Technical Field

[0001] This application relates to the field of power system topology analysis, and in particular to a method, device, equipment and medium for identifying the main wiring type based on bay topology. Background Technology

[0002] Existing substation anti-misoperation functions first establish a data model of each device and all its outgoing terminals by drawing the substation's main wiring diagram, thus determining the topological connection relationship. Based on this topological connection relationship, the bays, attributes, and main wiring types are then manually labeled. However, the workload of manually maintaining the data is enormous, and errors in manual labeling are inevitable, resulting in low accuracy in identifying the main wiring type. Summary of the Invention

[0003] This application provides a method, device, equipment, and medium for identifying main wiring types based on bay topology, aiming to improve the accuracy of main wiring type identification and provide accurate static data for substation error prevention rule judgment.

[0004] Firstly, this application provides a method for identifying the main wiring type based on a bay topology, including:

[0005] Establish the structural types and classification principles of switch bays, including 6 types of circuit breaker bays and 2 types of disconnector switch bays;

[0006] The switching equipment is classified into corresponding bay types, and the bay topology is constructed based on the switching bays and the equipment connected to them;

[0007] Based on the aforementioned interval topology, the wiring to be processed is preprocessed to obtain a set of switch interval types for the wiring to be processed.

[0008] Based on the wiring characteristics of various wiring types, and combined with the various switch interval type sets, wiring identification is performed to determine the main wiring type of the wiring to be processed.

[0009] In one embodiment, the determination of the structural types and classification principles of switch bays includes six categories of circuit breaker bays and two categories of disconnector switch bays, including:

[0010] Switch bays are classified into circuit breaker bays and disconnector bays. Circuit breaker bays are classified as type A, and disconnector bays are classified as type B.

[0011] The circuit breaker bay is characterized by having one circuit breaker as its core and including all disconnecting switches directly connected to the circuit breaker.

[0012] Based on the location of the disconnecting switches, circuit breaker bays are classified into six categories: A1 (only one circuit breaker); A2 (one circuit breaker with one disconnecting switch on one side); A3 (one circuit breaker with two disconnecting switches on one side); A4 (one circuit breaker with one disconnecting switch on each side); A5 (one circuit breaker with one disconnecting switch on one side and two disconnecting switches on the other side); and A6 (one circuit breaker with two disconnecting switches on each side).

[0013] The composition of a disconnector switch bay is characterized by: one disconnector switch as the core, which includes other disconnectors switches on both sides of it;

[0014] Based on the location of other disconnect switches, the disconnect switch bays are divided into two categories: one with only one disconnect switch, classified as category B1; and one with one disconnect switch on each side, classified as category B2.

[0015] In one embodiment, the process of identifying the main wiring type of the wiring to be processed based on the wiring characteristics of various wiring configurations and in conjunction with the various switch interval type sets includes:

[0016] If the set of switch interval types determines that the characteristics of a delta connection are met, then the main connection type of the connection to be processed is determined to be a delta connection.

[0017] The features of the angled connection are as follows: the A4 interval type set contains independent loops with the switch intervals connected end to end, and the independent loop contains at least three switch intervals; in the independent loop, a switch interval from the B1 interval type set is connected between every two switch intervals.

[0018] The wiring identification based on the characteristics of various wiring configurations, combined with the various switch interval type sets, determines the main wiring type of the wiring to be processed, including:

[0019] If, based on the set of switch interval types, it is determined that the wiring characteristics conform to 3 / 2 or 4 / 3, then the main wiring type of the wiring to be processed is determined to be 3 / 2 or 4 / 3 wiring.

[0020] The 3 / 2 or 4 / 3 wiring characteristics are as follows: there are at least two busbars; the number of strings consisting of all switch bays between the two busbars is at least two, wherein the switch bays are bays from the A4 bay type set, A2 bay type set, A1 bay type set, and B1 bay type set; at least one string among all strings between the two busbars has three or four circuit breaker bays; if there are only two strings between the two busbars, then at least one busbar is not connected to a disconnecting switch bay.

[0021] If the maximum number of circuit breaker bays is 3, then the main wiring type is determined to be 3 / 2 wiring; if the maximum number of circuit breaker bays is 4, then the main wiring type is determined to be 4 / 3 wiring.

[0022] The wiring identification based on the characteristics of various wiring configurations, combined with the various switch interval type sets, determines the main wiring type of the wiring to be processed, including:

[0023] Identify the switch bays in the A1, A2, A4, and B1 bay type sets that have one end connected to the incoming and outgoing lines, and store the other end of the switch bay in the NQ set.

[0024] Store the common endpoints of all incoming and outgoing line intervals that meet the conditions in the A1 interval type set, the A2 interval type set, and the A4 interval type set into the BUSQ set. The conditions are: the incoming and outgoing line intervals are only connected to one incoming and outgoing line interval in the B1 interval type set, and the incoming and outgoing line names are different.

