Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method and apparatus for identifying an operating mode of a device. Background Art

[0002] Nowadays, switching operations in a network environment present new control modes, which put forward new requirements for the real-time, intelligent, and reliable performance of the anti-error system. The current trial anti-error rules require the identification of the equipment's operating mode during the judgment and verification process.

[0003] The existing identification method is to first establish an interval template, and then establish an equipment operation mode template for different main connections, different equipment types, different interval types, and different combination states of main connections, equipment and intervals. Finally, the main connection, equipment type, interval type, combination state, etc. of the equipment to be identified are matched one by one with the corresponding items in the equipment operation mode template. If the match is successful, the corresponding equipment operation mode is identified.

[0004] However, under this method, when any new main connection, new equipment type, new interval type or new combination state appears, the original equipment operation mode template is no longer applicable, and a new equipment operation mode template needs to be re-established. In the case of a huge amount of power grid data, the difficulty of data maintenance will be greatly increased, and the real-time nature of equipment operation mode identification cannot be met, thereby affecting the real-time nature and reliability of the anti-error system.

[0067] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0068] Figure 1 This is one of the flow charts of the device operation mode identification method provided in the embodiment of this application. Figure 1 , an embodiment of the present application provides a method for identifying a device operating mode, which may include:

[0069] 101. Combine the circuit breakers and disconnectors in the power grid to obtain a switch interval;

[0070] 102. Determine the operating mode of the device to be identified based on the switch interval connected to the device to be identified.

[0071] In step 101, by combining circuit breakers and disconnectors in the power grid, all types of switch bays can be obtained.

[0072] It should be noted that, since the grounding switch is related to the maintenance status, the grounding switch can also be added to the combination to obtain the switch interval, which can be used to determine whether the operating mode of the equipment to be identified is maintenance.

[0073] In step 102, determining the operating mode of the device to be identified based on the switch interval connected to the device to be identified refers to determining the operating mode of the device to be identified based on the switch interval directly connected to the device to be identified.

[0074] The equipment to be identified may be lines, main transformers, generators, loads, busbars, etc., which are connected by circuit breakers and / or disconnectors.

[0075] The device operation mode identification method provided in this embodiment combines the circuit breakers and disconnectors in the power grid to obtain a switch interval, and determines the operation mode of the device to be identified based on the switch interval connected to the device to be identified. Since the change in the operation mode of the device to be identified is achieved by the opening and closing of the switch device, and the switch device generally includes a circuit breaker and a disconnector, this embodiment combines the circuit breaker and disconnector in the power grid to form a switch interval, which can obtain all types of switch intervals. Since the circuit breaker and disconnector are indispensable general equipment in the power grid and are generally connected to the device to be identified, the operation mode of the device to be identified can be determined based on the switch interval connected to the device to be identified, without considering the difference in main wiring, the difference in the device to be identified, and the difference in combination state. That is, this embodiment can be applied to various situations such as different main wiring, different types of equipment, and different combination states, thereby meeting the real-time nature of device operation mode identification, thereby ensuring the real-time nature and reliability of the anti-error system.

[0083] Figure 9 This is the second wiring diagram of the third switch interval in the device operation mode identification method provided in the embodiment of the present application;

[0084] Reference Figure 2-Figure 9In one embodiment, combining circuit breakers and disconnectors in a power grid to obtain a switch bay may include:

[0085] If the circuit breaker is not connected to any disconnector, identify the circuit breaker as the first switch bay, such as Figure 2 As shown;

[0086] If the circuit breaker is connected to at least one disconnector, the circuit breaker and all disconnectors connected to the circuit breaker are combined to obtain a second switch bay, such as Figure 3-Figure 7 As shown;

[0087] Combining the circuit breaker and all disconnectors connected to the circuit breaker refers to combining the circuit breaker and all disconnectors directly connected to the circuit breaker.

[0088] If there is a single disconnector or three disconnectors connected in series outside the first and second switch bays, the single disconnector is identified as the third switch bay, or the three disconnectors connected in series are combined to obtain the third switch bay, such as Figure 8-Figure 9 shown.

