By adding damp load at DC-side of the converter, redundant energy at DC-side during grid faults will be consumed, therefore the operating of wind turbine will not be influenced by grid voltage sags.
为增强直驱型变速恒频风电系统的低电压穿越能力，采取了变流器直流侧增加卸荷负载以在故障时消耗掉直流侧多余的能量，使风电机组的正常运行基本不受电压跌落影响的应对措施。
In this paper, soft startup and impact suppression techniques are proposed to guarantee no voltage overshoots or sags in DC bus during startup and grid connection dynamic processes.
