Power transformer condition assessment based on AHP grey fixed-weight clustering
Liu Congfa · Dianli zidonghua shebei · 2013
Aiming at the incompleteness of operational condition information of power transformer,AHP(Analytic Hierarchy Process) method is applied to establish and quantify the level index of transformer condition assessment for its optimization.A grey fixed-weight clustering algorithm is introduced to classify the power transformer conditions and establish the whitening weight function of grey.The combination of AHP and grey fixed-weight clustering algorithm can assess the transformer condition more accurately,qualitatively and quantitatively.Practical case study shows that,the proposed method is reasonable and feasible.
