Fig. 1 is a schematic diagram of a system module connection according to the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the invention provides a power information security operation and maintenance management and control system, and specific modules are distributed as follows: the system comprises an information security analysis module, an equipment operation security analysis module, a power dispatching information analysis module, an operation and maintenance requirement judgment module, an operation and maintenance management control module and a database. The connection mode between the modules is as follows: the information security analysis module is connected with the equipment operation security analysis module, the equipment operation security analysis module is connected with the power dispatching information analysis module, the power dispatching information analysis module is connected with the operation and maintenance requirement judgment module, the operation and maintenance requirement judgment module is connected with the operation and maintenance management control module, and the database is respectively connected with the information security analysis module and the equipment operation security analysis module.
The information safety analysis module is used for acquiring network safety data parameters of the electric power information of the target electric power network in a preset monitoring period, analyzing network safety indexes of the electric power information of the target electric power network in the preset monitoring period and feeding back the network safety indexes.
As a preferred practical example, the network security data parameters of the power information of the target power grid within the predetermined interval period include an external network security data parameter and an internal network security data parameter.
The external network security data parameters comprise the number of abnormal sources, the number of sudden increase data packets and the data transmission integrity.
It should be further described that, the reasons for the external network security data parameters using the number of abnormal sources, the number of sudden increase data packets and the data transmission integrity as the power information of the target power grid are as follows: (1) External sources of anomalies are typically referred to as those unauthorized or abnormal network connection attempts, such as malicious scans and attacks from the internet, and the like. The number of abnormal sources reflects the number of potential unsafe factors or attack sources in the power grid power information system and reflects the safety situation of the power grid power information system.
(2) Sudden data packets generally refer to a sudden increase in the number of data packets in a short period of time, which may be caused by an attack, network congestion, or other abnormal situation. The number of the sudden increase data packets is one of important indexes for detecting network attacks. For example, DDoS attacks typically result in a large number of bursty connection attempts and data packet transmissions. The number of bursty packets may also affect the performance and stability of the network.
(3) Data transmission integrity generally refers to the degree to which data remains intact during transmission. The data transmission integrity is an important index for evaluating the transmission quality of the power information. If errors or losses occur in the data transmission process, the information may be inaccurate or cannot be normally used, and therefore the operation efficiency and the safety of the power system are affected.
It should be further described that the specific acquisition modes of the number of external abnormal sources, the number of sudden increase data packets and the data transmission integrity of the power information of the target power grid are as follows: and deploying an intrusion detection platform at a network boundary of the target power grid, and further directly detecting and counting the number of external abnormal sources of the power information of the target power grid by utilizing the detection rule of the intrusion detection platform.
And monitoring the network flow of the target power grid in real time by using a network flow monitoring tool, setting a threshold value of the flow surge, regarding as the surge when the threshold value is exceeded, further recording each surge of the network flow of the target power grid, and counting the surge to obtain the number of external surge data packets of the power information of the target power grid.
The sender calculates the checksum of the data packet, sends the data packet and the checksum to the receiver, and the receiver receives the data packet and the checksum and recalculates the checksum, further performs division operation on the checksum and the checksum sent by the sender, and marks the obtained quotient as the external data transmission integrity of the power information of the target power grid.
The internal network security data parameters include the number of override clicks and the number of mishandling clicks for each employee.
It should be further described that, the reasons for taking the out-of-authority click number and the misoperation click number of each employee as the internal network security data parameters of the power information of the target power grid are as follows: (1) The number of more authorized clicks reflects the possible offensive behavior of the employee. By monitoring this data parameter, it is possible to discover in time whether an employee is attempting to access or operate a system resource outside of its authority range, thereby avoiding potential security risks. And also the security awareness and compliance level of the employee. If the number of unauthorized clicks of a particular employee is abnormally high, this may mean that its rights are unreasonable or that a security breach exists.
(2) The misoperation click number reflects possible error conditions of staff in operating the power grid power information system. By monitoring the data parameters, enterprises can timely find and correct misoperation behaviors of staff, and system abnormality or safety accidents caused by misoperation are reduced. If the number of misoperating clicks for a function is high, it may mean that the user interface design for that function is not sufficiently friendly or misleading. Through the data parameters, enterprises can discover and optimize the user interface design in time, and the usability and the safety of the system are improved.
It should be further described that the specific acquisition modes of the out-of-authority click number and the misoperation click number of each employee in the electric power information of the target power grid are as follows: and directly extracting the unauthorized click number and misoperation click number of each employee in the electric power information of the target power grid from the user behavior log record in the target power grid platform.
