基于物元可拓的电网技改项目后评价研究

Research on post-evaluation of power grid technological transformation project based on matter-element extension

针对电网技改项目评价方法单一的缺陷,打破原有评价方法的束缚以及规避以往技改项目后评价法受专家主观影响较大的问题,本文引入了物元可拓评价方法,搭建了基于全寿命周期的技改项目后评价模型,从项目前期工作、项目实施准备、项目实施管理、结决算管理、档案管理和项目投资控制以及项目运营绩效7个方面进行深入研究。结合苏州500kV石牌变综自改造和保护更换工程进行综合评价和分析,验证了所建模型的实用性和有效性,为日后指导技改项目后评价工作和加强技改管理工作提供理论和技术支持。

In view of the defect of single evaluation method for power grid technological transformation projects,the restriction of the original evaluation method is broken and the problem that the former post-evaluation method for technological transformation projects is greatly influenced by experts'subjectivity is avoided.In this paper,the matter-element extension evaluation method is introduced,and the post-evaluation model of technological transformation project based on the whole life cycle is established.The in-depth research is carried out from seven aspects of the project's preliminary work,project implementation preparation,project implementation management,final accounts management,file management,project investment control and project operation performance.Based on the comprehensive evaluation and analysis of the self-renovation and protection and replacement project of Suzhou 500kV Shipai substation,the practicability and effectiveness of the model are verified,which provides theoretical and technical support for guiding the post-evaluation work of technological transformation projects and strengthening technological transformation management work in the future.
