A Qualitative Comparison of Distance-Based Protection Approaches for Active Distribution Networks

Objective: This paper presents a qualitative comparison of different recently proposed network protection schemes that are based on the distance function. From this comparison, possible opportunities identified to develop strategies oriented towards protecting active distribution systems. Methodology: research is carried out in two parts: first identify fundamental theoretical aspects protection, its main problems, and description most important relevant recent years. The second part consists selecting elaborating analyzed. makes it establish advantages disadvantages each proposals used conventional electrical networks or networks. Results: As result research, consider design identified, which therefore strongly affect performance. These summarized comparative table, supports future related Conclusions: can be stated solutions analyzed, despite being within scope applied networks, have problems solve. None these protects for all types failures selective, sensitive, reliable, cost-effective way while guaranteeing minimum supply interruption consumers.
