Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0018] Figure 1 It is a schematic diagram of system module connection of the present invention. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 As shown, the present invention provides a power information security operation and maintenance management system, and the specific modules are distributed as follows: information security analysis module, equipment operation security analysis module, power dispatching information analysis module, operation and maintenance demand judgment module, operation and maintenance management control module and database. Among them, the connection mode between the modules is: the information security analysis module is connected to the equipment operation security analysis module, the equipment operation security analysis module is connected to the power dispatching information analysis module, the power dispatching information analysis module is connected to the operation and maintenance demand judgment module, the operation and maintenance demand judgment module is connected to the operation and maintenance management control module, and the database is connected to the information security analysis module and the equipment operation security analysis module respectively.

[0021] The information security analysis module is used to obtain network security data parameters of the power information of the target power grid within a preset monitoring period, analyze the network security indicators of the power information of the target power grid within the preset monitoring period, and feedback them.

[0022] As a preferred feasibility example, the network security data parameters of the power information of the target power grid within the predetermined interval period include external network security data parameters and internal network security data parameters.

[0023] Among them, external network security data parameters include the number of abnormal sources, the number of sudden increase in data packets and the integrity of data transmission.

[0024] It should be further explained that the reasons for using the number of abnormal sources, the number of sudden increase in data packets, and the integrity of data transmission as external network security data parameters of the target power grid's power information are: (1) External abnormal sources usually refer to those unauthorized or abnormal network connection attempts, such as malicious scanning and attacks from the Internet. The number of abnormal sources reflects the number of potential unsafe factors or attack sources in the power grid information system, and reflects the security situation of the power grid information system.

[0025] (2) A burst of packets usually refers to a sudden increase in the number of packets in a short period of time, which may be caused by attacks, network congestion or other abnormal situations. The number of burst packets is one of the important indicators for detecting network attacks. For example, DDoS attacks usually result in a large number of sudden connection attempts and packet transmissions. The number of burst packets may also affect the performance and stability of the network.

[0026] (3) Data transmission integrity usually refers to the degree to which data remains intact during the transmission process. Data transmission integrity is an important indicator for evaluating the quality of power information transmission. If errors or losses occur during data transmission, it may lead to inaccurate information or inability to use it normally, which in turn affects the operating efficiency and safety of the power system.

[0027] It needs to be further explained that the specific method of obtaining the number of external abnormal sources of the target power grid's power information, the number of sudden increase in data packets and the integrity of data transmission is: deploying an intrusion detection platform at the network boundary of the target power grid, and then using the detection rules of the intrusion detection platform to directly detect and count the number of external abnormal sources of the target power grid's power information.

[0028] The network traffic monitoring tool is used to monitor the network traffic of the target power grid in real time, and a threshold for traffic surge is set. When the threshold is exceeded, it is considered a surge. Each surge in the network traffic of the target power grid is further recorded and counted to obtain the number of external surge data packets of the target power grid's power information.

[0029] The sender calculates the checksum of the data packet and sends the data packet and the checksum to the receiver. The receiver receives the data packet and the checksum, recalculates the checksum, and further divides it with the checksum sent by the sender. The quotient is recorded as the external data transmission integrity of the power information of the target power grid.

[0030] Internal network security data parameters include the number of unauthorized clicks and erroneous clicks by each employee.

[0031] It should be further explained that the reasons for using the number of unauthorized clicks and erroneous clicks of each employee as the internal network security data parameters of the target power grid's power information are: (1) The number of unauthorized clicks reflects the possible illegal operation behavior of employees. By monitoring this data parameter, it is possible to promptly detect whether employees attempt to access or operate system resources outside their authority, thereby avoiding potential security risks. It also allows us to understand the security awareness and compliance level of employees. If the number of unauthorized clicks of an employee is abnormally high, it may mean that their authority settings are unreasonable or there are security vulnerabilities.

[0032] (2) The number of erroneous operation clicks reflects the mistakes that may occur when employees operate the power grid information system. By monitoring this data parameter, enterprises can promptly discover and correct employees' erroneous operation behaviors and reduce system abnormalities or safety accidents caused by operational errors. If the number of erroneous operation clicks on a certain function is high, it may mean that the user interface design of the function is not friendly enough or misleading. Through this data parameter, enterprises can promptly discover and optimize the user interface design to improve the usability and safety of the system.

[0033] It needs to be further explained that the specific method of obtaining the number of unauthorized clicks and erroneous clicks of each employee within the target power grid's electricity information is as follows: directly extracting the number of unauthorized clicks and erroneous clicks of each employee within the target power grid's electricity information from the user behavior log records in the target power grid platform.

