风电机组的低电压穿越 LVRT
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。
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.
风电场低电压穿越能力对电力系统的稳定性有着重要影响。
The low voltage ride-through (LVRT) capability of wind farms has a great impact on the power system stability.
随着风力发电在电网中的比例日益增加，电网对风电机组的要求也越来越高，低电压穿越技术(LVRT)就是其中一项重要指标。
With the proportion increasing of wind power generation in power grid, the power grid demand for increasingly high to wind turbine. Low-voltage through technology (LVRT) is one important indicator.
