【Abstract】 Transformer windings are usually subject to faults.Based on the theory of strong tracking filters,an online fault diagnosis method for transformers is given by combining state estimation and parameter identification.Computer simulations show that this method can effectively determine the kind of faults and the parameter related to the faults.In addition,the parameter identification remains accurate when the fault happens.更多还原
