Background Art

[0002] As the scale of power systems continues to expand and power equipment becomes increasingly complex, traditional power monitoring methods can no longer meet the requirements for real-time, comprehensive, and accurate monitoring of power systems. Therefore, there is an urgent need for a method that can collect, process, and analyze power operation status data in real time and analyze the data to improve monitoring accuracy. The following is the current status of this technology:

[0003] Data collection and monitoring: Traditional power system monitoring relies on various sensors and monitoring equipment, including voltage sensors, current sensors, etc., to collect operating parameters and environmental conditions of power facilities. These devices transmit data to the central monitoring system through wired or wireless communication. As the complexity and scale of power systems increase, the requirements for the accuracy and real-time performance of data collection are also getting higher and higher.

[0004] Data processing and analysis: Traditional monitoring systems use simple data storage and analysis methods, including threshold alarms and simple statistical analysis. These methods are inefficient in processing large amounts of data and have difficulty discovering potential failure modes and abnormal behaviors.

[0005] Remote control and user interaction: Traditional monitoring systems mostly provide basic data display and simple control functions. The user interface is relatively simple and lacks intuitiveness and interactivity.

[0006] Algorithm optimization: Traditional optimization algorithms have problems such as slow convergence and easy falling into local optimality when processing complex power system data.

[0007] Environmental adaptability: With the continuous changes in the operating environment of the power system, such as fluctuations in grid load and changes in weather conditions, higher requirements are placed on the environmental adaptability of the monitoring system, which needs to better adapt to different operating conditions. Summary of the invention

[0008] In view of the above problems, the purpose of the present invention is to provide an improved real-time monitoring system for power operation status, aiming to obtain more accurate data through an improved grey wolf algorithm, introducing an environmental adaptability mechanism and dynamically adjusting the search range.

[0009] The technical solution of the present invention is: the improved real-time monitoring system for electric power operation status described in the present invention comprises an electric power data acquisition perception layer, a data processing platform layer and a user application layer;

[0010] One side of the power data acquisition and perception layer is connected to one side of the data processing platform layer via the network layer for data transmission;

[0011] The data processing platform layer is connected to the power data acquisition layer and the user application layer respectively to receive data and transmit data processing results, and respond to user adjustment instructions;

[0012] The user application layer is connected to the data processing platform layer and the power data acquisition perception layer respectively, and is used to display data processing results and issue execution instructions respectively.

[0013] Furthermore, the power data acquisition perception layer is responsible for data acquisition, including the deployment of various intelligent sensors and monitoring equipment, including voltage sensors, current sensors, power factor sensors, and frequency sensors, to monitor the operating parameters and environmental conditions of the distribution facilities in real time, and configure corresponding communication parameters according to the communication protocol of the sensor and the microcontroller, including mode, direction, data size, polarity, clock phase, and baud rate, and collect data through the cooperation of the two.

[0014] Furthermore, the user application layer helps users view data that has been accurately processed by the data processing platform layer through the user interface, including real-time monitoring information, historical data, and analysis reports; users provide feedback on the monitoring results, and these feedbacks are used to optimize the performance of the monitoring system; users issue control instructions based on the monitoring results, including adjusting device parameters, starting or stopping certain devices; the control instructions issued by the user are transmitted to the power data acquisition perception layer through the network layer, and the embedded microcontroller executes these instructions to achieve remote control of the power system.

[0015] Furthermore, the data processing platform layer manages data through a database, and stores the data received from the perception layer in the database to facilitate subsequent processing and analysis; the monitoring software reads data from the database for further intelligent analysis; the improved Gray Wolf optimization algorithm is used to analyze the data to improve monitoring accuracy, identify abnormal patterns, and perform fault diagnosis; then, based on the analysis results of the improved Gray Wolf optimization algorithm, it is determined whether the state of the power system is normal; if the result is abnormal, the system will trigger an alarm mechanism and transmit the fault diagnosis result to the user application layer; if the result is normal, the system will transmit the processed data to the user application layer for the user to view and further analyze.

[0016] Furthermore, the data processing platform layer is a method for optimizing the parameters of the real-time monitoring system of the power operation status based on the improved grey wolf optimization algorithm, and the specific steps are as follows:

[0017] Step (1): Initialize the wolf pack, including the positions of alpha (α), beta (β), and delta (δ) wolves;

[0018] Step (2): Evaluate the fitness of each wolf;

[0019] Step (3): Update the positions of α, β, and δ;

[0020] Step (4): Update the position of each wolf in the wolf pack;

[0021] Step (5): Check the termination condition, reaching the maximum number of iterations or the system reaching the preset accuracy standard.