[0089] That is, after all circuit breakers are divided into the first switch bay or the second switch bay, the remaining disconnectors are classified and combined to obtain the third switch bay. Figure 9 ,exist Figure 9 In the diagram, the middle isolating switch indicates the actual isolating switch status, and the isolating switches on both sides are virtual isolating switches, indicating that when the trolley is in the non-operating position, it forms an obvious disconnection point with the equipment on both sides.

[0090] In addition, refer to Figure 2-Figure 9 , where the internal structure of each switch interval can be uniformly regarded as consisting of one core switch, such as Figure 2 and Figure 8 As shown; or it consists of a core switch and isolation switches on both sides of the core switch, such as Figure 3-Figure 7 as well as Figure 9 As shown; the core switch can be named V0, and the isolating switches on both sides can be named V1 to V4 according to their positions. At the same time, each switch interval can be regarded as a whole. The endpoints of the switch interval are the endpoints of the external connections on both sides, which can be numbered 1-4 according to their positions. Figure 2 The switching bay is marked as Class A, i.e. the first switching bay, Figure 3-Figure 7 The switch bays are marked as B1-B5, i.e. the second switch bay, Figure 8-Figure 9 The switching intervals are marked as category C1-C2, i.e. the third switching interval.

[0091] This embodiment divides all combination types of circuit breakers and disconnectors in the power grid into three switch intervals based on the different connection conditions of the circuit breakers and disconnectors. This enables the type identification of the switch interval connected to the device to be identified in the power grid, thereby determining the operating mode of the device to be identified based on the corresponding type of switch interval.

[0092] Figure 10 This is the second flow chart of the device operation mode identification method provided in the embodiment of the present application. Figure 10 In one embodiment, determining the operating mode of the device to be identified based on the switch interval connected to the device to be identified may include:

[0093] 1001. Determine the operating mode of the switch bay according to the open / close status of the circuit breaker and / or disconnector in the switch bay;

[0094] 1002. Determine the operating mode of any endpoint of the device to be identified based on the operating mode of the switch bay connected to the endpoint;

[0095] 1003. Determine the operating mode of the device to be identified based on the operating modes of all endpoints of the device to be identified.

[0096] In steps 1001 to 1003, since the operating mode of each switch interval is determined based on the opening and closing status of the circuit breakers and / or disconnectors in the switch interval, the purpose of updating the switch interval operating mode can be achieved by updating a few circuit breakers and / or disconnectors in the switch interval. Furthermore, by updating the operating mode of a few switch intervals, the purpose of quickly identifying the operating mode of the equipment to be identified in the entire network before and after the update can be achieved. The analysis of the operating mode of the equipment to be identified before and after the update of all switch intervals can be completed before all anti-error rules are checked.

[0097] Devices to be identified can be divided into the following categories based on the number of external connection endpoints:

[0098] 1. Single-ended devices to be identified include generators, loads, and busbars, which have only one end connected to the grid.

[0099] 2. Multi-terminal devices to be identified, including lines and transformers. A normal line connects two power plants at different locations and has two terminals. A T-type line in a distribution network connects three power plants and has three terminals. A π-type line connects four power plants and has four terminals. Transformers connect different voltage levels; a line connecting two voltage levels has two terminals, while a line connecting three voltage levels has three terminals.

[0100] The device to be identified has one or more endpoints, each of which is connected to one or more switch bays. Therefore, the device connection model in the power grid can be described as: device to be identified-endpoint-switch bay.

[0101] This embodiment analyzes the operating mode layer by layer in the order from the switch interval to a certain end of the device to be identified to the entire device to be identified, and forms a general device operating mode description. It can use the switch interval as the minimum judgment unit, judge layer by layer, and then determine the operating mode of the device to be identified.

