Discrimination on Internal and External Faults using Differential Protection Schemes for Doubly Fed Induction Generator

摘要

This paper discusses a differential protection technique for Doubly-fed Induction Generators (DFIG). A new adjustment of differential protection using Support Vector Machine (SVM) is proposed. The system simulation takes into account many operating cases to obtain a relatively large number of data. The results show that the differential protection and the proposed adjustment are capable to distinguish correctly internal and external faults, for different operating conditions.
