Abstract:

In order to supervise the quality of substation project construction more scientifically, comprehensively and objectively, quality supervision system and evaluation indicators of substation construction project were proposed. Based on the analytic hierarchy process with the characteristic of subjective estimation and the entropy weight method with objective quantitative calculation, the combined weight of index was given. Combined with expert evaluation method and fuzzy comprehensive evaluation method respectively, the combination weighting was used to evaluate the quality of substation construction project in order to determine whether the quality of power construction project was qualified or not. Taking the quality supervision of civil engineering in a 220 kV substation construction project in Hunan as an example, compared with the traditional method of quality surveillance, the method based on combined weights reflects the actual situation of engineering construction more objectively and accurately, meanwhile the results are more intuitive.

Key words: substation project construction, quality supervision system, combination weighting, expert scoring, fuzzy comprehensive evaluation
