One of the most important characteristics of the smart grid is the keen monitoring. At the same time, electrical energy has to cover the entire demand and electricity should be generated all the times. However, the electric power companies connected via transmission lines over wide area should consider the cost performance as well as the high reliability. In Japan, power system has a longitudinal structure which results in a wide-area oscillation with duration of 2 to 3 seconds and relatively weak damping characteristics. Phasor Measurement Units (PMUs) have been placed at different Japanese universities, to analyze the power system characteristic. These PMUs are employed to analyze variation of power system stability in Western Japan power system. This paper shows the dynamic characteristic of Japan power system using phasor difference data by PMU. In this research, a simplified oscillation model has been used to estimate eigenvalue of the wide-area oscillation mode. Moreover, the two-point differentiation which has been used during the differentiation process at a previous method has been modified by a three-point differentiation in an improved method. The relationship between stability and eigenvalue analysis are shown as low demand season and high demand season respectively
