根据《火力发电厂与变电站设计防火标准》(GB 50229-2019)中变电站防火内容,2019年国家电网有限公司对通用设计就消防部分进行了修编,形成了最新的通用设计成果,对变电站消防有了新的规定和要求.为满足最新设计标准,大量工程要进行消防改造,但技改造价分析大纲未包含消防改造内容.通过分析消防改造的分类、造价等,明确各消防改造工程单位造价和投资控制重点,意义重大.

With the growing market demand for power, power supply enterprises in various regions are constantly increasing the investment in power grid construction projects. Taking the asset life-cycle management as the research object, this paper proposes to use the random forest method to rank the importance of the influencing factors of the equipment life-cycle cost, identify the impact degree of the influencing factors of HGIS/GIS equipment life-cycle cost, and analyze and find the important indicators and their impact degree combined with Pearson correlation. It provides a basis for reducing unnecessary loss caused by risk factors.

With the rapid development of economy and society, power grid needs the optimal comprehensive benefit of integrating performance, cost and risk control. To pay attention to the life-cycle management of assets, adopt the TOPSIS-AISM combined model, introduce the AISM method, visually present the ranking results of TOPSIS, combine with Pearson correlation analysis, find out the influencing factors of the indicators, calculate the impact degree, and perform the advantages and advantages grading, which is in line with the requirements of the sustainable development direction of the enterprise. It can effectively reduce the overall operating cost of equipment assets and create greater social and economic benefits for enterprises.
