[0058] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and more detailed descriptions will be provided hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0059] Here, exemplary embodiments will be described in detail, and examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0060] With the increase in people's demand for electricity, line overloading often occurs during peak electricity consumption periods or under special operating modes. For example, overloads of main transformers or lines of main equipment in regional power grids are caused by faults, and it is necessary to quickly eliminate or limit the overload of the main equipment. Therefore, it is necessary to determine whether there is overloading on the line to facilitate timely handling of problems on the line.

[0061] However, there are various types of switches on the line, and it is difficult to determine the status of different types of switches through a unified overloading judgment method. Especially for non-automatic ordinary switches, the real-time current of ordinary switches cannot be directly collected, which causes difficulties in judging overloading.

[0062] A method, device, electronic device, and storage medium for determining a line state provided by the present application are intended to solve the above-mentioned technical problems in the prior art.

[0063] The following uses specific embodiments to detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0064] Figure 1 A flowchart of a method for determining a line state provided by an embodiment of the present application. This method can be executed by a device for determining a line state, and multiple switches are configured on the line. As Figure 1 shown, this method includes:

[0065] S101. Determine the switch type of the switch to be confirmed.

[0066] Exemplarily, different types of switches can be deployed on the line. For example, the switch types can include automated switches and non-automated switches, etc. That is, the switch type of the switch to be confirmed can be an automated switch or a non-automated switch. In this embodiment, the switch to be confirmed can be a loop-opening point switch, that is, it can be determined whether the loop-opening point switch is an automated switch or a non-automated switch.

[0067] When constructing the line, the switch types of each switch on the line can be determined in advance. That is, when determining whether the line is overloaded or overloaded based on the switch to be confirmed, the switch type of the switch to be confirmed can be directly found.

[0068] Automated switches can also be called three-remote switches, and non-automated switches can be non-three-remote switches. Three-remote switches can not only perform remote control operations, but also perform remote measurement and remote protection of electrical equipment, etc. Non-three-remote switches, such as two-remote switches, usually can only perform the most basic remote control operations, and they represent different fault information through binary codes. For automated switches, real-time current values and other information can be directly obtained. For non-automated switches, real-time current values and other information cannot be directly collected.

[0069] S102. Determine the target switch from the line according to the switch type of the switch to be confirmed.

[0070] Exemplarily, after determining the switch type of the switch to be confirmed, the target switch corresponding to the switch to be confirmed can be determined according to different switch types. The target switch is also on the line, and may be the switch to be confirmed itself, or other switches other than the switch to be confirmed. For example, the automated switch adjacent to the switch to be confirmed can be determined as the target switch, so that the real-time current value of the target switch can be directly obtained regardless of the switch type of the switch to be confirmed.

[0071] In this embodiment, determining the target switch from the line according to the switch type of the switch to be confirmed includes: if the switch type of the switch to be confirmed is an automated switch, then determine that the target switch on the line is the switch to be confirmed.

[0072] Specifically, if it is determined that the switch type of the switch to be confirmed is an automated switch, it means that various current parameters and other relevant information of the switch to be confirmed can be directly obtained, and the switch to be confirmed is the target switch.

[0073] The beneficial effect of this setting is that for switches of the automated type, the target switch is the switch to be confirmed itself, and there is no need to rely on other switches to determine the status information, which improves the determination accuracy of the status of the switch to be confirmed.

[0074] In this embodiment, determining a target switch from a line according to the switch type of the switch to be confirmed includes: if the switch type of the switch to be confirmed is a non-automated switch, determining the upstream switch of the switch to be confirmed from the line; where the upstream switch represents the first automated switch adjacent to the switch to be confirmed and located upstream of the switch to be confirmed on the line; and determining the upstream switch as the target switch.

[0075] Specifically, if it is determined that the switch type of the switch to be confirmed is a non-automated switch, it means that various current parameters and other relevant information of the switch to be confirmed cannot be directly obtained, and it is necessary to use other switches to judge the status information of the line, and the other switches used should be automated switches. For example, the upstream switch of the switch to be confirmed can be determined from the line, and the upstream switch is determined as the target switch. The upstream switch is the first automated switch on the line located upstream of the switch to be confirmed, and the upstream direction is the direction extending towards the in-station switch on the side of the switch to be confirmed, that is, the first automated switch extending towards the in-station switch on this side is determined as the target switch.

