This paper will show the analytical analysis of multiple parallel line corridors with their mutual coupling and inter infeeding effects. Based on a generic model in symmetrical components the analytical description of the measured impedances of distance protection relays on faulty and unfaulty parallel lines will be presented. Based on that, worst case considerations will be carried out. They will...
This paper is dealing with an urgent task of protection coordination in nationwide power systems. The coordination of overcurrent protection is strongly depending on the network configuration in contrast to distance or differential protection. Proposed concepts should be evaluated applied to the network. Nowadays numerical simulation tools like PSStradeSINCAL provide the possibility of a holistic...
