Description

Technical Field

[0001] The present application relates to the technical field of digital distribution network, and in particular to a method and system for digital five-defense safety management and control of overhead lines in a distribution network. Background Art

[0002] During the operation and management of power grid equipment, it is necessary to manage and operate various types of electrical equipment, such as operating various switches, transformers and other equipment in substations in sequence. With the continuous development of power grid system management technology, power grid operation and maintenance personnel can realize online monitoring and management of substation electrical equipment through intelligent operation platforms.

[0003] There are strict operating procedures for a series of operations in substation equipment maintenance. These operating procedures have a strict sequence and strict operating logic. Once the operating procedures are confused or handled incorrectly, the operational risks will be greatly increased.

[0004] In order to reduce the accuracy of the sequence of operating steps of power grid equipment, the operator clearly specifies the operating steps to be performed in advance, and then performs preliminary operations on the cloud management system in advance, that is, enter the correct operating steps in the cloud management system in sequence, generate an operation ticket, and then import the correct operation ticket into the mobile terminal. The operator then carries the mobile terminal to the equipment site and performs the operation according to each step of the mobile terminal's instructions (screen display instructions and voice instructions are synchronized) to ensure the accuracy of the sequence of operating steps.

[0005] However, in the process of operators entering operating steps through the cloud management system, it is inevitable that incorrect operating steps will be entered, that is, there is a possibility of safety accidents when two adjacent steps are run in sequence. If the operator operates the equipment according to the operation ticket that includes incorrect steps, it will endanger the operator's personal safety and the stable operation of the equipment. Summary of the invention

[0006] In order to reduce the possibility of operators entering incorrect operating steps, the present application provides a method and system for digital five-defense safety management and control of overhead lines in a distribution network.

[0007] In the first aspect, the present application provides a digital five-defense safety management and control method based on overhead lines of a distribution network, which adopts the following technical solutions: A digital five-defense safety management and control method for overhead lines of a distribution network, comprising: Establish each operation step and its mutually exclusive set of steps; Establish a mapping relationship between each operation step and the corresponding set of exclusive steps; Every time an operation step is added, the previous step of the new step is obtained; Based on the previous step, identifying a set of exclusive steps corresponding to the previous step; In the exclusive step set corresponding to the previous step, matching the exclusive step corresponding to the newly added step; If the match is successful, an alarm message is generated and step addition is frozen. If the match is unsuccessful, step addition is enabled.

[0008] Through the above technical solution, each electrical operation step is analyzed in advance to find out the operation steps that may cause safety accidents if the operation step is continuously performed, that is, the repulsive steps. The set of multiple repulsive steps is called a repulsive step set.

[0009] After the establishment of the mutually exclusive step set, a mapping relationship between each operation step and the mutually exclusive step set is established, that is, a certain operation step and the mutually exclusive step set containing the mutually exclusive steps are associated with each other. When the operator enters the operation steps in the operation ticket, each time an operation step is added, the previous step of the added step is obtained (that is, the previous step and the added step are adjacent, the previous step is in front, and the added step is in the back).

[0010] Based on the previous step, a match is performed in the exclusive step set corresponding to the previous step to determine whether the exclusive step set contains the exclusive step corresponding to the newly added step. If the match is successful, it means that the exclusive step set contains the exclusive step corresponding to the newly added step, that is, the previous step and the newly added step are mutually exclusive steps. If they are executed sequentially, there are certain security risks, and further verification by the operator is required. At this time, an alarm message is generated and the step addition is frozen to facilitate the operator to verify whether the newly added step is correct and prevent the addition of further erroneous steps. Further operations can be performed only after verification.

[0011] If the match is unsuccessful, it means that the exclusive step set does not contain the exclusive step corresponding to the newly added step, that is, the previous step and the newly added step are not mutually exclusive steps, and there is no security risk in executing them in sequence. At this time, the step addition is opened to facilitate further input of operation steps.

[0012] By checking whether each new operation step is mutually exclusive with the previous step, the possibility of operators entering incorrect operation steps is reduced, thereby reducing the operational risks of the electrical operation process and improving the stability of substation equipment operation.