[0076] The nearest automated switch to the switch to be confirmed can be found from the line as the target switch corresponding to the switch to be confirmed. Figure 2 It is a schematic diagram of the switch layout on the line. The in-station switches are automated switches, and the in-station switch A and the in-station switch G are the in-station switches of the opposite-side lines to each other. The tie switch E is in the off state and the current is 0. The distribution transformer is a power distribution transformer. If the switch to be confirmed is the automated switch C, then the automated switch C is the target switch; if the switch to be confirmed is the non-automated switch B, then the switches on the same side as the non-automated switch B are determined, including the in-station switch A, the automated switch C, and the non-automated switch D. Among them, the automated switch located upstream of the non-automated switch B and adjacent to the non-automated switch B is the in-station switch A, that is, the target switch is the in-station switch A.

[0077] The beneficial effect of such a setting is that for non-automated switches, the target switch is the first automated switch upstream of the switch to be confirmed. By using the first adjacent automated switch as the target switch, the judgment error of the status information can be reduced, and the status determination of non-automated switches can be realized, improving the determination accuracy and efficiency of the status information.

[0078] S103. Obtain the current information of the target switch and the current information of the in-station switch on the opposite side of the switch to be confirmed; where the in-station switch on the opposite side represents the in-station switch of the opposite-side line of the switch to be confirmed.

[0079] Exemplarily, the in-station switch on the opposite side of the switch to be confirmed is determined from the line, and the in-station switch on the opposite side refers to the in-station switch on the opposite-side line of the switch to be confirmed. As Figure 2 shown, if the switch to be confirmed is the non-automated switch B, then the in-station switch on the opposite side is the in-station switch G.

[0080] The in-station switch is an automated switch. Therefore, the current information of the switch on the opposite side of the station can be directly obtained. The target switch is also an automated switch. Therefore, the current information of the target switch can also be directly obtained. The current information can be information such as the electrical parameters of the switch. For example, it can include current, voltage, power, etc.

[0081] S104. Determine the line status information according to the current information of the target switch and the current information of the switch on the opposite side of the station; wherein, the status information characterizes whether the line is overloaded or overloaded after power transfer.

[0082] Exemplarily, according to the current information of the target switch and the current information of the switch on the opposite side of the station, it can be determined whether the line is overloaded or overloaded after power transfer. If so, an alarm message can be sent to the staff; if not, monitoring can continue. The alarm message can include the identification of the switch to be confirmed and the determined status information, etc.

[0083] The determination conditions of the status information can be preset. Determine whether the current information of the target switch and the current information of the switch on the opposite side of the station meet the preset conditions. If so, it is determined that the line is overloaded; if not, it is determined that the line is not overloaded. In this embodiment, the preset determination conditions are not specifically limited. For example, the current value can be obtained from the current information, and the preset determination condition can be to determine whether the current values of the target switch and the switch on the opposite side of the station both meet the preset numerical magnitudes.

[0084] The current limit value of the switch on the opposite side of the line in the station is the limit value of the line diameter current-carrying capacity of the line, which is used to judge whether the line is overloaded. In this embodiment, generally, the line diameter current-carrying capacity of the line connecting the in-station switch is used as the limit value. This limit value can be queried at the position of the switch to be confirmed, and the current flowing through the switch on the opposite side of the station after power transfer is compared with this limit value to determine the status information.

[0085] The method for determining the line status provided in the embodiment of the present application can determine a target switch on the line for different types of switches by determining the switch type of the switch to be confirmed. For different switch types, different target switches can be determined. When judging whether it is overloaded, the current information of the target switch and the current information of the switch on the opposite side of the station to be confirmed can be obtained, and then according to the current information of the target switch and the current information of the switch on the opposite side of the station, it can be determined whether the line is overloaded or overloaded, realizing the targeted determination of the status information and improving the determination accuracy and efficiency of the status information.

[0086] Figure 3 It is a schematic flowchart of a method for determining the line status provided in the embodiment of the present application. This embodiment is in Figure 1Based on the embodiments, a method for determining the state of a line will be described in detail.

