Description

Technical Field

[0001] The present invention belongs to the technical field of power equipment operation and maintenance, and specifically relates to a distributed energy monitoring system and method driven by the Internet of Things. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] For power supply operators, electricity users lack experience in maintaining their own power equipment. Therefore, power supply operators maintain power equipment / facilities on behalf of customers. However, due to the diverse needs of different electricity users, such as differences in industry attributes and differences in the capacity and scale of power equipment, the performance of equipment used for power supply varies greatly, making it difficult for power supply operators to grasp the status of power equipment and power demand of different customers, and thus difficult to meet the maintenance needs of different customers for power equipment.

[0004] Since there are correlations between various power equipment, the cause of the fault alarm on a certain device may not be a problem with the current device, but a problem with another related device. It is necessary to assist maintenance engineers to determine the source of the fault based on factors such as equipment correlation and electrical quantity data, accurately lock the root cause of the fault, and quickly solve the alarm problem. In the power system, the fuses of the main distribution line (bus) and branch circuits (branch lines) are usually fast-acting fuses. These fuses are extremely sensitive to current overloads. Once the current exceeds its rated value, it will quickly disconnect the circuit to prevent serious consequences such as equipment damage or fire. This fast response feature ensures that the main distribution system can immediately isolate the fault point when facing a short circuit or severe overload. In contrast, branch circuit fuses are more likely to use thermal fuses. The working principle of this type of fuse is based on the heat generated when the current passes through. When the current exceeds the rated value, the material inside the fuse will gradually heat up until it reaches the melting point and melts. Since this process involves the accumulation and conduction of heat, the action time of the thermal fuse will be delayed relative to the fast-acting fuse. This delay may cause the fuse to fail to blow immediately when the initial fault current rises in the branch circuit, allowing the fault current to persist. When the fault current in the branch circuit persists for a certain period of time and is not controlled in time, it may affect the main distribution line through the interconnectivity of the power grid, causing the current in the main distribution line to increase accordingly. If the current in the main distribution line exceeds the rating of its fuse (fast-acting fuse), the fuse in the main distribution line will blow quickly to protect the entire power system from more serious damage. Therefore, the actual reason for the main distribution line to blow due to excessive current can be attributed to the branch circuit current being too high and not being blown by the thermal fuse in time, which in turn causes the main distribution line to overload and trigger the chain reaction of the fast-acting fuse blowing. There is a significant difference in the fusing mechanism, which has an important impact on fault location and response speed.

[0005] However, in the existing power equipment operation and maintenance system, fault monitoring often ignores the correlation between various power equipment, and the significant differences in the fuse blowing mechanisms of the main distribution lines and branch lines are not accurately monitored, resulting in inaccurate fault location, which causes deviations in the generation of subsequent operation and maintenance work orders, reducing operation and maintenance efficiency and accuracy. Summary of the invention

[0006] In order to solve the above problems, the present invention proposes a distributed energy monitoring system and method driven by the Internet of Things. The present invention utilizes the association relationship between various power equipment to quickly locate faulty equipment so as to accurately issue operation and maintenance work orders; and constructs an operation and maintenance service platform for electricity users through the Internet of Things layer, application layer and service layer to meet the diversified power equipment maintenance needs of electricity users due to differences in industry attributes and capacity scale.

[0007] According to some embodiments, a first solution of the present invention provides a distributed energy monitoring system driven by the Internet of Things, which adopts the following technical solutions:

[0008] A distributed energy monitoring system driven by the Internet of Things includes a server end and a plurality of inspection information entry terminals; the server includes an application layer, a service layer, an Internet of Things layer and a station control layer;

[0009] The station control layer is used to control the operation of the monitoring video equipment and the energy monitoring terminal, and transmit the operation results to the Internet of Things layer;

[0010] The Internet of Things layer is used to provide the application layer with the service of the operating status of the power equipment, and is responsible for realizing the equipment energy consumption monitoring and generating data reports;

[0011] The application layer includes an energy efficiency management module and a video monitoring module; wherein the energy efficiency management module constructs a corresponding topological structure according to the power lines provided by the Internet of Things layer, configures line association relationships, and sets alarm rules; when abnormal data that meets the alarm rules is monitored, it performs association analysis based on the line association relationships, compares the data changes of each monitoring point, and determines the location of the fault;

[0012] The service layer is used to generate a corresponding operation and maintenance work order according to the fault monitoring result of the application layer and send it to the corresponding inspection information entry terminal.

