مدل سازی ترانسفورماتور توربین بادی برای تجزیه و تحلیل اضافه ولتاژهای رزونانس

The measurements and modeling results show that all winding designs have a resonant frequency around 800 kHz for the transferred voltage to LV terminal. Disc winding shows the lowest amplitude of the transferred overvoltages (6 p.u.). The layer winding, also has a resonance at 1.6 MHz with an even higher transferred overvoltage (80 p.u.). The frequency response of the pancake winding has characteristics of both disc and layer windings. In spite of having the lowest transferred overvoltage peak, the disc winding has many additional resonant frequencies in the range of 100 kHz–1 MHz. This could excite resonances in other parts of the winding. Consequently, pancake winding designs might be the most promising to minimize resonance situations.