[0025] If one end of a non-incoming / outgoing line interval in the A1 interval type set, the A2 interval type set, and the A4 interval type set is connected to an endpoint in the BUSQ set and the other end is connected to an endpoint in the NQ set, then both endpoints are determined to be bridge busbars.

[0026] If the number of bridge bays of the bridge busbar is one, then the main wiring type of the wiring to be processed is determined to be ordinary bridge wiring.

[0027] If the number of bridge bays of the bridge busbar is two, and the two bridge bays have a common endpoint, then the main wiring type of the wiring to be processed is determined to be an expanded bridge wiring.

[0028] If all main transformer bays in the bridge connection are circuit breaker bays and all line bays are disconnector switch bays, then the main connection type of the connection to be processed is determined to be an external bridge connection.

[0029] If all main transformer bays in the bridge connection are disconnector bays and all line bays are circuit breaker bays, then the main connection type of the connection to be processed is determined to be an internal bridge connection.

[0030] The wiring identification based on the characteristics of various wiring configurations, combined with the various switch interval type sets, determines the main wiring type of the wiring to be processed, including:

[0031] Identify the switch bays in the A1 bay type set, A2 bay type set, and A4 bay type set that have one end connected to the incoming / outgoing line and the other end connected to the bus, and store all the bus in the BUS set;

[0032] If the busbar taken from the BUS set is not connected to the switch bay in the B1 bay type set, then all the incoming and outgoing bays of the taken busbar are determined to form a single busbar, and the main wiring type of the wiring to be processed is determined to be a single busbar wiring.

[0033] After the analysis of all busbars in the BUS set is completed, all single busbar connections are stored in the BUS-Single set, and the non-incoming / outgoing line bays in the A1 bay type set, the A2 bay type set, the A3 bay type set, the A4 bay type set, the A5 bay type set, the A6 bay type set, the B1 bay type set, and the B2 bay type set are determined.

[0034] If the two ends of a non-incoming / outgoing line bay or the two ends of a loop consisting of two non-incoming / outgoing line bays connected in series are connected to two busbars in a BUS-Single set, and the two busbars are located on both sides of a circuit breaker, then the main wiring type of the wiring to be processed is determined to be a single busbar segmented wiring.

[0035] The wiring identification based on the characteristics of various wiring configurations, combined with the various switch interval type sets, determines the main wiring type of the wiring to be processed, including:

[0036] In the A3 and A5 interval type sets, the two buses of the switch intervals that are connected to the incoming and outgoing lines at one end and the busbars at the other two ends are defined as double buses for each other.

[0037] If there are two busbars that are all double busbars, then the main wiring type of the wiring to be processed is determined to be a double busbar wiring.

[0038] If there are three buses that are all double-buses, then the main wiring type of the wiring to be processed is determined to be a double-bus single-segment wiring.

[0039] If there are four busbars that are all double busbars, then the main wiring type of the wiring to be processed is determined to be double busbar double segmented wiring.

[0040] The wiring identification based on the characteristics of various wiring configurations, combined with the various switch interval type sets, determines the main wiring type of the wiring to be processed, including:

[0041] Store all main buses into the BUS-M set;

[0042] In the B1 bay type set, the other end of all switch bays that are connected to the incoming and outgoing lines are identified as bypass buses, and all bypass buses are stored in the BUS-P set.

[0043] If the non-incoming / outgoing line bays in the A1 bay type set, A2 bay type set, A3 bay type set, A4 bay type set, A5 bay type set, and A6 bay type set are connected to the busbars in the BUS-M set and BUS-P set at each end, and the main busbar and bypass busbar are located on both sides of the circuit breaker bay, then the main wiring type of the wiring to be processed is determined to be a bypass wiring.

[0044] Secondly, this application provides a main wiring type identification device based on a bay topology, comprising:

[0045] The module is used to define the structural types and classification principles of switch bays, including 6 types of circuit breaker bays and 2 types of disconnector switch bays.

[0062] This application provides an embodiment of a main wiring type identification method based on a bay topology. It should be noted that although the logical order is shown in the flowchart, under certain data conditions, the steps shown or described may be performed in a different order than that shown here.

[0063] This application uses an electronic device as the execution subject for example, and the main line identification system is used as one of the manifestations of the electronic device, without limitation.

[0064] Reference Figure 1 and Figure 2 , Figure 1 This is a flowchart illustrating the main wiring type identification method based on bay topology provided in this application; Figure 2 This application provides the structural types of switch bays. The main wiring type identification method based on bay topology provided in this application includes:

[0065] Step S10: Determine the structural types and classification principles of switch bays, including 6 types of circuit breaker bays and 2 types of disconnector switch bays;

[0066] Step S20: Classify the switching equipment into the corresponding bay type, and construct the bay topology relationship based on the switching bays and the equipment connected to them;

[0067] Step S30: Based on the interval topology, preprocess the wiring to be processed to obtain a set of switch interval types for the wiring to be processed.

