以变压器为例的电网主设备全生命周期成本分析方法研究
Research on LCC Analysis Method for Power Grid Primary Equipment with Example of Transformer

传统电网建设的成本管理方式，以控制采购成本为主。在电网长期运行环境下，追求安全、效能和成本三者的平衡关系，控制整体成本符合目标则更为重要。本文基于全生命周期管理理论，从电网主设备的成本归集和成本分析两个层面进行研究，以10 kV变压器作为典型案例，分析得出结论：购置费用和故障率是案例变压器全生命周期最主要的两项因素。
The cost management approach in traditional power grid construction primarily focuses on controlling procurement costs. However, in the long-term operational context of the power grid, achieving a balanced relationship between safety, efficiency, and cost becomes even more important. This study is based on the theory of lifecycle management and investigates the cost assignment and cost analysis of the power grid primary equipment. Taking a 10 kV transformer as a typical case, the analysis concludes that acquisition cost and failure rate are the two most significant factors throughout the life cycle of the transformer.
