| 摘 要： | 应用DIGSILENT软件,建立了双馈异步风力发电机组(DFIG)的并网模型,在三相电压不平衡工况下对其进行了理论分析仿真,在这种非正常工况下双馈异步风力发电机组的定子端会产生很大的负序分量。在此基础上应用静止无功功率补偿装置(SVC)对公共连接点(PCC)处进行不平衡控制补偿。仿真结果表明:应用SVC进行不平衡控制补偿,可以消除双馈异步风力发电机组PCC处电气量的不平衡度,提高了PCC处的电能质量。

| Abstract: | The grid connection model of doubly fed induction generator(DFIG) is established in DIGSILENT and the simulations under condition of three-phase voltages unbalance at point of common coupling(PCC) are conducted.It revealed that great negative-sequence component at PCC are existed while three-phase voltages are in unbalance and static var compensator(SVC) is required to control the unbalance for compensation at PCC.Simulation results indicated that SVC has ability of decreasing unbalanced factor of electrica... |
