本文首先阐述了国家电网工程相关科学理论及变电站优质工程评选方法和政策,其次系统地提出了变电站优质工程评定指标体系,然后根据G1权重确定理论和属性测度区间识别理论建立变电站优质工程评定模型,最后应用于110k V科盛变电站工程,结果表明本文所采用的方法能够全面和客观地对变电站进行优质工程评定。 This paper first describes the relevant theories of State Grid Engineering and substation quality projects selection methods and policies, followed by a systematic evaluation of substation quality project index system, and then based on the G1 weight determination theory and property measurement interval identification theory to establish substation quality project assessment model, Finally, it is applied to 110k V Kesheng Substation Project. The results show that the method adopted in this paper can comprehensively and objectively evaluate the quality of the substation.
