Abstract：Transformer is one of the most important electrical equipments in power system .With the characteristic of leakage inductance change caused by winding deformation ,on-line parameters identification of transformer winding is put for-ward higher requirements .In this paper ,double winding transformer modelis simulated and the least square method is adopt-ed to realize accurate on-line identification of the transformer parameters .The simple system is simulated by Matlab/SIM U-LINK and the resultis shows that the algorithm is not affected by the load factor and power factor .The algorithm can identify the transformer winding parameters accurately and achieve on-line monitoring .