As a preferable feasible example, the network safety index of the power information of the target power grid in the preset monitoring period includes: extracting the number of abnormal sources, the number of sudden increase data packets and the data transmission integrity outside the power information of the target power grid in a preset monitoring period, and analyzing the external influence index of the network safety index of the power information of the target power grid in the preset monitoring period。
Extracting out-of-authority click number and misoperation click number of each employee in the electric power information of the target electric power grid in a preset monitoring period, and analyzing internal influence index of network safety index of the electric power information of the target electric power grid in the preset monitoring period。
Network security index for analyzing power information of target power grid in preset monitoring periodWhereinRespectively the weight factors corresponding to the external influence index and the internal influence index of the set network security index,Is an anti-hyperbolic sine function.
It should be further noted that the weight factors corresponding to the external impact index and the internal impact index of the set network security index may be set to 0.6 and 0.4, respectively.
The external impact of network security events typically involves a wider range of stakeholders, including clients, partners, regulatory authorities, and the public, among others. These effects may include reputation damage, legal litigation, compliance issues, and business outages, which are often more serious and difficult to predict. Therefore, the weight factor corresponding to the external influence index of the network security index is assigned to 0.6.
Internal influences are mainly concerned with security risks inside organizations, such as data leakage, system paralysis, internal fraud, etc. These risks, while threatening organization operation and asset security, are often limited in scope compared to external effects. Therefore, the weight factor corresponding to the internal influence index of the network security index is assigned to 0.4.
As a preferable feasible example, the external impact index of the network safety index of the power information of the target power grid in the preset monitoring period is specifically obtained by the following steps: extracting the number of external abnormal sources, the number of sudden increase data packets and the data transmission integrity of the power information of the target power grid in a preset monitoring period, and respectively recording asAnalyzing an external impact index of a network safety index of power information of a target power grid in a preset monitoring periodWhereinThe difference is permitted for data transmission integrity outside of the power information of the target grid extracted from the database.
As a preferable practical example, the internal impact index of the network safety index of the power information of the target power grid in the preset monitoring period, the specific analysis mode includes: extracting out-of-authority click number and misoperation click number of each staff in the electric power information of the target electric network in a preset monitoring period, and respectively recording asWherein，For the numbering of the staff members,For the number of staff, analyzing the internal impact index of the network safety index of the power information of the target power grid in the preset monitoring periodWhereinThe number of allowed override clicks and the number of allowed misoperation clicks of staff inside the power information of the target power grid in the preset monitoring period are extracted from the database respectively.
According to the invention, the network safety index of the power information of the target power grid in the preset monitoring period is analyzed, and the network safety operation and maintenance requirements are judged, so that the network safety hidden danger in the power grid can be found in time, a targeted operation and maintenance plan is formulated, blindness and inefficiency in the traditional operation and maintenance mode are avoided, the pertinence and efficiency of operation and maintenance work are improved, and the safety of the power information corresponding to the power grid is further ensured.
The equipment operation safety analysis module is used for acquiring operation safety data parameters of the power equipment operation information of the target power grid in a preset monitoring period, analyzing operation safety indexes of the power equipment operation information of the target power grid and feeding back the operation safety indexes.
As a preferred practical example, the operation safety data parameters of the power device 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 device.
It should be further noted that, the reasons for taking 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 device operation information of the target power grid are as follows: (1) The stability of the grid voltage is directly related to the normal operation of the electrical equipment. Excessive voltage fluctuations can lead to equipment damage, inefficiency in operation, and even downtime. For high precision devices such as computers, medical devices, etc., voltage instability can directly affect their performance and lifetime.
(2) The stability of the grid current is critical to the grid operation. Current fluctuations may cause the device to overheat, damage or malfunction. In the power transmission process, the stable current can reduce energy loss and improve power transmission efficiency. Current imbalance may cause three-phase load imbalance, generate additional losses and heat, affect the proper operation of the device, and long-term imbalance current may also cause device damage or performance degradation.
(3) The stability of the grid frequency is critical to the proper operation of the electrical equipment. Frequency fluctuations may cause the device to fail or even fail.
(4) The voltage and current of the power transmission device are important parameters reflecting the operating state thereof. By monitoring the parameters, abnormal conditions such as overload and short circuit of the equipment can be found in time, and the safe operation of the equipment is ensured.
(5) The power factor is the ratio of active power to apparent power, which reflects the efficiency of electrical energy utilization of the electrical device. A low power factor means that there is a lot of reactive power flow in the grid, which can lead to problems of increased grid losses, severe heating of the equipment, etc. By monitoring the power factor, the problems can be found and processed in time, and the electric energy utilization efficiency of the power grid is improved.
