摘　　要：当电力系统发生故障时,如何快速、准确地查找故障发生地点,并确定故障类型变得至关重要.本文运用经典的对称分量理论,得出快速诊断线路故障的一种方法,以一个实际的简单电力系统为例,通过运用VisualBasic语言进行编程实现,验证了"电力系统故障快速诊断系统"的正确性.When the fault of a power system happens,it is important to diagnose the fault and decide the style of the fault timely and accurately.In this paper,by using the classical symmetrical component method,we find a way to diagnose the line-fault rapidly.Taking a simple power system as an example,and programming with the Language Visual Basic, we validate the correction of the rapid diagnosis program to a power system faults.
