| 摘 要： | 为克服电网电压跌落或者定子参数的变化所引起的给定(计算得到)定子磁链相位角度与实际角度的偏差,提高控制系统的抗干扰能力,利用双馈电机的数学模型推导出其偏差并进行补偿.在此基础上,提出了基于定子磁链相位偏差补偿原理的定子磁场定向矢量控制,有效地保证了定子磁链d轴分量应为零的矢量控制成立条件,从而使控制系统具有一定的低电压...

| Abstract: | In order to overcome the deviation of the actual stator angle and the given(calculated) stator angle arising from the grid voltage dropping or the parameter changes of the stator side,so that the anti-jamming capability of the control system will be improved,the stator flux angle deviations was derived from the DFIG mathematical model.Based on the stator flux phase deviation compensation principle,a new stator flux-oriented vector control was proposed.While the d-axis component(set to zero) of stator flux i... |