[0034] As a preferred feasibility example, the network security indicators of the power information of the target power grid within the preset monitoring period are specifically analyzed in the following manner: extracting the number of external abnormal sources, the number of sudden increase data packets and the completeness of data transmission of the power information of the target power grid within the preset monitoring period, and analyzing the external influence index of the network security indicators of the power information of the target power grid within the preset monitoring period. .

[0035] Extract the number of unauthorized clicks and erroneous clicks of each employee within the power information of the target power grid within the preset monitoring period, and analyze the internal impact index of the network security indicators of the power information of the target power grid within the preset monitoring period. .

[0036] Analyze the network security indicators of the target power grid's power information within the preset monitoring period ,in are the weight factors corresponding to the external impact index and internal impact index of the set network security indicators, is the inverse hyperbolic sine function.

[0037] It should be further explained that the weight factors corresponding to the external impact index and the internal impact index of the set network security indicator can be set to 0.6 and 0.4 respectively.

[0038] The external impact of cybersecurity incidents usually involves a wider range of stakeholders, including customers, partners, regulators, and the public. These impacts may include reputation damage, legal proceedings, compliance issues, and business interruptions, and these consequences are often more serious and difficult to predict. Therefore, the weight factor corresponding to the external impact index of the cybersecurity indicator is assigned a value of 0.6.

[0039] Internal impacts mainly focus on security risks within the organization, such as data leakage, system paralysis, internal fraud, etc. Although these risks pose a threat to organizational operations and asset security, their impact is usually more limited than external impacts. Therefore, the weight factor corresponding to the internal impact index of the network security indicator is assigned a value of 0.4.

[0040] As a preferred feasibility example, the external impact index of the network security indicator of the power information of the target power grid within the preset monitoring period is specifically obtained by extracting the number of external abnormal sources of the power information of the target power grid within the preset monitoring period, the number of sudden increase data packets and the data transmission integrity, which are respectively recorded as , analyze the external impact index of the network security indicators of the target power grid's power information within the preset monitoring period ,in The external data transmission integrity tolerance difference of the power information of the target power grid extracted from the database.

[0041] As a preferred feasibility example, the internal impact index of the network security indicator of the power information of the target power grid within the preset monitoring period is specifically analyzed in the following manner: extracting the number of unauthorized clicks and the number of erroneous clicks of each employee within the power information of the target power grid within the preset monitoring period, and recording them as ,in , is the number of each employee, Analyze the internal impact index of network security indicators of power information of the target power grid within the preset monitoring period for the number of employees ,in They are respectively the number of permitted over-authority clicks and the number of permitted erroneous operation clicks of internal employees of the target power grid's power information within a preset monitoring period extracted from the database.

[0042] The present invention analyzes the network security indicators of the power information of the target power grid within a preset monitoring period and determines its network security operation and maintenance needs, which helps to timely discover network security risks in the power grid and formulate targeted operation and maintenance plans, avoiding the blindness and inefficiency of traditional operation and maintenance methods, improving the pertinence and efficiency of operation and maintenance work, and thus ensuring the security of the power information corresponding to the power grid.

[0043] The equipment operation safety analysis module is used to obtain the operation safety data parameters of the power equipment operation information of the target power grid within a preset monitoring period, analyze the operation safety indicators of the power equipment operation information of the target power grid, and provide feedback.

[0044] As a preferred feasibility example, the operation safety data parameters of the power equipment operation information of the target power grid include the voltage, current and frequency of the power grid and the voltage, current and power factor of each power transmission equipment.

[0045] It should be further explained that the reasons for using the voltage, current and frequency of the power grid and the voltage, current and power factor of each power transmission device as the operation safety data parameters of the power equipment operation information of the target power grid are: (1) The stability of the power grid voltage is directly related to the normal operation of the power equipment. Excessive voltage fluctuations may cause equipment damage, low operating efficiency or even failure and shutdown. For high-precision equipment such as computers and medical equipment, voltage instability will directly affect their performance and life.

[0046] (2) The stability of grid current is critical to grid operation. Current fluctuations may cause equipment overheating, damage or failure. During power transmission, stable current can reduce energy loss and improve power transmission efficiency. Current imbalance may cause three-phase load imbalance, generate additional loss and heat, affect the normal operation of equipment, and long-term unbalanced current may also cause equipment damage or performance degradation.

[0047] (3) The stability of the grid frequency is crucial to the normal operation of power equipment. Frequency fluctuations may cause the equipment to malfunction or even be damaged.

[0048] (4) The voltage and current of power transmission equipment are important parameters that reflect its operating status. By monitoring these parameters, abnormal conditions such as overload and short circuit of the equipment can be discovered in time to ensure the safe operation of the equipment.

