17、SU的基本原理的基本原理ISU 的主要功能是控制电网和直流母线之间的能量转换。交流电抗 器的使用目的(电抗的表达式 X = jwL)是平波以及给开关式供电单元 工作做能量储存。在电网和ISU 之间的能量转换方程如下所示：仅当在两个电压矢量之间存在角度差时，传递有功功率。无功功率的传递方程如下所示意： ACS800MD ISU - 26ISUISU的基本原理的基本原理为了得到所需的幅值和有功无功的流向，必须控制变频器的电压矢量幅值及其相位d (相对线电压矢量) 。通过保持电缆和传动设备之间的功率( 能量)平衡，对直流母线电压进行控制。 相角符号决定了功率流向,这样，ISU既能够从电网获取能量，也

18、能发出能量返回电网 。 为了在对应的输出电压等级实现COS = 1.0通过设置磁通的大小，来控制交流输入电压。 对ISU进行控制必须测量直流母线电压和两个线电流。定子磁通（ISU 电压矢量的积分）的计算是通过对电压矢量（用来产生ISU的输出电 压）积分得到的，这是因为电网上存在的电压可以认为是由绕组的旋转磁场所产生的。 每个绕组是线电压的一相。绕组上的电压能用下面的 公式来表达： ACS800MD ISU - 27ISUISU的基本原理的基本原理ISU 所产生的实际转矩是通过磁通和电流的矢量积计算得到的： 功率是由转矩和角速度的乘积得到的，这样，ISU既能够从电网获取能量，也能发出能量返回电网

19、： P = wT 如果电网的频率是一个常量，那么功率就直接和转矩成正比。通过控制 转矩，在ISU和电网之间所传送的功率就可以设置成某个值，从而保证直流环节电压的稳定。这些基本条件就使得通过磁通和转矩实现直接转矩控制。 ACS800MD ISU - 28DTC Applied to Line ConverterDTC Applied to Line ConverterDIRECT TORQUE CONTROL = DIRECT POWER CONTROLDIRECT TORQUE CONTROL = DIRECT POWER CONTROL直接转矩控制直接功率控制直接转矩控制直接功率控制THE
