摘要
研究了输电线路的故障地点和故障过渡电阻的随机性对电力系统动态安全性测度的影响。算例表明 ,输电线路的故障地点和故障过渡电阻的概率分布对电力系统的动态安全性的影响是比较明显的 ,因此在安全性测度的研究中有必要考虑其影响。
This paper analyzes the influence of the probability of line fault position and the transition resistance to the power system security measure.From the illustrative example,we can see the obvious influences of the probability distribution of line fault position and the transition resistance to the power system security.Therefore,it is necessary to consider the affects of these two factors in the power system dynamic security measure.