[0049] (5) Power factor is the ratio of active power to apparent power, which reflects the energy efficiency of power equipment. A low power factor means that there is a large amount of reactive power flowing in the power grid, which will lead to problems such as increased power grid losses and severe equipment heating. By monitoring the power factor, these problems can be discovered and dealt with in a timely manner, thereby improving the energy efficiency of the power grid.

[0050] It needs to be further explained that the specific method of obtaining the voltage, current and frequency of the power grid of the target power grid and the voltage, current and power factor of each power transmission equipment of the power equipment operation information is: directly extracting the voltage, current and frequency of the power grid of the target power grid and the voltage, current and power factor of each power transmission equipment of the power equipment operation information from the power equipment operation information record log of the target power grid.

[0051] As a preferred feasibility example, the operation safety index of the power equipment operation information of the target power grid within the preset monitoring period is specifically obtained by: extracting the voltage, current and frequency of the power grid of the power equipment operation information of the target power grid within the preset monitoring period, analyzing the power grid operation safety index of the power equipment operation information of the target power grid .

[0052] Extract the voltage, current and power factor of each power transmission device of the power equipment operation information of the target power grid within the preset monitoring period, and analyze the power transmission equipment operation safety index of the power equipment operation information of the target power grid .

[0053] Analyze the operation safety indicators of the power equipment operation information of the target power grid within the preset monitoring period .

[0054] As a preferred feasibility example, the power grid operation safety index and the power transmission equipment operation safety index of the power equipment operation information of the target power grid within the preset monitoring period are specifically analyzed in the following manner: extracting the voltage, current and frequency of the power grid of the power equipment operation information of the target power grid within the preset monitoring period, and recording them as , analyze the grid operation safety indicators of the target grid’s power equipment operation information within the preset monitoring period ,in are respectively the standard voltage, standard current and standard frequency of the power grid of the target power grid in the preset monitoring period extracted from the database, They are the allowable difference between the set voltage and the standard voltage, the allowable difference between the current and the standard current, and the allowable difference between the frequency and the standard frequency.

[0055] It should be further explained that the allowable difference between the set voltage and the standard voltage, the allowable difference between the current and the standard current, and the allowable difference between the frequency and the standard frequency can be set to 0.01 volts, 0.01 amps, and 0.01 hertz, respectively, which means that a deviation of one percent is allowed between the voltage and the standard voltage, the current and the standard current, and the frequency and the standard frequency.

[0056] The voltage, current and power factor of each power transmission device of the power equipment operation information of the target power grid within the preset monitoring period are extracted and recorded as ,in , is the number of each power transmission equipment, The number of transmission equipment is used to analyze the power transmission equipment operation safety index of the target power grid within the preset monitoring period. ,in are respectively the first and second information of the power equipment operation of the target power grid extracted from the database within the preset monitoring period. The standard voltage, standard current and standard power factor of each power transmission equipment, They are the allowable difference between the set voltage and the standard voltage, the allowable difference between the current and the standard current, and the allowable difference between the power factor and the standard power factor.

[0057] It should be further explained that the allowable difference between the set voltage and the standard voltage, the allowable difference between the current and the standard current, and the allowable difference between the power factor and the standard power factor can be set to 0.01 volts, 0.01 amps, and 0.01, respectively, which means that a deviation of one percent is allowed between the voltage and the standard voltage, the current and the standard current, and the power factor and the standard power factor.

[0058] The present invention analyzes the operating safety indicators of the target power grid's power equipment operating information and determines the power equipment's operating safety operation and maintenance needs, which helps operation and maintenance personnel to promptly discover abnormal conditions in the operation of power equipment, and then quickly locate potential problems, achieve precise operation and maintenance, improve the efficiency and accuracy of operation and maintenance work, ensure the stable operation of the power grid, improve users' electricity satisfaction, promote the intelligent development of the power industry, and ensure energy security.

[0059] The power dispatch information analysis module is used to obtain the security data parameters of the power dispatch information of the target power grid within the preset monitoring period, analyze the security indicators of the power dispatch information of the target power grid within the preset monitoring period, and feedback them.

[0060] As a preferred feasibility example, the security data parameters of the power dispatching information of the target power grid within the set monitoring period include power generation, power consumption, loss and storage.

[0061] It is necessary to further explain that the reasons for using power generation, power consumption, loss and storage as the security data parameters of the power dispatching information of the target power grid within the set monitoring period are: (1) Power generation is one of the core parameters in power dispatching, which directly determines the total amount of power that the power grid can provide. By monitoring power generation, we can understand the power supply capacity of the power grid in real time, ensure the balance of power supply and demand, and prevent the operation risks of the power grid caused by insufficient or excessive power supply.

[0062] (2) Electricity consumption is an important indicator reflecting the load of the power grid. By monitoring electricity consumption, we can accurately predict future electricity demand and provide a scientific basis for power dispatching. This helps to achieve a dynamic balance between electricity supply and demand and ensure the stable operation of the power grid.

