Direct Current (DC) grids are emerging electric power systems with remarkable potential benefits. The High-Voltage DC (HVDC) grid improves reliability and efficiency of bulk power transmission systems and also facilitates grid integration of large-scale renewable generation systems. The medium-voltage and low-voltage DC grids and the DC microgrid facilitate integration of distributed energy resources. However, unresolved protection issues have constrained utilization of DC grids. The existing protection systems (relays) do not fully protect DC grids against adverse effects of faults (short-circuits) and disturbances.

直流电网是一种新兴的电力系统，具有显著的潜在效益。高压直流（HVDC）电网提高了大容量输电系统的可靠性和效率，也促进了大规模可再生发电系统的电网整合。中低压直流电网和直流微电网促进了分布式能源的整合。然而，未解决的保护问题限制了直流电网的利用。现有的保护系统（继电器）不能完全保护直流电网免受故障（短路）和干扰的不利影响。
