对已发生过或可能出现的故障形式，进行了过渡过程动态故障模拟计算和特性分析，获得了动力系统全系统动态故障模式库。

The dynamic fault simulating computation and characteristic analysis of transition process is performed under fault conditions, so the dynamic fault pattern base for whole power system is acquired.

电力系统中，高压输电线路是最容易发生故障的部分，单相电弧故障是其中最主要的故障形式，并且往往是弧光高阻故障。

In power system, the kinds of faults often occur on HV transmission line, and the single-phase-to earth arcing faults are the main forms of the faults.
