摘要/描述

This paper proposes a digital computer technique based on wavelet transform for generator incomplete differential protection scheme. Exploitation of the fault-generated high frequency currents, the new scheme can provide fault detection with high sensitivity and is also capable of discriminating between internal and external faults. The effectiveness of the proposed scheme was verified both in the experiment and in the field. The results show that the scheme can detect the generator fault with high sensitivity and selectivity during all operation conditions.
