Technical Field

[0001] The present invention belongs to the field of secondary maintenance of substations, and particularly relates to a method for automatically filling out a secondary safety measure ticket for a conventional substation. Background Art

[0002] At present, the power system begins to show the characteristics of comprehensivedigitization, networking, integration, and informatization. As an effective measure to ensure the safe operation of electrical equipment and prevent accidents, it is a development trend to improve the filling method of substation secondary safety measure tickets.

[0003] However, most methods for generating substation secondary safety measure tickets are as follows: searching for substation secondary drawings and manually inputting them into the work ticket; resulting in slow filling speed and low accuracy.

[0004] The existing method of generating substation secondary safety measures by parsing SCD files or SPCD files only solves the safety measure problems of optical fiber connection circuits in intelligent substations and does not include the safety measure problems of cable circuit parts; especially, there is a lack of necessary implementation methods for the secondary safety measures of conventional substations with a large number of cable connection circuits. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for automatically filling out a secondary safety measure ticket for a conventional substation in view of the above problems existing in the prior art, improve the filling efficiency of the substation secondary safety measure ticket, and ensure the correctness of the filling of the substation secondary safety measure ticket. The cable connection relationship between cabinets is visually displayed through a visualization software, the process of substation secondary safety measures is simplified in the form of software operation, and the results of secondary safety measures can be visually displayed. By quickly and accurately automatically filling out the substation secondary safety measure ticket, the work efficiency of on-site operation and maintenance personnel is greatly improved, and the filling difficulty of the substation secondary safety measure ticket is reduced.

[0006] The above object of the present invention is achieved by the following technical solutions:

[0007] A method for automatically filling out a secondary safety measure ticket for a conventional substation includes the following steps:

[0008] Step 1: Establish a substation secondary physical circuit information model file according to the substation secondary CAD drawings;

[0009] Step 2: Parse the substation secondary physical circuit information model file in Step 1 and visually present the information in the substation secondary physical circuit information model file in a visualization interface;

[0010] Step 3: In the auxiliary safety measure interface, perform secondary safety measure operation settings;

[0011] Step 4: Automatically identify the secondary safety measure results in the auxiliary safety measure interface according to the secondary safety measure rules.

[0012] Step 5: Automatically fill in and generate the secondary safety measure ticket according to the filling rules of the secondary safety measure ticket for the substation.

[0013] As described above, the establishment of the secondary physical circuit information model file for the substation in Step 1 includes:

[0014] Obtain the cabinet and device description information from the cabinet layout diagram in the secondary CAD drawings of the substation; obtain the description information of pressure plates, air switches, and reset buttons, etc. from the in-cabinet component diagram in the secondary CAD drawings of the substation; obtain the description information of the in-cabinet cable connection relationship from the secondary schematic diagram in the secondary CAD drawings of the substation; obtain the terminal block description information, terminal block terminal information, and inter-cabinet cable connection relationship information from the terminal block diagram in the secondary CAD drawings of the substation, and generate the initial version of the secondary physical circuit information model file for the substation.

[0015] As described above, the visualization of the information in the secondary physical circuit information model file for the substation in Step 2 includes the following steps:

[0016] Based on the secondary physical circuit information model of the substation, use the inter-cabinet cable information between cabinets as the starting point for searching; search for all inter-cabinet cables connected to the outside of the cabinet, and according to the connection relationship of the inter-cabinet cables, find the terminal block terminal information at both ends connected by the inter-cabinet cable cores.

[0017] According to the in-cabinet cable connection relationship information, find the pressure plate information, air switch information, and device information connected to the terminal block terminals.

[0018] Visually display the above cabinets, inter-cabinet cables, inter-cabinet cable connection relationships, terminal block terminal information, pressure plate information, air switch information, and device information.

[0019] As described above, Step 3 includes the following steps:

[0020] The left list of the auxiliary safety measure interface displays the hierarchical structure of the secondary physical circuit information of the substation, and the hierarchical structure is displayed from the cabinet level to the device level.

[0021] Set the secondary safety measure mode selection in the auxiliary safety measure interface. The secondary safety measure modes include three types: protection verification mode, protection transformation accompanying outage cabinet non-verification mode, and protection transformation accompanying outage cabinet verification mode.

[0022] After the setting is completed, prompt the user to drag and select the cabinets or devices in the left list to the middle area. The dragging effects of the cabinets or devices are the same, and both are regarded as dragging the cabinets.

[0023] The middle area of the auxiliary safety measure interface is initially blank. After dragging the switchgear cabinet, a dotted line frame is used to enclose the devices inside the switchgear cabinet in the middle area, and the states and colors of all the devices inside the switchgear cabinet are kept consistent.

[0024] During the protection verification mode, no attribute selection is performed on the dragged switchgear cabinet. By default, the switchgear cabinets dragged to the central area are all protection verification switchgear cabinets. The central area shows the inter-cabinet cable connection relationships between the protection verification switchgear cabinets and other switchgear cabinets in the substation.

