| 摘 要： | 风电场的电网电压骤升故障会造成双馈风力发电机定子绕组中产生定子磁链的暂态直流分量,甚至引起比电网电压跌落更强的双馈电机定、转子电流和电磁转矩的冲击。为研究双馈风力发电机的高电压穿越(HVRT)特性,首先分析了电网电压骤升的产生机理和电网电压骤升及恢复过程中双馈电机电磁过渡过程,讨论了撬棒电阻对HVRT的影响,并与低电压穿越(LVRT)情况做了对比。

| 关 键 词： | 双馈电机 高电压穿越 撬棒电路 |

| Abstract: | Grid voltage swell will cause DC flux component in the DFIG stator winding,creating more serious stator, rotor curent and torque oscillation compared with voltage dip. This paper analysis the causes the grid voltage swell, dynamic behavior during voltage swell and recovery, the crowbar effect on HVRT and compare it with LVRT. |
