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. |
