A Study on Algorithms of Fault Location for (a) Symmetricungrounded 3-Phase System Based on Modal Analysis Theory
-
Abstract: Based on distributed parameter circuit theory and modal analysis theory, a number of new algorithms of line-to-line, single-line-to-ground & double-line-to-ground fault location for (a)symmetric ungrounded 3-phase system are proposed in accordance with the characteristic of the system. Simulation of fault location by computer and tests on the fault model simulation lines show that the algorithms presented in the paper are effective.
