station area faults are annihilated in the station area environment, and the method is consistent with a real station area fault troubleshooting method by firstly confirming a fault total line, then confirming a fault section under the total line, finally confirming whether a line fault in the section is a user fault or a fault reason, and is suitable for line loss faults, electric leakage faults and grounding faults caused by station area distribution equipment faults, distribution line faults and improper user electricity consumption.
Further, in the above total line fault confirmation, segment fault confirmation and segment internal fault confirmation processes, the faults can be directly analyzed and selected on the virtual system, when the analysis is correct, the faults are correspondingly issued to the entity device, the test tool can test the faults, and the analysis is correct; when the analysis is incorrect, the fault is not issued to the entity device, the test tool cannot test the fault, and the analysis error is indicated. The arrangement can meet the theoretical analysis simulation of the area.
The embodiment of the application discloses a full-area fault simulation method which is realized based on a full-area fault simulation device and comprises a virtual system and an entity device;
the virtual system comprises: the system comprises a file module, a setting module and an analysis module;
the entity apparatus includes: the system comprises an information module, a topology simulation unit, an element simulation unit and a fault simulation unit.
The virtual system is connected with the setting module and the analysis module through the file module, after the file module obtains the regional file information, the setting module sets a layered propulsion regional simulation scheme, and the analysis module analyzes the regional faults and transmits the regional simulation scheme and the fault characteristics to the information module of the entity device according to the layered propulsion rule; the entity device information module controls the topology simulation unit to simulate the platform region topology according to the platform region simulation scheme and the fault characteristics which are advanced in a layered manner, controls the element simulation unit to deploy simulation elements into the platform region topology, controls the fault simulation unit to simulate the fault characteristics into the platform region topology, and performs layered simulation presentation.
Further, the area file acquired by the file module of the virtual system includes: user information, exchange data information and grid structure information; the platform area simulation scheme set by the setting module comprises the following steps: a primary total line simulation scheme, a secondary total line lower segment simulation scheme, a specific user and line simulation scheme in a tertiary segment, and layered propulsion and layered simulation; the analysis module analyzes the fault of the platform area, which comprises the following steps: line loss fault, leakage fault, ground fault.
Further, the topology simulation unit of the entity device simulates the topology of the area, including: the topological characteristics of the pole transformer area and the topological characteristics of the box transformer area; an element simulated by an element simulation unit, comprising: the system comprises a summary table, a mutual inductor, a summary line, a distribution line and a user table; the fault characteristics simulated by the fault simulation unit comprise: line loss faults, leakage faults and grounding faults caused by station area distribution equipment faults, distribution line faults and improper power utilization of users.
In order to further explain the implementation steps of the full-area fault simulation method on the full-area fault simulation device, the following description is further made with reference to the accompanying drawings.
As shown in fig. 2, the entity device is provided with 1 simulation area, 4-way bus lines, 3 user groups, a plurality of lines and other simulation elements, and the topology characteristics can be switched by the topology simulation unit. As shown in fig. 2, which is only a diagram illustrating a method of full-area simulation, the number of actual simulation areas, the total number of lines, subscribers, lines, etc. may be freely set.
As shown in fig. 2, the virtual system sets the area as 4 total outgoing lines according to the area file, and after establishing a user attribution relationship of each total outgoing line, issues the 4 total outgoing lines to the entity device, including the fault total outgoing line. The testing tool tests the 4-way bus to determine that the fault is present, if none of the 4-way bus tests the fault, the fault is indicated to be on the power distribution room side, and the fault can be directly issued to the power distribution room side through the virtual system for fault confirmation in the next step; if the fault is determined to be below the total line, the next simulation is continued.
