摘要：

Traditional double-terminal travelling wave protection schemes are unable to satisfy the requirement of power systems stability and economy. In order to solve these problems for extra high voltage (EHV) transmission lines protection, a novel non-unit transient protection based on HHT energy spectrum is developed. The travelling-wave characteristics between internal faults and external faults are analysed. The main difference is that the travelling wave high frequency components energy caused by the internal faults is larger than that caused by the external faults due to the influences of line ...
