输配电线路全生命周期可靠性成本研究

Research on Life-Cycle Reliability Costs of Transmission Lines

摘要: 本文对不同的输配电线型的可靠性成本分别进行了LCC计算和比较分析，说明了要减少输配电系统的全寿命周期成本费用，降低其一次投资成本是重要环节，但是一味降低投资成本IC来减少全寿命周期的成本费用并不可取，根据线路在应全生命周期不同阶段的费用和可靠性综合来考虑，选择利于长期运行的设备。

Abstract: The article gives calculation and comparison analysis on life-cycle reliability costs of different transmission lines, shows what is related to the lost on system of full life cycle costs, and reducing its once investment cost is an important link. But blindly reducing investment cost to reduce full life-cycle costs is not desirable, it’s better to select long-life equipment according to the different stage of costs and reliability.