[0068] This application embodiment requires transforming the original power grid topology, which is based on individual primary equipment, into a topology based on bays. Specifically, it involves first dividing the switching bays by using circuit breakers and disconnectors as the core equipment, thus creating circuit breaker bays and disconnector bays. Further, based on the number of terminals and equipment composition within each switching bay, it can be divided into eight different types of switching bays, with the specific steps as follows:

[0069] Switch bays are classified into circuit breaker bays and disconnector bays. Circuit breaker bays are classified as type A, and disconnector bays as type B. The characteristics of a circuit breaker bay are: it consists of a single circuit breaker as its core, containing all disconnectors directly connected to the circuit breaker. The characteristics of a disconnector bay are: it consists of a single disconnector as its core, containing other disconnectors on either side of it.

[0070] Furthermore, based on the location of the disconnecting switches, circuit breaker bays are divided into six categories: A1 (only one circuit breaker); A2 (one circuit breaker with one disconnecting switch on one side); A3 (one circuit breaker with two disconnecting switches on one side); A4 (one circuit breaker with one disconnecting switch on each side); A5 (one circuit breaker with one disconnecting switch on one side and two disconnecting switches on the other side); and A6 (one circuit breaker with two disconnecting switches on each side).

[0071] Furthermore, based on the location of other disconnect switches, the disconnect switch intervals are divided into two categories: one with only one disconnect switch, classified as category B1; and one with one disconnect switch on each side, classified as category B2.

[0072] Furthermore, based on the non-disconnecting core equipment connected to the switch bay, each switch bay is assigned incoming and outgoing line attributes, thereby constructing the bay topology. For example, a switch bay connected to a transformer can be marked as a transformer bay.

[0073] Further, the basic topology data (wiring to be processed) of the target plant is extracted. The wiring to be processed is preprocessed based on the bay topology relationships to obtain preprocessing results, i.e., the main wiring type is analyzed within the scope of the preprocessing results. Then, all switch bays at this location are divided into 8 different switch bay types and stored in the following sets: A1 bay type set, A2 bay type set, A3 bay type set, A4 bay type set, A5 bay type set, A6 bay type set, B1 bay type set, and B2 bay type set. Specifically, the A1 bay type set is defined as the BAYA1 set, the A2 bay type set as the BAYA2 set, the A3 bay type set as the BAYA3 set, the A4 bay type set as the BAYA4 set, the A5 bay type set as the BAYA5 set, the A6 bay type set as the BAYA6 set, the B1 bay type set as the BAYB1 set, and the B2 bay type set as the BAYB2 set.

[0074] Furthermore, analyze the equipment connected to each end of each switch bay and label the equipment attributes of the switch bay: if only one end is connected to the incoming or outgoing line, label it as the incoming / outgoing line type and name; if none of the ends are connected to the incoming or outgoing line, label it as a non-incoming / outgoing line type.

[0075] Step S40: Based on the wiring characteristics of various wirings, and combined with the set of each switch interval type, wiring identification is performed to determine the main wiring type of the wiring to be processed.

[0076] Furthermore, the main wiring types in this application embodiment include, but are not limited to, delta wiring, 3 / 2 or 4 / 3 wiring, bridge wiring, single bus wiring, single bus segmented wiring, double bus wiring, double bus segmented wiring, and wiring with bypass. Therefore, it is necessary to determine the wiring characteristics of delta wiring, 3 / 2 or 4 / 3 wiring, bridge wiring, single bus wiring, single bus segmented wiring, double bus wiring, double bus segmented wiring, and wiring with bypass. Based on the wiring characteristics of delta wiring, 3 / 2 or 4 / 3 wiring, bridge wiring, single bus wiring, single bus segmented wiring, double bus wiring, double bus segmented wiring, and wiring with bypass, wiring identification is performed on each set of switch bay types to determine the main wiring type of the wiring to be processed, as described in steps S401 to S420.

[0077] The main wiring type identification method based on bay topology provided in this application preprocesses the wiring to be processed by constructing the bay topology relationship during the main wiring type identification process. Then, it automatically analyzes and identifies the main wiring type of the wiring by combining the obtained set of various switch bay types with the wiring characteristics of various wirings, thereby improving the accuracy of main wiring type identification and providing accurate static data for substation anti-misoperation rule judgment.

[0078] Furthermore, the main wiring types include, but are not limited to, delta wiring, 3 / 2 or 4 / 3 wiring, bridge wiring, single busbar wiring, single busbar segmented wiring, double busbar wiring, double busbar segmented wiring, and wiring with bypass. The identification process for delta wiring is as follows: (Step S401)

[0079] Step S401: If the characteristics of a delta connection are determined based on the various sets of switch interval types, then the main connection type of the connection to be processed is determined to be a delta connection.

