摘要
根据电压型PWM整流器的主电路结构,建立了整流器在同步旋转DQ0坐标下的数学模型。根据整流器的无源性,构建了带输出电压调节因子的无源控制器。仿真实验将无源控制器与传统电流内环电压外环的双闭环PI控制器进行了对比。结果表明带电压调节因子的无源控制器具备更好的动静态性能,特别是在参考电压和负载较大扰动的情况下,具备更优动态响应性能的同时保持输出电压几乎不变,因此带电压调节因子的无源控制方法是可行和有效的。
The mathematical model of the rectifier under DQ0 synchronous rotation frame is deduced from the main circuit structure of the voltage-source PWM rectifier. A passive controller with regulators for output voltage is constructed on the basis of the passiveness principle of the rectifier. In the simulation experiments, the passive controller is compared with the traditional double closed loop PI controller with current inner loop and voltage outer loop. Results show that the passive controller with voltage regulator has better dynamic and static performance, especially in the case of a larger reference voltage and load disturbance, it is of the better dynamic response performance and can maintain nearly no change of the output voltage. It proves that the passive control method with voltage regulator is feasible and effective.
