Research On Quality Management Of UHV Transmission Line Engineering

"New infrastructure" includes seven major areas,including 5G infrastructure,ultra-high voltage,inter-city high-speed rail and inter-city Rail Transit,new energy vehicle charging piles,big data centers,artificial intelligence,and industrial internet,as one of the "new infrastructure",the most obvious characteristic of UHV is the high cost of the project,involving a wide range of fields,the quality of the project has a crucial impact on the national economic construction.The ability to optimise energy use is one of the characteristics of the High-voltage direct current#Back to back,making it particularly suitable for large energy bases.Our research on the quality management of High-voltage direct current#Back to back is of great significance for accumulating construction experience in UHV projects and improving the construction management level of domestic power projects.After studying a large number of documents and having a comprehensive understanding of the topic of the paper,this paper,combined with the previous research results,first systematically expounds the research background and significance,and then analyzes the relevant research documents at home and abroad,the related basic theories of construction quality management and its evaluation are carded out.Combined with the characteristics,principles and related quality influencing factors of UHV transmission line engineering quality management,through the basic work,the quality management goal plan,the quality control measure,the quality question and the countermeasure research,the Shanbei Hubei ± 800 KV special High-voltage direct current#Back to back project carries on the quality management research.Then establish the quality management evaluation system,and the use of integrated evaluation of the quality management of the mold and the results of the evaluation for the project to improve the direction of quality management and recommendations.