[0087] As Figure 3 shown, the method includes:

[0088] S301. Determine the switch type of the switch to be confirmed.

[0089] Exemplarily, this step can refer to the above step S101 and will not be elaborated here.

[0090] S302. Determine the target switch from the line according to the switch type of the switch to be confirmed.

[0091] Exemplarily, this step can refer to the above step S102 and will not be elaborated here.

[0092] S303. Obtain the current information of the target switch and the current information of the switch in the opposite substation of the switch to be confirmed; wherein, the switch in the opposite substation represents the switch in the substation of the opposite line of the switch to be confirmed.

[0093] Exemplarily, this step can refer to the above step S103 and will not be elaborated here.

[0094] S304. Determine the sum value of the real-time current value of the target switch and the real-time current value of the switch in the opposite substation as the current sum value.

[0095] Exemplarily, the current information may include the real-time current value. For an automated switch, determining the real-time current value of the target switch is to determine the real-time current value of the switch to be confirmed itself; for a non-automated switch, determining the real-time current value of the target switch is to determine the real-time current value of the upstream switch.

[0096] Regardless of whether the switch to be confirmed is an automated switch or a non-automated switch, the real-time current value of the target switch and the real-time current value of the switch in the opposite substation are added together. The sum value obtained after addition is determined as the current sum value.

[0097] S305. If the current sum value is equal to or greater than the preset first current threshold, determine that the state information of the line is overloaded.

[0098] [[ID= ,]]Exemplarily, a first current threshold and a second current threshold are preset, where the first current threshold is greater than the second current threshold. For example, the first current threshold is 100% of the current limit value of the switch in the opposite substation, and the second current threshold is 80% of the current limit value of the switch in the opposite substation. That is, the preset current limit value of the switch in the opposite substation can be obtained, and the current limit value is a rated current value. The first current threshold and the second current threshold are determined according to the current limit value of the switch in the opposite substation.

[0099] Compare the current sum value with the first current threshold. If the current sum value is equal to or greater than the preset first current threshold, determine that the status information of the line is overloaded. For example, if the current sum value is equal to or greater than 100% of the current limit of the switch in the opposite substation, it is considered that the status information of the line is overloaded. If it is determined that the line is overloaded, an alarm message can also be sent. For example, the alarm message can be sent in the form of a pop-up prompt, and the content of the pop-up prompt can be "According to the real-time current, the line may be overloaded after power transfer".

[0100] S306. If the current sum value is equal to or greater than the preset second current threshold and less than the preset first current threshold, determine that the status information of the line is heavily loaded.

[0101] Exemplarily, after obtaining the current sum value, it can be determined whether the current sum value is equal to or greater than the preset second current threshold and less than the preset first current threshold. That is, it is determined whether the current sum value is between the second current threshold and the first current threshold. If the current sum value is equal to or greater than the preset second current threshold and less than the preset first current threshold, determine that the status information of the line is heavily loaded. For example, if the current sum value is equal to or greater than 80% of the current limit of the switch in the opposite substation and less than 100% of the current limit of the switch in the opposite substation, it is considered that the status information of the line is heavily loaded. If it is determined that the line is heavily loaded, an alarm message can also be sent. For example, the alarm message can be sent in the form of a pop-up prompt, and the content of the pop-up prompt can be "According to the real-time current, the line may be heavily loaded after power transfer".

[0102] If it is determined that the current sum value is less than the second current threshold, it is considered that the line is not heavily loaded or overloaded and can continue to operate normally.

[0103] The method for determining the line status provided by the embodiments of the present application can determine a target switch from the line for different types of switches by determining the switch type of the switch to be confirmed. Different target switches can be determined for different switch types. When determining whether there is heavy overload, the current information of the target switch and the current information of the switch in the opposite substation of the switch to be confirmed can be obtained, and then whether the line is heavily loaded or overloaded can be determined according to the current information of the target switch and the current information of the switch in the opposite substation, so as to realize the targeted determination of the status information and improve the determination accuracy of the status information.

[0104] Figure 4 is a schematic flowchart of a method for determining the line status provided by the embodiments of the present application. On the basis of Figure 1 the embodiments, a method for determining the line status is described in detail.

