Transformer price evaluation method based on equipment composition

The invention relates to a transformer price evaluation method based on equipment composition. The method comprises the following steps: estimating the costs of transformers; performing multiple regression on the quantity demanded, concentration ratio and bidding strategy data of the transformers, judging the goodness-of-fit through correlation indexes, index goodness-of-fit and determination indexes, and acquiring a functional relationship among profit, transformer demand, concentration ratio and bidding strategy through significance testing; sequencing dispersion degrees of random price components of a certain type of transformers at a price historical data point, and eliminating individual sample points with high dispersion degrees, so as to obtain a price fluctuation interval pss and further obtain a transformer price evaluation model; evaluating transformer prices according to the transformer price evaluation model, so as to reduce the equipment procurement cost and engineering investment risk. 本发明涉及种基于设
