Description

Technical Field

[0001] The present invention relates to the technical field of substation overhaul safety maintenance, and in particular to a power plant grounding wire management system and method. Background Art

[0002] Power station equipment maintenance refers to the regular inspection, repair, maintenance and replacement of various equipment in the power station to ensure the normal operation of the power station and extend the life of the equipment. The following are some common tasks of power station equipment maintenance: Regular equipment inspection and maintenance: According to the operating time and type of the equipment, it is regularly inspected and maintained to ensure that the equipment is in the best condition and can operate stably for a long time. Emergency repair and troubleshooting: When the equipment fails or has problems, timely repair and troubleshooting are carried out to ensure the normal operation of the power station. Installation and commissioning of new equipment: When new equipment is put into use, it is responsible for installation and commissioning to ensure that the equipment can operate normally and comply with relevant standards and regulations. Update and improvement of old equipment: According to the development of technology and changes in demand, old equipment is updated and improved to improve equipment efficiency and performance. Maintenance and management of equipment and tools: Responsible for the maintenance and management of various equipment and tools, such as hand tools, machine tools, measuring instruments, etc., to ensure that they are kept in good condition during use. Safety measures and procedures: Develop and implement a series of safety measures and procedures to ensure that personnel and the environment are protected from the risk of accidental injury or damage.

[0003] The safe and reliable operation of the power system is related to all aspects of the national economy, among which the safe and reliable operation of the substation is the top priority. The safe operation of the power system and substation requires the safety of equipment and personnel during operation. When the substation is under maintenance, in order to protect the safety of operators, it is necessary to use the technology of temporary grounding wires. The temporary grounding wire is hung on a grounding pile buried underground at one end to conduct the current underground when leakage occurs to ensure the safety of workers. This temporary grounding wire is an important tool for substation maintenance and operation and maintenance departments to protect personal and equipment safety. If the grounding wire is omitted on site or used improperly, it may cause a serious accident of closing the switch with the ground wire or personal injury. Preventing serious misoperation accidents of closing the switch with the ground wire and preventing unprotected accidents caused by poor contact of the ground wire are the main preventive measures for the use of grounding wires.

[0004] The existing grounding wire management adopts paper-based registration management, which has problems such as asynchronous information recording, difficult verification, and easy omissions. At the same time, there are many uncontrollable factors in the use of grounding wires, which will threaten the safe operation of personnel and equipment in serious cases. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a power plant grounding wire management system, which is used to manage the storage of grounding wires in power plants, especially the management of temporary grounding wires. The power plant grounding wire management system may include:

[0006] The information entry module is used to obtain the basic information of the managed grounding wire and update it in real time, and formulate the ID code of each grounding wire, and bind each grounding wire and the corresponding basic information to obtain the grounding wire label. The managed grounding wire is the grounding wire that is included in the management. Under normal circumstances, we will build a grounding wire storage cabinet at the corresponding location of the power station. The grounding wire storage cabinet needs to have a closed or semi-closed storage environment and meet the quantitative and fixed-position storage space. When storing, the grounding wire needs to be hung in a designated position for easy observation and retrieval. The grounding wire storage cabinet should be equipped with a temperature and humidity controller and a constant temperature and humidity device to ensure that the grounding wire storage meets the requirements. Therefore, the managed grounding wire includes the grounding wire stored in the storage cabinet and the grounding wire that has been taken out for use.

[0007] The calibration analysis module is used to obtain the current calibration time T and standard time T of each grounding wire according to the grounding wire label. 标 , and determine whether the current verification time T is less than the standard time T 标 If yes, no verification signal is sent, if no, a verification signal is sent and verification is performed. The grounding wire needs to be verified regularly. The current verification time T is the time from the last verification time or the use time of the grounding wire to the current time. The last verification time or the use time of the grounding wire can be obtained according to the verification record, the use record or the management account. The last verification time or the use time of the grounding wire here is the time point when the verification result is normal or the use record is normal. For those grounding wires with abnormal verification or use, manual re-inspection or elimination is performed.

[0008] The information acquisition module is used to obtain the current application information and determine whether the current application information is a return request. If yes, the return grounding wire label and its usage status are obtained. If the usage status is qualified, the corresponding storage position is unlocked. If it is unqualified, it is not unlocked, and a scrapping mark is sent to the grounding wire. If not, it is determined whether the current application information meets the usage requirements. If yes, the applicable grounding wire group is obtained according to the current application information, and the corresponding grounding wire label is obtained. If not, a reminder signal is sent.