[0105] As Figure 4 shown, the method includes:

[0106] S401. Determine the switch type of the switch to be confirmed.

[0107] Exemplarily, this step can refer to step S101 above and will not be elaborated here.

[0108] S402. Determine the target switch from the line according to the switch type of the switch to be confirmed.

[0109] Exemplarily, this step can refer to step S102 above and will not be elaborated here.

[0110] S403. Obtain the current information of the target switch and the current information of the switch in the substation on the opposite side of the switch to be confirmed; wherein, the switch in the substation on the opposite side represents the switch in the substation of the line on the opposite side of the switch to be confirmed.

[0111] Exemplarily, this step can refer to step S103 above and will not be elaborated here.

[0112] S404. For each historical moment, determine the sum value of the historical current value of the target switch and the historical current value of the switch in the substation on the opposite side as the historical sum value.

[0113] Exemplarily, the current values of each switch at different moments can be stored. The current information can include the historical current values corresponding to a preset number of historical moments. For example, a historical time period can be preset, which includes multiple historical moments, and the current value at that time corresponding to the historical moment is the historical current value. For example, if the preset historical time period is 30 days, the historical current values at 24:00 every day in the past 30 days can be obtained.

[0114] The historical current values can be stored in the form of a curve, where the abscissa of the curve represents time and the ordinate represents the current value. The current curve of the target switch in the past 30 days can be obtained, and the current curve of the switch in the substation on the opposite side in the past 30 days can be obtained. The current curve includes the historical current values corresponding to each historical moment.

[0115] For any historical moment, obtain the historical current value of the target switch at that historical moment and the historical current value of the switch in the substation on the opposite side at that historical moment. For each historical moment, add the historical current value of the target switch and the historical current value of the switch in the substation on the opposite side to obtain the historical sum value at that historical moment. For the form of the current curve, the two current curves can be superimposed, that is, the two historical current values at the same moment are superimposed.

[0116] S405. Determine the target sum value according to the historical sum values corresponding to each historical moment.

[0117] Exemplarily, historical sum values corresponding to respective historical moments are determined, and based on these historical sum values, a target sum value is determined. For example, the average value of these historical sum values can be used as the target sum value. In this embodiment, the maximum value among these historical sum values is determined as the target sum value. The historical moment corresponding to the target sum value is determined. For example, the historical moment corresponding to the target sum value is XX:XX on XX / XX.

[0118] S406. If the target sum value is equal to or greater than a preset first current threshold, determine that the status information of the line is overloaded.

[0119] Exemplarily, a first current threshold and a second current threshold are preset, where the first current threshold is greater than the second current threshold. For example, the first current threshold is 100% of the current limit of the switch in the opposite substation, and the second current threshold is 80% of the current limit of the switch in the opposite substation. That is, the preset current limit of the switch in the opposite substation can be obtained, and the current limit is a rated current value. Based on the current limit of the switch in the opposite substation, the first current threshold and the second current threshold are determined.

[0120] Compare the target sum value with the first current threshold. If the target sum value is equal to or greater than the preset first current threshold, determine that the status information of the line is overloaded. For example, if the target sum value is equal to or greater than 100% of the current limit of the switch in the opposite substation, it is considered that the status information of the line is overloaded. If it is determined that the line is overloaded, an alarm message can also be sent. For example, the alarm message can be sent in the form of a pop-up prompt, and the content of the pop-up prompt can be "According to the historical current at XX:XX on XX / XX, the line may be overloaded after power transfer".

[0121] S407. If the target sum value is equal to or greater than the preset second current threshold and less than the preset first current threshold, determine that the status information of the line is heavily loaded.

[0122] Exemplarily, after obtaining the target sum value, it can be determined whether the target sum value is equal to or greater than the preset second current threshold and less than the preset first current threshold. That is, it is determined whether the target sum value is between the second current threshold and the first current threshold. If the target sum value is equal to or greater than the preset second current threshold and less than the preset first current threshold, determine that the status information of the line is heavily loaded. For example, if the target sum value is equal to or greater than 80% of the current limit of the switch in the opposite substation and less than 100% of the current limit of the switch in the opposite substation, it is considered that the status information of the line is heavily loaded. If it is determined that the line is heavily loaded, an alarm message can also be sent. For example, the alarm message can be sent in the form of a pop-up prompt, and the content of the pop-up prompt can be "According to the historical current at XX:XX on XX / XX, the line may be heavily loaded after power transfer".