[0102] Reference Figure 2 In one embodiment, determining the operating mode of a switch bay according to the opening and closing states of a circuit breaker and / or a disconnector in the switch bay may include:

[0103] If the circuit breaker in the first switch bay is in the closed state, determining that the operation mode of the first switch bay is operation;

[0104] If the circuit breaker in the first switch bay is in the open state, it is determined that the operation mode of the first switch bay is hot standby.

[0105] The details can be shown in the following table, among which, Figure 2 In the figure, V0=1 indicates that the circuit breaker is in the closed state, and V0=0 indicates that the circuit breaker is in the open state:

[0108] This embodiment can determine the operation mode of the first switch bay according to the opening and closing states of the circuit breakers in the first switch bay.

[0109] Figure 11 This is the third flow chart of the device operation mode identification method provided in the embodiment of the present application; Figure 3-Figure 7 ,as well as Figure 11 In one embodiment, determining the operating mode of a switch bay according to the opening and closing states of a circuit breaker and / or a disconnector in the switch bay may include:

[0110] 1101. Taking a circuit between a first endpoint and a second endpoint of a second switch interval as a circuit to be identified, and determining an operation mode of the circuit to be identified;

[0111] The first endpoint is an endpoint of the second switch interval close to the device to be identified, and the second endpoint is an endpoint of the second switch interval away from the device to be identified;

[0112] 1102. Setting an operating value of the circuit to be identified according to the operating mode of the circuit to be identified;

[0113] The operating value of the circuit to be identified whose operating mode is operation is a first operating value, the operating value of the circuit to be identified whose operating mode is hot standby is a second operating value, and the operating value of the circuit to be identified whose operating mode is cold standby is a third operating value, and the first operating value is greater than the second operating value, and the second operating value is greater than the third operating value;

[0114] 1103. Compare the operating values ​​of all circuits to be identified in the second switching interval, and determine the operating mode of the circuit to be identified corresponding to the maximum operating value as the operating mode of the second switching interval.

[0115] In step 1101, since the switch interval is close to the endpoint on the side of the device to be identified, that is, usually only one endpoint in the first endpoint is connected to the power grid, and the switch interval is far from the endpoint on the side of the device to be identified, that is, all endpoints in the second endpoint can be connected to the power grid, therefore, Figure 3-Figure 7 It can be seen that the number of circuits to be identified in each second switching interval is different, for example, Figure 3 The second switching interval has only one circuit to be identified between terminal 1 and terminal 3; Figure 4 In the second switching interval, if endpoint 1 and endpoint 2 are the first endpoints and endpoint 3 is the second endpoint, then Figure 4 The second switching interval has a circuit to be identified between endpoints 1 and 3, or a circuit to be identified between endpoints 2 and 3. If endpoint 3 is the first endpoint and endpoints 1 and 2 are the second endpoints, then Figure 4 The second switch interval has two circuits to be identified, one between terminal 1 and terminal 3 and one between terminal 2 and terminal 3; Figure 7 In the second switching interval, if endpoint 1 and endpoint 2 are the first endpoints, and endpoint 3 and endpoint 4 are the second endpoints, then Figure 7 The second switching interval has two circuits to be identified, between endpoints 1 and 3 and between endpoints 1 and 4, or two circuits to be identified, between endpoints 2 and 3 and between endpoints 2 and 4. If endpoints 3 and 4 are the first endpoints and endpoints 1 and 2 are the second endpoints, then Figure 7 The second switch interval has two circuits to be identified, between terminal 1 and terminal 3 and between terminal 2 and terminal 3, or two circuits to be identified, between terminal 1 and terminal 4 and between terminal 2 and terminal 4.

[0116] In step 1103, for example, comparison Figure 4 In the example, endpoint 3 is the first endpoint, endpoints 1 and 2 are the second endpoints, and the operating mode of the circuit to be identified corresponding to the maximum operating value is determined as Figure 4 The second switching interval in the operation mode, or compare Figure 7In any of the above cases, the operating values ​​of the two circuits to be identified are used to determine the operating mode of the circuit to be identified corresponding to the maximum operating value. Figure 7 The second switching interval in the operation mode.