[0080] The characteristics of a delta connection are: Within the A4 bay type set, there exists an independent loop where switch bays are connected end-to-end, and each independent loop contains at least three switch bays; within each independent loop, a switch bay from the B1 bay type set is connected between every two switch bays. In other words, the characteristics of a delta connection are: within the BAYA4 set, there exists an independent loop where switch bays are connected end-to-end (i.e., each switch bay's endpoint is connected to only two bays), and each independent loop contains three or more switch bays; within each independent loop, a switch bay from the BAYB1 set is connected between every two switch bays.

[0081] Therefore, if the independent ring and the switch bays in the connected BAYB1 set satisfy the characteristics of a delta connection, these switch bays form a delta connection, that is, the main connection type of the connection to be processed is a delta connection, and the number of circuit breaker bays contained in the independent ring is the number of corners of the delta connection.

[0082] This application embodiment automatically identifies delta wiring based on its characteristics, improving the accuracy of main wiring type identification and providing accurate static data for substation error prevention rule judgment.

[0083] Furthermore, the identification process for 3 / 2 or 4 / 3 wiring is as follows, specifically in step S402:

[0084] Step S402: If the switch interval type set determines that it conforms to the 3 / 2 or 4 / 3 wiring characteristics, then the main wiring type of the wiring to be processed is determined to be 3 / 2 or 4 / 3 wiring.

[0085] The characteristics of 3 / 2 or 4 / 3 wiring are as follows: there are at least two busbars; the number of strings consisting of all switch bays between the two busbars is at least two, wherein the switch bays are bays from the A4 bay type set, A2 bay type set, A1 bay type set, and B1 bay type set; at least one string between the two busbars has three or four circuit breaker bays; if there are only two strings between the two busbars, then at least one busbar is not connected to a disconnecting switch bay. This can be understood as follows: the characteristics of 3 / 2 or 4 / 3 wiring are: (1) at least two of the busbars at the same location are stored in the BUS set; (2) between two busbars in the BUS set, find all the switch bays that make up the string, and the switch bays are the switch bays in the BAYA1 set, BAYA2 set, BAYA4 set and BAYB1 set; (3) there are at least two strings between the two busbars; (4) among all the strings between the two busbars, at least one string contains 3 or 4 circuit breaker bays; (5) if there are only 2 strings between the two busbars, then at least one busbar is not connected to the isolating switch bay. Characteristic (4) takes into account that some strings are incomplete, but among all strings, there must be one complete string. Characteristic (5) is to distinguish the 3 / 2 wiring with 2 strings from the hexagonal wiring. The busbars of 3 / 2 wiring are generally not directly connected to the circuit, but it is considered that one plant service start-up standby transformer should be allowed to be connected to one busbar. If two plant start-up standby transformers are connected to two different busbars, it can only be determined that it is a delta connection, not a 3 / 2 connection.

[0086] Therefore, if all the strings between two busbars that meet the above-mentioned characteristics of series wiring, as well as the disconnecting switch bays of the connected strings, these switch bays form a 3 / 2 wiring or a 4 / 3 wiring, and these two busbars are marked as main busbars. The maximum number of circuit breaker bays contained in all strings determines the main wiring type: if the maximum number of circuit breaker bays is 3, the main wiring type of the wiring to be processed is 3 / 2 wiring; if the maximum number of circuit breaker bays is 4, the main wiring type of the wiring to be processed is 4 / 3 wiring.

[0087] This application's embodiments automatically identify 3 / 2 and 4 / 3 wiring based on their characteristics, improving the accuracy of main wiring type identification and providing accurate static data for substation error prevention rule judgment.

[0088] The identification process for the bridging wire is as follows, as described in steps S403 to S409:

[0089] Step S403: Determine the switch bays in the A1 bay type set, A2 bay type set, A4 bay type set and B1 bay type set that have one end connected to the incoming and outgoing lines, and store the other end of the switch bay in the NQ set.

[0090] Step S404: Store the common endpoints of all incoming and outgoing line intervals that meet the conditions in the A1 interval type set, the A2 interval type set, and the A4 interval type set into the BUSQ set. The conditions are: the incoming and outgoing line intervals are only connected to one incoming and outgoing line interval in the B1 interval type set, and the incoming and outgoing line names are different.

[0091] Step S405: If one end of a non-incoming / outgoing line interval in the A1 interval type set, the A2 interval type set, and the A4 interval type set is connected to an endpoint in the BUSQ set and the other end is connected to an endpoint in the NQ set, then the two endpoints are determined to be bridge busbars.

[0092] Step S406: If the number of bridge bays of the bridge busbar is one, then the main wiring type of the wiring to be processed is determined to be ordinary bridge wiring.

[0093] Step S407: If the number of bridge bays of the bridge busbar is two and there is a common endpoint, then the main wiring type of the wiring to be processed is determined to be an expanded bridge wiring.

