| Research Abstract |
For analysis and diagnosis of long-term nonstationary partial-discharge data, recurrence plots are considered to be useful. In this study, regarding state changes in partial-discharge sites as changes of driving forces and parameters, we proposed algorithms for reconstruction of driving forces and detection of change points using recurrence plots. Further, we revealed similarities in mathematical structures of partial-discharge phenomena and other phenomena and systems in various research fields.