[0013] Furthermore, the service layer is used to create customer information files, equipment files and operation and maintenance contract files, and is responsible for coordinating the closed-loop process of "creating customer information → creating operation and maintenance equipment files → creating delegated equipment operation and maintenance contracts → delegating operation and maintenance staff → operation and maintenance staff performing work → feedback on equipment operation and maintenance results" between the equipment manufacturer and the equipment operation and maintenance party;

[0014] The service layer is connected to the application layer and has a memory for storing power equipment information, power equipment user information and operation and maintenance contract information.

[0015] Furthermore, the service layer mainly includes three parts: system management module, on-site handover management module, and operation and maintenance management module;

[0016] The functions at this level mainly include file management, maintenance contracts, handover and dispatch, handover reports, inspection plans, maintenance dispatch, operation and maintenance files, and the formation of data reports.

[0017] Furthermore, the system management module includes a file management unit, the on-site handover management module includes a maintenance contract unit, a handover dispatch unit, and a monitoring terminal interface configuration unit, and the operation and maintenance operation management module includes an inspection plan unit and a maintenance dispatch unit;

[0018] The file management unit is used for customer file management, maintenance facility file management, and monitoring point file management;

[0019] The on-site handover management module is used to configure the equipment monitoring point interface, draft equipment maintenance contracts based on the equipment type and maintenance work mode that the customer needs to maintain, and then hand over the equipment operation and maintenance work to the equipment maintenance party;

[0020] The operation and maintenance management module is a service module for the equipment maintenance entrustee to formulate inspection plans and assign repair workers.

[0021] Furthermore, the application layer is used to provide instantaneous quantity, electric energy, demand, environmental parameters, upper oil temperature of the equipment, and data analysis services of the power equipment, and provide basic query and monitoring function services for the service layer;

[0022] The energy efficiency management module includes five functional modules: online monitoring, power consumption overview, maximum demand, real-time power statistics and energy efficiency report. The video surveillance management module includes two functional modules: real-time monitoring and video playback.

[0023] Furthermore, the system also includes a storage layer, and the storage layer is used for data storage.

[0024] Furthermore, the Internet of Things layer is composed of a switching power supply, a data sensor, a data transmission port, a CPU, a storage chip, a wireless communication module, a device monitoring terminal and an Internet of Things management terminal;

[0025] Collect power equipment operating parameters and environmental parameters through data sensors and equipment monitoring terminals, and then connect to the Internet of Things management terminal through the data transmission port to transmit data;

[0026] After the CPU is powered on, it starts to boot and calls the built-in system in the memory chip. The CPU will intermittently call the built-in system according to the parameters set by the real-time clock.

[0027] After the built-in system is called, the CPU will obtain the data transmitted by the device monitoring terminal and the data sensor and write the data into the storage chip. Finally, the obtained data will be transmitted to the application layer through the wireless communication module.

[0028] According to some embodiments, a second solution of the present invention provides an IoT-driven distributed energy monitoring method, which adopts the following technical solution:

[0029] An IoT-driven distributed energy monitoring method, based on an IoT-driven distributed energy monitoring system as described in the first solution, comprises:

[0030] Use the positioning function of the inspection information input terminal device to match the latitude and longitude of the power equipment site in the operation and maintenance contract, so as to obtain the punch-in information of the maintenance personnel at a fixed time and point at the work site;

[0031] At the beginning of the contract period, the maintenance personnel will conduct regular inspections on the power equipment according to the inspection cycle agreed in the contract. After the inspection, the customer's power equipment ledger for inspection and maintenance will be entered into the system and the inspection plan will be executed in the service layer. During the execution, the work records of the maintenance equipment will be entered into the service layer, and the maintenance records of the faulty equipment will be reflected in the operation and maintenance files. The above work will eventually generate operation and maintenance reports regularly in the application layer.

[0032] During the inspection process, the corresponding topological structure is constructed according to the power lines, the line association relationship is configured, and the alarm rules are set; when abnormal data that meets the alarm rules is monitored, correlation analysis is performed based on the line association relationship, and the data changes of each monitoring point are compared to determine the location of the fault.

