Description

Technical Field

[0001] This invention belongs to the field of relay protection commissioning of secondary systems in intelligent substations, and specifically relates to a method and equipment for sequential control verification of primary equipment based on the main wiring diagram. Background Technology

[0002] With the rapid development of society, the use of electricity is increasing dramatically. Investment in power grid infrastructure is constantly increasing, and the construction progress of the power grid needs to be accelerated. Especially with the rapid development of power industry technology, the commissioning of one-button sequential control testing for substations is cumbersome and has a short cycle. Within a limited time, it is almost impossible to complete the verification of the entire station's equipment status and operation ticket procedures, which has seriously affected the progress of infrastructure construction.

[0003] Currently, the workload for one-click sequential control testing is substantial, especially in verifying the sequential control ticket information for primary equipment, where accuracy is paramount. Generally, one-click sequential control host testing involves simulating protection and monitoring device trigger signals to coordinate with the sequential control host for operational ticket process testing and verification. Secondary system commissioning is time-sensitive and demanding, necessitating technological improvements to enhance the efficiency of intelligent substation secondary system commissioning and reduce personnel workload. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a method for sequential control verification of primary equipment based on the main wiring diagram.

[0005] To achieve the above-mentioned objectives, the specific solution of the present invention is as follows:

[0006] A method for sequential control verification of primary equipment based on the main wiring diagram includes the following steps:

[0007] Step 1: Parse the SLG main wiring diagram file exported from the monitoring backend to obtain the bay node information of the entire station. The bay node information of the entire station mainly includes: the description of the entire station bay node, the bay node ID, the voltage description of the bay node, the current description of the bay node, the wiring method of the bay node bus and the IEC61850MMS address information, as well as the description of all equipment nodes under each bay node, the equipment node ID, the virtual terminal IDs on both sides of the equipment node and the IEC61850MMS address information of each equipment node;

[0008] Step 2: Traverse all the interval node information obtained from the SLG main wiring file and simultaneously traverse all the interval node information obtained from the SCD file. Perform consistency matching and integration between the interval node information in the SLG main wiring file and the interval node information in the SCD file. Build a local database based on the consistent matching and integrated interval node information.

[0009] Step 3: Traverse all interval nodes in the local database, and generate the position status of each device node under the interval node based on the device node connection relationship, anti-misoperation logic rules, primary device and interval status definition;

[0010] Step 4: Generate an operation ticket based on the location status of each device node under the device state of the interval node. The operation ticket includes the interval node description, operation ticket description, operation item, execution conditions of the operation item, confirmation conditions of the operation item, and IEC61850MMS reference address information.

[0011] Step 5: Export the device status file and operation ticket file of the one-click sequential control host. Perform static verification of the device status file of the one-click sequential control host with the device status of the interval node in the local database. Perform static verification of the operation ticket in Step 4 and the operation ticket file exported from the one-click sequential control host.

[0012] Step 6: Generate a static verification report for the equipment status and a static verification report for the operation ticket.

[0013] As described above, step 2, consistency matching and integration, includes: performing consistency matching between the interval node ID in the SLG main wiring file and the interval node ID and device node ID in the SCD file, and integrating the matching interval node ID and device node ID.

[0014] As described above, the primary equipment and interval status includes:

[0015] Operating state: The switch is closed, the disconnector connected to the switch is closed, and the grounding switch connected to the switch is open;

[0016] Hot standby state: The switch is open, the disconnector connected to the switch is closed, and the grounding switch connected to the switch is open;

[0017] Cold standby state: The switch is open, the disconnector connected to the switch is disconnected, and the grounding switch connected to the switch is disconnected.

[0018] As mentioned above, the error prevention logic rules include:

[0019] Switch: When disconnected, there are no interlocking conditions; when closed, the grounding switch connected to it is in the open position.

