ISU的基本原理 ISU的基本原理通过一个交流电抗器的等效电路和矢量图的来表述。 这里： y1 电网磁通矢量 y2 变频器磁通矢量 ____ 电动 _ _ _ 发电 U1 电网电压矢量 U2 变频器电压矢量 UL 交流电抗器电压矢量 y1 电网磁通矢量 y2 变频器磁通矢量 yL 交流电抗器磁通矢量 d 功率转换角

ISU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：

ISU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：

ISU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： 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。

DTC Applied to Line Converter DIRECT TORQUE CONTROL = DIRECT POWER CONTROL 直接转矩控制＝直接功率控制 THE VOLTAGE AT NETWORK IS GENERATED BY THE FLUX 通过磁通控制电网侧电压 THE POWER CAN BE INTERPRETED DIRECTLY TO TORQUE 功率与转矩具有直接对应的关系

DTC Control loop DTC控制环 - Same hardware components used as in the motor feeding inverter. - Two 100 microsecons three phase short circuits is done to synchronise the line converter to the net frequency.

 Hysteresis Control 滞环控制 Controls amplitude of flux (=voltage) and torque (=power) 控制磁通（＝电压）与转矩幅值（＝功率）  s r 3 4 U 5 6 2 1 x y  o t a i n d e c - Stator flux corresponds to Line converter output voltage and Rotor flux corresponds to net voltage. Motor torque corresponds to the transmitted power. The output voltage stays normally constant, and the power is controlled by changing the power transfer angle ’r’ between the line converter output voltage and net voltage. It is possible to achieve the required torque very effectively by rotating the flux vector directly in a certain direction as fast as possible. The idea of Direct Torque Control is straightforward: If more torque is needed, the purpose of the next power stage switching is to fulfill this demand. The instantaneous value of the flux vector is controlled in order to achieve the required torque. The optimal switching logic defines the best voltage vector according to the actual value of the torque with torque reference. The absolute length of the flux is also taken into account in the switch selection. For example, in Figure 4, the voltage vector U4 decreases effectively the radial component of the flux vector while simultaneously moving the flux vector tangential component in the direction of rotation. The tangential movement makes the angle and torque to increase. The radial change affects the length of the flux thus changing the output voltage. The aim is to force the flux vector to turn into the direction where both reference values of the torque (power) and flux (voltage)are achieved.

Power Factor control 功率因数控制 Reactive power control reference is normally zero. IGBT Supply Unit can be used to compensate the reactive power produced by some other devices which are connected to the same line supply.

Harmonical components 谐波成分 Spectrum components of the line converter 整流器频谱图 Total harmonical distortion is very small (<5%). Low frequency harmonical components (5. and 7.) are also small compared to 6 - pulse rectification.