[0009] The label push module is used to calculate the matching degree D of each grounding wire in the grounding wire group according to the grounding wire label of the grounding wire group and the current application use information, and use the grounding wire with the largest matching degree D as the grounding wire to be used, and unlock and display the grounding wire to be used.

[0010] The ledger statistics module is used to count the unlocked and returned grounding wires and their corresponding current application usage information, normalize the grounding wire labels with the same ID code, and generate a grounding wire management ledger. In the actual use process, the use and return of the grounding wire needs to be unlocked and locked at the corresponding position of the grounding wire. In this way, there will be the time points of the grounding wire's taking and returning and the corresponding current application usage information. If the ID code of the taken and returned grounding wires is the same, we will normalize the combination of this information in the grounding wire labels of the two.

[0011] Preferred: Standard duration T 标 It can be a fixed value or a value that changes according to the characteristics of the grounding wire. 标 When it is a variable value, its value can be set according to the characteristics of the grounding wire. The standard time for verification Where T′ is the length of time the grounding wire is in use. This value is the difference between the production date and the current time point, and its unit can be year, quarter or month. T″ is the verification node time, and its value can also be determined according to the service life of the grounding wire. ε is the verification standard coefficient. T0 is the verification standard time, and its value can be determined according to the specific situation. It is generally 1 month to 1 year. a is the performance base of the grounding wire. Its value is greater than 1 and is related to the frequency of use and duration of the same type of grounding wire. Generally, the longer the grounding wire is in use and the more frequently it is used, the smaller the value of the performance base a of the grounding wire will be, and vice versa. Its value is generally (1,5).

[0012] Preferably: the performance base of the grounding wire Where C is the average usage cycle of this type of grounding wire within a preset time period, which can be calculated by the ratio between the length of the preset time period and the number of times it is used. δ is the proportional adjustment coefficient.

[0013] Preferably, the check node time length T"=εA, wherein A is the standard service life of the grounding wire, which can be determined by the model of the grounding wire. Generally, a specific value is already set at the factory.

[0014] Preferably, sending a reminder signal may include: pushing whether to handle it urgently, if not, then ending the operation, if yes, then sending an authorization signal to the preset responsible staff, if the responsible staff remotely authorizes, then obtaining the appropriate grounding wire group according to the current application usage information, and obtaining its corresponding grounding wire label. If the responsible staff does not have remote authorization, then ending the current operation or allowing authorization and performing video recording.

[0015] Preferably: the degree of fit Where j is the number of the evaluation item, J is the total number of evaluation items, j = 1, 2, ..., J; E j 0 The usage value of the evaluation item numbered j can be obtained based on the current application usage information. The evaluation items may include: the length, specification, safety factor, etc. of the grounding wire. j is the actual value of the evaluation item numbered j, which can be obtained according to the grounding wire label. j is the correction factor of the evaluation item numbered j. Its value can be obtained by searching a pre-made item-correction information table based on the current application usage information. In actual use, the evaluation item usage value and the evaluation item actual value have real values ​​and substitute values. For example, the length of the grounding wire is the real value. The evaluation item usage value and the evaluation item actual value can be calculated based on the actual length of the grounding wire. In this case, the correction factor η j It can be set according to actual conditions. Its value is generally 0.1-10. The specific value is not described here.

[0016] The present invention also provides a method for managing a grounding line in a power plant, comprising:

[0027] The technical effects and advantages of the present invention: By using this method to manage the grounding wire, there is no need for manual recording, which can greatly reduce the recording time and avoid management dislocation. With the help of technologies such as the Internet of Things and wireless sensor networks, combined with the two-ticket three-system and relevant specifications for the use of grounding wires, the basic information, entry and exit of the warehouse, place of use, and on-site use (hanging status) of the grounding wire are managed in an all-round way.

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0033] Example 1

[0034] refer to Figure 1 In this embodiment, a power plant grounding wire management system is proposed, which is used to manage the storage of grounding wires in power plants, especially temporary grounding wires. The power plant grounding wire management system may include:

