| 摘 要： | 通过计算变流器直流环节的电容量和纹波电流,选取合适的薄膜电容器应用于风电变流器直流环节,取代铝电解电容器。利用Matlab仿真软件,使用改进的控制策略,验证了最小电容量选取原则的可行性。将此原则应用于2 MW风电用双馈变流器直流环节薄膜电容器的选型,取得了较为理想的效果。 |

| Abstract: | An appropriate film capacitor was selected to take the place of aluminum electrolytic capacitor apply in DC-link of the PWM converter system through the calculation of capacitance and ripple current.The feasibility of the principle of selecting the minimum capacitance is proven by using improved control strategy in Matlab simulation.The film capacitor,which was selected based on the selection principle performed well in DC-link of 2MW DFIG system. |
| Keywords: | wind power PWM DC-Link film capacitor capacitance ripple current |
