Impact on Protective Device Sequence of Operation in Case Distributed Generation Integrated to Distribution System

This study aims to evaluate the impact of distributed generator (DG) connection grid. The simulated results present parameters system required install DG on end main distribution feeder. Various parameters, such as voltage, current, and protective relay coordination are modelled after actual provincial electricity authority (PEA) system. case studies compared without with connections grid by finding difference devices. indicate that malfunction can be fixed in order priority devices, which operate according parameter setting. Additionally, coordinate functions between recloser fuse devices both phase ground configurations operating zone prevented drop-out melting or burning out. Based result, this problem is providing a directional device increasing fuse-link rated 40k installation for replacing conventional sizing, improve performance fault occurrence investigate reliability stability
