摘要:
This paper presents new techniques for locating short circuit and open conductor faults on automated distribution systems. This is a unique method where short circuit and open conductor faults are treated simultaneously. The proposed fault location scheme is capable of accurately identifying the zone in which fault occurs. Temporary faults are also detected which may not result in a blown fuse. Data is made available to the substation remote terminal unit from various automated distribution system equipment. Decision is taken based upon the magnitude of fundamental frequency component of voltage and current phasor. Testing of the proposed fault location method has been demonstrated on the laboratory model for its practical use.
