| 摘 要： | 直驱型风力发电系统采用三相不控整流桥与带有大容量电容器的电压源电流控制型逆变器并网发电,电能变换电路向永磁同步发电机中注入了大量低频谐波,增加了系统损耗,减少了系统功率容量。提出了一种将两组Boost电路并联,并采用单周期技术加以控制的方案。仿真结果表明,该方案实现了对永磁同步发电机的输出进行功率因数校正、降低发电机电流的谐波含量、提高系统功率容量的目标,从而验证了该方案的可行性和正确性。

| Abstract: | Direct-drive wind power system had been using three-phase bridge rectifier（BR） with a bulky capacitor associated with voltage source current controlled inverter（VS-CSI）,the inverter introduced lots of low frequency harmonic into the PMSG and consequently increased the total loss in it and decreased the power capability of the system.A scheme that two Boost circuits were paralleled and was controlled by OCC（one-cycle control） was presented.Simulation results indicated that this scheme could correct the output power factor of the PMSG,decrease the current harmonic content of the PMSG,and increase the power capability of the system.Subsequently it verfied that the proposed scheme was feasible and correct. |