[0020] Disconnector switch: When the disconnector switch is in operation, this compartment switch is in the open position. When the disconnector switch is closed, the grounding switch connected to the disconnector switch is in the open position.

[0021] Grounding switch: When the grounding switch is closed, the disconnector directly connected to the grounding switch or passing through the circuit breaker is in the open position.

[0022] As mentioned above, when the bay bus connection method of the bay node is the I bus connection method, the equipment status of the bay node includes: I bus running status, I bus hot standby status, and cold standby status;

[0023] When the bay bus connection method of the bay node is II bus connection method, the equipment status of the bay node includes: II bus operating status, II bus hot standby status, I bus operating status, I bus hot standby status, and cold standby status.

[0024] As described above, device-state static verification includes:

[0025] Comparison of interval node description and interval node device state:

[0026] If the interval node description and the device state of the interval node are consistent in the local database and the device state file, the interval node comparison is successful, and the device node comparison is then performed; otherwise, the interval node comparison fails.

[0027] Device node description comparison:

[0028] For successfully matched interval nodes, if a device node description corresponding to the local database is found in the device state file, the device node description is successfully matched, and the location and status of the device node are further compared; otherwise, the device node description comparison fails.

[0029] Device node location status comparison:

[0030] For a device node whose device node description is successfully matched, if the device node's location status in the device state file matches the corresponding device node status in step 3, then the device node's location status is successfully matched, and the IEC61850MMS reference address information is further compared; otherwise, the device node's location status is not matched.

[0031] Comparison of IEC61850MMS reference address information:

[0032] For a device node whose location status is successfully matched, if the IEC61850MMS reference address information in the device status file matches the corresponding IEC61850MMS reference address information in the local database, then the IEC61850MMS reference address information matching is successful; otherwise, the IEC61850MMS reference address information matching fails.

[0033] As mentioned above, static verification of operation tickets includes:

[0034] Comparison of interval node description and operation ticket description:

[0035] If the interval node description and operation ticket description of the operation ticket in step 4 match, the description comparison is successful, and the operation item comparison is performed; otherwise, the description comparison fails.

[0036] Comparison of operational items:

[0037] For operation tickets with successful descriptions, if the operation items in the operation ticket obtained in step 4 match the operation items in the operation ticket file, the operation item comparison is successful, and the comparison of execution conditions and confirmation conditions begins; otherwise, the operation item comparison fails.

[0038] Comparison of execution conditions and confirmation conditions:

[0039] For a successfully matched operation item, if the execution conditions and confirmation conditions of the operation item obtained in step 4 match the execution conditions and confirmation conditions of the operation item in the operation ticket file, then the execution conditions and confirmation conditions match successfully, and proceed to the IEC61850MMS reference address information comparison; otherwise, the execution conditions and confirmation conditions match unsuccessfully.

[0040] Comparison of IEC61850MMS reference address information:

[0041] For operation items where the execution conditions and confirmation conditions are successfully matched, if the IEC61850MMS reference address information of the operation item obtained in step 4 matches the IEC61850MMS reference address information of the operation item in the operation ticket file, then the IEC61850MMS reference address information matching is successful; otherwise, the IEC61850MMS reference address information matching fails.

Attached Figure Description

[0048] Figure 1 This is a schematic diagram of the process of this invention;

[0049] Figure 2 This is a schematic diagram of the I busbar connection in operation from the SLG main wiring diagram file. Detailed Implementation

[0050] To make the technical problems, technical solutions and beneficial effects of the present invention clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention.

[0051] A method for sequential control verification of primary equipment based on the main wiring diagram, the specific steps of which are as follows:

[0052] Step 1: Parse the SLG main wiring diagram file exported from the monitoring backend to obtain the bay node information for the entire station. The bay node information for the entire station mainly includes: the description of all bay nodes, bay node ID, bay node voltage description, bay node current description, wiring method of the bay node bus and IEC61850MMS address information, as well as the description of all equipment nodes under each bay node, equipment node ID, virtual terminal IDs on both sides of the equipment node and IEC61850MMS address information of each equipment node.