[0117] This embodiment can determine the operating mode of the second switching interval according to the maximum operating value of the circuit to be identified in the second switching interval.

[0118] Reference Figure 3-Figure 7 In one embodiment, determining the operating mode of the circuit to be identified may include:

[0119] If the circuit breaker and the isolating switch in the circuit to be identified are both in the closed state, then the operation mode of the circuit to be identified is determined to be running;

[0120] If the circuit breaker in the circuit to be identified is in the open state and the isolating switch is in the closed state, then the operation mode of the circuit to be identified is determined to be hot standby;

[0121] If at least one isolating switch in the circuit to be identified is in the disconnected state, it is determined that the operation mode of the circuit to be identified is cold standby.

[0122] The details can be shown in the following table, among which, Figure 3-Figure 7 In the figure, V0=1 indicates that the circuit breaker is in the closed state, V0=0 indicates that the circuit breaker is in the open state, V1=1, V2=1, V3=1, and V4=1 indicate that the disconnector V1, disconnector V2, disconnector V3, and disconnector V4 are in the closed state, respectively; V1=0, V2=0, V3=1=0, and V4=0 indicate that the disconnector V1, disconnector V2, disconnector V3, and disconnector V4 are in the open state, respectively:

Figure 2-Figure 9 Figure 12 In one embodiment, the operation mode of any endpoint can be determined according to the operation mode of the switching interval connected with the endpoint, which can include:

[0135] 1201, setting the operation value of the switching interval according to the operation mode of the switching interval;

[0136] wherein the operation value of the switching interval in the operation mode is the first operation value, the operation value of the switching interval in the hot standby mode is the second operation value, the operation value of the switching interval in the cold standby mode is the third operation value, and the first operation value is greater than the second operation value, and the second operation value is greater than the third operation value;

[0137] 1202, if the switching interval connected with any endpoint of the device to be identified does not contain the third switching interval, comparing the operation value of all switching intervals connected with the endpoint and the operation value corresponding to the current operation mode of the endpoint, and determining the operation mode of the switching interval corresponding to the maximum operation value as the operation mode of the endpoint;

[0138] 1203, if the switching interval connected with any endpoint of the device to be identified contains the third switching interval, and the operation mode of the third switching interval is operation, comparing the operation value of all switching intervals connected with the endpoint except the third switching interval, and determining the operation mode of the switching interval corresponding to the maximum operation value as the first tentative operation mode of the endpoint;

[0139] 1204, determining the third switching interval as the switching interval to be processed;

[0140] ​​1205. Search for the next switch interval along the circuit on the side of the switch interval to be processed that is away from the device to be identified;

[0141] 1206. If the next switching interval is the third switching interval and the operation mode of the next switching interval is running, the next switching interval is determined as the switching interval to be processed, and the process returns to step 1205.

[0142] 1207. If the next switching interval is the third switching interval and the operation mode of the next switching interval is cold standby, the operation mode of the next switching interval is determined to be the second pending operation mode of the endpoint;

[0143] 1208. If the next switching interval is not the third switching interval, the operation mode of the next switching interval is determined to be the second pending operation mode of the endpoint;

[0144] 1209. Compare the operating value corresponding to the first pending operating mode, the operating value corresponding to the second pending operating mode, and the operating value corresponding to the current operating mode of the endpoint, and determine the operating mode corresponding to the maximum operating value as the operating mode of the endpoint;

[0145] 1210. If the switch interval connected to any endpoint of the device to be identified includes a third switch interval, and the operating mode of the third switch interval is cold standby, then compare the operating values ​​of all switch intervals connected to the endpoint and the operating values ​​corresponding to the current operating mode of the endpoint, and determine the operating mode of the switch interval corresponding to the maximum operating value as the operating mode of the endpoint.

