Abstract
The life cycle cost (LCC) of power transformers is the main factor to be considered in the process of investment selection, and there are many uncertain factors in the life cycle cost assessment process of power transformers. In this paper, the blind number theory is introduced into the life cycle cost analysis of power transformers and build a mathematical model. The model includes initial investment cost, operation and maintenance cost, loss cost, environmental cost, failure cost, and decommissioning disposal cost of the power transformer. The life cycle cost of power transformers is analyzed, which provides a reference for power transformer selection. The selection result can not only calculate the blind number expectation value of the life cycle cost of the power transformer, but also obtain the possible distribution interval of different cost and the corresponding credibility information, improve the estimation result and the rationality of power transformer selection.
