Abdul Ghani A. A . Setting and Checking the Performance of Multiplev Distance Relays at Single Line to Ground Fault. International Journal of Computer Applications. 181, 35 ( Jan 2019), 37-41. DOI=10.5120/ijca2019918315
Distance relays perform a major role in the protection of transmission lines. Distance relays are operated with different zones in order to demonstrate that they can provide better protection. This paper explains the modelling of distance relay using Matlab/Simulink package. The paper discusses in detail the response of multiple distance relays at single line to ground (SLG) fault. The setting of distance relays on IEEE 3 Bus is presented for a quadrilateral characteristic of distance relay, considering sensitivity and selectivity criteria for protection zones.
