140XBP01600 现场总线

低压通用变频输出电压为380~650V,输出功率为0.75~400kW,工作频率为0~400Hz,它的主电路都采用交-直-交电路。其控制方式经历了以下四代。

1.U/f=C的正弦脉宽调制(SPWM)控制方式

其特点是控制电路结构简单、成本较低,机械特性硬度也较好,能够满足一般传动的平滑调速要求,已在产业的各个领域得到广泛应用。但是,这种控制方式在低频时,由于输出电压较低,转矩受定子电阻压降的影响比较,使输出大转矩减小。另外,其机械特性终究没有直流电动机硬,动态转矩能力和静态调速性能都还不尽如人意,且系统性能不高、控制曲线会随负载的变化而变化,转矩响应慢、电机转矩利用率不高,低速时因定子电阻和逆变器死区效应的存在而性能下降,稳定性变差等。因此人们又研究出矢量控制变频调速。

2.电压空间矢量(SVPWM)控制方式

它是以三相波形整体生成效果为前提,以逼近电机气隙的理想圆形旋转磁场轨迹为目的,一次生成三相调制波形,以内切多边形逼近圆的方式进行控制的。经实践使用后又有所改进,即引入频率补偿,能速度控制的误差;通过反馈估算磁链幅值,低速时定子电阻的影响;将输出电压、电流闭环,以动态的精度和稳定度。但控制电路环节较多,且没有引入转矩的调节,所以系统性能没有得到根本改善。