[0025] In the non-verification mode of the protection transformation accompanying outage switchgear cabinet and the verification mode of the protection transformation accompanying outage switchgear cabinet, by default, the first dragged switchgear cabinet is the transformation switchgear cabinet. When dragging another switchgear cabinet, it is necessary to select the attribute of the dragged switchgear cabinet as the transformation switchgear cabinet or the accompanying outage switchgear cabinet. If it is selected as the transformation switchgear cabinet, it will be placed together with the first dragged transformation switchgear cabinet. If it is selected as the accompanying outage switchgear cabinet, it will be placed separately from the first dragged transformation switchgear cabinet. That is, the transformation switchgear cabinet and the accompanying outage switchgear cabinet are placed separately at different positions in the central area, and their external cable connection relationships are respectively shown for the transformation switchgear cabinet and the accompanying outage switchgear cabinet, and the external cable connection relationship between the transformation switchgear cabinet and the accompanying outage switchgear cabinet is not shown.

[0026] The secondary safety measure rules in step 4 as described above include:

[0027] Rule 1: When the secondary safety measure mode is selected as the protection verification mode, all the current loop identifiers connected externally to the protection verification switchgear cabinet are marked as the disconnected state.

[0028] Rule 2: When the secondary safety measure mode is selected as the protection verification mode, all the voltage loop identifiers connected externally to the protection verification switchgear cabinet are marked as the disconnected state.

[0029] Rule 3: When the secondary safety measure mode is selected as the protection verification mode, all the switch quantity output loop identifiers between the protection verification switchgear cabinet and the opposite-side protection switchgear cabinet are marked as the disconnected state. The pressure plates in the switch quantity output loop are marked as the withdrawn state, and the common end in the switch quantity output loop and the corresponding terminal block terminals are marked as the disconnected state.

[0030] Rule 4: When the secondary safety measure mode is selected as the protection verification mode, all the monitoring signal loop identifiers between the protection verification switchgear cabinet and the opposite-side measurement and control switchgear cabinet are marked as the disconnected state.

[0031] Rule 5: When the secondary safety measure mode is selected as the protection verification mode, all the oscillograph loop identifiers between the protection verification switchgear cabinet and the opposite-side fault recorder switchgear cabinet are marked as the disconnected state.

[0032] Rule 6: When the secondary safety measure mode is selected as the non-verification mode of the protection transformation accompanying outage switchgear cabinet, secondary safety measure verification is performed on all the opposite-side switchgear cabinets of the transformation switchgear cabinet.

[0033] Rule 6: When the secondary safety measure mode is selected as the non-verification mode for protecting the modified standby screen cabinet, all DC air switches in the standby screen cabinet are marked as off;

[0034] Rule 7: When the secondary safety measure mode is selected as the verification mode for protecting the modified standby screen cabinet, perform secondary safety measure verification on all opposite-side screen cabinets of the modified screen cabinet:

[0035] Rule 8: When the secondary safety measure mode is selected as the verification mode for protecting the modified standby screen cabinet, the switch output circuit in the opposite-side protection screen cabinet of the standby screen cabinet is marked as off.

[0036] As described in step 5 above, according to the operation filling rules of the secondary safety measure ticket for the substation, the automatic filling and generation of the secondary safety measure ticket includes the following steps:

[0037] The secondary safety measure ticket for the substation is issued centered on the screen cabinet;

[0038] When the secondary safety measure mode is selected as the protection verification mode, each protection verification screen cabinet in the central area issues one secondary safety measure ticket;

[0039] When the secondary safety measure mode is selected as the non-verification mode for protecting the modified standby screen cabinet, each opposite-side screen cabinet of each modified screen cabinet in the central area issues one secondary safety measure ticket, and each standby screen cabinet in the central area issues one secondary safety measure ticket;

[0040] When the secondary safety measure mode is selected as the verification mode for protecting the modified standby screen cabinet, each opposite-side screen cabinet of each modified screen cabinet in the central area issues one secondary safety measure ticket, each standby screen cabinet in the central area issues one secondary safety measure ticket, and each opposite-side protection screen cabinet of each standby screen cabinet in the central area issues one secondary safety measure ticket;

[0041] After marking according to the secondary safety measure rules, combined with the secondary physical circuit information model file of the substation, obtain the model information in the marked state. The model information includes the loop number information on the cabinet-to-cabinet cable cores, terminal block terminal information, pressure plate information, and air switch information;

[0042] Automatically fill and generate the secondary safety measure ticket according to the obtained model information and the secondary safety measure operation template.

[0043] Compared with the prior art, the present invention has the following advantages and effects:

[0044] 1.

[0046] 3. The method of the present invention can automatically fill in and generate the secondary safety measure ticket for the substation, which improves the work efficiency of the secondary on-site maintenance personnel to a certain extent and provides safety guarantees for the on-site maintenance and renovation and expansion operations of the substation.