[0033] Furthermore, the corresponding topological structure is constructed according to the power lines, the line association relationship is configured, and the alarm rules are set, specifically:

[0034] Establish a corresponding topological structure according to the power line, including the bus, branch lines and their connection relationships;

[0035] According to the actual situation of the power system, configure the total-score relationship between the line corresponding to a specific monitoring point and the lines corresponding to other monitoring points;

[0036] According to the operation specifications and experience data of the power system, set the alarm thresholds corresponding to various power operation data for each monitoring point;

[0037] Configure alarm conditions based on alarm thresholds.

[0038] Furthermore, when abnormal data that meets the alarm rules is monitored, correlation analysis is performed based on the line association relationship, and the data changes of each monitoring point are compared to determine the location of the fault, specifically:

[0039] When the power operation data of the power equipment is monitored to be greater than the corresponding alarm threshold, it is determined whether the equipment has a lower-level device. If so, it is determined whether the lower-level device has an alarm; otherwise, it is determined that the equipment has exceeded the limit and an alarm has been issued;

[0040] If the lower-level device alarms, determine whether the operation data of the lower-level device is consistent with that of the current device alarm. If so, determine whether the same operation data of the lower-level device and the current device alarm is greater than the alarm threshold; otherwise, determine that the current device operation data alarms while the lower-level device does not have the same operation data alarm;

[0041] If the same operating data of the lower-level device and the current device is greater than the alarm threshold, the same operating data of the current device and the lower-level device will simultaneously exceed the upper limit alarm, and the correlation relationship will be displayed; otherwise, the same operating data of the current device and the lower-level device will alarm at the same time, but the lower-level device will alarm when the data is lower than the alarm threshold.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] When the system detects data that meets the alarm conditions, the present invention immediately triggers an alarm and notifies relevant personnel through text messages, emails, etc. The alarm information is correlated and judged according to the configured association relationship. By comparing the data changes of each monitoring point, the specific location of the fault is determined; the user is allowed to view other alarm information related to the current alarm through the joint query function. This helps users fully understand the fault situation and formulate effective response measures.

[0044] The present invention utilizes sensors installed on the power equipment to obtain the current, voltage, power, electricity, temperature and time information of the power equipment, utilizes the image acquisition device installed in the power supply room to obtain the image information of the power equipment, and associates the power equipment information, power equipment customer information and operation and maintenance contract information to form a closed-loop process of "creating customer information → creating operation and maintenance equipment files → creating delegated equipment operation and maintenance contracts → delegating operation and maintenance staff → operation and maintenance staff performing work → feedback on equipment operation and maintenance results", so that the power supply operator can meet the maintenance needs of different customers for power equipment.

[0045] The present invention realizes real-time monitoring of the status of power equipment, so that hidden dangers can be discovered in time, equipment abnormalities can be handled in time, and the functions of electricity and power parameter statistics and analysis can be performed, forming an "online monitoring + offline maintenance + power guarantee" power equipment maintenance service mode to meet the maintenance needs of different customers for power equipment. Through the Internet of Things layer, application layer and service layer, an operation and maintenance service platform for power users is constructed to meet the diversified power equipment maintenance needs of power users due to differences in industry attributes and capacity scale.

[0058] The application layer includes an energy efficiency management module and a video monitoring module; wherein the energy efficiency management module constructs a corresponding topological structure according to the power lines provided by the Internet of Things layer, configures line association relationships, and sets alarm rules; when abnormal data that meets the alarm rules is monitored, it performs association analysis based on the line association relationships, compares the data changes of each monitoring point, and determines the location of the fault;

[0059] The service layer is used to generate a corresponding operation and maintenance work order according to the fault monitoring result of the application layer and send it to the corresponding inspection information entry terminal.

[0060] like Figure 1As shown, the Internet of Things layer includes a wireless communication module, a clock module, a data sensor, an equipment monitoring terminal and an Internet of Things management terminal respectively connected to the controller. The Internet of Things layer is connected to the application layer through the wireless communication module. The data sensor obtains the current, voltage, power, electricity, temperature and time information of the power equipment and transmits it to the Internet of Things management terminal. The Internet of Things management terminal transmits it to the application layer through the wireless communication module.

