Xác định phân bố điện áp trên dây quấn của máy biến áp bằng phương pháp biến trạng thái

(Bản scan) The paper used the state variable method solved on Matlab Simulink software to determine the voltage distribution across the nodes at any time and the voltage distribution across the winding at the time the lightning pulse voltage reaches its maximum value. The paper has presented visual comparison results of the voltage distribution across two windings - continuous disk winding and interleaved disk winding. The results showed that the interleaved disk winding method has an initial voltage distribution close to that of a linearly stable distribution line. This means that the voltage distribution on the interleaved disk winding is more uniform than that on the continuous disk winding.