[0013] In a preferred example, the present application may be further configured as follows: after each newly added operation step, the following steps may be further included: If the newly added operation step is the first step of the operation ticket, the step will be directly opened for addition.

[0014] According to the above technical solution, if the newly added step is the first operation step of the operation ticket, and there is no previous step of the newly added step, the previous technical solution cannot be executed. It is determined whether the newly added step is the first step and whether to perform the exclusive step check. That is, if the newly added step is the first step, then the step is directly opened for addition. If the newly added step is not the first step, then the exclusive step check of the newly added step is performed.

[0015] In a preferred example, the present application can be further configured to, after adding the additional steps, further include: Based on the newly added steps, identifying a set of exclusive steps corresponding to the newly added steps; Among the optional steps after the newly added step, the optional steps corresponding to the exclusive steps in the exclusive step set are marked with warnings; Based on the warning mark, the optional steps after the newly added step are divided into warning steps and regular steps; If the re-added step is a regular step, the step is opened for addition; if the re-added step is a warning step, an exclusive check is performed based on the re-added step and the newly added step.

[0016] Through the above technical solution, after the operator completes the addition of the new step, before adding the next step, it takes a short period of time to know the specific steps of the next step. Within this time interval, the system identifies the set of exclusive steps associated with the new step based on the new step.

[0017] Then, in the optional steps after the newly added step, the optional steps corresponding to the exclusive steps in the exclusive step set will be marked with warning marks, that is, among the optional steps, the optional steps that are exclusive to the newly added steps will be marked with warning marks, and the optional steps that are not marked with warning marks will be regular steps. If the re-added step is a regular step, the step will be opened for addition. If the re-added step is a warning step, an exclusive check will be performed based on the re-added step and the newly added step.

[0018] By performing early warning analysis on optional steps, we can determine which steps are risky to add and which are risk-free. This can provide operators with risk estimates for adding steps and improve the efficiency of adding steps and generating operation tickets.

[0019] In a preferred example, the present application may be further configured as follows: after the previous step of obtaining the newly added step, the following steps may be further included: If the newly added step has multiple corresponding previous steps, based on the multiple previous steps, identifying a set of exclusive steps corresponding to the multiple previous steps; In the plurality of mutually exclusive step sets, matching mutually exclusive steps corresponding to the newly added steps; If only one exclusive step is matched, an alarm message is generated and step addition is frozen. If the match is unsuccessful, step addition is enabled.

[0020] After a certain operation step, there may be multiple parallel operation steps. After the execution of multiple parallel operation steps, they are gathered together to execute the next step. Through the above technical solution, if there are multiple previous steps for a new step, the set of mutually exclusive steps corresponding to the multiple previous steps is obtained, and the mutually exclusive steps corresponding to the new step are matched in the multiple mutually exclusive step sets. If only one mutually exclusive step is matched, an alarm message is generated and the step addition is frozen. If the match is unsuccessful, the step addition is opened. Through this technical solution, the processing of multiple previous steps is improved to expand the scope of application of this technical solution.

[0021] In a preferred example, the present application can be further configured such that if multiple identical exclusive steps are matched, and the multiple identical exclusive steps are distributed in more than two exclusive step sets, it is prohibited to enter the new steps in the operation ticket.

[0022] Through the above technical solution, if multiple identical exclusive steps are matched in multiple exclusive step sets, and multiple identical exclusive steps are distributed in more than two exclusive step sets, it means that the added new step is a common exclusive step of multiple previous steps. If this new step is executed after multiple previous steps, the operational safety risk will be further increased. At this time, it is directly prohibited to enter the new step in the operation ticket, which reduces the possibility of generating and importing erroneous operation tickets into the mobile terminal, and improves the safety of electrical equipment operation.

[0023] In a preferred example, the present application may be further configured as follows: after prohibiting the entry of the new step in the operation ticket, the method further includes: Obtain the operation account information of the prohibited operation ticket; Based on the operation account information, obtain the time span between the last and current prohibition on entering operation tickets; Based on the time span, the security operation level of the current operating account is evaluated.

