[0021] The drawings described herein are used to provide a further understanding of the present disclosure and constitute a part of the present disclosure. The illustrative embodiments of the present disclosure and their descriptions are used to explain the present disclosure and do not constitute an improper limitation on the present disclosure. In the drawings:

[0022] Figure 1 is a flow chart of a method for processing power grid accident tripping according to one embodiment of the present disclosure;

[0023] Figure 2 It is a structural block diagram of a power grid accident tripping processing device according to one embodiment of the present disclosure. DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the scheme of the present disclosure, the technical scheme in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present disclosure.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0026] The power grid accident tripping processing method in the related technology usually relies on the professional knowledge and field experience of the operating personnel to achieve a rapid response and processing of the tripping accident. However, this method has the problem of high subjectivity and arbitrariness in the processing process. In the context of a wide variety of equipment and complex fault types, relying solely on personal skills and experience is often not enough to deal with all situations, thereby reducing the overall efficiency and reliability of power grid accident processing.

[0027] Specifically, in actual applications, the power grid accident tripping processing method in the related art may result in misjudgment or omissions in the process of handling tripping accidents due to the different levels of understanding of the characteristics of different equipment by operators and the differences in the accuracy of fault type identification. For example, when faced with a specific type of tripping fault, operators may only check based on past experience, but fail to consider that the fault may be caused by multiple factors or present different characteristics under specific circumstances, which will result in incomplete fault handling or even wrong decisions. In addition, when a tripping accident occurs at night or under severe weather conditions, the operator's visual judgment ability is limited, which further exacerbates the uncertainty in the handling process.

[0028] Furthermore, due to the diversity and complexity of power grid equipment, operators often need to collect a large amount of information in a short period of time when dealing with tripping accidents, including but not limited to the voltage level, dual name, location, protection device configuration, etc. of the equipment, as well as the specific conditions and environmental factors at the time of tripping. In high-voltage and emergency situations, relying solely on personal skills and experience for data integration and analysis often affects the rapid location and handling of faults due to untimely or inaccurate information processing, thereby reducing the overall efficiency of power grid accident handling, prolonging the time for the power system to resume normal operation, and increasing the risks and costs of power grid operation.

[0029] According to an embodiment of the present disclosure, a method embodiment of a method for handling power grid accident tripping is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] The memory can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the power grid accident tripping processing method in the embodiment of the present disclosure. The processor executes various functional applications and data processing by running the computer program stored in the memory, that is, the above-mentioned power grid accident tripping processing method is realized. The memory may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory may further include a memory remotely arranged relative to the processor, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0032] The transmission device is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0033] The display device may be, for example, a touch screen type liquid crystal display (LCD) and a touch display (also referred to as a "touch screen" or "touch display screen"). The liquid crystal display may enable a user to interact with a user interface of a mobile terminal. In some embodiments, the mobile terminal has a graphical user interface (GUI), and a user may interact with the GUI by finger contacts and / or gestures on a touch-sensitive surface, wherein the human-computer interaction functions here may optionally include the following interactions: creating web pages, drawing, word processing, making electronic documents, games, video conferencing, instant messaging, sending and receiving emails, call interfaces, playing digital videos, playing digital music and / or web browsing, etc. The executable instructions for executing the above human-computer interaction functions are configured / stored in a computer program product or readable storage medium executable by one or more processors. Figure 1 is a flow chart of a method for processing a power grid accident tripping according to one embodiment of the present disclosure, such as Figure 1 As shown, the method comprises the following steps:

[0034] Step S11, constructing a database according to the substation data, wherein the database includes an equipment database, an accident tripping logic database, and a guidance template database;

[0035] Step S12, obtaining tripping device data;

[0036] Step S13, outputting fault handling guidance data according to the tripping device data and the database, wherein the fault handling guidance data is used to guide the fault handling personnel to handle the accident tripping fault.