[0053] Parse the SCD file to obtain the MMS data model for the entire station. Extract the bay node information for each voltage level within the MMS data model. This bay node information mainly includes: bay node description, bay node ID, bay node voltage description, bay node current description, bay node busbar wiring method, and IEC61850 MMS address information (e.g., CE2201CTRL / CSWI3). ST Pos (stVal) also includes the description of all device nodes under each interval node, device node ID, virtual terminal IDs on both sides of the device node, and IEC61850MMS address information of each device node.

[0054] Step 2: Traverse all bay node information obtained from the SLG main wiring file and simultaneously traverse all bay node information obtained from the SCD file. Perform consistency matching between the bay node IDs in the SLG main wiring file and the bay node IDs in the SCD file. If the same bay node ID is found in the SCD file, further traverse the device node IDs of each matching bay node ID in both the SLG main wiring file and the SCD file. If the same device node ID is found in the SCD file, then integrate the matching bay nodes in both the SLG main wiring file and the SCD file, and integrate the device nodes under the matching bay nodes. By traversing and matching data in the above manner, the SLG main wiring diagram and the data in the MMS data model can be integrated to form a local database. The local data hierarchy is as follows: Interval node level (including interval node ID, interval node description, interval node wiring method, voltage and current description under the interval node and its IEC61850MMS reference address information) → Device node level (including device node ID, device node description, device node IEC61850MMS reference address information, and virtual terminal IDs on both sides of the device node).

[0055] Step 3: Traverse all interval nodes in the local database:

[0056] If the bay bus connection method of the bay node is I bus connection method, then the equipment status of this bay node is: I bus running status, I bus hot standby status, and cold standby status.

[0057] If the bay bus connection method of the bay node is II bus connection method, then the equipment status of this bay node is: II bus operating status, II bus hot standby status, I bus operating status, I bus hot standby status, and cold standby status.

[0058] Traverse the device nodes under each interval node (the typical device node ID is: switch (e.g.) Figure 2 CB), partition (such as) Figure 2 1G, 2G, 6G), ground knife (such as Figure 2 (5G, 8G, 9G). Based on the virtual segment information on both sides of each device node under the interval node, if any virtual terminal ID between two device nodes is the same, it indicates that the two device nodes are directly connected; otherwise, they are not directly connected. Based on the device node connection relationship, anti-misoperation logic rules, and primary device and interval status definitions, the position status of each device node under the interval node can be automatically generated.

[0059] The error prevention logic rule is as follows:

[0060] (1) Switch: When disconnected, there is no interlocking condition; when closed, the grounding switch connected to it is in the open position.

[0061] (2) Disconnect switch: When the disconnect switch is in operation, this compartment switch is in the open position. When the disconnect switch is closed, the grounding switch connected to the disconnect switch is in the open position.

[0062] (3) Grounding switch: When the grounding switch is closed, the disconnector that is directly connected to the grounding switch or passes through the circuit breaker is in the open position.

[0063] Primary equipment and interval status definition:

[0064] (1) Operating state: The switch is closed, the disconnector connected to the switch is closed, and the grounding switch connected to the switch is disconnected.

[0065] (2) Hot standby state: the switch is open, the disconnector connected to the switch is closed, and the grounding switch connected to the switch is disconnected.

[0066] (3) Cold standby state: The switch is open, the disconnector connected to the switch is open, and the grounding switch connected to the switch is open.

[0067] Based on the above rules, the position status of each device node under the automatically generated interval node is shown in Table 1. Table 1 is the position status table of each device node under the interval node in this embodiment.

[0068] Table 1

[0069]

[0070] Based on the location status of each device node in Table 1 and the IEC61850MMS reference address information of each device node in the local database, the location status of each device node in the device state under the interval node can be automatically generated.

