New Study For Fault Location On A Distribution Network Using Traveling Wave

With the development of our society, the consumers of electricity quality and reliability have become increasingly demanding. The fault of power line impacts on social life, more and more, and it is difficult to estimate economic losses. Therefore quickly and accurately identify the faulty point is very important to the power system for the safe and reliable operation. The single-phase grounded fault location is the focus which researchers pay attention to the distribution network. And so far, there is not a kind of practical and effective fault location method to distribution line. This paper proposes a fault location method for distribution line --G-Traveling wave fault location by researching various methods of fault location. It can fast and accurately fault location when system occur single-phase grounded fault. Through analyze by software ATP simulation and verifies the practical of the method.
