| 摘 要： | 光纤架空复合地线(OPGW)中故障电流的计算是其设计选型中的一项重要工作,针对OPGW工程计算中常遇见的两个问题所带来的计算误差:忽略经变压器中性点通过变压器线圈流向导线的电流及忽略导线系统与地线系统的互阻抗,提出一种基于EMTP软件的电磁暂态计算方法。该方法可以有效地解决上述问题,准确度较高。

| Abstract: | One of the major jobs in designing and model selecting of the compound optical ground wire (OPGW) is to calculate the fault current passing through OPGW as the short circuit occurs. To avoid errors resulted by the two following problems, one is neglecting the current flowing from neutral point of transformer to the conductor, and the other is neglecting the mutual impedance between ground wire system and conductor system, this paper proposes an electromagnetic transient calculation method based on EMTP, which can solves these problems efficiently and has a high accuracy. |