[0024] Through the above technical solution, after a situation occurs in which it is prohibited to enter new steps in the operation ticket, the operating account information in which the situation occurs is obtained, including the information of the operating account, the historical records of the operating account in the past (including the corresponding time of each occurrence of the situation, the time interval between two adjacent occurrences of the situation, etc.).

[0025] After obtaining the time span between the last and current prohibited operation ticket entry situations (that is, the time interval between two consecutive occurrences of this situation), the security operation level of the current operation account is evaluated. It can be simply understood as follows: the shorter the time interval, the higher the frequency of erroneous operations of the operation account in a short period of time, and the lower the security operation level; conversely, the longer the time interval between two consecutive erroneous operations, the lower the frequency of erroneous operations, and the higher the security operation level.

[0026] In a preferred example, the present application may be further configured as follows: the evaluation of the security operation level of the current operation account includes: Based on multiple preset time span intervals, a mapping relationship between multiple safety factors and multiple time span intervals is established; Get the time span when the current operating account is prohibited from entering operation tickets; Based on the time span, identifying a time span interval to which the time span belongs; Based on the time span interval, obtaining a safety factor corresponding to the time span interval; Based on the safety factor, a safety operation level assessment is performed on the current operating account.

[0027] Through the above technical solution, by presetting multiple time span intervals and setting a corresponding safety factor for each time span interval, that is, establishing a mapping relationship between multiple safety factors and multiple time span intervals, for example, for a certain time span interval (such as 15 days-30 days), the safety factor corresponding to the time span interval is 0.7, and the larger the time span, the higher the safety factor.

[0028] According to the specific time of the last and current erroneous operations of the current operating account, the time span is calculated, and the time span interval in which the time span is located is identified, and then the safety factor corresponding to the time span interval can be calculated. At this time, the safety factor and other information of the operating account can be combined to calculate the safe operation level of the operating account, so that the system can comprehensively evaluate and understand the electrical operation safety of different operators according to the safe operation level.

[0029] In the second aspect, based on the above-mentioned method for digital five-defense safety management and control of overhead lines in a distribution network, the present application provides a digital five-defense safety management and control system based on overhead lines in a distribution network, which adopts the following technical solution.

[0030] A digital five-defense safety management and control system based on overhead lines of distribution network, comprising: Step set establishment module: used to establish each operation step and the exclusive step set that is exclusive to it; Mapping relationship establishment module: used to establish the mapping relationship between each operation step and the corresponding exclusive step set; Acquisition module: used to obtain the previous step of the newly added step; Identification module: used to identify the set of exclusive steps corresponding to the previous step; Matching module: used for matching the exclusive step corresponding to the newly added step in the exclusive step set corresponding to the previous step.

[0031] In summary, this application includes the following beneficial technical effects: 1. Check whether each newly added operation step is mutually exclusive with the previous step to reduce the possibility of operators entering incorrect operation steps, thereby reducing the operational risks of the electrical operation process and improving the stability of substation equipment operation; 2. Through early warning analysis of optional steps after the newly added steps, it is possible to determine which steps are risky and which are risk-free, thereby providing operators with risk estimates for adding steps and improving the efficiency of adding steps and generating operation tickets; 3. Based on the time span between two consecutive times when the operation account was prohibited from entering new steps into the operation ticket, the safety factor of the operation of the corresponding operation account is obtained, so as to combine the safety factor and other information of the operation account to calculate the safe operation level of the operation account, and based on the safe operation level, conduct a comprehensive assessment and understanding of the electrical operation safety of different operators.

[0039] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0040] The embodiments of the present application disclose a five-defense safety control method based on digitalization of overhead lines of a distribution network and a five-defense safety control system based on digitalization of overhead lines of a distribution network. The execution subject of the five-defense safety control method described herein may be a five-defense safety control system.

[0041] Refer to the attached Figure 1 As shown, a digital five-defense safety management and control method based on overhead lines of a distribution network includes the following processing steps: S101. Establish each operation step and its mutually exclusive step set.

