基于全寿命周期成本管理的变电站配电装置比选研究

摘要

全寿命周期管理（LCC）设计要求按照统筹协调安全、效能和周期成本三者的关系，通过对设计方案进行比选，降低全寿命周期成本。介绍了全寿命周期成本的方法和计算模型，结合工程实际情况，基于全寿命周期成本设计，以资产全寿命周期成本作为重要经济性评价标准，对城市变电站中220 kV 配电装置按全户内气体绝缘组合电器设备（GIS）和户外混合气体绝缘组合电器设备（HGIS）进行方案比选，着重分析了220 kV配电装置的 LCC 构成，给出配电装置选择的依据，并提出建议。%Life Cycle Cost(LCC)design requirements in accordance with the overall coordination with the rela-tions between safety,efficiency and cycle cost.Through the comparison on design to reduce the total life cycle cost.The method and module of LCC were presented.According to the actual project and depending on LCC as an important economic evaluation standard,it was compared on the 220 kV power distribution units between indoor GIS & outdoor HGIS.Focused on the components of LCC of the 220 kV power distribution units,gave the basis for the selection of substation equipments and suggestions.
