Description

Technical Field

[0001] The present application relates to the field of direct current transmission, and in particular to a method, apparatus, computer equipment, storage medium and computer program product for identifying a type of a direct current switch. Background Art

[0002] The DC system is an important part of DC power transmission. There are many types of DC main equipment in the DC system, including converters, DC lines, DC switches, DC grounding electrodes, and filters. There are multiple DC switches in the DC system. The operation mode of the DC system can be adjusted by setting the on and off states of these switches. In order to adjust the operation mode of the DC system, it is necessary to first identify the switch type of each DC switch. Usually, the switch type of the DC switch is identified manually, but with the increase in the number of DC systems and when the DC system wiring method changes, the switch type needs to be manually maintained, which makes the maintenance workload larger and prone to errors. Therefore, the method of manually identifying the switch type becomes infeasible.

[0003] The current working method of manually identifying DC switch types cannot adapt to the situation where there are a large number of DC systems and the maintenance workload increases after the wiring method changes. In addition, during the manual identification process, there is a problem of incorrect switch type setting due to errors or untimely manual maintenance after the wiring method changes. Therefore, the working method of manually identifying DC switch types is low in efficiency and accuracy. Summary of the invention

[0099] The computer device may be a terminal.

[0100] In one embodiment, Figure 1 As shown, a method for identifying a DC switch type is provided, the method is applied to a computer device, and comprises the following steps:

[0101] Step 102, searching a device-related table of the target DC system, obtaining a switch that shares a connection point with the filter, and determining that the type of the switch is a filter switch.

[0102] The DC system is an important component of DC power transmission. The DC system contains various types of DC equipment and multiple DC switches. The operation mode of the DC system can be adjusted by setting the switch on and off state. Figure 2As shown in the figure, by analyzing the topology diagram, it can be found that in the DC system, some DC switches are connected to DC main devices such as converters, DC poles, DC lines, DC grounding poles, filters, and some DC switches are connected to other DC switches. Therefore, the switch type of the DC switch connected to the DC main device can be identified through the topological connection relationship, and then the switch type of other DC switches can be identified through the topological connection relationship. In this way, the switch type of each DC switch can be identified through the wiring method of the DC system.

[0103] Based on this concept, by analyzing the topology diagram, manually processing the relevant information table and endpoint table of each device, the relevant information table of the device records the name of the device and the endpoint of the device, and the endpoint table records the mapping relationship between the endpoint and the connection point. By searching for the common endpoint through these tables, the connection relationship between the devices can be analyzed, and then the switch type can be identified. For example, Figure 2 As shown, the switch directly connected to the two ends of the filter in the DC pole is the DC pole filter switch.

[0104] The device-related table records the name and endpoint information of each DC main device, and the endpoint table records the mapping relationship between the endpoint and the corresponding connection point. Based on this, the filter table, switch table and endpoint table can be searched to determine that the switch that shares the connection point with the filter is the filter switch.

[0105] Step 104, searching a device-related table of the target DC system, obtaining a switch that shares a connection point with the converter and the filter, and determining that the type of the switch is a DC pole-end switch.

[0106] Specifically, Figure 2 As shown, the switch connected to both the converter head end and the filter switch is the DC pole head end switch. Based on this basis, the converter table, filter table, switch table and endpoint table can be searched to determine that the switch that shares the connection point with both the converter head end and the filter is the DC pole head end switch. The switch connected to both the converter end and the filter switch is the DC pole head end switch. Based on this basis, the converter table, filter table, switch table and endpoint table can be searched to determine that the switch that shares the connection point with both the converter end and the filter is the DC pole head end switch.

[0107] The head end of the converter is the end far away from the DC grounding electrode, and the tail end of the converter is the end close to the DC grounding electrode.

[0108] Step 106, searching a device-related table of the target DC system, obtaining a switch that shares a connection point with the DC grounding electrode, and determining that the type of the switch is a DC grounding switch.