[0123] If it is determined that the target sum value is less than the second current threshold, it is considered that the line is not overloaded or overloaded, and normal operation can continue.

[0124] The method for determining the line state provided by the embodiments of the present application can determine a target switch from the line for different types of switches by determining the switch type of the switch to be confirmed. Different target switches can be determined for different switch types. When judging whether there is overloading, the current information of the target switch and the current information of the switch on the opposite side of the switch to be confirmed in the substation can be obtained, and then whether the line is overloaded or overloaded can be determined according to the current information of the target switch and the current information of the switch on the opposite side of the substation, so as to realize the targeted determination of the state information and improve the determination accuracy of the state information.

[0125] Figure 5 It is a schematic flowchart of a method for determining the line state provided by the embodiments of the present application. On the basis of Figure 1 the embodiments, a method for determining the line state is described in detail.

[0126] As Figure 5 shown, the method includes:

[0127] S501. Determine the switch type of the switch to be confirmed.

[0128] Exemplarily, this step can refer to the above step S101 and will not be elaborated here.

[0129] S502. Determine the target switch from the line according to the switch type of the switch to be confirmed.

[0130] Exemplarily, this step can refer to the above step S102 and will not be elaborated here.

[0131] S503. Obtain the current information of the target switch and the current information of the switch on the opposite side of the switch to be confirmed in the substation; wherein, the switch on the opposite side of the substation represents the switch in the substation on the opposite side of the line of the switch to be confirmed.

[0132] Exemplarily, this step can refer to the above step S103 and will not be elaborated here.

[0133] S504. Determine the state information of the line according to the current information of the target switch and the current information of the switch on the opposite side of the substation; wherein, the state information represents whether the line is overloaded or overloaded after power transfer.

[0134] Exemplarily, this step can refer to the above step S104 and will not be elaborated here.

[0135] S505. For a non-automated switch, if it is determined that the line status information is overloaded or heavily loaded based on the current information of the target switch and the current information of the switch in the opposite substation, then determine the upstream switch and the downstream switch of the switch to be confirmed on the line; wherein, the upstream switch represents the first automated switch adjacent to the switch to be confirmed and located upstream of the switch to be confirmed on the line, and the downstream switch represents the first automated switch adjacent to the switch to be confirmed and located downstream of the switch to be confirmed on the line.

[0136] Exemplarily, if the switch to be confirmed is a non-automated switch, after determining that the line status information is overloaded or heavily loaded based on the current information of the target switch and the current information of the switch in the opposite substation, the line status information can be further verified to determine whether the line status information is truly overloaded or heavily loaded.

[0137] Determine the upstream switch and the downstream switch of the switch to be confirmed on the line. The upstream switch refers to the first automated switch adjacent to the switch to be confirmed and located upstream of the switch to be confirmed on the line, and the downstream switch refers to the first automated switch adjacent to the switch to be confirmed and located downstream of the switch to be confirmed on the line. As Figure 2 shown, if the switch to be confirmed is the non-automated switch B, then the upstream switch is the in-station switch A, and the downstream switch is the automated switch C.

[0138] In this embodiment, both the upstream switch and the downstream switch are on the same side of the line as the switch to be confirmed. For Figure 2 example, the upstream switch, the downstream switch, and the switch to be confirmed are all on the left side of the tie switch E. If there is no automated switch between the switch to be confirmed and the tie switch, then the tie switch can be used as the downstream automated switch. For example, if the switch to be confirmed is the non-automated switch D, then the upstream switch is the automated switch C, and the downstream switch is the tie switch E.

[0139] S506. Obtain the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer; wherein, the upstream distribution transformer represents the distribution transformer between the upstream switch and the switch to be confirmed, and the downstream distribution transformer represents the distribution transformer between the switch to be confirmed and the downstream switch.

[0140] Exemplarily, both the upstream switch and the downstream switch are automated switches. Therefore, the real-time current value of the upstream switch and the real-time current value of the downstream switch can be directly obtained. For the tie switch, the current value is always 0.