[0035] The information entry module is used to obtain the basic information of the management grounding wire and update it in real time, and formulate the ID code of each grounding wire, bind each grounding wire and the corresponding basic information to obtain the grounding wire label. The management grounding wire is the grounding wire included in the management. Under normal circumstances, we will build a grounding wire storage cabinet at the corresponding position of the power station. The grounding wire storage cabinet needs to have a closed or semi-closed storage environment and meet the quantitative and fixed-position storage space. When storing, the grounding wire needs to be hung in a designated position for easy observation and retrieval. The grounding wire storage cabinet should be equipped with a temperature and humidity controller and a constant temperature and humidity device to ensure that the grounding wire storage meets the requirements. Therefore, the management grounding wire includes the grounding wire stored in the storage cabinet and the grounding wire that has been taken out for use. In the storage cabinet, the grounding terminal and the grounding wire assembly constitute the grounding wire and are stored according to the storage location assigned by its ID code. The grounding wire needs to be combined when it is stored. The grounding terminal needs to be equipped with an intelligent grounding head with functions such as ID code identification, locking device, wireless communication, intelligent detection, and battery power supply. The structure of each functional equipment is not repeated here. When assembling the grounding wire and the grounding terminal in the grounding wire cabinet, the grounding terminal needs to perform ID code identification, unlock the grounding wire, and charge its battery; when the locking device is closed, the corresponding grounding wire cannot be taken. The basic information of the grounding wire may include the length, model, material, manufacturer, factory time, storage location, verification record, and usage record of the grounding wire. The usage record may also include the installation location, status, hooking operator, hooking ticket name, hooking ticket number, hooking time, etc. The content of the grounding wire label is relatively long, and it can be queried, counted, and saved in the form of a chart or information list. The length, model, material, manufacturer, and factory time of the grounding wire are immutable information, and these data will not change with the change of time. The verification record and usage record will change with the change of time. This information needs to be updated in time, so a time suffix can be added to the grounding wire label. The time suffix can be used to mark the data update time, which will not be described in detail here. When the grounding wire is not in use, the grounding wire and the grounding terminal are in a locked state, and the grounding wire cannot be used at this time.

[0036] The calibration analysis module is used to obtain the current calibration time T and standard time T of each grounding wire according to the grounding wire label. 标 , and determine whether the current verification time T is less than the standard time T 标If yes, then no verification signal is sent. If no, then a verification signal is sent and verification is performed. The grounding wire needs to be calibrated regularly. The current verification duration T is the time from the last verification time or usage time of the grounding wire to the current time. The last verification time or usage time of the grounding wire can be obtained based on the verification record, usage record or management ledger. The last verification time or usage time of the grounding wire here is the time point when the verification result is normal or the usage record is normal. For those grounding wires with abnormal verification or usage, manual re-inspection or elimination will be carried out. Standard duration T 标 It can be a fixed value or a value that changes according to the characteristics of the grounding wire. 标 When it is a fixed value, its value can be 1 month to 5 years, which can be determined according to the actual situation. In general, when manual verification is required, it is cumbersome, time-consuming and labor-intensive to verify it manually, and it is necessary to register it. In this case, the standard time length T 标 It cannot exceed 5 years. However, this application can automatically detect and receive the verification signal, and the standard verification time T 标 It can be greatly shortened, which not only reduces the workload, but also increases the inspection frequency, thus ensuring the safety of the grounding wire. 标 When it is a variable value, its value can be set according to the characteristics of the grounding wire. The standard time for verification Among them, T’ is the service life of the grounding wire, and this value is the difference between the production date time point and the current time point. Its unit can be years, quarters or months. T” is the verification node duration, and its value can be determined according to the actual situation. Generally, the value is 3 - 10 years. Details are not elaborated here. Its value can also be determined according to the service life of the grounding wire. Generally, T” = εA, where A is the standard service life of the grounding wire, which can be determined by the model of the grounding wire. Generally, specific values are available at the time of factory shipment. ε is the verification standard coefficient, and its value is generally 0.1 - 0.5. Details are not elaborated here. T0 is the verification standard duration, and its value can be determined according to the specific situation. Generally, it is 1 month - 1 year. a is the performance base number of the grounding wire, and its value is greater than 1 and is related to the usage frequency and service life of the same type of grounding wire. Generally, the longer the service life of the grounding wire and the greater the usage frequency, the smaller the value of the performance base number a of the grounding wire, and vice versa. Its value is generally (1, 5). Of course, other value settings are not excluded. Through this method of determination, it must be ensured that T’ < A, that is, the service life of the grounding wire is within the standard service life. When the service life of the grounding wire exceeds the standard service life, the grounding wire must be scrapped and recycled. Through this method, good verification and limitation of the grounding wire can be achieved. Within the verification node duration T”, the grounding wire is within the low-risk range. Since its factory inspection is qualified, the probability of failure during this period is almost zero. However, for the safe use of the equipment and according to relevant regulations, its verification frequency still cannot be less than the specified frequency. Therefore, during this period, its verification frequency only needs to meet the verification standard duration. However, when the service life T’ of the grounding wire exceeds the verification node duration T”, at this time, the service life T’ of the grounding wire will be restricted by both the verification node duration and the standard service life, so that the verification standard duration can vary within a certain range and will not be too large or too small. Generally, the verification node duration T” is much greater than the verification standard duration, that is, T’ / T0 should be greater than a, so as to ensure the upward trend of its value. For example, like the annual inspection of a car, details are not elaborated here. Ordinary verification stipulates a fixed frequency, but this cannot consider problems based on the actual situation of the grounding wire, resulting in frequent problems caused by the loss of the grounding wire or equipment aging during use. This method can fully change the development trend of equipment data by constructing a logarithmic limit. It can not only consider the equipment aging problem but also limit the development trend of numerical changes, and limit the verification standard duration from over-verifying with time. This calculation method uses T’ / T0 as the true number, which can fully reflect the relativity of the value, ensure that its value is greater than a, ensure the coherence of the data, and cannot change jumpily. The performance base number a of the grounding wire is related to the service life and usage frequency, and can fully consider the usage status of the grounding wire. This verification method can be more restricted based on the usage characteristics, frequency, and service life of the grounding wire, and can better control the organic limitation of the verification.For example, the standard service life a of a model of grounding wire is 20 years, and the verification standard coefficient ε is 0.3. We calculate the verification node duration T”=εA=0.3×20=6 years. The grounding wire is used for 8 years. 8 is greater than 6, which is the standard verification duration. At this time, the standard verification time T0 is 2, and the performance base a of the grounding wire is 2, so the standard verification time is As the usage time increases, the standard test duration will form a gentle slope reduction, which will not lead to a sharp increase in the detection frequency due to excessive reduction, and can well adapt to the aging and frequency development trend of the grounding wire. The performance base a of the grounding wire can also be obtained by calculation. Where C is the average usage cycle of this type of grounding wire within a preset time period, which can be calculated by the ratio between the length of the preset time period and the number of times used. δ is the proportional adjustment coefficient, and its value is generally 5-100, which depends on the actual situation and will not be described in detail here.

