【摘要】：电力工业是国民经济发展中最重要的基础能源产业之一,而变电站是电网建设中输电和配电的关键环节之一,在整个电网工程中是至关重要的。其工程质量水平将对整个电网安全、稳定运行产生直接影响,从而影响社会正常的生产生活,所以对变电站工程质量进行全面评价研究是非常必要的。本文以东胜西郊220KV变电站工程为例,构建了变电站工程质量评价指标体系和评价模型,对工程整体质量状况进行全面评价。具体研究内容主要分为以下五个部分。首先文章全面梳理了国内外关于变电站工程质量管理的相关文献,分析和总结了目前关于变电站工程质量管理的现状和研究方向。之后详细阐述了变电站工程质量管理的相关理论,并结合这些基础理论介绍了一般分析变电站工程质量管理的相关方法,经过比较后选择了德尔菲法及模糊综合评价相结合的方法。根据指标体系构建原则,首先通过文献统计,初步构建了东胜西郊220KV变电站工程质量管理评价指标体系,然后通过专家讨论构建了由3个一级指标和10个二级指标构成的东胜西郊220KV变电站工程质量管理评价指标体系,参照所构建的指标体系,全面介绍东胜西郊220KV变电站工程质量管理评价指标测度内容,以便专家进行打分。在介绍了东胜西郊220KV变电站的总体概况后,我们利用德尔菲法确定指标权重,并根据指标测度内容构建了指标隶属度评价矩阵;利用模糊综合评价法对东胜西郊220KV变电站工程质量管理进行评价,并分析了评价结果。
[Abstract]:Power industry is one of the most important basic energy industries in the development of national economy, and substation is one of the key links of transmission and distribution in power grid construction. The level of engineering quality will have a direct impact on the safety and stability of the whole power grid, thus affecting the normal production and life of the society. Therefore, it is very necessary to study the comprehensive evaluation of substation project quality. Taking 220KV substation project in the western suburb of Dongsheng as an example, this paper constructs the evaluation index system and evaluation model of substation engineering quality. The concrete research content is divided into the following five parts. Firstly, the paper comprehensively combs the relevant documents about substation engineering quality management at home and abroad. This paper analyzes and summarizes the current situation and research direction of substation engineering quality management, and then expounds the relevant theories of substation engineering quality management in detail. Combined with these basic theories, this paper introduces the relevant methods of general analysis of substation engineering quality management, and after comparison, chooses the method of combining Delphi method with fuzzy comprehensive evaluation. According to the principle of index system construction, firstly, through literature statistics, The evaluation index system of 220KV substation project quality management in the western suburb of Dongsheng is preliminarily constructed, and then the evaluation index system of 220KV substation project quality management in the western suburb of Dongsheng is constructed by expert discussion, which consists of 3 first-class indexes and 10 second-class indexes. Referring to the index system, this paper introduces comprehensively the evaluation index content of 220 KV substation project quality management in the western suburb of Dongsheng, so that experts can score it. After introducing the general situation of 220 KV substation in the western suburb of Dongsheng, The index weight is determined by Delphi method, and the evaluation matrix of index membership degree is constructed according to the content of index measure, and the quality management of 220KV substation in the western suburb of Dongsheng is evaluated by fuzzy comprehensive evaluation method, and the evaluation results are analyzed.
