Abstract

The integration of distributed generation in medium-voltage distribution systems requires rapid evaluation of the protection coordination, especially the integration of synchronous generator-based generators where the contribution effect of short-circuit currents is relatively high. This research makes evaluation software for protection coordination based on fuse saving operation. Short circuit calculations on buses using the Zbus matrix. The increase in short-circuits current due to the installation of distributed generations based on variations in the size and location in the medium-voltage network results in need for redesigning the protection system. After a brief literature review, the methods and simulation results are presented. The low penetration level of 20% (0.406 MVA) has only a minor impact on protection coordination. Fuse replacement at limited locations can restore coordination of protection. The high penetration level of 60% (1.075 MVA) indicates that the protection coordination mechanism is still maintained if the installation is near a substation.