[0071] For example: the device state of the interval node = the operating state of the mother node.

[0072] Location status of device nodes:

[0073] 332 switch^PC3521CTRL / CBCSWI1 ST Pos stVal=1,

[0074] 3321 switch^PC3521CTRL / QG1CSWI1 ST Pos stVal=1,

[0075] 3322 switch^PC3521CTRL / QG2CSWI1 ST Pos stVal=0,

[0076] 3326 switch^PC3521CTRL / QG6CSWI1 ST Pos stVal=1,

[0077] 3325 Grounding Switch^PC3521CTRL / QG5CSWI1 ST Pos stVal=0,

[0078] 3328 Grounding Switch^PC3521CTRL / QG8CSWI1 ST Pos stVal=0,

[0079] 3329 Grounding Switch^PC3521CTRL / QG9CSWI1 ST Pos stVal=0,

[0080] The information between “^” and “=" is the IEC61850MMS reference address information.

[0081] Step 4: Based on the location status of each device node under the device state automatically generated in Step 3 (i.e., Table 1), the corresponding operation ticket can be generated according to the wiring method of the interval bus.

[0082] If the bay busbar connection method is I busbar connection method, the generated operation ticket description includes:

[0083] (1) Switching from operating state to hot standby state of bus 1;

[0084] (2) The motherboard is switched from hot standby to cold standby.

[0085] (3) The motherboard is switched from operating state to cold standby state;

[0086] (4) Switch from cold standby to hot standby status;

[0087] (5) Switching from standby mode to operating mode of bus 1;

[0088] (6) Switch from cold standby state to motherboard operating state.

[0089] If the bay busbar connection method is II busbar connection method, the generated operation ticket description includes:

[0090] (1) Switching from operating state to hot standby state of bus 1;

[0091] (2) The motherboard is switched from hot standby to cold standby.

[0092] (3) The motherboard is switched from operating state to cold standby state;

[0093] (4) Switch from cold standby to hot standby status;

[0094] (5) Switching from standby mode to operating mode of bus 1;

[0095] (6) Switch from cold standby state to main engine operation state;

[0096] (7) Bus II is switched from operating state to hot standby state;

[0097] (8) Mother II is switched from hot standby to cold standby;

[0098] (9) The II motherboard transitions from operating state to cold standby state;

[0099] (10) Cold standby state to II motherboard hot standby state;

[0100] (11) Bus II is switched from hot standby to operating status;

[0101] (12) Switching from cold standby status to Bus II operating status;

[0102] (13) Transition from motherboard 1 operating state to motherboard II operating state;

[0103] (14) II mother running state to 1 mother running state.

[0104] Based on the description of the operation ticket above and the position status of each device node under the interval node in Table 1, an operation ticket can be generated. The operation ticket includes the interval node description, operation ticket description, operation item, execution conditions of the operation item, confirmation conditions of the operation item, and IEC61850MMS reference address information. The execution condition is the position status of the device node before the operation, and the confirmation condition is the position status of the device node after the operation.

[0105] For example: The operation items generated when the motherboard switches from operating state to cold standby state are:

[0106] The first step is to open the switch, provided the switch is in the closed position, there is voltage, and there is current. The confirmation condition is that the switch is in the open position, there is no voltage, and there is no current.

[0107] The second step is to open the 1G separator. The condition for this step is that the 1G separator is in the closed position. The confirmation condition is that the 1G separator is in the open position.

[0108] The third step is to open the 6G spacer. The condition for this step is that the 6G spacer is in the closed position. The confirmation condition is that the 6G spacer is in the open position.

[0109] Step 5: Export the device status file and operation ticket file of the one-click sequential control host. Perform static verification of the device status file of the one-click sequential control host with the device status of the interval node in the local database. Perform static verification of the operation ticket in Step 4 and the operation ticket file exported by the one-click sequential control host.