[0109] Specifically, Figure 2As shown, the switch directly connected to the DC grounding electrode is the DC grounding switch. Based on this basis, the DC grounding electrode table, switch table and terminal table can be searched to determine that the switch that shares the connection point with the DC grounding electrode is the DC grounding switch.

[0110] Step 108, searching the device-related table of the target DC system, obtaining a switch that shares a connection point with the DC pole head and end switch and the DC ground switch, and determining that the type of the switch is a DC pole loop switch.

[0111] Specifically, Figure 2 As shown, a switch with one end connected to the DC pole end switch and the other end connected to the DC ground switch is a DC large loop switch. Based on this, the DC pole end switch table, DC ground switch table, switch table and endpoint table can be searched to determine that a switch with one end sharing a connection point with the DC pole end switch and the other end sharing a connection point with the DC ground switch is a DC large loop switch.

[0112] Step 110, searching the device-related table of the target DC system, obtaining the switch with the common connection point of the two DC lines, and determining the switch on the shortest path among the paths of the common connection point of the two DC lines as the metal line DC pole switch.

[0113] Specifically, Figure 2 As shown, the switch on the shortest path between the two DC lines is a metal line DC pole switch. Based on this, the DC line table, switch table and endpoint table can be searched to determine that the switch on the shortest path with the common connection point of the DC line is a metal line DC pole switch.

[0114] Step 112, searching a device-related table of the target DC system, obtaining a switch that shares a connection point with the DC line and the metal wire DC pole switch, and determining that the type of the switch is a DC line switch.

[0115] Specifically, Figure 2 As shown, the switch connected to both the DC line and the metal wire DC pole switch is the DC line switch. Based on this, the DC line table, the metal wire DC pole switch table, the switch table and the endpoint table can be searched to determine that the switch that shares the connection point with both the DC line and the metal wire DC pole switch is the DC line switch.

[0116] Step 114, searching the device-related table of the target DC system, obtaining a switch that shares a connection point with the two metal line DC pole switches, and determining that the type of the switch is a DC metal return line switch.

[0117] Specifically, Figure 2As shown, the switch connected to both the first metal wire DC pole switch and the second metal wire DC pole switch is a DC metal return switch. Based on this, the first metal wire DC pole switch, the second metal wire DC pole switch, the switch table and the endpoint table can be searched to determine that the switch sharing the connection point with the first metal wire DC pole switch and the second metal wire DC pole switch is a DC metal return switch.

[0118] Step 116, searching a device-related table of the target DC system, obtaining a switch that shares a connection point with the first side of the DC metallic return switch, and determining that the type of the switch is a DC pole metallic return switch.

[0119] Specifically, Figure 2 As shown, the switch directly connected to the left side of the DC metal loop switch is the DC pole metal loop switch. Based on this, the DC metal loop switch table, switch table and terminal table can be searched to determine that the switch on the left side of the shared connection point with the DC metal loop switch is the filter switch.

[0120] In this embodiment, the device-related table of the target DC system is searched to obtain a switch that shares a connection point with the filter, and determine that the type of the switch is a filter switch. Further, the switch that shares a connection point with the converter and the filter is obtained, and the type of the switch is determined to be a DC pole head and end switch. Further, the switch that shares a connection point with the DC grounding pole is obtained, and the type of the switch is determined to be a DC ground switch. Further, the switch that shares a connection point with the DC pole head and end switch and the DC ground switch is obtained, and the type of the switch is determined to be a DC large loop switch. Further, the switch that shares a connection point with two DC lines is obtained, and the switch on the shortest path is a metal wire DC pole switch. Further, the switch that shares a connection point with the DC line and the metal wire DC pole switch is obtained, and the type of the switch is determined to be a DC line switch. Further, the switch that shares a connection point with two metal wire DC pole switches is obtained, and the type of the switch is determined to be a DC metal loop switch. Further, the switch that shares a connection point with the left side of the DC metal loop switch is obtained, and the type of the switch is determined to be a DC pole metal loop switch. This method determines the common connection points of the devices by looking up a table, and the common connection points can reflect the connection relationship of the devices in the topological connection relationship.