[0094] Step S408: If all main transformer bays in the bridge connection are circuit breaker bays and all line bays are disconnector switch bays, then the main connection type of the connection to be processed is determined to be an external bridge connection.

[0095] Step S409: If all main transformer bays in the bridge connection are disconnector bays and all line bays are circuit breaker bays, then the main connection type of the connection to be processed is determined to be an internal bridge connection.

[0096] Specifically, in sets BAYA1, BAYA2, BAYA4, and BAYB, a switch bay with one end connected to an incoming or outgoing line is searched, and its other end is stored in set NQ. Further, one incoming / outgoing line bay from sets BAYA1, BAYA2, and BAYA4 is selected. If this incoming / outgoing line bay is connected to only one incoming / outgoing line bay in set BAYB, and the incoming / outgoing line names are different, then all common endpoints meeting this condition are stored in set BUSQ. Further, one non-incoming / outgoing line bay from sets BAYA1, BAYA2, and BAYA4 is selected. If one end of this non-incoming / outgoing line bay is connected to an endpoint in set BUSQ, and the other end is connected to an endpoint in set NQ, then this circuit breaker bay is marked as a bridge bay, and both endpoints are marked as bridge buses. All bridge bays are determined according to this condition and stored in set BUSQ-BAY.

[0097] Furthermore, if the BUSQ-BAY set contains only one bridge bay, that bridge bay and its connected incoming and outgoing line bays are ordinary bridge connections, meaning the main wiring type of the wiring to be processed is ordinary bridge connection. If the BUSQ-BAY set contains two bridge bays, and these two bridge bays share a common endpoint, then these two bridge bays and their connected incoming and outgoing line bays are expanded bridge connections, meaning the main wiring type of the wiring to be processed is expanded bridge connection. If, in the bridge connection's switching bays, all main transformer bays are circuit breaker bays and all line bays are disconnector switch bays, then the main wiring type of the wiring to be processed is external bridge connection; if, in the bridge connection's switching bays, all main transformer bays are disconnector switch bays and all line bays are circuit breaker bays, then the main wiring type of the wiring to be processed is internal bridge connection.

[0098] This application embodiment automatically identifies bridge wiring based on its characteristics, improving the accuracy of main wiring type identification and providing accurate static data for substation error prevention rule judgment.

[0099] Furthermore, the identification process for single busbar wiring and single busbar segmented wiring is as follows, as described in steps S410 to S413:

[0100] Step S410: Determine the switch bays in the A1 bay type set, A2 bay type set, and A4 bay type set that have one end connected to the incoming / outgoing line and the other end connected to the bus, and store all the bus in the BUS set;

[0101] Step S411: If the busbar taken out by the BUS set is not connected to the switch bay in the B1 bay type set, then it is determined that all the incoming and outgoing bays of the taken busbar form a single busbar, and the main wiring type of the wiring to be processed is determined to be a single busbar wiring.

[0102] Step S412: After the analysis of all busbars in the BUS set is completed, all single busbar connections are stored in the BUS-Single set, and the non-incoming / outgoing line bays in the A1 bay type set, the A2 bay type set, the A3 bay type set, the A4 bay type set, the A5 bay type set, the A6 bay type set, the B1 bay type set, and the B2 bay type set are determined.

[0103] Step S413: If the two ends of a non-incoming / outgoing line bay or the two ends of a loop composed of two non-incoming / outgoing line bays connected in series are connected to two busbars in a BUS-Single set, and the two busbars are located on both sides of the circuit breaker, then the main wiring type of the wiring to be processed is determined to be a single busbar segmented wiring.

[0104] Specifically, in sets BAYA1, BAYA2, and BAYA4, switch bays with one end connected to an incoming / outgoing line and the other end connected to a busbar are searched, and all such buses are stored in the BUS set. Further, for a bus in the BUS set, if it is not connected to a switch bay in the BAYB set, then all incoming / outgoing line bays connected to this busbar constitute a single busbar, and this busbar is marked as a single-bus main busbar, meaning the main wiring type of the connection to be processed is a single-bus connection. Further, after all buses in the BUS set have been analyzed, all single-bus main buses are stored in the BUS-Single set. Further, search all non-incoming / outgoing line bays in the BAYA1, BAYA2, BAYA3, BAYA4, BAYA5, BAYA6, and BAYB sets. If a non-incoming / outgoing line bay is connected to two busbars in the BUS-Single set at both ends, and these two busbars are located on both sides of a circuit breaker, then the bay is marked as a segmented bay, and the two busbars are marked as mutually segmented. All mutually segmented busbars and connected switch bays constitute a single busbar segmented connection, that is, the main wiring type of the wiring to be processed is a single busbar segmented connection, and the number of busbars is the number of segments. Busbars that are not mutually segmented and connected switch bays constitute a single busbar connection.

