Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0043] 1. Embodiment 1:

[0044] A power distribution cabinet simulation verification system according to a preferred embodiment of the present invention is as follows: Figure 1 As shown, including:

[0045] A simulation and modeling module 11, for creating a mathematical model of the switchboard and its components, simulating the electrical behavior of the switchboard under different working conditions, and generating simulation data;

[0046] Among them, the simulation and modeling module includes a display screen, electrical components, a model builder, a network topology analyzer, a simulation controller, a data communication module and a processor; the display screen, electrical components, a model builder, a network topology analyzer, a simulation controller and a data communication module are all connected to and controlled by the processor.

[0047] The data acquisition module 12 is used to continuously monitor the operating status of the power distribution cabinet and collect operating data packets of the power distribution cabinet in different states in real time;

[0048] Among them, the data acquisition module includes multiple sensors, a data acquisition device that converts analog data collected by multiple sensors into digital signals, and a signal conditioning circuit that amplifies, filters, isolates and converts sensor signals. In this embodiment, multiple sensors include voltage sensors, current sensors, temperature sensors, humidity sensors, etc. in the prior art; by using multiple sensors, different parameters of the power distribution cabinet (such as voltage, current, temperature, humidity, etc.) can be fully monitored to ensure that the operating status of various aspects of the power distribution cabinet is obtained. And multiple sensors can provide redundant data to increase the reliability of the system. Even if a sensor fails, other sensors can continue to work. The data acquisition device efficiently collects analog data from multiple sensors and converts them into digital signals, which are easier to be processed and analyzed by computers, and are convenient for subsequent data storage, transmission and analysis; digital signals have stronger anti-interference capabilities than analog signals, and can ensure the accuracy of data during transmission; making data integration and analysis more convenient and efficient.

[0049] The diagnosis and analysis module 13 is used to process and analyze the collected operation data packets to identify the operation trends and abnormal conditions of the power distribution cabinet; diagnose possible faults or potential problems of the power distribution cabinet based on historical data and artificial intelligence algorithms, and provide fault location;

[0050] The diagnosis and analysis module includes a data preprocessor for removing invalid, erroneous or abnormal data and converting the data to a uniform range, a fault detection unit for detecting anomalies by setting parameter thresholds, a central processing unit for executing diagnostic algorithms and analysis, and a report generator for generating diagnostic analysis reports. The analysis content includes fault detection results, analysis process and conclusions. The data preprocessor removes invalid, erroneous or abnormal data to ensure that subsequent analysis is based on accurate and effective information; the data preprocessor converts the data to a uniform range so that data from different sources and formats can be compared and analyzed, improving the availability of data. By setting parameter thresholds, the fault detection unit can quickly detect the abnormal state of the distribution cabinet, and can discover and handle the fault before it develops into a serious problem, reducing the risk of accidents; the central processing unit executes complex diagnostic algorithms to deeply analyze data, identify fault modes and potential problems; based on the results of algorithm analysis, it can also automatically make decisions or provide decision support, reducing reliance on manual experience. The report generated by the report generator provides a detailed process of fault detection and analysis, increasing the transparency of the system; and the report generator also provides written records for maintenance and fault handling, which is convenient for tracking and auditing; thus, the distribution cabinet can be managed more effectively and the overall system performance can be improved.

[0051] The verification and early warning module 14 verifies whether the actual performance of the power distribution cabinet meets the design standards and safety requirements based on the results of the diagnosis and analysis module; sets the safety threshold according to the design parameters and operation standards of the power distribution cabinet. When the monitored data exceeds the safety threshold, the system automatically alarms; and generates verification reports and early warning records at the same time, providing document support for maintenance decisions and accident investigations.

[0052] Among them, the verification and early warning module includes a verification engine for verifying the operating parameters of the distribution cabinet and matching the actual operating data with the preset rule data to determine whether the system is operating normally, and an alarm that is electrically connected to the verification engine and issues an alarm based on the abnormal signal issued by the verification engine. Verifying the consistency of the operating parameters of the distribution cabinet with the preset rule data through the verification engine can ensure that the system operates in accordance with the design standards and safety requirements; it can also prevent equipment failures or safety accidents caused by parameter deviations from the normal range through verification, and the verification process helps to ensure the reliability and stability of the distribution cabinet and reduce unexpected downtime. When the verification engine detects an abnormality, the alarm can immediately sound an alarm to remind the operator to take action, which helps to quickly respond to potential safety risks and prevent accidents.

[0053] The alarm can also reduce the need for manual monitoring, improve monitoring efficiency, and significantly improve the safety of the distribution cabinet system.

[0054] The simulation and verification system of the distribution cabinet is cleverly designed. By creating a mathematical model of the distribution cabinet and its components, the electrical behavior of the actual distribution cabinet can be simulated, thereby predicting its performance without a physical prototype. Simulating the electrical behavior under different working conditions helps to understand the performance of the distribution cabinet under various conditions. The data acquisition module monitors and collects operating data in real time to ensure the authenticity and timeliness of the data, which is crucial for subsequent analysis and diagnosis. The collection of data packets can reflect the performance of the distribution cabinet in different states and provide rich information resources for analysis. The collected data is processed and analyzed by the diagnosis and analysis module, which can identify the operating trends and abnormal conditions of the distribution cabinet, which helps to discover problems in advance. The use of historical data and artificial intelligence algorithms for fault diagnosis can improve the accuracy and efficiency of diagnosis, locate potential problems in a timely manner, and quickly identify the problem. The above design can help improve the overall performance and safety of the distribution cabinet, while reducing operating costs, and provide a strong guarantee for the stable operation of the power system.
