Abstract
Description
Technical Field
[0001] This invention relates to a review method, and more particularly to an intelligent review method for preliminary design schemes of power engineering projects. Background Technology
[0002] In the field of power engineering, preliminary design review is a core part of the early stages of a project, playing a crucial role in ensuring the quality of subsequent construction, effectively controlling project investment, and guaranteeing the safe and reliable operation of the power grid. The preliminary design documents for modern power transmission and transformation projects are extensive and complex, involving multiple technical fields such as primary electrical systems, secondary electrical systems, communications, civil engineering, transmission lines, environmental protection and soil and water conservation, and technical economics. Review experts need to conduct a comprehensive and in-depth evaluation of the design schemes within a short period of time, based on a vast amount of constantly updated national and industry mandatory standards, internal company standards, general design atlases, typical design cases, and rich historical review opinions and engineering data.
[0003] Traditional review models rely heavily on experts' personal experience and manual operations, facing significant challenges. Firstly, there is information overload and difficulty in knowledge retrieval; the knowledge sources needed for review are scattered across hundreds or even thousands of documents, requiring experts to spend considerable time manually reviewing, comparing, and verifying, resulting in extremely low efficiency. Secondly, the process is cumbersome, creating a significant efficiency bottleneck: from receiving design documents and checking their structure and the completeness of drawing labels, to verifying the compliance and rationality of technical parameters and economic indicators item by item, and then summarizing opinions from various disciplines to form a formal review report and meeting minutes, the entire process is highly dependent on manual labor, time-consuming, and labor-intensive, becoming a major bottleneck restricting the improvement of review efficiency.
[0004] Therefore, in order to solve the above-mentioned technical problems, it is urgent to propose a new technical approach. Summary of the Invention
[0005] In view of this, the purpose of this invention is to provide an intelligent review method for preliminary design schemes of power engineering projects. By pre-constructing a corresponding normative knowledge base, and then parsing the preliminary design scheme of the power engineering project, text matching is performed. The matched text information is then input into a trained large language model for normative prediction, thereby effectively improving the efficiency of reviewing preliminary design schemes of power engineering projects. Furthermore, after the review by the large language model, logical and over-design judgments are performed, thereby further improving the accuracy of the review results.
