Title    Effect of Line Fault Location on Power System Stability  Analysis
Abstract
A necessary condition for the normal operation of the power system is that all generators keep pace running.Power system transient stability analysis is the analysis in the system's stability by the large disturbance.That is the capacity of the system to keep the generator running synchronously by the large disturbance.Large disturbance here refers to various short-circuit fault,open fault,the investment and the removal of large-capacity generators, load, or an important power transmission equipment, etc.Currently, transient stability study methods are time domain method, the direct method and mixing method.This paper analyzes the single-machine infinite bus system and multi-machine system transient stability determination method.Writing multi-machine system stability judgment procedure by MATLAB.Determining the transient stability of the system used in this paper.And on this basis,by changing the fault location of the line,analysing the influence of different fault location to the transient stability of the system,get some conclusions.
