THE SIMULATION OF TRANSFORMER WINDING UNDER THE INFLUINCE OF VOLTAGE PULS BY MATLAB SIMULINK
232 KB
The synthesis of the algorithmic model of winding of a three-phase two-winding transformer by MATLAB Simulink has been considered. The original input signal in the form of a short duration pulse into components of the Fourier series has been decomposed. Calculated input voltage pulse has been presented us a sum of ten Fourier components and additional voltage supply. Additional voltage supply does not depend on skin effect and is a subtraction of input voltage pulse and ten Fourier components. In accordance with the superposition principle for each component of decomposition the transient process has been calculated as for the distributed circuit. Currents and voltages of separate turns and transformer winding as a hole have presented as algebraic sum of separate components. The functions of the state variables with input action as a probe pulse of short duration are given. According to a comparative analysis, the modeling characteristics obtained by us and the characteristics of a natural experiment have been coincided.