[0042] In implementation, based on the operating logic and basic specifications of the electrical equipment, each electrical operation step is analyzed in advance to obtain the operation steps that may lead to safety accidents if operated continuously with the operation step, that is, the exclusive steps. The collection of multiple exclusive steps is called an exclusive step set.

[0043] Here, mutually exclusive steps and mutually exclusive step sets are further explained.

[0044] For example, for step A, according to the operating logic and operating specifications of the electrical equipment, if B, C, and D or three operating steps are executed immediately after step A, a safety accident may occur. In this case, the three categories or three operating steps of B, C, and D are respectively called the exclusive steps of step A, and the step set of the three categories or three operating steps of B, C, and D is called the exclusive step set of step A.

[0045] For the operation process of entering the operation ticket for substation electrical equipment, entering a certain operation step is not simply entering text, but the Chinese meaning corresponding to each specific operation step (that is, the steps that the operator can see through the computer or mobile terminal) has a certain sentence framework, which can be simply understood as follows.

[0046] For example, to open the 3# isolating switch in area A, the basic sentence framework after removing the specific area code, switch code, etc. is to open or close a certain # isolating switch in a certain area, and the operating steps and mutually exclusive steps described in the technical solution can be either a specific operating step or a basic sentence framework of the operating steps.

[0047] S102: Establish a mapping relationship between each operation step and a corresponding set of mutually exclusive steps.

[0048] In implementation, after the mutually exclusive step set is established, a mapping relationship between each operation step and the corresponding mutually exclusive step set is established, that is, a certain operation step and the mutually exclusive step set containing the mutually exclusive step are associated with each other.

[0049] S103. For each newly added operation step, the previous step of the newly added step is obtained.

[0050] In implementation, when the operator inputs the operation steps in the operation ticket, each time a new operation step is added, the previous step of the new step is obtained (that is, the previous step and the new step are adjacent, with the previous step in front and the new step in the back).

[0051] If a new step has multiple processing situations of the previous step, it will be explained in detail later.

[0052] S104. Based on the previous step, identify a set of exclusive steps corresponding to the previous step.

[0053] In implementation, after obtaining the previous step of the newly added step, based on the previous step, an exclusive step set corresponding to the previous step is identified, and the exclusive step set includes exclusive steps that are exclusive to the previous step.

[0054] S105. In the exclusive step set corresponding to the previous step, match the exclusive step corresponding to the newly added step.

[0055] In implementation, in the exclusive step set, the exclusive steps corresponding to the newly added steps are matched, that is, the basic sentence framework of the previous step is simplified and parsed first. For example, the previous step is: open the 3# disconnector in area A, then the basic sentence framework of the step after simplification and analysis is: open or close a certain #disconnector in a certain area, and there are multiple exclusive steps in the exclusive step set that are exclusive of the above basic sentence framework. At this time, in the exclusive step set of the previous step, the exclusive steps with the same basic sentence framework as the newly added step are matched.

[0056] S106. If the match is successful, an alarm message is generated and step addition is frozen. If the match is unsuccessful, step addition is enabled.

[0057] During implementation, if the match is successful, it means that the exclusive step set contains the exclusive step corresponding to the newly added step, that is, the previous step and the newly added step are mutually exclusive steps. If they are executed sequentially, there are certain security risks, which require further verification by the operator. At this time, an alarm message is generated and the step addition is frozen to facilitate the operator to verify whether the newly added step is correct and prevent the addition of further erroneous steps. Further operations can be performed only after verification.

[0058] If the match is unsuccessful, it means that the exclusive step set does not contain the exclusive step corresponding to the newly added step, that is, the previous step and the newly added step are not mutually exclusive steps, and there is no security risk in executing them in sequence. At this time, the step addition is opened to facilitate further input of operation steps.

[0059] In summary, by checking whether each new operation step is mutually exclusive with the previous step, the possibility of operators entering incorrect operation steps is reduced, thereby reducing the operational risks of the electrical operation process and improving the stability of substation equipment operation.

[0060] In addition, it should be emphasized that when the previous step is added and verified, generally speaking, there will be no repulsion between the current operation step and the subsequent interval step, because each verification has ruled out the possibility that the added step is a repulsive step.