[0037] The above-mentioned substation data refers to a collection of detailed information related to the operation, management, monitoring and maintenance of power grid substations, including but not limited to basic equipment information, real-time operation data, protection device configuration and action data, electrical wiring diagrams, environmental and meteorological data, historical fault and maintenance records, safety regulations and operating manuals, preset industry accident handling standards, etc. Among them, basic equipment information includes but is not limited to the dual name of the equipment, type, voltage level, manufacturer, factory date, installation location, electrical equipment data, normal range of pressure gauge, etc.

[0038] The above-mentioned tripping device data refers to the device status and operation information directly related to the specific tripping event when the power grid accident tripping occurs. Specifically, the tripping device data includes but is not limited to the tripping time, device identification information, operating status data before and after the tripping, the nature of the tripping event, etc. Among them, the nature of the tripping event includes instantaneous tripping or permanent tripping. Instantaneous tripping refers to the automatic tripping of power grid equipment after encountering an instantaneous fault or abnormality, but after the fault is eliminated, the equipment or line can quickly return to normal operation without additional repair or replacement work. It is usually caused by lightning strikes, instantaneous short circuits caused by contact with objects such as branches, insulator flashovers caused by changes in atmospheric conditions, arc shocks generated when operating disconnectors, or equipment overloads. Permanent tripping refers to the equipment or line. After the trip, even if the fault source has been eliminated, it still cannot return to normal operation, and requires maintenance or replacement of parts to resume service. It is usually caused by equipment damage, line failure, external force damage, etc.

[0039] Exemplarily, during the operation of the substation, the substation data is continuously collected through sensors and monitoring devices installed on the equipment, and a comprehensive substation data database including an equipment database, an accident tripping logic database, and a guidance template database is constructed based on the substation data. Furthermore, the above-obtained database is saved to the smart grid accident tripping processing assistant APP. When a tripping accident occurs, the smart grid accident tripping processing assistant APP receives the tripping device data obtained by the substation monitoring system, and based on the tripping device data and the information in the equipment database, the accident tripping logic database, and the guidance template database, intelligently analyzes the cause of the tripping, and generates specific fault handling guidance data, including inspection steps, disposal suggestions, safety regulations, and reporting templates, etc., to help on-site personnel respond to and handle accident tripping quickly and accurately, reduce power grid interruption time, and improve safety and efficiency.

[0040] Based on the above steps S11 to S13, according to the substation data, a comprehensive database including an equipment database, an accident tripping logic database and a guidance template database is constructed, and then when a tripping fault occurs, the fault handling guidance data is output according to the tripping equipment data and the comprehensive database, thereby achieving the purpose of providing comprehensive and standardized guidance for power grid accident tripping processing, thereby achieving the technical effect of improving the accuracy and efficiency of fault processing and reducing human errors, and thus solving the technical problems of excessive reliance on personnel skills and experience, and high subjectivity and arbitrariness in the processing process of the power grid accident tripping processing method provided in the relevant technology.

[0041] Optionally, in step S11, a device database is constructed according to the substation data, including: constructing a device database according to the device voltage level, dual name, device location, normal operating condition of the device and protection device configuration contained in the substation data.

[0042] The above equipment voltage level refers to the voltage level that the power equipment can withstand or operate during design and operation, which is directly related to the insulation requirements, electrical clearance size, current carrying capacity of the equipment and the selection of related control and protection equipment. Specifically, the equipment voltage level includes low voltage, medium voltage, high voltage, extra high voltage or ultra high voltage. The equipment voltage level is shown in Table 1:

[0043] Table 1 Equipment voltage level

[0044]

[0045] In Table 1, low-voltage equipment generally refers to equipment with a voltage level below 1kV, such as distribution equipment for household or industrial electricity, lighting equipment, etc.; medium-voltage equipment generally refers to equipment with a voltage level between 1kV and 35kV, which is suitable for medium-sized industrial or commercial buildings, power distribution networks, etc.; high-voltage equipment generally refers to equipment with a voltage level between 35kV and 220kV, which is widely used in long-distance power transmission and large substations; ultra-high voltage or UHV equipment generally refers to equipment with a voltage level exceeding 220kV, which is mainly used for long-distance, large-capacity power transmission.

