| 摘要: |
| 针对低转速下运行的定子双绕组感应电机（DWIG）风力发电系统，提出了一种简单易实现的控制绕组间接磁场定向控制策略。该定向方法忽略控制绕组的阻抗压降，以与控制绕组电压矢量正交的方向作为矢量控制的定向基准，使系统的电压调节控制得到了简化。省去了直接磁场定向控制的复杂积分运算，仅需控制绕组电压采样及简单的2／3坐标变换。采用滞环电流控制策略调节系统的输出电压，在一台750 r／min、20 kW DWIG样机上进行了仿真和实验研究，证明了理论分析和该定向方法的正确性和有效性。 |

| Abstract: |
| A simple indirect field oriented control is presented for the DWIG（Dual stator-Winding Induction Generator） wind power system operating under low rotor speed，which ignores the voltage drop on the control-winding impedance，takes the orthogonal direction of control-winding voltage vector as the orientation reference of vector control and facilitates the voltage regulation. It only executes the control-winding voltage sampling and the simple 2／3 coordinates transformation，avoiding the complex integral operation of direct field orientation. The system output voltage is adjusted by the hysteresis current control. The simulative and experimental results for a 20 kW 750 r／min DWIG prototype demonstrate the correctness and effectiveness of theoretical analysis and the proposed orientation strategy. |
