In the models , the iron core nonlinearly of the traction transformer and the magnetic hysteresis effect without the b - h curve are considered . having tested by digital simulation , the winding parameter has not changed in the state of external fault or magnetizing inrush etc . but the winding parameter has obviously changed in state of inter fault or inter - turn fault . ( 3 ) the rules three phases converted to two phases of traction transformer in electric railways are developed in this paper （ 3 ）利用牽引變壓器磁鏈平衡方程，建立了基于系統辨識理論的雙繞組單相接線牽引變壓器、阻抗匹配平衡牽引變壓器及scott （斯科特）接線牽引變壓器的“灰箱”模型，該模型考慮了牽引變壓器鐵芯非線性和磁滯效應，但又不直接反映在模型中，并且無需鐵芯的b - h曲線數據。 |