[0046] The above dual name refers to the naming method that combines the device name and number to ensure the uniqueness and clarity of the device identification. The dual name usually includes the type name or functional description of the device and a unique number or letter number to accurately identify each device in the power system.

[0047] For example, "#1 main transformer" means the first main transformer in the substation, where "#1" is the equipment number and "main transformer" is the type name of the equipment; "110kV#2 circuit breaker" means the second circuit breaker with a voltage level of 110kV, where "#2" is the equipment number, "circuit breaker" is the equipment type, and "110kV" means the voltage level; "35kV#A voltage transformer" means a voltage transformer with a voltage level of 35kV, where "#A" is the equipment number and "voltage transformer" is the type of equipment.

[0048] The above-mentioned normal working conditions of the equipment are the standard working conditions preset for each electrical equipment. Taking the normal range of the pressure gauge as an example, the normal range of the pressure gauge refers to the expected range of pressure values ​​displayed by the pressure gauge equipped in the power equipment under normal operating conditions of the equipment. In power equipment, the pressure gauge is usually used to monitor the gas pressure, oil pressure or cooling medium pressure value inside the equipment. The above-mentioned pressure values ​​are crucial to ensure the normal operation and safety of the equipment.

[0049] For example, in the Smart Grid Accident Tripping Handling Assistant APP, the device database stores the normal operating parameters of the equipment, including the normal range of the pressure gauge. When a tripping accident occurs, the APP can call this information and compare it with the pressure readings collected on site to help fault handling personnel quickly determine whether the pressure abnormality is one of the causes of the tripping event, and provide corresponding processing guidance accordingly to ensure that the inspection and recovery operations of the equipment meet safety standards and industry specifications, and reduce the risk of secondary accidents caused by pressure problems.

[0050] The above protection device configuration refers to the detailed settings and functional specifications of the protection device set in the power system to ensure equipment safety and grid stability. Specifically, the protection device configuration includes but is not limited to protection type, protection setting, action logic, communication interface, self-test and maintenance settings, among which the protection type includes but is not limited to overcurrent protection, overvoltage protection, distance protection, etc.; the protection setting is the trigger condition for the protection device to start, such as the current or voltage threshold; the action logic indicates whether the protection device is started and how to start the protection action.

[0051] Exemplarily, first, the equipment database structure is designed to determine the equipment information fields that need to be stored, such as equipment ID, voltage level, dual name, equipment location, normal range of pressure gauge, etc. Further, detailed information of the equipment is collected from sources such as substation operation records, equipment technical manuals, and monitoring systems, and the collected information is entered into the equipment database.

[0052] For example, a device record entry in the device database is as follows:

[0053] 1) Device ID: 001;

[0054] 2) Voltage level: 110kV;

[0055] 3) Dual designation: #3 Main Transformer;

[0056] 4) Equipment location: Substation A, transformer area, location 2;

[0057] 5) Normal range of pressure gauge: oil pressure: 0.15MPa-0.3MPa; gas pressure: 0.6MPa (20℃);

[0058] 6) Protection device configuration:

[0059] a) Protection type: overcurrent protection;

[0060] b) Protection setting: Overcurrent protection: 1.5 times rated current;

[0061] c) Action logic: After the overcurrent protection is triggered, if the differential protection does not operate within 500ms, the backup protection will be activated;

[0062] d) Communication interface: using IEC 61850 standard communication protocol to connect with the substation monitoring system;

[0063] e) Self-check and maintenance settings: automatically check the protection settings once a month and conduct a comprehensive maintenance check once a year.

[0064] Based on the above optional embodiments, an equipment database is constructed according to the equipment voltage level, dual name, equipment location, normal range of pressure gauge and protection device configuration contained in the substation data. When an accident trip occurs, the fault handling personnel can quickly retrieve all relevant information of the equipment in the database through the dual name or ID of the equipment, thereby quickly locating the faulty equipment and improving the response speed.

