Research On Quality Control Of Medium Voltage Power Network Engineering Construction Of County-level Power Supply Enterprises

With the rapid development of China economy, accelerating the pace of power development. Power grid construction as the main body of the electric power construction of our country, at present by the UHV construction and medium voltage power grid construction based. Long term since, the county power supply enterprises of medium voltage power grid construction project there has been a series of problems in the project settings not excellent, the design is not in place, the project management is not standard, the construction schedule delays, seriously affected the quality of construction. Therefore, the engineering construction of county-level power supply enterprises of medium voltage power network quality control has attracted more and more attention in power supply enterprises. How to improve the quality control level of county power supply enterprises of medium voltage power grid construction project will become a very important practical problems in electric power engineering quality control.The thesis takes the county power supply enterprises of medium voltage power grid construction project quality control as the object. First of all, based on a large amount of literature review, analyzes the domestic and foreign research present situation of medium voltage power network construction project quality management and control, presents some concepts related to quality, quality control. Secondly, the related theories and tools of project quality management and control by studying on current situation of county power supply enterprises of medium voltage power grid construction project quality control, aiming at the actual county power supply enterprise construction project of medium voltage power network engineering quality control, with "110k V SP 10 k V J station line construction project" as an example, analyzes the problems and reasons of the current existing. Once again, through investigation and literature, the introduction of comprehensive quality management and lifecycle quality management idea, constructing the whole life cycle of "five stages" quality management model, the implementation of quality control of full participation in the whole construction process in accordance with the mode of control quality of the whole process, and describes the quality control of each stage of the county power supply enterprises of medium voltage power grid construction project project life cycle strategy to improve the. Finally, by combining with practical cases, strategies to enhance the quality control of each stage of the specific analysis of the county level power supply enterprise of medium voltage power network construction project, to provide some ideas and help for other county power supply enterprises of medium voltage power grid construction project quality control.