[0141] One or more distribution transformers may be deployed between two adjacent switches in the line. The distribution transformer between the upstream switch and the switch to be confirmed can be determined as the upstream distribution transformer, and the distribution transformer between the switch to be confirmed and the downstream switch can be determined as the downstream distribution transformer. Obtain the real-time current value of each upstream distribution transformer and the real-time current value of each downstream distribution transformer. It is also possible to determine the sum of the real-time current values of these upstream distribution transformers as the total real-time current value of the upstream distribution transformers, and determine the sum of the real-time current values of these downstream distribution transformers as the total real-time current value of the downstream distribution transformers.

[0142] S507. Verify the status information of the line according to the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer.

[0143] Exemplarily, determine the status information of the line according to the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer. If the determined status information of the line is consistent with the status information determined in S504, then determine this status information as the final status information; if the determined status information of the line is inconsistent with the status information determined in S504, it can be considered that there is a problem with the status information determined in S504, and a prompt message is sent to the staff to remind the staff to conduct a review. It is also possible to determine the status information determined according to the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer as the final status information.

[0144] For example, determine the status information determined in S504 as the first status information, and determine the status information determined according to the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer as the second status information. If the first status information is overload and the second status information is heavy load, then determine the status information of the line as heavy load.

[0145] The determination rule of the second status information can be preset. According to the preset determination rule, calculate the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer to obtain the second status information. In this embodiment, the determination rule of the second status information is not specifically limited. Through secondary confirmation, the accuracy of status determination based on non-automated switches can be improved.

[0146] In this embodiment, the status information of the line is verified according to the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer, including: determining the predicted current value of the switch to be confirmed according to the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer; wherein, the predicted current value represents the predicted real-time current value; determining the sum value of the predicted current value of the switch to be confirmed and the real-time current value of the switch in the opposite substation; if the sum value of the predicted current value of the switch to be confirmed and the real-time current value of the switch in the opposite substation is equal to or greater than the preset first current threshold, it is verified that the status information of the line is overloaded.

[0147] Specifically, the switch to be confirmed is a non-automated switch and the real-time current value cannot be directly collected. The real-time current value of the switch to be confirmed can be predicted according to the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer, and the predicted real-time current value is determined as the predicted current value.

[0148] According to the positions of the switches on the line, it can be determined that the real-time current value of the upstream switch should be greater than the real-time current value of the switch to be confirmed, and the real-time current value of the switch to be confirmed should be greater than the real-time current value of the downstream switch. Therefore, the predicted current value can be determined as a value between the real-time current value of the upstream switch and the real-time current value of the downstream switch. The predicted value can also be adjusted according to the real-time current value of the upstream distribution transformer and the real-time current value of the downstream distribution transformer to obtain the final predicted current value.

[0149] The predicted current value of the switch to be confirmed should be between the real-time current value of the upstream switch and the real-time current value of the downstream switch. If the predicted current value is greater than the real-time current value of the upstream switch or less than the real-time current value of the downstream switch, a pop-up window can be prompted with "The real-time current of the non-automated switch is XXX, and this data may be incorrect", and no subsequent status determination is performed.

[0150] If the predicted current value is between the real-time current value of the upstream switch and the real-time current value of the downstream switch, the predicted current value of the switch to be confirmed and the real-time current value of the switch in the opposite substation can be added together, and the calculated sum value is determined as the predicted sum value.

[0151] A first current threshold and a second current threshold are preset, where the first current threshold is greater than the second current threshold. For example, the first current threshold is 100% of the current limit of the switch in the opposite substation, and the second current threshold is 80% of the current limit of the switch in the opposite substation. That is, the preset current limit of the switch in the opposite substation can be obtained, and the current limit is a rated current value. Based on the current limit of the switch in the opposite substation, the first current threshold and the second current threshold are determined. Compare the predicted sum value with the first current threshold. If the predicted sum value is equal to or greater than the preset first current threshold, determine that the status information of the line is overloaded. For example, if the predicted sum value is equal to or greater than 100% of the current limit of the switch in the opposite substation, it is considered that the status information of the line is overloaded. If it is determined that the line is overloaded, an alarm message can be sent. For example, the alarm message can be sent in the form of a pop-up prompt, and the content of the pop-up prompt can be "The real-time current of the non-automated switch is XXX. According to the real-time current, the line may be overloaded after power transfer".

