Calculation of Leakage Magnetic Field and Short-Circuit Impedance of Power Transformer

Abstract:

The leakage magnetic field and equivalent circuit model of OLTC double-winding power transformer has been established by electromagnetic field Finite Element analysis software. The method of field-circuit coupled method has been used to calculate its magnetic field leakage, the short circuit impedance obtained by the calculation of formula and compared with the experimental data. At the same time, based on the calculation method for the Visual Basic language as a tool for MAGNET software for secondary development, obtain the software to calculate the short-circuit impedance of power transformer simulation software, and is verified by using the typical products, proves the validity of this software.
