摘要
提出了基于控制绕组磁链的无刷双馈感应发电机空载并网电压相位控制方法,根据无刷双馈感应发电机的数学模型及控制策略构建了控制系统结构框图。设计了空载并网实验的硬件电路,实现了无刷双馈感应发电机电压相位的实时控制。在此基础上完成了无刷双馈感应发电机在空载并网时对电压幅值、频率、相位的自动调节,能够在满足并网条件时自动并网,提高了系统并网时的快速性和稳定性。不同转速下的空载并网实验结果验证了所提方法的有效性。
A no-load grid-connected voltage phase control method of the brushless doubly-fed induction generator(BDFIG)based on the control winding flux was proposed,the control system structure block diagram was constructed according to the mathematical model and control strategy of BDFIG.The hardware circuit of the no-load grid connection experiment was designed,the voltage phase of BDFIG was controlled in real time.On this basis,the voltage amplitude,frequency,and phase of BDFIG was automatically adjusted,and BDFIG could automatically connect to the grid when the grid connection conditions were met,which improves the rapidity and stability of the system during grid connection.The effectiveness of the proposed method was verified by the no-load grid-connected experimental results of BDFIG at different speeds.