[0022] Furthermore, in steps (1)-(3), the wolf pack is initialized, including the positions of α, β, δ and other wolves, the fitness of each wolf is evaluated, and the positions of α, β, δ are updated; the specific process is as follows:

[0023] Assume that the wolf pack consists of N wolves, and the position of each wolf is X i Randomly initialize in the search space as follows:

[0024] X i =X min +rand()·(X max -X min )

[0025] In the formula, the position X of each wolf is i are the power system parameters, including the initial values ​​of voltage, current, power factor and frequency; rand() is a random number generation function, X min and X max are the minimum and maximum values ​​of these parameter ranges, respectively;

[0026] After initialization, the algorithm evaluates the fitness F of each wolf based on its position in the pack. i , which is related to the objective function of the optimization problem; the algorithm determines the positions of α, β, and δ wolves in the wolf pack according to their fitness, representing the optimal, suboptimal, and third-optimal solutions currently found;

[0027] Calculated according to power system parameters, it is defined by the inverse of monitoring accuracy; as follows:

[0028]

[0029] In the formula, F i The operating efficiency and stability of the power system are related. Error (Xi) is the total error of the system under the current parameter settings, including voltage deviation and frequency deviation. The operating efficiency and stability of the power system are related.i It is inversely proportional to the total error Error(Xi) of the system under the current parameter settings. The smaller the total error of the system under the current parameter settings, the higher the correlation between the operating efficiency and stability of the power system, and the higher the accuracy of the monitored data;

[0030] F α =min(F i ),F β =min(F i ,i≠α),F δ =min(F i ,i≠α,β)

[0031] According to the correlation between the operating efficiency and stability of the power system, a more accurate parameter configuration is selected as α, β, and δ, and the system is guided on how to adjust the power system parameters to improve the accuracy of the system data.

[0032] Furthermore, in steps (4)-(5), the position of each wolf in the wolf pack is updated and the termination condition is checked, such as reaching the maximum number of iterations or the fitness meets the requirements; the specific process is as follows:

[0033] Update the position of each wolf, C adj , C is the coefficient vector, t is the current iteration number, and T is the maximum iteration number; as follows:

[0034]

[0035] X i =X α -C adj ·(C1·X α -X i )+C adj ·(C2·X β -X i )+C adj ·(C3·X δ -X i )

[0036] In the formula, C adj , C1, C2, and C3 are adjustment coefficients to update power system parameters; A affects the adjustment of power system parameters, C1, C2, and C3 control the power system parameters to more accurate voltage, current, power factor, and frequency;

[0037] Update the speed of the wolf pack V i , increase the global search capability of the algorithm, as follows:

[0038] V i =w·V i +A·(X α -X i)+B·(X β -X i )+C·(X δ -X i ))

[0039] Where, speed V i is the rate of parameter adjustment, the system responds quickly and adjusts its parameters to adapt to grid changes; w is the inertia weight, B is another coefficient vector;

[0040] F i <F α , then X α =X i

[0041] If the new parameter configuration provides better performance, these parameters become the new alpha (α);

[0042] t ≥ T or F α ≤threshold

[0043] If the maximum number of iterations T is reached or the system reaches the preset accuracy standard, accurate data is obtained and the iteration stops.

[0044] Furthermore, the gray wolf optimization algorithm is improved by introducing an environmental adaptability mechanism and dynamically adjusting the search range to obtain more accurate data. The specific process is as follows:

[0045] After each iteration, an environmental adaptability assessment step is added. This step will evaluate the relationship between the current power grid operation status and environmental changes, and adjust the wolf pack's search strategy according to these changes; by introducing an environmental adaptability coefficient, the coefficient is dynamically adjusted according to the degree of matching between the power grid operation status and environmental changes, so as to guide the wolf pack to search for the optimal solution more effectively.

[0046] The calculation formula of environmental adaptability coefficient EAC is as follows:

[0047]

[0048] In the formula, E current Indicates the current power grid operation efficiency, E avg Represents the average historical grid operation efficiency, S current Indicates the current grid stability, S avg Represents the historical average value of grid stability;

T is the time range of historical data, Ecurrent(t) is the current grid operation efficiency at time t, I i is the current value of the ith monitoring point, I ref is the reference current value, P j is the power factor value of the jth monitoring point, P ref is the reference power factor value, n and m are the number of current and power factor monitoring points, respectively, T is the time range of historical data, S current (t) is the current grid stability at time t;

[0051] The adjustment formula of the search range SR is as follows:

[0052]

[0053] In the formula, SR represents the search range, SR base represents the basic search range, EAC represents the environmental adaptability coefficient, C adj represents the adjustment factor;

[0054]

[0055] Where n and m are the number of voltage and frequency monitoring points, respectively, and p and q are the number of current and power factor monitoring points, respectively;

[0056] According to the environmental adaptability coefficient, the search range SR of the wolf pack is dynamically adjusted; when the environmental adaptability coefficient EAC is high, the search range SR is narrowed to conduct a more detailed search; when the environmental adaptability coefficient EAC is low, the search range SR is expanded to increase the globality of the search.

[0057] Furthermore, the improved gray wolf optimization algorithm is used to monitor the operation status of the power operation status real-time monitoring system, and improve the monitoring accuracy of voltage, current, power factor and frequency. The specific steps are as follows:

[0058] Step 1: Power system parameters, including initial values ​​of voltage, current, power factor and frequency;

[0059] Step 2: Evaluate the operational efficiency and stability of the power system;

[0060] Step 3: Update α, β, δ;

[0061] Step 4: Update the position of each wolf in the wolf pack;

[0062] Step 5: Check the termination condition;

[0063] If Fi <F α , then X α =X i ,The system has not reached the preset accuracy standard, and continues to iterate;

[0064] If t ≥ T or F α ≤threshold, the maximum number of iterations is reached or the system reaches the preset accuracy standard, and the iteration is terminated.

[0065] The beneficial effects of the present invention are as follows: 1. By introducing the improved gray wolf optimization algorithm, the system can significantly improve the monitoring accuracy of the power operation status, effectively identify abnormal modes and perform fault diagnosis, and improve the operation efficiency and stability of the power system; 2.