[0063] (3) The amount of loss reflects the loss of the power grid during the transmission and distribution of electricity. By monitoring the amount of loss, abnormal losses in the power grid can be discovered in a timely manner, providing a basis for power grid maintenance and optimization. This helps to reduce power grid losses and improve the efficiency of power transmission and distribution.

[0064] (4) Storage capacity reflects the amount of power resources available for regulation and storage in the power grid. By monitoring storage capacity, power resources can be properly allocated to ensure that sufficient power support can be provided during peak power demand and that excess power resources can be stored during low power demand.

[0065] It needs to be further explained that the specific method of obtaining the power generation, power consumption, loss and storage capacity of the power dispatching information of the target power grid within the set monitoring period is: directly extracting the power generation, power consumption, loss and storage capacity of the power dispatching information of the target power grid within the set monitoring period from the power dispatching information record log of the target power grid.

[0066] As a preferred feasibility example, the safety index of the power dispatching information of the target power grid within the preset monitoring period, its specific analysis method includes: extracting the power generation, power consumption, loss and storage of the power dispatching information of the target power grid within the preset monitoring period, respectively recorded as , analyze the safety indicators of the power dispatch information of the target power grid within the preset monitoring period ,in is a natural constant.

[0067] The operation and maintenance demand judgment module is used to judge the network security operation and maintenance demand of the target power grid's power information, the power equipment operation security operation and maintenance demand, and the power dispatching security operation and maintenance demand.

[0068] As a preferred feasibility example, the specific judgment method for the network security operation and maintenance requirements of the target power grid's power information, the power equipment operation security operation and maintenance requirements, and the power dispatching security operation and maintenance requirements is: extracting the network security indicators of the target power grid's power information, the operation safety indicators of the power equipment operation information, and the safety indicators of the power dispatching information within a preset monitoring period.

[0069] The network security index of the power information of the target power grid within the preset monitoring period is compared with the set network security index threshold of the power information. If the network security index of the power information of the target power grid within the preset monitoring period is less than the network security index threshold of the power information, the network security operation and maintenance demand of the power information of the target power grid is recorded as requiring network security operation and maintenance demand; otherwise, the network security operation and maintenance demand of the power information of the target power grid is recorded as not requiring network security operation and maintenance demand.

[0070] Similarly, the power information of the target power grid can be used to obtain the power equipment operation safety and maintenance requirements and power dispatching safety and maintenance requirements.

[0071] The operation and maintenance management and control module is used to manage and control the network security operation and maintenance requirements of the target power grid's power information, the power equipment operation security operation and maintenance requirements, and the power dispatching security operation and maintenance requirements.

[0072] As a preferred feasibility example, the specific operations of managing and controlling the network security operation and maintenance requirements of the target power grid's power information, the power equipment operation security operation and maintenance requirements, and the power dispatching security operation and maintenance requirements are as follows: extracting the network security operation and maintenance requirements of the target power grid's power information, the power equipment operation security operation and maintenance requirements, and the power dispatching security operation and maintenance requirements, and if they require security operation and maintenance requirements, they are further managed and controlled according to predefined principles.

[0073] It should be further explained that the specific contents of the predefined principles in the management and control of the network security operation and maintenance requirements of the target power grid's power information, the power equipment operation security operation and maintenance requirements, and the power dispatching security operation and maintenance requirements according to the predefined principles include: Management and control of the network security operation and maintenance requirements of the target power grid's power information: (1) Scan the network system for vulnerabilities, promptly discover potential security vulnerabilities, and conduct risk assessment.

[0074] (2) Take timely repair measures for discovered vulnerabilities and strengthen patch management to ensure that the system is updated in a timely manner.

[0077] (2) Conduct real-time dispatch and monitoring of the power system and adjust the dispatch strategy in a timely manner to respond to various changes in system operation.

[0078] (3) Provide safety training and assessment to dispatchers to improve their safety awareness and skill level.

[0079] (4) Regularly evaluate dispatch safety, make timely improvements when problems are discovered, and continuously improve the level of dispatch safety.

[0080] The database is used to store the permitted difference in data transmission integrity of the external power information of the target power grid, the number of permitted unauthorized clicks and the number of permitted erroneous operation clicks of the internal employees of the target power grid within a preset monitoring period, and the standard voltage, standard current and standard frequency of the power grid and the standard voltage, standard current and standard power factor of each power transmission equipment of the power equipment operation information of the target power grid within a preset monitoring period.

[0081] The present invention helps to timely discover safety hazards such as supply and demand imbalance and excessive losses in the grid dispatching process by analyzing the safety indicators of the power dispatching information of the target power grid within a preset monitoring period and judging its power dispatching safety operation and maintenance needs.