[0105] Based on the characteristics of single busbar wiring and single busbar segmented wiring, this application embodiment automatically identifies single busbar wiring and single busbar segmented wiring, improving the accuracy of main wiring type identification and providing accurate static data for substation anti-misoperation rule judgment.

[0106] Furthermore, the identification process for double busbar wiring and double busbar segmented wiring is as follows, as described in steps S414 to S417:

[0107] Step S414: Determine that the two buses of the switch bays in the A3 bay type set and the A5 bay type set, where one end is connected to the incoming and outgoing lines and the other two ends are connected to the busbars, are double buses to each other.

[0108] Step S415: If there are two busbars that are all double busbars, then the main wiring type of the wiring to be processed is determined to be a double busbar wiring.

[0109] Step S416: If there are three buses that are all double-buses, then the main wiring type of the wiring to be processed is determined to be a double-bus single-segment wiring.

[0110] Step S417: If there are four busbars that are all double-busbars, then the main wiring type of the wiring to be processed is determined to be double-busbar double-segment wiring.

[0111] Specifically, in sets BAYA3 and BAYA5, switch bays with one end connected to incoming / outgoing lines and the other two ends connected to busbars are searched. These two busbars are marked as double-bus main busbars and are considered double busbars to each other. All such busbars are stored in the BUS-Double set. Further, non-incoming / outgoing line bays in sets BAYA1, BAYA2, BAYA3, BAYA4, BAYA5, and BAYA6 are searched. If a non-incoming / outgoing line bay is connected to two busbars in the BUS-Double set at both ends, and these two busbars are considered double busbars to each other, and these two busbars are located on both sides of a circuit breaker, then the non-incoming / outgoing line bay is marked as a bus tie bay. Further, search all non-inbound / outbound intervals in all sets BAYA1, BAYA2, BAYA3, BAYA4, BAYA5, BAYA6, and BAYB. If a non-inbound / outbound interval is connected to two buses in the BUS-Double set at both ends, and these two buses are not mutually exclusive, then the non-inbound / outbound interval is marked as a segmented interval.

[0112] Furthermore, if the number of all mutually double-busbar connections is 2, these busbars and connected switch bays constitute a double-busbar connection, meaning the main wiring type of the wiring to be processed is a double-busbar connection. If the number of all mutually double-busbar connections is 3, these busbars and connected switch bays constitute a double-busbar single-section connection, and the main wiring type of the wiring to be processed is a double-busbar connection. If the number of all mutually double-busbar connections is 4, these busbars and connected switch bays constitute a double-busbar double-section connection, and the main wiring type of the wiring to be processed is a double-busbar double-section connection.

[0113] Based on the characteristics of double busbar wiring and double busbar segmented wiring, this application embodiment automatically identifies double busbar wiring and double busbar segmented wiring, improving the accuracy of main wiring type identification and providing accurate static data for substation anti-misoperation rule judgment.

[0114] Furthermore, the identification process for bypass wiring, as described in steps S418 to S420, is as follows:

[0115] Step S418: Store all main buses into the BUS-M set;

[0116] Step S419: In the B1 bay type set, the other end of all switch bays that are connected to the incoming and outgoing lines at one end are determined as bypass buses, and all bypass buses are stored in the BUS-P set.

[0117] Step S420: If the non-incoming / outgoing line bays in the A1 bay type set, A2 bay type set, A3 bay type set, A4 bay type set, A5 bay type set and A6 bay type set are connected to the busbars in the BUS-M set and BUS-P set at each end, and the main busbar and bypass busbar are located on both sides of the circuit breaker bay, then the main wiring type of the wiring to be processed is determined to be a bypass wiring.

[0118] Specifically, bypass wiring is identified based on whether the main wiring type of the wiring to be processed is single busbar wiring, single busbar segmented wiring, double busbar wiring, or double busbar segmented wiring. Therefore, it can be understood that if the current main wiring type is single busbar, single busbar segmented wiring, double busbar wiring, or double busbar segmented wiring, then all main busbars are retrieved and stored in the BUS-M set.

[0119] Further, for each bay in the BAYB set, if one end of the bay is connected to an incoming or outgoing line, its other end is marked as a bypass bus. After analyzing all bays in the BAYB set, all bypass buses are stored in the BUS-P set. Search all non-incoming / outgoing line bays in the BAYA1, BAYA2, BAYA3, BAYA4, BAYA5, and BAYA6 sets. If a non-incoming / outgoing line bay is not included in the current main wiring range, and its ends are only connected to buses in the main bus BUS-M set and the bypass bus BUS-P set, and the main bus and bypass bus are located on opposite sides of the circuit breaker bay, then the bay is marked as a bypass bay. In the current main wiring, adding all switch bays connected by bypass buses that meet the above conditions constitutes a bus and switch bay with bypass wiring; that is, the main wiring type of the wiring to be processed is bypass wiring.

[0120] This application embodiment automatically identifies bypass wiring based on its characteristics, improving the accuracy of main wiring type identification and providing accurate static data for substation error prevention rule judgment.

