Some network elements are more readily represented by sequence networks than by ordinary phase networks.This is the case,for example,for synchronous machines,synchronous motors and generators produce a positive sequence internal voltage and have terminal impedance.For reasons which are beyond the scope of these notes,the impedance to positive sequence currents is not the
same as the impedance to negative or to zero sequence currents.A phase-by-phase representation will not,in many situations,be adequate,but a sequence network representation will.Such a representation is three Thevenin equivalent circuits,as shown in Figure 6

一些顺序网络比普通网络单元更容易替换网络单元.在这种情况下,举例来说,比如同步电机,同步电动机和生成器产生了正序内电压和终端电阻抗.由于这些都超出了上述范围,全电阻对正序电流的阻抗与阻抗电流与零序电流不同.顺序电流大部分情况下不是足够代换的,但是顺序网络却可以做到这点.这种代换被称为第三戴文宁等效电路,如图6所示.