It should be further described that the specific acquisition modes of the voltage, the current and the frequency of the power grid of the power equipment operation information of the target power grid and the voltage, the current and the power factor of each power transmission equipment are as follows: and directly extracting the voltage, current and frequency of the power grid of the power equipment operation information of the target power grid from the power equipment operation information log of the target power grid, and the voltage, current and power factor of each power transmission equipment.
As a preferable feasible example, the operation safety index of the power equipment operation information of the target power grid in the preset monitoring period is specifically obtained by the following steps: extracting voltage, current and frequency of a power grid of power equipment operation information of a target power grid in a preset monitoring period, and analyzing power grid operation safety indexes of the power equipment operation information of the target power grid。
Extracting voltage, current and power factor of each power transmission device of power device operation information of target power grid in preset monitoring period, and analyzing power transmission device operation safety index of power device operation information of target power grid。
Analyzing operation safety index of power equipment operation information of target power grid in preset monitoring period。
As a preferable feasible 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 in the preset monitoring period specifically analyze the power grid operation safety index and the power transmission equipment operation safety index in the specific analysis mode includes: the voltage, current and frequency of the power grid for extracting the power equipment operation information of the target power grid in the preset monitoring period are respectively recorded asGrid operation safety index for analyzing power equipment operation information of target grid in preset monitoring periodWhereinThe standard voltage, standard current and standard frequency of the power grid are respectively extracted from the database and used for the power equipment operation information of the target power grid in the preset monitoring period,The allowable difference value of the set voltage and the standard voltage, the allowable difference value of the current and the standard current and the allowable difference value of the frequency and the standard frequency are respectively.
It should be further noted 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 may be set to 0.01 volt, 0.01 amp, and 0.01 hz, respectively, which means that a deviation of one percent is allowed between the voltage and the standard voltage, between the current and the standard current, and between the frequency and the standard frequency.
The voltage, current and power factor of each power transmission device for extracting the power device operation information of the target power grid in the preset monitoring period are respectively recorded asWherein，For the number of each power transmission device,For the number of transmission devices, an electrical power transmission device operation safety index of electrical power device operation information of a target electrical power grid in a preset monitoring period is analyzedWhereinThe first power equipment operation information of the target power grid in the preset monitoring period extracted from the databaseStandard voltage, standard current and standard power factor of the individual power transmission devices,The allowable difference value of the set voltage and the standard voltage, the allowable difference value of the current and the standard current and the allowable difference value of the power factor and the standard power factor are respectively.
It should be further noted 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 may be set to 0.01 volt, 0.01 amp, and 0.01, respectively, meaning that a deviation of one percent is allowed between the voltage and the standard voltage, between the current and the standard current, and between the power factor and the standard power factor.
According to the invention, through analyzing the operation safety index of the operation information of the power equipment of the target power grid and judging the operation safety operation and maintenance requirements of the power equipment, the abnormal condition of the power equipment in operation can be found in time by operation and maintenance personnel, so that potential problems can be rapidly positioned, the accurate operation and maintenance can be realized, the efficiency and the accuracy of operation and maintenance work can be improved, the stable operation of the power grid can be ensured, the electricity utilization satisfaction of a user can be improved, the intelligent development of the power industry can be promoted, and the energy safety can be ensured.
The power dispatching information analysis module is used for acquiring the safety data parameters of the power dispatching information of the target power grid in the preset monitoring period, analyzing the safety index of the power dispatching information of the target power grid in the preset monitoring period and feeding back the safety index.
As a preferable practical example, the safety data parameters of the power schedule information of the target power grid in the set monitoring period include the power generation amount, the power consumption amount, the loss amount, and the storage amount.
The reason why the generated energy, the used energy, the lost energy and the stored energy are used as the safety data parameters of the power dispatching information of the target power grid in the set monitoring period is as follows: (1) The power generation is one of the core parameters in power dispatching, which directly determines the total amount of power that the grid can provide. The power supply capacity of the power grid can be known in real time through monitoring the generated energy, the power supply and demand balance is ensured, and the running risk of the power grid caused by insufficient or excessive power supply is prevented.
(2) The electricity consumption is an important index reflecting the load condition of the power grid. By monitoring the electricity consumption, the future power demand can be accurately predicted, and a scientific basis is provided for power dispatching. This helps to achieve dynamic balance of power supply and demand, ensuring stable operation of the grid.
(3) The loss reflects the loss of the grid during the transmission and distribution of power.
