具有增强短路电流的新型功率模块为构网型风力发电机组低电压穿越带来的潜力与挑战

Improving the short-circuit current capability of converters can directly enhance the low-voltage ride-through (LVRT) performance of doubly-fed induction generator (DFIG) based wind turbine systems (WTS). Previously, this approach was limited by power semiconductor modules and costs. Recent advances in materials and modulation strategies have greatly boosted their short-term overcurrent capability...