[0061] The application layer has an energy efficiency management module and a video monitoring module. The energy efficiency management module uses the current, voltage, power and power information of the power equipment to obtain the power consumption, power consumption and electricity fee of the set power supply interval; the video monitoring module uses the image acquisition device set in the power supply room to obtain the image information of the power equipment;

[0062] The service layer is connected to the application layer and has a storage device for storing power equipment information, power equipment user information and operation and maintenance contract information.

[0063] The data sensor has at least one group of mutual inductors and a temperature sensor installed on the power equipment. The temperature sensor has a temperature acquisition circuit. The temperature acquisition circuit acquires the oil layer temperature information of the transformer of the power equipment.

[0064] Environmental parameter information is formed by using the image information of the power equipment collected by the image acquisition device and the oil layer temperature information of the transformer of the power equipment obtained previously.

[0065] The transformer obtains the voltage and current information of the power equipment.

[0066] The data sensor also has a metering chip, which obtains the electricity quantity information and power information of the power equipment.

[0067] The power equipment information stored in the service layer includes the location information of the power equipment.

[0068] The application layer is also connected to the Internet of Things management terminal. The Internet of Things management terminal device has a positioning module. The location information of the Internet of Things management terminal obtained by the positioning module and the location information of the power equipment saved by the service layer are both sent to the application layer.

[0069] The details are as follows:

[0070] The system has a server access terminal, through which it interacts with the smart operation and maintenance customer service platform, application layer and service layer.

[0071] The service layer is used to create customer information files, equipment files, and operation and maintenance contract files. It is responsible for coordinating the closed-loop process of "creating customer information → creating operation and maintenance equipment files → creating delegated equipment operation and maintenance contracts → delegating operation and maintenance staff → operation and maintenance staff performing work → feedback on equipment operation and maintenance results" between the equipment manufacturer and the equipment operation and maintenance party;

[0072] The application layer is used to provide instantaneous quantity, electric energy, demand, environmental parameters, upper oil temperature of the equipment, and data analysis services of the power equipment, and provide basic query and monitoring function services for the service layer;

[0073] Specifically, the application layer includes two modules: energy efficiency management and video surveillance management. Energy efficiency management includes five functional modules: online monitoring, power consumption overview, maximum demand, real-time power statistics and energy efficiency report. Video surveillance management includes two functional modules: real-time monitoring and video playback.

[0074] The storage layer is used to provide data storage functions for the smart operation and maintenance customer service platform;

[0075] The station control layer is used to control the monitoring points and camera monitoring parameters of the on-site monitoring terminals of power equipment;

[0076] The IoT layer is used to provide IoT monitoring services for the service layer and the smart operation and maintenance customer service platform. The energy monitoring terminal in the equipment monitoring terminal collects data on the energy consumption of power equipment through data sensors, and then transmits the collected data to the IoT management terminal through lora wireless transmission technology for aggregation, and finally transmits it to the application layer of the system through the 4G IoT card in the IoT management terminal. It realizes equipment monitoring and maintenance services and records equipment maintenance information.

[0077] The interaction between each level:

[0078] The application layer configures the Internet of Things management terminal interface unit in the on-site handover management module, and calls the Internet of Things management terminal through the station control layer to collect the energy consumption information and environmental information of the power equipment, and transmits the above information to the service layer through the data transmission function in the Internet of Things layer. The Internet of Things layer summarizes and coordinates the low-voltage metering terminals, environmental sensor detectors, cameras and other equipment monitoring terminals to collect the current energy consumption status information and surrounding environment information of the power equipment, and uses the Internet of Things management terminal to transmit the collected information to the service layer through the application layer. If the monitoring data received by the application layer is abnormal, an alarm message will be transmitted in the service layer, and then the service layer will inspect and dispatch the equipment of the station control layer.

[0079] The service layer includes system management module, on-site handover management module and operation and maintenance management module.

[0080] The system management module includes the file management unit, the on-site handover management module includes the maintenance contract unit, the handover dispatch unit, and the monitoring terminal interface configuration unit, and the operation and maintenance operation management module includes the inspection plan unit and the maintenance dispatch unit.

[0081] The file management unit is used for customer file management, maintenance facility file management, and monitoring point file management.

