Abstract

The short-circuit-reactance method is one of effective measures to detect the transformer′s winding deformation.Online detecting the short-circuit-reactance has a great significance in winding′s state.In order to realize on-line monitoring the transformer winding

based on a model transformer

an on-line identification algorithm for transformer leakage inductance is proposed with recursive least-square algorithm.The measuring system errors are analyzed and calculated

a method like fuzzy neural network is put forward to compensating error of PT and CT.Comparing the online and offline measuring value

it shows that the measuring system is satisfactory for detecting short-circuit reactance variations with high degree of accuracy and good stability

and the running condition of transformer will not influence the results

and it can be used for detecting deformation of the transformer windings.