[0152] The beneficial effect of such a setting is to predict the real-time current value of the non-automated switch, re-determine the status information of the line, realize targeted judgment and further confirmation of the non-automated switch, and improve the judgment accuracy.

[0153] In this embodiment, it further includes: if the sum value of the predicted current value of the switch to be confirmed and the real-time current value of the switch in the opposite substation is equal to or greater than the preset second current threshold and less than the preset first current threshold, it is verified that the status information of the line is overloaded.

[0154] Specifically, determine whether the predicted sum value is equal to or greater than the preset second current threshold and less than the preset first current threshold. That is, determine whether the predicted sum value is between the second current threshold and the first current threshold. If the predicted sum value is equal to or greater than the preset second current threshold and less than the preset first current threshold, determine that the status information of the line is overloaded. For example, if the predicted sum value is equal to or greater than 80% of the current limit of the switch in the opposite substation and less than 100% of the current limit of the switch in the opposite substation, it is considered that the status information of the line is overloaded. If it is determined that the line is overloaded, an alarm message can be sent. For example, the alarm message can be sent in the form of a pop-up prompt, and the content of the pop-up prompt can be "The real-time current of the non-automated switch is XXX. According to the real-time current, the line may be overloaded after power transfer".

[0155] If it is determined that the current sum value is less than the second current threshold, it is considered that the line is not overloaded or overloaded and can continue to operate normally. A pop-up prompt can be sent as "The real-time current of the non-automated switch is XXX. Power transfer can be performed according to the real-time current".

[0156] The beneficial effect of such a setting is to avoid misconfirmation of overload or overloading through secondary determination and improve the determination accuracy of the status information.

[0157] In this embodiment, the predicted current value of the switch to be confirmed is determined according to the real-time current value of the upstream switch, the real-time current value of the downstream switch, the real-time current value of the upstream distribution transformer, and the real-time current value of the downstream distribution transformer, including: determining a first current value according to the real-time current value of the upstream switch and the real-time current value of the upstream distribution transformer; wherein, the first current value represents the difference between the real-time current value of the upstream switch and the real-time current value of the upstream distribution transformer; determining a second current value according to the real-time current value of the downstream switch and the real-time current value of the downstream distribution transformer; wherein, the second current value represents the sum value between the real-time current value of the downstream switch and the real-time current value of the downstream distribution transformer; determining the predicted current value of the switch to be confirmed according to the first current value and the second current value.

[0158] Specifically, there may be multiple distribution transformers between the upstream switch and the switch to be confirmed, and the real-time current value of the upstream distribution transformer may be the sum of the real-time currents of these distribution transformers between the upstream switch and the switch to be confirmed; there may be multiple distribution transformers between the downstream switch and the switch to be confirmed, and the real-time current value of the downstream distribution transformer may be the sum of the real-time currents of these distribution transformers between the downstream switch and the switch to be confirmed. As Figure 2 shown, the real-time current value of distribution transformer a is Ia, the real-time current value of distribution transformer b is Ib, the real-time current value of distribution transformer c is Ic, and the real-time current value of distribution transformer d is Id. The real-time current value of the upstream distribution transformer is Ia + Ib, and the real-time current value of the downstream distribution transformer is Ic + Id.

[0159] Subtract the real-time current value of the upstream switch from the real-time current value of the upstream distribution transformer to obtain the first current value. For example, if the upstream switch is switch A in the substation and the real-time current value is IA, then the first current value I1 = IA - (Ia + Ib).

[0160] Add the real-time current value of the downstream switch and the real-time current value of the downstream distribution transformer to obtain the second current value. For example, if the upstream switch is automated switch C and the real-time current value is IC, then the second current value I2 = IC + (Ic + Id).

[0161] Calculate the predicted current value of the switch to be confirmed according to the first current value and the second current value. For example, the predicted current value may be the average of the first current value and the second current value. If the switch to be confirmed is non-automated switch B, then the predicted current value IB = (I1 + I2) / 2.