[0055] Step 1. Establish a secondary physical circuit information model file for the substation according to the secondary CAD drawings of the substation.

[0056] It should be noted that modeling the secondary physical circuit information of the whole station means describing all the switch cabinet information, all the inter-cabinet cables, all the devices and components inside the switch cabinets, and all the cable connection lines of the whole station according to the structure of the cable connection description file; including modeling the optical fibers and optical cables of the whole station. The structure of the secondary physical circuit information model file of the substation is as follows:

[0057] Please refer to Figure 1, define the substation secondary physical circuit information model file in XML format. A substation secondary physical circuit information model file includes:

[0058] A substation (SubStation) element that describes the name of this substation, the substation voltage level, and the location information of the affiliated area; multiple inter-cabinet cables (Cable) elements that describe the name, number of cores, the path of the switchboards connected at both ends, and the cable model of the inter-cabinet cables of the whole station; multiple substation compartments (Region) elements that describe the types and names of all compartments included in the substation; multiple inter-cabinet cable cores (Wire) elements that describe the number of each cable core, the path of the terminal numbers of the terminal blocks connected at both ends, and the usage description; multiple secondary circuit switchboards (Cubicle) elements that describe the numbers and names of all switchboards included in the substation compartments; multiple secondary devices (Unit) elements that describe the numbers, names, IEDname, manufacturers, device models, and types of all devices on the switchboards; multiple in-cabinet wires (InWire) elements that describe the name of the in-cabinet wires in the switchboard, the path of the connected components at both ends, and the usage description; multiple secondary device boards (Board) that describe the numbers, names, and models of all boards under the device; multiple secondary device terminals (Terminal) elements that describe the terminal numbers and terminal descriptions of all terminals on the secondary device boards; multiple secondary device combined components (Component) elements that describe the accessory name (name), accessory description (desc), type, and model; multiple secondary device connections (Connection) elements that describe the wire name, the connection path at both ends, the affiliated circuit number, and the usage description.

[0059] Obtain the switchboard and device description information from the switchboard layout diagram in the substation secondary CAD drawing; obtain the description information of pressure plates, air switches, and reset buttons from the in-cabinet component diagram in the substation secondary CAD drawing; obtain the description information of the in-cabinet cable connection relationship from the secondary schematic diagram in the substation secondary CAD drawing; obtain the terminal block description information, terminal block terminal information, and inter-cabinet cable connection relationship information from the terminal block diagram in the substation secondary CAD drawing;

[0060] Generate a substation secondary physical circuit information model file, and supplement and adjust it according to the actual situation.

[0061] Step 2: Parse the substation secondary physical circuit information model file in Step 1, and visually present the information in the substation secondary physical circuit information model file in the visualization interface. The information visually presented in the substation secondary physical circuit information model file includes the inter-cabinet cable connection relationship between switchboards;

[0062] Based on the secondary physical circuit information model of the substation, start the search from the inter - cabinet cable information between switch cabinets; search for all inter - cabinet cables connected to the outside of the switch cabinets. According to the connection relationship of the inter - cabinet cables, find the terminal information of the two - end terminal blocks connected by the cores of the inter - cabinet cables;

[0063] According to the information on the connection relationship of the in - cabinet cables, find the information on the pressure plates, air switches, and device information connected by the terminal block terminals.

[0064] After integrating the above - mentioned information, display it in a visual way.

[0065] Step 3: On the auxiliary safety measure interface, perform the operation settings for secondary safety measures;

[0066] The left - hand list on the auxiliary safety measure interface displays the hierarchical structure of the secondary physical circuit information of the substation, and the hierarchical structure is displayed from the switch cabinet level to the device level.

[0067] On the auxiliary safety measure interface, perform the selection settings for the secondary safety measure mode. The secondary safety measure mode includes three types: protection verification mode, protection transformation accompanying outage switch cabinet non - verification mode, and protection transformation accompanying outage switch cabinet verification mode.

By default, the switch cabinets dragged to the central area are all protection verification switch cabinets, and the inter - cabinet cable connection relationships between the protection verification switch cabinets and other switch cabinets in the substation are displayed in the central area.

[0071] In the protection transformation accompanying outage switch cabinet non - verification mode and the protection transformation accompanying outage switch cabinet verification mode, by default, the first dragged switch cabinet is the transformation switch cabinet. When dragging a switch cabinet again, it is necessary to select the attribute of the dragged switch cabinet as a transformation switch cabinet or an accompanying outage switch cabinet. If it is selected as a transformation switch cabinet, it will be placed together with the first dragged transformation switch cabinet. If it is selected as an accompanying outage switch cabinet, it will be placed separately from the first dragged transformation switch cabinet. That is, the transformation switch cabinet and the accompanying outage switch cabinet are placed separately in different positions in the central area, and the external cable connection relationships of the transformation switch cabinet and the accompanying outage switch cabinet are respectively displayed, and the external cable connection relationship between the transformation switch cabinet and the accompanying outage switch cabinet is not displayed;
