Description

Technical Field

[0001] The invention belongs to the technical field of power engineering management and relates to a digital management platform for power engineering construction quality. Background Art

[0002] With the rapid development of information technology and the deepening of digital transformation, all walks of life are actively exploring how to use digital technology to improve management efficiency, optimize business processes, and ensure product quality. In the field of power engineering, construction quality is directly related to the safe and stable operation of the power grid and the reliability of energy supply. Therefore, efficient and accurate management of construction quality is particularly important.

[0003] In the prior art, there are some solutions related to the digital management of power engineering projects. For example, a comprehensive digital management method and management system for smart construction sites with publication number CN118246809A can quickly determine whether the current status meets the set threshold through real-time monitoring of real-time construction progress and power system performance; the construction control subsystem adjusts the real-time construction data, and the power system monitoring subsystem detects and troubleshoots the power system in real time, thereby realizing intelligent control of construction and power systems; by calculating the mean, weight and adjustment coefficient of historical construction data, as well as judging and adjusting real-time data, digital control of the entire construction process and power system operation is realized.

[0004] Although the above scheme proposes some solutions for the digital management of power engineering, there are still the following limitations, specifically: 1. When conducting quality inspections on power engineering projects, the existing technology is more inclined to focus on ground-surface installed equipment such as transformers and circuit breakers, and the inspection of buried equipment is relatively lacking. In addition, the existing technology does not perform differentiated inspections on the installation methods of the equipment when troubleshooting.

[0005] 2. Existing technologies are often tested based on fixed environmental conditions, while in actual operation, environmental erosion changes dynamically. Since the test conditions are fixed, it is impossible to fully simulate the various complex situations and dynamic changes in the actual operating environment. Therefore, there are often certain deviations in the test results. This deviation may lead to inaccurate evaluation of electrical equipment performance, which in turn affects the decision-making of equipment selection, installation and operation and maintenance. Summary of the invention

[0006] In view of this, in order to solve the problems raised in the above background technology, a digital management platform for power engineering construction quality is proposed.

[0007] The purpose of the present invention can be achieved by the following technical solutions: The present invention provides a digital management platform for the construction quality of power engineering, including an installation information acquisition module, which is used to list various electrical equipment of the power engineering, including various laying equipment and various buried equipment, and obtain the material characteristics and equipment application characteristics of each electrical equipment. Each electrical equipment is numbered .

[0009] The installation process quality detection module is used to detect the connection data of each electrical equipment and analyze the installation accuracy measurement coefficient of each electrical equipment.

[0010] Performance quality test module, used to test each electrical equipment and analyze the stability coefficient of each electrical equipment test run And the compliance coefficient of each electrical equipment test run .

[0011] The construction quality result feedback module is used to construct the construction quality discriminant vector of the power project, and then identify whether the construction quality of the power project meets the standards.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention identifies the correlation between the material properties of each laying equipment and each buried equipment and the condition tolerance indicators, and determines the installation accuracy tolerance of each electrical equipment accordingly, thereby providing clear standards and basis for quality inspection, thereby ensuring that different electrical equipment can fully adapt to various environmental conditions during the installation process.

[0013] (2) The present invention monitors the contact variables corresponding to the electrical equipment installed in welding and articulated ways, so as to timely discover the problems existing in the installation process of the electrical equipment with different installation methods. By analyzing the installation data indicators of each electrical equipment, the comprehensive control and management of the construction quality can be achieved, thereby improving the comprehensive controllability of the construction quality.

[0014] (3) The present invention detects the corresponding voltage fluctuation coefficient of each electrical device during the trial operation phase under the installation site conditions, and then uses a random function to generate a random transformation factor of the environmental erosion intensity within a specified transformation range, simulating a variety of erosion intensity conditions that are closer to the actual operating environment, thereby more accurately evaluating the voltage stability of electrical equipment under different environmental conditions and improving the accuracy and reliability of the evaluation. At the same time, by identifying the load conditions during the trial operation phase of the power project, various working conditions in actual operation can be simulated, thereby analyzing the compliance coefficient of the trial operation of each electrical equipment, and timely discovering possible problems of the equipment under specific load conditions, ensuring that the system can operate stably after formal commissioning.

[0015] (4) By quantifying the installation accuracy, environmental adaptability and layout rationality of electrical equipment, the present invention can more accurately evaluate each link in the construction process, reduce the subjectivity and uncertainty of human judgment, and thus improve the accuracy of construction quality assessment.