[0082] The on-site handover management module is used to configure the equipment monitoring point interface, draft equipment maintenance contracts based on the equipment type and maintenance work mode that the customer needs to maintain, and then hand over equipment operation and maintenance to the equipment maintenance party.

[0083] The operation and maintenance management module is a service module for the equipment maintenance entrustee to formulate inspection plans and assign repair workers.

[0084] The file management unit in the system management module records the customer information file and then delegates it to the equipment operation and maintenance unit through the on-site handover management module. Finally, the equipment operation and maintenance unit completes the inspection plan and maintenance dispatch through the operation and maintenance operation management module.

[0085] The operation and maintenance monitoring service provides interactive services between the application layer and the storage layer, the Internet of Things layer, and the station control layer.

[0086] The party whose equipment is operated and maintained is responsible for the operation of the entire smart operation and maintenance customer service system; the party that operates and maintains the equipment implements the inspection and maintenance plan of the smart operation and maintenance customer service system.

[0087] Take the business process of maintenance personnel of a power supply operator performing equipment maintenance on power equipment of a power user within an operation and maintenance contract period as an example:

[0088] Maintenance personnel carry mobile terminal devices and arrive at the equipment site. They use the positioning function of the mobile terminal to match the longitude and latitude of the equipment site in the contract, so as to clock in and out at a fixed time and location at the work site.

[0089] At the beginning of the contract period, the maintenance personnel will conduct regular inspections of the equipment according to the inspection cycle agreed in the contract. After the inspection work is completed, the customer equipment ledger for inspection and maintenance will be entered into the system and the inspection plan will be executed in the service layer. During the execution process, the work records of the maintenance equipment will be entered into the service layer, and the maintenance records of the faulty equipment will be reflected in the operation and maintenance files. The above work will eventually generate regular operation and maintenance reports in the application layer.

[0090] The above system helps power supply operators build a service system through an information platform to meet the business service needs of different customers such as real-time equipment detection, daily inspections, fault repair, and fault maintenance.

[0091] It realizes functions such as real-time monitoring of power equipment, timely discovery of safety hazards, timely handling of equipment abnormalities, and statistical analysis of electrical quantity parameters.

[0092] The first level is the application layer, and the functions of this level mainly include two modules: energy efficiency management and video monitoring. Energy efficiency management includes online monitoring, power consumption overview, maximum demand, and real-time power statistics; video monitoring management includes real-time monitoring and video playback; energy efficiency management can realize the current, voltage, and power statistics of power equipment, the maximum power consumption statistics of intervals, power consumption and electricity fee statistics, and the generation of monthly monitoring reports; video monitoring management can realize the two functions of real-time monitoring of the distribution room and retrieving the interval monitoring content in the distribution room.

[0093] The second level is the service layer, which mainly includes three parts: system management, on-site handover, and operation and maintenance. The functions of this level mainly include file management, maintenance contracts, handover assignments, handover reports, inspection plans, maintenance assignments, operation and maintenance files, and data report formation.

[0094] The third level mainly includes three parts: storage layer, Internet of Things layer, and station control layer. The storage layer provides data storage function for the smart operation and maintenance customer service platform system; the station control layer is responsible for controlling the operation of monitoring video equipment and energy monitoring terminals.

[0095] like Figure 2 As shown in the figure, the IoT layer is used to provide the application layer with the service of the operating status of the power equipment, and is responsible for realizing the monitoring of the energy consumption of the equipment and generating data reports. The IoT layer consists of a switching power supply, a data sensor, a data transmission port, a CPU, a storage chip, a wireless communication module, and an equipment monitoring terminal. The operating parameters of the power equipment are collected through the equipment monitoring terminals such as the "data sensor". These external devices are connected to the IoT management terminal through the "data transmission port" and transmit data. After the "switching power supply" is turned on, the "CPU" in the IoT management terminal device starts to start and call the built-in system in the "storage chip". According to the parameters set by the "real-time clock", the "CPU" will intermittently call the built-in system. After the built-in system is called, the "CPU" will obtain the data transmitted by the equipment monitoring terminal and write the data into the "storage chip". Finally, the obtained data will be transmitted to the "application layer" of the system through the "wireless communication module".

