Abstract
AbstractFaults in power transmission systems often take place through long arcs in air. Therefore, the dynamic interaction between a fault arc and the power network is extremely important in relation to the single‐ or three‐pole autoreclosure and to the system protection relaying. Using the theory of constrained switching arc a new dynamic black box model of a long fault arc is developed. Power system transients caused by arcing faults are successfully simulated using the version ATP (Alternative Transients Program) of the universal Electromagnetic Transients Program (EMTP).
