发电设备寿命周期费用影响因素的敏感性分析

阐述了发电设备全寿命周期费用（Life Cycle Cost，LCC）的基本理论及计算方法，针对发电设备LCC的影响因素之间存在的客观联系，假定因素之间相互独立，对其中某2个因素的变动幅度进行了一定的修正，使之更贴近实际。以某2×600MW火电机组为例，选取若干影响因素，求得其全寿命周期费用净现值。对目标净现值进行单因素和多因素敏感性分析，以寻找目标值与影响因素之间所存在的内在联系，为设备投资以及后期优化管理提供决策依据。

Research on Sensitivity of LCC Factors of Power Generation Equipment

This paper elaborates the basic theory and calculation method for life cycle cost （LCC） of power generation equipment. According to the intrinsic link among the various factors of LCC, a revision is made for the variation margin of the two main factors by assuming the mutual independence of various factors, which makes the analysis more realistic. Taking a 2 x 600 MW thermal power plant for example, several influence factors are selected to calculate the net present value of LCC. Single- and multi-factor sensitivity analysis is conducted on the target net present value so as to find out the internal relations between the target value and the influence factors and to provide a basis for decision-making for the equipment investment and optimization management.
