Proper design of protection scheme is one of the problems that arise when distributed generation penetration increases. This is due to the changes in system condition from previously radial to multi-source causing modifications of the magnitude and flow of the fault current. Therefore, the conventional protection schemes that do not consider the direction of the current flow become insufficient to protect the system. Therefore, adaptive protection scheme that can adjust its settings dynamically depending on the condition of the system is needed to keep the system safe. The proposed adaptive protection scheme is tested on the IEEE 3-bus test system on two conditions, the absence and presence of distributed generation. The algorithm is implemented on MATLAB and then verified on Power Factory 2020 to test its effectivity to clear the 3 phases, 2 phases, phase-ground and 2 phases – ground fault current. This algorithm also uses current contribution to prevent the occurrence of protection blinding and sympathetic tripping on this protection scheme. The proposed protection scheme is able to maintain the selectivity of relay operations despite changes in system topology, especially due to distributed generation. |
