Abstract


Construction supervision of the center of the work is the goal of the project control , and that the investment of the project , progress, quality targets control . The quality of water conservancy and hydropower project , especially large-scale hydropower project quality is an essential part . 4 # Lijiaxia hydropower generators , evaporative cooling , quality issues are particularly important . # 4 generator sets and before three different machines on is that the generator uses evaporative cooling , so the quality of the installation of the stator assembly line 4 # generator whole units directly related to the quality of the installation . Quality control as a primary objective , the application of fuzzy theory , the mathematical model of the fuzzy evaluation and fuzzy comprehensive evaluation . This article is mainly to do the following tasks : ( 1 ) A summary of the development process of the establishment of the supervision system in China , supervising engineer in the construction process of the project , how to carry out supervision work . ( 2 ) the theory of fuzzy mathematics in various fields , in particular, is widely used in engineering construction were analyzed and summarized . ③ This paper for the first time will use fuzzy theory offline quality control process in the Lijiaxia Hydropower 4 # generator stator , quality control for large-scale water conservancy and hydropower project , has strong theoretical significance and practical value . For future hydropower construction supervision , provides a new way of thinking and methods . ④ fuzzy theory Stator Winding of the key installation quality control of the whole process is to establish the factor set and weight set . Factors affect the quality of the installation of the Stator Winding of the whole process to concentrate the most important factors the positioning bars downline it in the weight concentrated weights . Installation quality control of the entire process off the assembly line in the generator stator , seize the positioning bars offline key processes fuzzy comprehensive evaluation of the quality of the Stator Winding fuzzy theory , the result is excellent . The the ⑤ Lijiaxia Hydropower Station 4 # generator running year running results show that : the cooling temperature for the determination of sub - bars meet the design requirements , verify the reasonableness of the generator stator downline fuzzy comprehensive evaluation results .