[0061] Refer to the attached Figure 1 As shown, after each newly added operation step in step S103, the following steps are also included. If the newly added operation step is the first step of the operation ticket, the step is directly opened for addition.

[0062] In implementation, if the newly added step is the first operation step of the operation ticket, then there must be no previous step of the newly added step. By determining whether the newly added step is the first step, it is decided whether to perform the verification of the exclusive steps. That is, if the newly added step is the first step, then the step is directly opened for addition. If the newly added step is not the first step, the verification of the exclusive steps is performed.

[0063] Refer to the attached Figure 2 As shown, after adding the new steps, the following processing steps may also be included: S201. Based on the newly added steps, identify the set of exclusive steps corresponding to the newly added steps.

[0064] In practice, "after adding the new step" here means that the previous step and the new step have completed the mutual exclusion check, confirming that the new step has no operational risk. After the new step is added, the mutually exclusive step set corresponding to the new step is identified, that is, the mutually exclusive steps in the new step and the identified mutually exclusive step set, if executed one after the other, will have security risks.

[0065] S202. Among the optional steps after the newly added step, the optional steps corresponding to the exclusive steps in the exclusive step set are marked with warnings.

[0066] In implementation, for example, a new step is added, and the optional steps after step S include steps A, B, C, and D. The exclusive step set corresponding to the matched step S includes steps A and B. At this time, steps A and B are marked as warning steps.

[0067] S203: Based on the warning mark, the optional steps after the newly added steps are divided into warning steps and regular steps.

[0068] In implementation, continuing to understand according to the example in step S202, the optional steps after step S include steps A, B, C, and D, which are classified into early warning steps and regular steps according to whether there is repulsion. The early warning steps include steps A and B, and the regular steps are divided into C and D.

[0069] S204. If the re-added step is a regular step, the step is opened for addition. If the re-added step is a warning step, an exclusive check is performed based on the re-added step and the newly added step.

[0070] In implementation, if the re-added step is a regular step, the step addition is allowed. If the re-added step is a warning step, a mutual check is performed based on the re-added step and the newly added step. By performing a warning analysis on the optional steps, it is determined which steps are risky to add and which steps are risk-free. This can provide operators with a risk estimate for step addition, improve the efficiency of adding steps and generating operation tickets, and avoid efficiency losses caused by repeated operations (including re-adding steps and entering operation tickets).

[0071] Refer to the attached Figure 3 and attached Figure 6 As shown, in step S103, after obtaining the previous step of the newly added step, the following processing steps may also be included: S301. If a newly added step has multiple corresponding previous steps, based on the multiple previous steps, identify a set of exclusive steps corresponding to the multiple previous steps.

[0072] In practice, a certain operation step may be followed by multiple parallel operation steps. After the multiple parallel operation steps are completed, they are gathered together to execute the next step. Figure 6 As shown, the newly added step has two previous steps, and the two previous steps are parallel steps at the same level. The reason why there may be two previous steps is that the on-site execution of the operation ticket is usually performed by at least two people, one of whom is responsible for checking and reviewing the procedures, and the other is responsible for executing the parallel operation steps. Therefore, if there are multiple parallel previous steps, they can be executed by multiple operators. After the two previous steps are executed, the non-exclusive new steps can be executed.

[0073] Since each step has a preset corresponding set of mutually exclusive steps, multiple mutually exclusive step sets corresponding to it can be matched based on multiple previous steps. Figure 6As shown, the newly added step has two previous steps, and each previous step corresponds to an exclusive step set. The exclusive step set is represented by uppercase letters included in braces. This figure is only for ease of understanding and is not a limitation on the meaning and protection scope of the exclusive step set.

[0074] S302. In a plurality of mutually exclusive step sets, match mutually exclusive steps corresponding to the newly added steps.

[0075] S303: If only one exclusive step is matched, an alarm message is generated and step addition is frozen; if the match is unsuccessful, step addition is enabled.

