摘　　要：将全寿命周期成本(life cycle cost,LCC)理论应用于输变电一次主设备准入决策有利于电力企业资源配置优化。基于此,分析了传统LCC模型数据难获取、难处理、难匹配的应用局限,结合电力企业资产管理实际提出了改进的LCC应用模型。为优化资产成本效益,采用设备最优准入年限概念和全资产周期成本最优理念,建立单设备年均LCC准入模型和输变电一次主设备分步准入模型。最后,通过算例验证了传统准入模型是所提出模型的一种特例,而基于LCC的分步准入模型可为电力企业输变电一次主设备大修与技改准入提供决策依据。It is beneficial for electric power enterprises to optimize resource allocation to apply life cycle cost （LCC）to pri-mary main equipment for power transmission and transformation.Therefore,the paper analyzes limitations in application of LCC model such as difficulties in data access,process and match;in addition,it presents the improved LCC model in ac-cordance with asset management practice in electric power companies.To optimize cost benefit of asset,optimal equipment access time limit and whole asset cycle cost are applied to establish annual LCC access model of single equipment and step ac-cess model of primary main equipment for power transmission and transformation.Finally,the paper proves that traditional access mode is just a special case of the mentioned model while the step access model based on LCC can provide decision-making reference for primary main equipment overhaul in electric power companies and technical renovation access.