[0065] Optionally, in step S11, an accident tripping logic database is constructed according to substation data, including:

[0066] Step S1111, determining multiple fault types corresponding to the electrical equipment according to the electrical equipment data, wherein the electrical equipment data is included in the substation data;

[0067] Step S1112, determining multiple protection strategies according to the multiple fault types, wherein the multiple protection strategies correspond to the multiple fault types one by one;

[0068] Step S1113, constructing an accident tripping logic database according to the correspondence between the electrical equipment, multiple fault types and multiple protection strategies.

[0069] The above-mentioned electrical equipment includes but is not limited to transformers, circuit breakers, lines, etc. Among them, the corresponding fault types of transformers include: winding short circuit, abnormal transformer oil level, excessive oil temperature, insulation damage, etc.; the corresponding fault types of circuit breakers include: operating mechanism failure, contact wear, control circuit abnormality, insufficient gas pressure, etc.; the corresponding fault types of lines include: single-phase grounding, two-phase short circuit, three-phase short circuit, insulator flashover, etc.

[0070] For example, for transformer winding short circuit, differential protection and overcurrent protection can be set; for circuit breaker operating mechanism failure, mechanical locking device and auxiliary contact monitoring can be set; for line ground short circuit, zero-sequence current protection and distance protection can be configured.

[0071] Furthermore, the corresponding relationships among electrical equipment, fault types and protection strategies are summarized and organized to construct an accident trip logic database. When a trip event occurs, the trip device and possible fault type can be quickly identified by querying the accident trip logic database.

[0072] Based on the above optional embodiments, an accident tripping logic database is constructed according to the correspondence between electrical equipment, multiple fault types and multiple protection strategies, which can provide intelligent support for the smart grid accident tripping processing assistant APP for rapid fault identification, dynamic matching of protection strategies and standardized processing procedures, thereby improving the fault response capability and operation and maintenance efficiency of the power system.

[0073] Optionally, in step S11, a guidance template database is constructed according to the substation data, including:

[0074] Step S1121, constructing a standardized accident handling process for various accidents of electrical equipment according to preset industry accident handling standards, wherein the preset industry accident handling standards are included in the substation data;

[0075] Step S1122, constructing a guidance template database based on the correspondence between electrical equipment and standardized accident handling procedures.

[0076] The above-mentioned preset industry accident handling standards refer to the procedures and guidelines formulated within the power industry to guide the handling of electrical equipment accidents, ensure the safe operation of the power system, reduce the losses caused by accidents, and protect the personal safety of operators. Specifically, the preset industry accident handling standards include but are not limited to accident response procedures, personnel safety regulations, fault location and isolation, fault handling and repair processes, equipment reset and system recovery, accident prevention and equipment maintenance, and communication and coordination in emergency situations.

[0077] The accident response procedure refers to the measures that should be taken at the first time when an accident occurs, such as immediately stopping all operations that may aggravate the accident, activating the emergency response system, reporting the accident to superiors, etc.; Personnel safety regulations refer to the personal safety rules during the accident handling process, including the use of personal protective equipment, following electrical safety operating procedures, ensuring the safe isolation of the accident area, etc.; Fault location and isolation are used to guide how to quickly locate the source of the fault and safely isolate the faulty equipment to prevent the fault from spreading and protect the unaffected part of the power grid; Fault handling and repair process provides detailed fault handling steps, including temporary repair measures, equipment inspection checklists, power restoration procedures, etc., to ensure that the fault is handled promptly and correctly; Equipment reset and system recovery are used to indicate how to safely reset the equipment and restart the affected system after the fault handling is completed to restore the normal operation of the power grid; Accident prevention and equipment maintenance refers to the formulation of accident prevention measures and equipment maintenance plans based on previous accident cases to reduce the possibility of future accidents; Communication and coordination in emergency situations refers to the communication channels and coordination mechanisms established during the emergency to ensure that all relevant parties can communicate and collaborate quickly and effectively.

