| Summary: | Proper design of protection scheme is one of the problems that arise when
distributed generation penetration occurs. This is due to the change in in system
condition from previously radial to multi-source causing the magnitude and flow of
the fault current also change. Therefore, the conventional protection schemes that
do not consider the direction of flow become insufficient to protect the system. So
adaptive protection scheme that can 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 carried out on the IEEE 3-bus test
system on two conditions, the absence and penetration of distributed generation.
The algorithm calculation used MATLAB and then verified by Power Factory 2020
to clean the 3 phases, 2 phases, phase-ground and 2 phases – ground fault current.
This algorithm also uses contribution current to prevent the occurrence of
protection blinding and sympathetic tripping on this protection scheme. The benefit
of the proposed protection scheme is to maintain selectivity of relay operations
despite changes in system topology. |
