The zero sequencecomponent and the positivesequencecomponent equations of transmission lines are derived on the basis of telegraph equations.
运用电报方程推导出三线-地耦合传输线零序分量和正序分量传输线方程。

The proposed method doesn't need hardware synchronization circuit and can perform the calculation of fundamental positivesequencecomponent of the supply voltage in real time.
这种方法不需要硬件同步电路，能实时地计算电源电压中的基波正序分量。
