全寿命周期成本理论在变电站非晶合金站用变压器选型中的应用

摘要

在电力行业中,为了降低变压器的损耗,经常选择低损耗且环保性能好的非晶合金变压器.然而由于非晶合金变压器初始投资成本高,在本文案例之前变电站站用变压器并无选用非晶合金变压器的案例.基于全寿命周期成本(LCC)理论,提出了非晶合金变压器和常规变压器全寿命周期对比分析方法,分析了站用变压器选用非晶合金变压器的可行性,并给出了容量选择的建议方案.%In order to reduce the loss of transformers in power industry,the amorphous alloy transformer with the advantages of low loss and good environmental performance is often selected.However,due to the high initial investment cost of amorphous alloy transformer, there is no application of amorphous alloy transformer in the station transformer before the case introduced in this paper.A comparative analysis method for the life cycle cost(LCC)of amorphous alloy transformers and conventional transformers is proposed.The feasibility of using amorphous alloy transformer for station transformer is analyzed,the proposal of capacity selection is proposed.