[0162] The beneficial effect of such a setting is that by considering the real-time current values of the upstream and downstream automated switches and the real-time current values of the upstream and downstream distribution transformers, the determination accuracy of the predicted current value is improved, and thus the determination accuracy of the line state is improved.

[0163] Figure 6Schematic diagram of switch layout on the line provided by the embodiment of the present application Figure 6 There are branches in the line in Figure 6 . For example, there is a branch between the in-station switch A and the non-automated switch B, and there is a branch between the non-automated switch B and the automated switch C. If the switch type of the switch to be confirmed is a non-automated switch, the target switch can be determined based on the line where the non-automated switch is located, that is, including the main line and relevant branch lines. If it is determined that the line status information is overloaded or overloaded based on the current information of the target switch and the current information of the switch in the opposite in-station, the upstream switch and the downstream switch of the switch to be confirmed can be determined from the line. The upstream switch is the first automated switch on the upstream main line of the switch to be confirmed, and the downstream switch is the first automated switch on the upstream main line of the switch to be confirmed. The first automated switch on the relevant branch line between the switch to be confirmed and the upstream switch can also be determined as the upstream branch switch, and the first automated switch on the relevant branch line between the switch to be confirmed and the downstream switch can be determined as the downstream branch switch. If the current data detected by the automated switch on the searched branch line is abnormal, the current information of the automated switch is not included in the calculation, and continue to search for the automated switch downward until reaching the tie switch at the open position or the end of the line. The tie switch and the end of the line are calculated as current 0. Based on the current information of the upstream switch, the current information of the upstream branch switch, the current information of the distribution transformer between the switch to be confirmed and the upstream switch, the current information of the distribution transformer between the switch to be confirmed and the upstream branch switch, the current information of the downstream switch, the current information of the downstream branch switch, the current information of the distribution transformer between the switch to be confirmed and the downstream switch, and the current information of the distribution transformer between the switch to be confirmed and the downstream branch switch, the current information of the switch to be confirmed can be determined.

[0164] For example, the switch to be confirmed is B, the upstream switch is A, the downstream switch is C, and the upstream branch switch is H. Since the current data of the automated switch J is abnormal, the downstream branch switch is K downstream of J. IB = (I1 + I2) / 2, where I1 is obtained based on the current information of the upstream switch, the current information of the upstream branch switch, the current information of the distribution transformer between the switch to be confirmed and the upstream switch, and the current information of the distribution transformer between the switch to be confirmed and the upstream branch switch. I1 is the current of the upstream switch minus the current of the upstream branch switch on all branch lines between the upstream switch and the switch to be confirmed, and minus the current of the distribution transformer between each switch. The distribution transformers between A and B are a and b, and the distribution transformer between B and H is h, that is, I1 = IA - IH - (Ia + Ib + Ih).

[0165] I2 is obtained based on the current information of the downstream switch, the current information of the downstream branch switch, the current information of the distribution transformer between the switch to be confirmed and the downstream switch, and the current information of the distribution transformer between the switch to be confirmed and the downstream branch switch. I2 is the sum of the current of the downstream switch, the currents of the downstream branch switches on all branches between the switch to be confirmed and the downstream switch, and the currents of the distribution transformers between each pair of switches. The distribution transformer between B and C is c and d, and the distribution transformer between B and K is k and o, that is, I2 = IC + IK + (Ic + Id + Ik + Io). The current accuracy of the automatic switch is relatively high, while the current accuracy of the distribution transformer is relatively low. In this embodiment, the current of the distribution transformer can be involved in the calculation as little as possible, so as to improve the accuracy of the non-automatic switch current calculation.

[0166] The method for determining the line state provided by the embodiment of the present application can determine a target switch from the line for different types of switches by determining the switch type of the switch to be confirmed. Different target switches can be determined for different switch types. When determining whether there is overloading or heavy loading, the current information of the target switch and the current information of the switch in the opposite substation of the switch to be confirmed can be obtained, and then whether the line is heavily loaded or overloaded can be automatically determined according to the current information of the target switch and the current information of the switch in the opposite substation, so as to achieve targeted determination of the status information and improve the accuracy and efficiency of the status information determination.