[0076] In implementation, if only one mutually exclusive step is matched, the example of step S301 is continued, and the Figure 6 As shown, in the two exclusive step sets corresponding to the two previous steps, the exclusive steps corresponding to the newly added steps are matched, that is, the exclusive step set corresponding to the previous step on the left includes three exclusive steps A, B, and C, and the exclusive step set corresponding to the previous step on the right includes three exclusive steps D, E, and F. If the newly added step is any one of A, B, C, D, E, and F, an alarm message is generated and the step addition is frozen.

[0077] If the match is unsuccessful, refer to the attached Figure 6 As shown, the exclusive step set corresponding to the previous step on the left includes three exclusive steps A, B, and C, and the exclusive step set corresponding to the previous step on the right includes three exclusive steps D, E, and F. The newly added step is G, which is different from any of the steps A, B, C, D, E, and F, so the step is open for addition.

[0078] Refer to the attached Figure 7 As shown, if multiple identical exclusive steps are matched, and the multiple identical exclusive steps are distributed in more than two exclusive step sets, it is prohibited to enter the new steps in the operation ticket.

[0079] In implementation, the mutually exclusive step set corresponding to the previous step on the left includes three mutually exclusive steps A, B, and C, and the mutually exclusive step set corresponding to the previous step on the right includes three mutually exclusive steps A, E, and F. The two mutually exclusive step sets jointly include step A, which means that the added new step is a common mutually exclusive step of multiple previous steps. If this new step is executed immediately after multiple previous steps, the operational safety risk will further increase. At this time, it is directly prohibited to enter the new step in the operation ticket, thereby reducing the possibility of generating and importing erroneous operation tickets into the mobile terminal and improving the safety of electrical equipment operation.

[0080] Refer to the attached Figure 4 As shown, after prohibiting the entry of the additional steps in the operation ticket, the following processing steps may also be included: S401, obtaining the operation account information for which entry of the operation ticket is prohibited.

[0081] During implementation, after a situation occurs in which it is prohibited to enter new steps in the operation ticket, the operating account information where the situation occurs is obtained, including the operating account's ownership information, the operating account's previous historical records of the situation, the historical records including the corresponding time of each occurrence of the situation, the time interval between two adjacent occurrences of the situation, etc.

[0082] S402: Based on the operation account information, obtain the time span between the last time and the current time when the operation ticket entry is prohibited.

[0083] S403: Based on the time span, evaluate the security operation level of the current operating account.

[0084] In implementation, the shorter the time span, the higher the frequency of erroneous operations of the operating account in a short period of time, and the lower the safety operation level; conversely, the longer the time span between two adjacent erroneous operations, the lower the frequency of erroneous operations and the higher the safety operation level.

[0085] Refer to the attached Figure 5 As shown, in step S403, the security operation level of the current operating account is evaluated, which may include the following processing steps: S501: Based on multiple preset time span intervals, establish a mapping relationship between multiple safety factors and multiple time span intervals.

[0086] In implementation, a corresponding safety factor is set for each time span interval, that is, a mapping relationship between multiple safety factors and multiple time span intervals is established. For example, for a certain time span interval (such as 15 days to 30 days), the safety factor corresponding to the time span interval is 0.7. The larger the time span, the higher the safety factor.

[0087] S502: Obtain the time span during which the current operating account is prohibited from entering operation tickets.

[0088] During implementation, the time span is calculated based on the specific dates (which can also be specific to hours or minutes) corresponding to the current and last times that the current operating account was prohibited from entering operation tickets.

[0089] S503: Based on the time span, identify the time span interval to which the time span belongs.

[0090] S504: Based on the time span interval, obtain a safety factor corresponding to the time span interval.

[0091] S505. Based on the safety factor, a safety operation level assessment is performed on the current operating account.

[0092] During implementation, after the safety factor is obtained, the safety factor and other information of the operation account can be combined to calculate the safe operation level of the operation account, so that the system can comprehensively evaluate and understand the electrical operation safety of different operators based on the safe operation level.

[0093] Based on the above-mentioned method for digital five-defense safety management and control of overhead lines in a distribution network, the present application also provides a system for digital five-defense safety management and control of overhead lines in a distribution network, which adopts the following technical solution.