[0096] The Internet of Things layer is composed of a switching power supply, a data sensor, a data transmission port, a CPU, a storage chip, a wireless communication module and an equipment monitoring terminal;

[0097] The operating parameters of the power equipment are collected through the data sensor, and the data sensor is connected to the equipment monitoring terminal through the data transmission port and transmits data;

[0098] After the CPU is powered on, it starts to boot and calls the built-in system in the memory chip. The CPU will intermittently call the built-in system according to the parameters set by the real-time clock.

[0099] After the built-in system is called, the CPU will obtain the data transmitted by the device monitoring terminal and write the data into the storage chip, and finally transmit the obtained data to the application layer through the wireless communication module.

[0100] The application layer consists of the front-end interface and the back-end application. It can query and display the operating parameters of the power equipment fed back by the equipment monitoring terminal, and coordinate the closed-loop process of "formulating inspection plans → dispatching maintenance workers → recording operation and maintenance files → forming operation and maintenance reports".

[0101] Customers need to access the application layer through the corresponding server, which needs to have storage function, data processing capability, network connection function, and the ability to install relevant software of the smart operation and maintenance customer service platform system (such as the Internet of Things installation module, the station control layer control module, etc.), display screen, motherboard, and data transmission interface unit. For example, the server can be a mobile client, a computer client, etc. Customers can access the smart operation and maintenance customer service platform system by installing the corresponding application.

[0102] The application layer mainly provides data monitoring services, including current, voltage, and power statistics of power equipment, statistics on maximum power consumption in intervals, statistics on power consumption and electricity charges, and generation of monthly monitoring reports, etc., providing the service layer with real-time transmission of power equipment operating parameters and timely feedback of alarm signals. Among them, the "power consumption overview" mainly counts equipment power parameters, equipment operating environment, power consumption, electricity charges and other data. If the above data triggers the alarm rules in the service layer, the dispatching service of maintenance dispatch will occur. The dispatching service mainly provides interactive services between the application layer and the storage layer, the Internet of Things layer, and the station control layer. The equipment maintenance project team is responsible for the operation of the entire smart operation and maintenance customer service platform system.

[0103] In the smart operation and maintenance customer service platform system, interfaces are set up between the application layer and the service layer, and between the service layer and the storage layer, the Internet of Things layer, and the station control layer for data access and transmission.

[0104] In summary, by establishing a smart operation and maintenance customer service platform system and accessing IoT terminals, we can effectively meet the diversified business service needs of diversified customer service needs, differentiated industry attributes, and differentiated capacity and scale, and achieve effective management and working methods to meet the business service needs of equipment real-time detection, daily inspections, fault repair, and fault maintenance of different customer attributes. Provide high-quality, efficient, and visual equipment maintenance services.

[0105] This embodiment includes an Internet of Things layer, an application layer, and a service layer; the Internet of Things layer includes a wireless communication module, a clock module, and a sensor module respectively connected to the controller. The Internet of Things layer is connected to the application layer through the wireless communication module. The sensor module obtains the current, voltage, power, electricity, temperature, and time of the power equipment and transmits them to the application layer through the wireless communication module; the application layer has an energy efficiency management module and a video monitoring module. The energy efficiency management module uses the current, voltage, power, and electricity information of the power equipment to obtain the power consumption, electricity consumption, and electricity fee of the set power supply interval; the video monitoring module uses the image acquisition device set in the power supply room to obtain the image information of the power equipment; the service layer is connected to the application layer and has a memory to store the power equipment information, the power equipment user information, and the operation and maintenance contract information. It enables the power supply operator to meet the maintenance needs of different customers for power equipment.

[0106] Embodiment 2

[0107] This embodiment provides an IoT-driven distributed energy monitoring method, which is based on the operation of an IoT-driven distributed energy monitoring system as described in Embodiment 1, and includes:

[0108] Use the positioning function of the inspection information input terminal device to match the latitude and longitude of the power equipment site in the operation and maintenance contract, so as to obtain the punch-in information of the maintenance personnel at a fixed time and point at the work site;

[0109] At the beginning of the contract period, the maintenance personnel will conduct regular inspections on the power equipment according to the inspection cycle agreed in the contract. After the inspection, the customer's power equipment ledger for inspection and maintenance will be entered into the system and the inspection plan will be executed in the service layer. During the execution, the work records of the maintenance equipment will be entered into the service layer, and the maintenance records of the faulty equipment will be reflected in the operation and maintenance files. The above work will eventually generate operation and maintenance reports regularly in the application layer.

