Research on Calculating Leakage Inductance of Power Transformer and its Application to Winding Deformation Analysis
Transformers are required to demonstrate the operative ability by analysis of electromagnetic characteristic and parameters calculation, and it is difficult to describe the winding deformation quantitatively. Based on finite element method (FEM), the model comprising iron-core and windings is shown. The electromagnetic characteristic is analyzed by coupled field-circuit, the leakage inductance parameters of power transformer are calculated by energy method in this paper. Depending on the relations that the value of leakage inductance relies on dimensions and positions of transformer windings, the simulation models of different deformation are described by changing winding physical dimension and the values of leakage inductance in these conditions are presented by the software ANSYS. The test results of ANSYS simulation indicate that the accuracy of proposed algorithms is high and the change of parameter can successfully detect if and how the windings have occured deformation.