[0037] The information acquisition module is used to obtain the current application information and determine whether the current application information is a return request. If yes, the return grounding wire label and its usage status are obtained. If the usage status is qualified, the corresponding storage position is unlocked. If it is not qualified, it is not unlocked, and the grounding wire is sent a scrapping mark. If not, it is determined whether the current application information meets the usage requirements. If yes, the applicable grounding wire group is obtained according to the current application information, and the corresponding grounding wire label is obtained. If not, a reminder signal is sent. When we are doing electrical work, we need to apply for the use of grounding wires in advance according to the operation requirements. It is necessary to apply through two tickets. The application information can be entered manually or through the display screen of the host equipped on the cabinet. Manual entry can be done by the operator entering the operator's information, two ticket information, required grounding wire specifications, etc. The host can be equipped with a code scanning or other identification device, and can directly scan the code, fingerprint, facial recognition, etc. for identity authentication. Among them, the code scanning acquisition includes two ticket information entry, work permit recognition, etc., and facial recognition is for operator verification, etc., which will not be repeated here. The specifications of the grounding wire are entered through the host display screen equipped on the cabinet. In general, as long as the two tickets are available, the work permit is normal and the operator is a professional, the use requirements are met. If the two tickets are incomplete, the work permit is incorrect or the operator is not a professional, it is deemed that the use requirements are not met. Of course, this is only a general situation. Other situations can also be limited by the time period of use, grounding wire specifications, etc., which are not described in detail here. The grounding wire group is all grounding wires that meet the current application usage information and are stored. In general, in order to avoid the borrowing or damage of the grounding wire, at least two grounding wires of the same specification need to be set. Of course, the possibility of one is not excluded. There may be many specifications that meet the use requirements, but there is only one specification that is most suitable. At this time, the applicable grounding wire group will include multiple grounding wires. We put all the grounding wires that meet the use requirements together to form a grounding wire group. Reference Figure 2 , sending a reminder signal can display the current application use information that does not meet the use requirements through the host, for example, two tickets are incomplete, the work permit is incorrect, the current specification grounding wire is not stored, etc., which are not listed here one by one, so as to remind the operator to deal with it in a targeted manner. Of course, in order to facilitate the emergency use of the grounding wire, it can also remind whether to deal with it urgently, and display a dialog box and "yes" and "no" options through the host, allowing the operator to choose by himself. If no, the operation is terminated. If yes, an authorization signal can be sent to the preset responsible staff, and the authorization is performed by the responsible staff. If the responsible staff remotely authorizes, it can execute the acquisition of the appropriate grounding wire group according to the current application use information, and obtain its corresponding grounding wire label. If the remote authorization is not passed, the current operation is terminated or allowed to pass and recorded. Sending a signal to the preset responsible staff can be by sending an authorization code or directly remotely controlling the authority, which is not repeated here.