[0146] In steps 1203 to 1209, since the third switch bay only includes isolating switches, when the operating mode of the third switch bay is operation, that is, when all the isolating switches therein are in the closed state, it is indicated that the circuit in which the third switch bay is located is in the closed state. Thus, the next switch bay can be searched along the circuit in which the third switch bay is located until the first switch bay or the second switch bay or the third switch bay in the cold standby operating mode is found.

[0147] It should be noted that if the next switch interval is another device to be identified, the search is stopped.

[0148] In step 1210, since the third switch interval only includes isolating switches, when the operation mode of the third switch interval is cold standby, that is, when at least one isolating switch is in the disconnected state, it indicates that the circuit where the third switch interval is located is disconnected, and there is no need to search for the next switch interval along the circuit where the third switch interval is located.

[0149] It should be noted that the initial operation mode of all endpoints of the device to be identified can be set to cold standby.

[0150] This embodiment divides the different modes of determining the operation mode of the endpoint by the different types of switch intervals connected to the endpoint of the device to be identified, and can specifically determine the operation mode of the endpoint when it is connected to different types of switch intervals, making the determination of the endpoint operation mode more accurate.

[0151] Figure 13 This is the fifth flow chart of the device operation mode identification method provided in the embodiment of the present application; Figure 13 In one embodiment, determining the operating mode of the device to be identified based on the operating modes of all endpoints of the device to be identified includes:

[0152] 1301. Setting the operation value of any endpoint of the device to be identified according to the operation mode of the endpoint;

[0153] The operating value of the endpoint in operation mode is a first operating value, the operating value of the endpoint in hot standby mode is a second operating value, and the operating value of the endpoint in cold standby mode is a third operating value, and the first operating value is greater than the second operating value, and the second operating value is greater than the third operating value;

[0154] 1302. Compare the operating values ​​of all endpoints of the device to be identified, and determine the operating mode of the endpoint corresponding to the maximum operating value as the operating mode of the device to be identified.

[0155] This embodiment can determine the operating mode of the device to be identified by the maximum value of the operating values ​​of all endpoints of the device to be identified.

[0156] Figure 14 This is a wiring diagram of a device to be identified in the device operation mode identification method provided in the embodiment of the present application; Figure 14 In one embodiment, Figure 14 The circuit breaker symbol in the figure is hollow when it is in the open state and solid when it is in the closed state. The initial operation mode of endpoints 2 and 4 of line L is cold standby. The method for identifying the operation mode of line L at the next moment after the initial moment is as follows:

[0157] 1. Determine the switch bays connected to line L as Bay 1 to Bay 4. The operation modes of these switch bays and the circuits to be identified therein are shown in the following table:

[0158] Table 4 Operation mode table 1 (with Figure 14 For example)

[0159]

[0160] 2. Endpoint 2 of line L is connected to switch bays Bay 1 and Bay 2. Bay 1 is in operation mode, Bay 2 is in hot standby mode, and the current operation mode of endpoint 2 is the initial operation mode, namely, cold standby. If the operation value of Bay 1 > the operation value of Bay 2 > the operation value corresponding to the current operation mode of endpoint 2, then the operation mode of endpoint 2 of line L is operation.

[0161] At the same time, since the terminal 4 of line L is connected to the switch bays Bay3 and Bay4, where the operation mode of Bay3 is operation and the operation modes of the two circuits to be identified in Bay4 are both cold standby, the operation mode of Bay4 is cold standby.

[0162] However, since Bay 3 is the third switching bay, the first pending operating mode of endpoint 4 is determined to be the operating mode of Bay 4, i.e., cold standby. The next switching bay is searched along the circuit on the side of Bay 3 away from line L. The search results lead to Bay 5. The operating mode of the circuit to be identified in Bay 5 is shown in the following table:

[0163] Table 5 Operation mode table 2 (with Figure 14 For example)

[0164]

[0165] Since the operating modes of the two circuits to be identified in Bay 5 are operation and cold standby, respectively, the operating mode of Bay 5 is operation. That is, the second pending operating mode of endpoint 4 is the operating mode of Bay 5, namely operation. The operating value of Bay 5 is greater than the operating value of Bay 4, which is equal to the operating value corresponding to the current operating mode of endpoint 4. Therefore, the operating mode of endpoint 4 of line L is operation.

