摘　　要：变压器经济寿命的准确评估对电网安全及经济运行具有重要意义。首先构建变压器的故障模型,然后综合考虑变压器事故风险成本,变压器运行维护成本,变压器折旧成本,建立变压器的综合运行成本;在此基础上求取变压器年均综合运行成本的最小值,进而提出了变压器更新决策经济模型。通过实践算例证明了模型的准确性和有效性。Accurate assessment of transformer economic life is of great significance to the safety and economic operation of power network.The transformer fault model is introduced,then the comprehensive operating cost of transformer is proposed with considering transformer accident risk cost,transformer operation and maintenance cost and transformer depreciation cost.Based on this,the minimum value of the average comprehensive operation cost of the transformer is calculated.Then the economic model of transformer update decision is established.Case studies are taken on a real transformer to verify the model and results demonstrate the accuracy and effectiveness.