[0121] In one embodiment, reference is made to Figure 3 , Figure 3 This is a schematic diagram of the 3 / 2 wiring structure provided in this application. In the wiring, the terminal names and device names at both ends of each device are known, and terminals N1 and N2 are labeled as bus terminals. The following section identifies this wiring configuration.

[0122] Preprocessing was performed according to step S30, and the results are shown in Table 1. Table 1 shows the preprocessing results.

[0123] Table 1 Preprocessing results

[0124]

[0125] In the incoming / outgoing line type, "0" indicates a non-incoming / outgoing line type, and "1" indicates an incoming / outgoing line type.

[0126] Based on the characteristics of the angled connection in step S401, no independent loop composed of BAYA4 type intervals was searched, therefore it is not an angled connection;

[0127] According to the serial connection characteristics (1) of the 3 / 2 or 4 / 3 wiring in step S402, the bus endpoints at this location are searched and stored in the BUS set {N1, N2}; according to the serial connection characteristics (2) of the 3 / 2 or 4 / 3 wiring in step S402, the strings between the buses composed of switch bays are searched, and the results are shown in Table 2. Table 2 shows the strings composed of switch bays.

[0128] Table 2. Strings composed of switch intervals

[0129] String number Interval type Interval 1 BAYA4 2

[0130] Furthermore, according to Table 2, there is only one string between bus N1 and bus N2, which does not meet the string connection characteristics (3) of 3 / 2 connection or 4 / 3 connection, so it is not a 3 / 2 connection or 4 / 3 connection.

[0131] Further, the search results for connecting buses obtained according to step S410 are shown in Table 3. Table 3 shows the search results for connecting buses, and the connecting buses are stored in the set BUS{N1}.

[0132] Table 3 Search results for connecting busbars

[0133]

[0134]

[0135] Furthermore, according to step S411, take bus terminal N1 in the BUS set, and the type of switch bay 4 connected to it is B1, so it is not a single bus or a single bus segmented connection.

[0136] Furthermore, no switch bays of type BAYA3 and BAYA5 were found in this wiring, therefore it is not a double bus or double bus segmented wiring;

[0137] Furthermore, as can be seen from steps S418 to S420, the bypass wiring method is based on the existence of a single bus or double bus main line. According to the previous judgment, there is no single bus or double bus main line in this wiring, so it does not belong to the bypass wiring method.

[0138] Further, according to steps S403 to S409, the endpoints that meet the conditions are stored in the NQ set {N1, N2}. According to steps S403 to S409, only the common endpoint N1 of bays 1 and 3 meets the conditions, so it is stored in the BUSQ set {N1}. Further, according to steps S403 to S409, only bay 2 meets the conditions, is marked as a bridge bay, and is stored in the BUSQ-BAY set {2}. The endpoints of this bay are marked as bridge buses, and the set is {N1, N2}. Since there is only one bridge bay in this wiring, according to steps S403 to S409, this wiring is a common bridge wiring. Analysis of Table 1 shows that all main transformer bays are disconnector bays, and all line bays are circuit breaker bays. According to steps S403 to S409, this wiring is an internal bridge wiring.

[0139] Furthermore, the main wiring type identification device based on the interval topology provided in this application will be described below. The main wiring type identification device based on the interval topology and the main wiring type identification method based on the interval topology can be referred to each other.

[0141] Module 401 is used to define the structural types and classification principles of switch bays, including 6 types of circuit breaker bays and 2 types of disconnector switch bays.

[0142] Module 402 is used to classify switchgear into corresponding bay types and construct bay topology relationships based on switch bays and the devices connected to them.

[0143] The preprocessing module 403 is used to preprocess the wiring to be processed based on the interval topology relationship to obtain a set of switch interval types of the wiring to be processed.

[0144] The identification module 404 is used to identify the main wiring type of the wiring to be processed based on the wiring characteristics of various wirings and in combination with the set of various switch interval types.

[0145] Furthermore, module 401 is also used for:

[0146] Switch bays are classified into circuit breaker bays and disconnector bays. Circuit breaker bays are classified as type A, and disconnector bays are classified as type B.

[0147] The circuit breaker bay is characterized by having one circuit breaker as its core and including all disconnecting switches directly connected to the circuit breaker.

[0148] Based on the location of the disconnecting switches, circuit breaker bays are classified into six categories: A1 (only one circuit breaker); A2 (one circuit breaker with one disconnecting switch on one side); A3 (one circuit breaker with two disconnecting switches on one side); A4 (one circuit breaker with one disconnecting switch on each side); A5 (one circuit breaker with one disconnecting switch on one side and two disconnecting switches on the other side); and A6 (one circuit breaker with two disconnecting switches on each side).

