电网企业将LCC理论应用作为提高设备资产效率和质量的有效手段,亟需解决LCC应用中的模型计算和评价体系问题.本文通过构建电网企业资产全寿命周期管理机制,建立了电力设备的LCC的计算模型和方法,采用基于模糊数学中的模糊隶属度方法,改进了技改和大修项目分摊到多个设备资产分摊方法,提出了电力设备的LCC评价模型和评价体系,并成功应用于中国南方电网广州地区的设备和项目管理中,达到了设备资产的运营质量和效率优化决策目标.“,”Life-cycle cost (LCC) theory can be effectively applied to improve the efficiency and quality of power plant equipment and asset management. However, specific aspects of the LCC calculation and evaluation model require further research for practical application. This paper proposes an LCC assessment model for the management of electric power plant equipment during its service life. A membership function method based on fuzzy logic is used to improve the allocation of modernization and overhaul projects to multiple equipment assets. An LCC assessment model and evaluation system for power equipment are proposed and successfully applied to the equipment and project management of a Guangzhou power plant in the China Southern Power Grid, providing a decision-making mechanism that facilitates efficient operation and optimal utilization of power plant equipment and assets.