[0038] The label push module is used to calculate the degree of fit D of each grounding wire in the grounding wire group according to the grounding wire label of the grounding wire group and the current application information, and use the grounding wire with the largest degree of fit D as the grounding wire to be used, and unlock and display the grounding wire to be used. The label push module can also be responsible for controlling the temperature and humidity of the grounding storage cabinet, providing the current status of the grounding wire, executing the issued unlocking / locking commands, etc. The specific execution method will not be repeated here. As mentioned above, there are multiple grounding wires in the grounding wire group. If there is only one, this grounding wire is the grounding wire to be used. If there are multiple grounding wires, we need to evaluate them. Of course, you can also directly choose one to recommend as the grounding wire to be used. The details will not be repeated here. The degree of fit Where j is the number of the evaluation item, J is the total number of evaluation items, j = 1, 2, ..., J; E j 0 The usage value of the evaluation item numbered j can be obtained based on the current application usage information. The evaluation items may include: the length, specification, safety factor, etc. of the grounding wire. j is the actual value of the evaluation item numbered j, which can be obtained according to the grounding wire label. j is the correction factor of the evaluation item numbered j. Its value can be obtained by searching a pre-made item-correction information table based on the current application usage information. In actual use, the evaluation item usage value and the evaluation item actual value have real values ​​and substitute values. For example, the length of the grounding wire is the real value. The evaluation item usage value and the evaluation item actual value can be calculated based on the actual length of the grounding wire. In this case, the correction factor η j It can be set according to the actual situation, and its value is generally 0.1-10. The specific value is not repeated here. There is no specific value for the specifications and safety factor of the grounding wire. The specific evaluation item usage value and the actual value of the evaluation item can be obtained according to the pre-made information table. For example, we can edit the corresponding evaluation item usage value and the actual value of the evaluation item for the grounding wire of each specification in advance. We edit the values ​​of the grounding wires corresponding to each specification. The specific content is not the subject of protection of this application and will not be repeated here. Then the correction coefficient η j The value can be 1. The safety factor can be obtained based on the calibration time point data, and can be determined based on the value deviation. The larger the current calibration time T, the smaller the safety factor. The specific value can be obtained based on the time-safety factor value information mark. For example, we calibrate the safety factor of 6 months as 1 and the safety factor of 1 year as 0.5. At this time, the correction factor η jThe value can also be 1. The specific settings of other values ​​are not described here. Each grounding wire is connected to a corresponding locking device. When the locking device is closed, the grounding wire can be saved and the grounding wire cannot be taken out. When the locking device is unlocked, the grounding wire can be taken out and the grounding wire to be used is displayed. The storage position can be displayed on the main display screen, and a display light can be installed at the storage position of each grounding wire. When the corresponding grounding wire is unlocked, the display light will light up for display, so that the operator can take it in a targeted manner without having to manually search for the storage position, avoiding the subjectivity of human evaluation and taking errors, and better managing the grounding wire.

[0039] The ledger statistics module is used to count the unlocked and returned grounding wires and their corresponding current application usage information, normalize the grounding wire labels with the same ID code, and generate a grounding wire management ledger. In the actual use process, the use and return of the grounding wire needs to be unlocked and locked at the corresponding position of the grounding wire, so that there will be the time points of the grounding wire's taking and returning and the corresponding current application usage information. If the ID codes of the taken and returned grounding wires are the same, we will normalize the combination of this information in the grounding wire labels of the two. For example, when taking, the grounding wire label has an ID code - length, model, material, manufacturer, factory time, storage location, verification record, historical use record, borrowing time, etc. When returning, the grounding wire label has a grounding wire ID code - use location, use status and return time, etc. If the ID codes of the two grounding wire labels are the same, a management ledger can be generated, ID code - length, model, material, manufacturer, factory time, storage location, verification record, historical use record, borrowing time, use location, use status and return time, etc. Of course, this is just a simple example and is not necessarily universal. Other specific situations will not be described here. By using this method to manage the grounding wire, there is no need for manual recording, which can greatly reduce the recording time and avoid management dislocation.
