要約(日本語): By using this analysis and understanding the margin that is difference between voltage in fault and voltage stability limitation, it is possible to assess the stability of the whole system. So, we can evaluate Pmax(%)(Ref1) which stands for the ratio of transmission capacity and stability limitation voltage on each node when failure occur at a transmission line of a system, called as (N-1) system, and deal effectively with problems, depending on the Pmax. So, if we can implement the analysis in real time in case of failure, stability of system will be secured. Then, an easy calculation method of the analysis is indispensable. However, in traditional method, multiple calculations of nonlinear simultaneous equations are necessary and it is not necessarily efficient.Then, in this research, we suggest an efficient calculation method in (N-1) system by using compensation sensitivity value.