[0078] For example, taking the overheating tripping accident of the main transformer of a 110kV substation as an example, when an overheating trip occurs, the operator inputs the tripping device manually or by voice, and obtains the equipment status data at the time of tripping, such as temperature, pressure, current, etc., through the substation monitoring system. At the same time, the emergency response system is started to notify the duty personnel and the superior dispatching center, report the preliminary situation of the accident, and suspend operations unrelated to the accident handling to avoid interference and the expansion of the accident. Further, during the on-site fault location and isolation process, all operators must wear qualified personal protective equipment to ensure that the operators are away from the faulty equipment until the safety is evaluated and confirmed, and implement electrical isolation, disconnect all power supplies related to the faulty transformer, and hang up a warning sign. Subsequently, an infrared thermal imager is used to check the surface temperature distribution of the transformer, find the overheating area, check whether the cooling system is operating normally, including fans, oil pumps, etc., and analyze the operating data before the trip to determine whether the cause of overheating is an internal fault or an external overload. According to the cause of overheating, temporary repair measures are taken, such as adding cooling medium, adjusting the load, etc., checking the oil level and oil quality of the transformer, and replacing or filtering if necessary. After completing the initial repair, check the equipment status again to ensure that the overheating problem has been resolved. After confirming that the equipment is safe, restart the cooling system and transformer according to the preset reset procedure. According to the power restoration procedure, gradually restore the affected grid area and monitor the equipment operation status. After completing the system restoration, carry out subsequent equipment maintenance inspections to ensure the long-term stable operation of the equipment.

[0079] Furthermore, based on the above tripping accident handling process, a guidance template can be created for the 110kV main transformer overheating accident, including the following contents:

[0080] 1) Title: Handling of overheating accident of 110kV main transformer;

[0081] 2) Guidance report number: TBGH-110-001;

[0082] 3) Version: 1.0;

[0083] 4)Processing flow.

[0084] In addition, the guidance template database also includes other types of tripping accident handling processes, such as circuit breaker operating mechanism failure, line grounding short circuit, etc., which will not be elaborated here.

[0085] Based on the above optional embodiments, a guidance template database is constructed according to the correspondence between electrical equipment and standardized accident handling procedures, which not only provides immediate guidance for on-site accident handling, but also provides rich resources for operator training and learning, which helps to improve the ability of the entire power system to respond to emergencies.

[0086] Optionally, in step S13, fault handling guidance data is output according to the tripping device data and the database, including:

[0087] Step S131, determining basic equipment data corresponding to the tripping equipment according to the tripping equipment data and the equipment database;

[0088] Step S132, determining the type of tripping accident according to the tripping device data, the basic equipment data and the accident tripping logic database;

[0089] Step S133, determining fault handling guidance data according to the tripping device data, the tripping accident type and the guidance template database.

[0090] For example, when a tripping accident occurs, it is first necessary to parse the received tripping device data, namely the device ID, tripping time, electrical parameters at the time of tripping (such as current, voltage, power, etc.) and possible alarm information. Then, use the device ID as an index to query the device database and obtain the basic device data of the device. Furthermore, the tripping device data, the basic device data and the logic rules in the accident tripping logic database are matched, and the specific type of the tripping accident is determined by analyzing the changes in electrical parameters at the time of tripping, protection action information, and the historical operating status of the equipment. Once the type of tripping accident is determined, the processing flow and safety operation guide that match the accident type can be retrieved from the guidance template database in the smart grid accident tripping processing assistant APP.

[0091] Based on the above optional embodiments, fault handling guidance data is determined according to the tripping accident and guidance template database, which can provide operators with immediate, accurate and safe operation guidance, ensure the standardization and regularization of accident handling, and at the same time reduce the difficulty of decision-making through intelligent analysis, improve the efficiency and effectiveness of accident handling, thereby ensuring the safe and stable operation of the power system.

[0092] Optionally, the power grid accident tripping processing method further includes:

[0093] Step S21, acquiring fault processing data, wherein the fault processing data is used to characterize the equipment status obtained by the fault handling personnel in inspecting and processing the accident tripping fault;