[0110] Device-state static verification includes:

[0111] Comparison of interval node description and interval node device state:

[0112] If the interval node descriptions in the local database and the device state file are inconsistent (you can iterate through the interval node descriptions in the device state file in the local database to see if there is a matching interval node description), or if the device state of the interval nodes in the local database and the device state file is inconsistent (you can iterate through the device state of the interval nodes in the device state file in the local database to see if there is a matching device state of the interval nodes), it indicates that the interval nodes in the device state file are incorrect, and the interval node comparison fails. If the interval node descriptions in the local database and the device state file are consistent, and the device state of the corresponding interval nodes in the local database and the device state file is consistent, it indicates that the interval nodes in the device state file are correct, the interval node comparison is successful, and further device node comparison can be performed.

[0113] Equipment node descriptions (switches, disconnectors, grounding switches, etc.) comparison:

[0114] For successfully matched interval nodes, if no device node description corresponding to the local database is found in the device state file, it indicates that the device state file is missing a device node description, and the device node description comparison fails. If a device node description corresponding to the local database is found in the device state file, it indicates that the device node description comparison is successful, and further comparison of the device node's location and status is performed.

[0115] Device node location status comparison:

[0116] For device nodes whose device node descriptions are successfully matched, if the device node's location status in the device state file does not match the corresponding device node status in step 3, the device node's location status comparison fails; if the device node's location status in the device state file matches the corresponding device node status in step 3, the device node's location status comparison succeeds, and further comparison of IEC61850MMS parameter address information is performed.

[0117] Comparison of IEC61850MMS reference address information:

[0118] For a device node whose location status comparison is successful, if the IEC61850MMS reference address information in the device status file is inconsistent with the corresponding IEC61850MMS reference address information in the local database, it indicates that the IEC61850MMS reference address information in the device status file is incorrectly associated, and the IEC61850MMS reference address information comparison fails. If the IEC61850MMS reference address information in the device status file is consistent with the corresponding IEC61850MMS reference address information in the local database, the IEC61850MMS reference address information comparison is successful, and the device node comparison is successful.

[0119] Static verification of operation tickets includes:

[0120] Comparison of interval node description and operation ticket description:

[0121] If the interval node description and operation ticket description of the operation ticket file and the operation ticket in step 4 do not match, the description comparison fails. If the interval node description and operation ticket description of the operation ticket file and the operation ticket in step 4 both match, the description comparison succeeds, and the operation item comparison is performed.

[0122] Comparison of operational items:

[0123] For operation tickets with successful descriptions, if the operation items in step 4 do not match the operation items in the operation ticket file, the operation item comparison fails; if the operation items in step 4 match the operation items in the operation ticket file, the operation item comparison succeeds, and the comparison of execution conditions and confirmation conditions begins.

[0124] Comparison of execution conditions and confirmation conditions:

[0125] For a successfully matched operation item, if the execution conditions and confirmation conditions of the operation item obtained in step 4 do not match the execution conditions and confirmation conditions of the operation item in the operation ticket file, the comparison of execution conditions and confirmation conditions will fail; if the execution conditions and confirmation conditions of the operation item obtained in step 4 match the execution conditions and confirmation conditions of the operation item in the operation ticket file, the comparison of execution conditions and confirmation conditions will succeed, and the process will proceed to the IEC61850MMS reference address information comparison.

[0126] Comparison of IEC61850MMS reference address information:

[0127] For operation items where the execution conditions and confirmation conditions are successfully matched, if the IEC61850MMS reference address information of the operation item obtained in step 4 does not match the IEC61850MMS reference address information of the operation item in the operation ticket file, then the IEC61850MMS reference address information matching fails; if the IEC61850MMS reference address information of the operation item obtained in step 4 matches the IEC61850MMS reference address information of the operation item in the operation ticket file, then the IEC61850MMS reference address information matching succeeds.

[0128] Step 6: Generate a static verification report for the equipment status and a static verification report for the operation ticket.