[0149] The composition of a disconnector switch bay is characterized by: one disconnector switch as the core, which includes other disconnectors switches on both sides of it;

[0150] Based on the location of other disconnect switches, the disconnect switch bays are divided into two categories: one with only one disconnect switch, classified as category B1; and one with one disconnect switch on each side, classified as category B2.

[0151] Furthermore, the identification module 404 is also used for:

[0152] If the set of switch interval types determines that the characteristics of a delta connection are met, then the main wiring type of the wiring to be processed is determined to be a delta connection.

[0153] The features of the angled connection are as follows: the A4 interval type set contains independent loops with the switch intervals connected end to end, and the independent loop contains at least three switch intervals; in the independent loop, a switch interval from the B1 interval type set is connected between every two switch intervals.

[0154] Furthermore, the identification module 404 is also used for:

[0155] If the switch interval type set determines that it conforms to the 3 / 2 or 4 / 3 wiring characteristics, then the main wiring type of the wiring to be processed is determined to be 3 / 2 or 4 / 3 wiring.

[0156] The 3 / 2 or 4 / 3 wiring characteristics are as follows: there are at least two busbars; the number of strings consisting of all switch bays between the two busbars is at least two, wherein the switch bays are bays from the A4 bay type set, A2 bay type set, A1 bay type set, and B1 bay type set; at least one string among all strings between the two busbars has three or four circuit breaker bays; if there are only two strings between the two busbars, then at least one busbar is not connected to a disconnecting switch bay.

[0157] If the maximum number of circuit breaker bays is 3, then the main wiring type is determined to be 3 / 2 wiring; if the maximum number of circuit breaker bays is 4, then the main wiring type is determined to be 4 / 3 wiring.

[0158] Furthermore, the identification module 404 is also used for:

[0159] Identify the switch bays in the A1, A2, A4, and B1 bay type sets that have one end connected to the incoming and outgoing lines, and store the other end of the switch bay in the NQ set.

[0160] Store the common endpoints of all incoming and outgoing line intervals that meet the conditions in the A1 interval type set, the A2 interval type set, and the A4 interval type set into the BUSQ set. The conditions are: the incoming and outgoing line intervals are only connected to one incoming and outgoing line interval in the B1 interval type set, and the incoming and outgoing line names are different.

[0161] If one end of a non-incoming / outgoing line interval in the A1 interval type set, the A2 interval type set, and the A4 interval type set is connected to an endpoint in the BUSQ set and the other end is connected to an endpoint in the NQ set, then both endpoints are determined to be bridge busbars.

[0162] If the number of bridge bays of the bridge busbar is one, then the main wiring type of the wiring to be processed is determined to be ordinary bridge wiring.

[0163] If the number of bridge bays of the bridge busbar is two, and the two bridge bays have a common endpoint, then the main wiring type of the wiring to be processed is determined to be an expanded bridge wiring.

[0164] If all main transformer bays in the bridge connection are circuit breaker bays and all line bays are disconnector switch bays, then the main connection type of the connection to be processed is determined to be an external bridge connection.

[0165] If all main transformer bays in the bridge connection are disconnector bays and all line bays are circuit breaker bays, then the main connection type of the connection to be processed is determined to be an internal bridge connection.

[0166] Furthermore, the identification module 404 is also used for:

[0167] Identify the switch bays in the A1 bay type set, A2 bay type set, and A4 bay type set that have one end connected to the incoming / outgoing line and the other end connected to the bus, and store all the bus in the BUS set;

[0168] If the busbar taken from the BUS set is not connected to the switch bay in the B1 bay type set, then all the incoming and outgoing bays of the taken busbar are determined to form a single busbar, and the main wiring type of the wiring to be processed is determined to be a single busbar wiring.

[0169] After the analysis of all busbars in the BUS set is completed, all single busbar connections are stored in the BUS-Single set, and the non-incoming / outgoing line bays in the A1 bay type set, the A2 bay type set, the A3 bay type set, the A4 bay type set, the A5 bay type set, the A6 bay type set, the B1 bay type set, and the B2 bay type set are determined.

[0170] If the two ends of a non-incoming / outgoing line bay or the two ends of a loop consisting of two non-incoming / outgoing line bays connected in series are connected to two busbars in a BUS-Single set, and the two busbars are located on both sides of a circuit breaker, then the main wiring type of the wiring to be processed is determined to be a single busbar segmented wiring.

[0171] Furthermore, the identification module 404 is also used for:

[0172] In the A3 and A5 interval type sets, the two buses of the switch intervals that are connected to the incoming and outgoing lines at one end and the busbars at the other two ends are defined as double buses for each other.

[0173] If there are two busbars that are all double busbars, then the main wiring type of the wiring to be processed is determined to be a double busbar wiring.

[0174] If there are three buses that are all double-buses, then the main wiring type of the wiring to be processed is determined to be a double-bus single-segment wiring.

[0175] If there are four busbars that are all double busbars, then the main wiring type of the wiring to be processed is determined to be double busbar double segmented wiring.