[0110] During the inspection process, the corresponding topological structure is constructed according to the power lines, the line association relationship is configured, and the alarm rules are set; when abnormal data that meets the alarm rules is monitored, correlation analysis is performed based on the line association relationship, and the data changes of each monitoring point are compared to determine the location of the fault.

[0112] Establish a corresponding topological structure according to the power line, including the bus, branch lines and their connection relationships;

[0113] According to the actual situation of the power system, configure the total-score relationship between the line corresponding to a specific monitoring point and the lines corresponding to other monitoring points;

[0114] According to the operation specifications and experience data of the power system, set the alarm thresholds corresponding to various power operation data for each monitoring point;

[0115] Configure alarm conditions based on alarm thresholds.

[0116] Furthermore, when abnormal data that meets the alarm rules is monitored, correlation analysis is performed based on the line association relationship, and the data changes of each monitoring point are compared to determine the location of the fault, specifically:

[0117] When the power operation data of the power equipment is monitored to be greater than the corresponding alarm threshold, it is determined whether the equipment has a lower-level device. If so, it is determined whether the lower-level device has an alarm; otherwise, it is determined that the equipment has exceeded the limit and an alarm has been issued;

[0118] If the lower-level device alarms, determine whether the operation data of the lower-level device is consistent with that of the current device alarm. If so, determine whether the same operation data of the lower-level device and the current device alarm is greater than the alarm threshold; otherwise, determine that the current device operation data alarms while the lower-level device does not have the same operation data alarm;

[0119] If the same operating data of the lower-level device and the current device is greater than the alarm threshold, the same operating data of the current device and the lower-level device will simultaneously exceed the upper limit alarm, and the correlation relationship will be displayed; otherwise, the same operating data of the current device and the lower-level device will alarm at the same time, but the lower-level device will alarm when the data is lower than the alarm threshold.

[0120] 1. Configure line association

[0121] (1) Establishing a line model: First, establish a power line model in the system, including the bus, branch lines and their connections. The model accurately reflects the actual topology of the power system.

[0122] (2) Configure the total-branch relationship: According to the actual situation of the power system, configure the total-branch relationship between the line corresponding to a specific monitoring point and the lines corresponding to other monitoring points. This includes determining which branches belong to which bus branch, and the relative position relationship between the branches.

[0123] (3) Verify the association relationship: After configuration is completed, verify the accuracy of the association relationship through simulation testing or actual operation data to ensure that the system can correctly identify and process the total-score relationship between lines.

[0124] 2. Set up smart alarm rules

[0125] (1) Define alarm thresholds: According to the power system operation specifications and empirical data, set reasonable current, voltage and other alarm thresholds for each monitoring point. These thresholds should be able to reflect the normal operation status and possible fault conditions of the power system.

[0126] (2) Configure alarm conditions: Configure alarm conditions based on alarm thresholds. For example, when the current at a monitoring point exceeds the set threshold, an alarm is triggered.

[0127] (3) Enable correlation analysis: Figure 3 As shown in the figure, taking the current alarm as an example, the correlation analysis function is enabled in the alarm rule. When the alarm is triggered, the system will automatically analyze and determine the location and cause of the possible fault based on the configured correlation relationship. The same process is used for the analysis of other power operation parameter alarms.

[0128] 3. Alarm processing and correlation analysis

[0129] (1) Alarm triggering and notification: When the system detects data that meets the alarm conditions, it immediately triggers the alarm and notifies relevant personnel via SMS, email, etc.

[0130] (2) Correlation analysis and location: The system conducts correlation analysis on the alarm information based on the configured correlation relationship. By comparing the data changes of each monitoring point, the specific location of the fault is determined.

[0131] (3) Joint query of related alarm information: Allows users to view other alarm information related to the current alarm through the joint query function. This helps users fully understand the fault situation and formulate effective response measures.

[0132] The examples and application scenarios implemented by the above modules and corresponding steps are the same, but are not limited to the contents disclosed in the above embodiment 1. It should be noted that the above modules as part of the system can be executed in a computer system such as a set of computer executable instructions.

[0133] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
