An Adaptive Protection Scheme for Dual-Setting Directional Recloser and Fuse Coordination for Distribution Grids with Distributed Generation

The recloser-fuse coordination of the distribution networks equipped with distributed generators (DGs) may jeopardized by using the conventional overcurrent protection strategies thus degrading the network reliability. This research article focuses on the design of a protection coordination strategy based on the dual- setting directional recloser (DSDR) for an effective implementation of a fuse-saving scheme in distribution networks. The proposed DSDR-based protection strategy will assist the network operators by providing a significant flexible coordination range along with more accurate protection settings to meet the protection coordination requirements. The performance of the proposed protection scheme has been validated through its implementation on the IEEE standardized test system. Furthermore, this research work concentrates on the economical design of the protection strategy for distribution networks by utilizing fewer numbers of protective devices (PDs).
