The frequency of broken-line fault occurred in distribution network is increasing over the past years. Broken-line fault will create negative sequence and zero sequence voltages, which will seriously affect the normal work of loads. However, distribution network has not equipped with special protection against broken-line fault yet. In this paper, single-phase broken-line fault in distribution network...
Line break fault is becoming more and more frequent in 10kV neutral point non-grounded distribution system. This paper takes 10kV distribution line single-phase line break fault as the research object, analyzes the characteristics of electrical quantities when single-phase line break fault occurs, including single-phase line break without grounding point, single-phase line break with grounding at...
In this paper, the traveling wave based differential protection for HVDC transmission line is proposed, in which the backward traveling waves in mode 1 are employed to establish the traveling wave based protection, at the same time the zero-mode current detector is utilized to determine that which is the faulty line for bipolar HVDC lines. The operating traveling wave is the differential of the backward...
