A Pattern Recognition Approach for Detecting Power Islands Using Transient Signals—Part I: Design and Implementation

摘要: A novel, pattern-recognition-based approach for fast detection of power islands in a distribution network is investigated. The proposed method utilizes transient signals generated during an islanding event to detect the formation island. decision-tree classifier trained categorize generating events as “islanding” or “non-islanding.” feature vectors required classification were extracted from current and voltage through discrete wavelet transform. technique tested on medium-voltage system with multiple distributed generators. results indicate that this can accurately very fast.
