基于风险分析的大型电力变压器经济寿命预测算法研究
Research on the Algorithm of Economic Life Forecast for power transformer Based on Risk Analysis
摘要
Abstract
The economic life of power transformer is determined by the year when the average annual cost is the lowest , And the average annual cost not only relates to the purchasing cost and the use-maintenance cost, also relates to the loss cause by transformer breakdown. Based on the model of economic life, the method of risk analysis has application in economic lift of power transformer, and an applied computational methods of power transformer fault risk is proposed, the maintenance costs and operation costs are analyzed, the new economic life model of power transformer is established. Combined with the maintenance data of old transformer, the forecast method of transformer economic life is verifed, Forecast results show that this method is satisfactory .关键词
