摘　　要：为指导测控单元故障后的技改方案选择,优化其全生命周期成本,在建立厂站测控单元的LCC故障损失费用模型时,基于串联系统概率乘法理论,梳理了整机故障概率与配件故障概率的估算关系,提出考虑数据故障恢复时间和数据重要性的数据损失费估算模型,并以广西某变电站某开关的测控单元为例,分析了该设备投运后各年度不同技改方案的费用年值,验证了计及技改方案的测控单元LCC模型的可行性。In order to guide and control the technical reform scheme after the unit fault and to optimize the whole life cycle cost,it chooses the time of the estimation model.It is proposed considering the importance of data loss.Based on the series system probability theory,it estimates the relationship between the multiplication machine failure probability and the failure probability of the parts.It is based on LLC fault cost model of station control unit.Taking the control unit of a switch in Guangxi some substation as an example,it analyzes the annual cost of the technical transformation scheme of the equipment being used each year,and verifies the feasibility of the LCC model and the control unit of the technical scheme.
