Determination of Fuse Characteristic for a Larger Coordinated Area between Fuse and Recloser Due to Distributed Generation

摘要

Nowadays distributed generation (DG) plays an important role in power networks such as reducing line losses, increasing the reliability of systems and so on. Because of the miscoordination between fuse and recloser due to presence of DG, it is more important to determine the fuse characteristic properly. This paper proposes a new method to determine fuse characteristic to have a wider coordinated area between fuse-recloser. The test system RBTS bus 2 is chosen as a distributed test system. The results show that the proposed method is efficient enough to make a larger coordinated area between fuse and recloser and the coordination in presence of DG for higher fault currents is maintained.