[0166] 3. Since the operating modes of endpoints 2 and 4 of line L are both run, the operating mode of line L is run.

[0167] Figure 15 This is a wiring diagram of the device operation mode identification method provided in the embodiment of the present application, with the main transformer as the device to be identified; Figure 15 In one embodiment, Figure 15 The circuit breaker symbol in the figure is hollow, indicating that the circuit breaker is in the open state, and solid, indicating that the circuit breaker is in the closed state. The initial operating modes of terminals 4, 5, and 7 of the main transformer T are all cold standby. The method for identifying the operating mode of the main transformer T at the next moment after the initial moment is as follows:

[0168] 1. Determine the switch bays connected to the main transformer T as Bay 1 to Bay 3. The operation of these switch bays is shown in the following table:

[0169] Table 6 Operation mode table 3 (with Figure 15 For example)

[0170]

[0171] 2. Since the switching bay Bay 1 connected to the terminal 4 of the main transformer T is the third switching bay, and the operation mode of Bay 1 is operation, the next switching bay is searched along the circuit on the side of Bay 1 away from the main transformer T. Bay 4 and Bay 5 are found. The operation modes of Bay 4 and Bay 5 are shown in the following table:

[0172] Table 7 Operation mode table 4 (with Figure 15 For example)

[0173]

[0174] The operating value of Bay5>the operating value of Bay4=the operating value corresponding to the current operating mode of terminal 4. Therefore, the operating mode of terminal 4 of the main transformer T is operation.

[0175] Since the operating mode of the switch bay Bay2 connected to the terminal 5 of the main transformer T is operation, and the operating value of Bay2 is greater than the operating value corresponding to the current operating mode of the terminal 5, the operating mode of the terminal 5 of the main transformer T is operation.

[0176] Since the switch bay Bay3 connected to the terminal 7 of the main transformer T is the third switch bay and the operating mode of Bay3 is cold standby, the operating value of Bay3 equals the operating value corresponding to the current operating mode of terminal 7. Therefore, the operating mode of terminal 7 of the main transformer T is cold standby.

[0177] 3. The operation mode of terminal 4 of the main transformer T is operation, the operation mode of terminal 5 is operation, and the operation mode of terminal 7 is cold standby. Then the operation mode of the main transformer T is operation.

[0178] Figure 16 This is a wiring diagram of the busbar as the device to be identified in the device operation mode identification method provided in the embodiment of the present application; Figure 16 In one embodiment, Figure 16 The circuit breaker symbol in the diagram is hollow when it is in the open state, and solid when it is in the closed state. The initial operation mode of both endpoint 3 of bus 1 and endpoint 4 of bus 2 is cold standby. The method for identifying the operation mode of bus 1 at the next moment after the initial moment is as follows:

[0179] 1. Determine that the switch bays connected to bus Bus1 are Bay1 to Bay3. The operating modes of the switch bays connected to bus Bus1 and the circuits to be identified connected to bus Bus1 are shown in the following table:

[0180] Table 8 Operation Mode Table 5 (with Figure 16 For example)

[0181]

[0182]

[0183] 2. Compare the operating values ​​corresponding to the operating modes in the above table with the operating values ​​corresponding to the current operating mode of endpoint 3. If the operating mode corresponding to the maximum operating value is Run, the operating mode of endpoint 3 of bus Bus1 is Run.

[0184] 3. Since Bus1 is a single-ended device to be identified, the operation mode of Bus1 is the same as the operation mode of endpoint 3, that is, operation.

[0185] Similarly, if the operating mode of bus Bus2 is running, then the operating mode of the entire bus (including bus Bus1 and bus Bus2) is also running.

The device operating mode identification apparatus described below and the device operating mode identification method described above can be referenced to each other.
