Harmonic study of Le Blanc transformer for Taiwan railway electrification system
暂无分享,去创建一个
By measuring the harmonic current of Le Blanc transformer in Taiwan railway system's substation, this study elucidates how the Le Blanc transformer of Taiwan railway reduces supply capacity due to supply of power to the trolley (nonlinear load). How to improve the harmonic current in the point-of-common-coupling (PCC) after adding the double tuned filter in the load side is also described.
