Fault-line selection and fault-type recognition in DC systems based on graph theory [PDF]

Protection and Control of Modern Power Systems, 2018
When a fault occurs in a DC system, the fault current rises rapidly with no zero-crossing point which makes fault-line selection and fault-type identification difficult. In this paper, an online detection and protection method based on graph theory, namely the “double D method”, is proposed for fault-line selection and fault-type identification in DC ...