As shown in fig. 3 and 4, after confirming the fault total line, the fault total line 1 is taken as an example here. The virtual system sets a segment simulation scheme under the total line 1, and the entity device switches the user module into the segment topological feature of the pole transformer area shown in fig. 3 or the segment topological feature of the box transformer area shown in fig. 4 according to the segment simulation scheme, and accesses the fault total line 1. The testing tool tests and confirms fault segments in the segment topology, if the faults are in the segment 1 of fig. 3 or the segments 1 and 2 of fig. 4, the faults can be confirmed by directly issuing the faults through the virtual system because the segments belong to line fault characteristics; if the fault is in other segments, the next simulation is continued. Because other segments contain users, the specific fault point can be confirmed by checking the users, and when the number of users of the platform area to be simulated is large and the number of users of the entity device is limited, in order to prevent the real platform area test difficulty from being simplified by the entity device, the virtual system does not issue the platform area users, at the moment, the fault segments can only be determined first, then, the specific fault point method is confirmed in the fault to check, and meanwhile, the method is a standard and effective method for the platform area fault checking. Of course, if the number of users in the segment topology of the analog station is less than or equal to the physical device under special conditions, the fault and the users can be directly issued to the physical device for one-time checking and confirmation, thereby satisfying the small user station simulation in the whole station characteristics.
As shown in fig. 5, after validating the failed segment, the user group of the physical device may all hand in the failed segment. If the number of users of the entity device meets the number of users in the fault section of the platform region, the virtual system issues the rest lines and users under the fault section of the platform region to the entity device, wherein the rest lines and users comprise real faults and table number correspondence of the real users. If the total line fault range is reduced and the sectional fault range is reduced, when the number of the users of the platform area in the fault section is still larger than the number of the users of the entity device, the simulation of the fault range reduction can be carried out again, and when the number of the users of the platform area is smaller than or equal to the number of the users of the device, the virtual system confirms the real fault of the platform area and the users issue the entity device to carry out final fault confirmation.
If the number of users passing through the entity device meets the number of users in the fault section of the platform region, the virtual system issues the rest lines and users under the fault section of the platform region to the entity device, wherein the rest lines and users comprise real faults and table number correspondence of the real users.
In order to more clearly illustrate the full-area fault simulation, the following description is made in a quantitative manner. As shown in fig. 2, the simulation area of the physical device is provided with 4 total lines, 3 user groups, and each user group is provided with 9 users, and at this time, an area of 100 users needs to be simulated. Firstly, setting a total line, wherein a virtual system divides 100 households into 4 total lines corresponding to a physical device, each total line corresponds to 25 households, and at the moment, a testing tool tests on the 4 total lines of the physical device to determine which one of the 4 total lines the fault is in; then the virtual system carries out the subsection topology setting, the entity device sets 3 user groups as the pole transformer area characteristics or the box transformer area characteristics to be connected under the fault total line, meanwhile, the virtual system divides the 25 user areas into 8 users, 8 users and 9 users which respectively correspond to the user groups 1, 2 and 3 of the entity device, at the moment, the testing tool tests on the total line, the branch point, the user group 1, the user group 2 and the user group 3 of the entity device to confirm which subsection the fault is, if the fault subsection is the user group, the fault confirmation in the subsection is carried out, the number of users of the 8 users or the 9 users is less than or equal to that of the entity device, the virtual system transmits the users and the lines with the fault to each user group of the entity device, the user table number corresponds and the fault corresponds, and finally confirms the fault point and the fault reason through the testing tool. Under the same condition, if the number of users is 200, 50 users are left after the total line testing, 17 users and 16 users are left after the sectional testing, and the number of users of the entity device is less than the number of users of the platform region during the sectional internal testing, the test of a reduced range is required to be carried out again until the number of users of the platform region is less than or equal to 9 users, and the real characteristics are finally confirmed by the entity device.
Through the arrangement, fault simulation of various types of areas is realized, and the problems that a large number of users of the areas cannot be simulated by limited simulation units of the simulation device and the characteristics are different are solved. Of course, this illustration is merely one feature of the limiting condition, and the embodiments of the present application should not be limited by this exemplary condition, and the number of the total lines, the branch lines, the number of users, etc. of the similar entity devices are increased or decreased, which are all of conventional designs.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
