In this paper, a new method for the detection, location, and classification of faults in MTDC solar microgrid has been presented. Some issues such as the expansion of renewable energy sources and DC loads as well as the efforts to increase power quality and to reduce the environmental impact of electricity generation have led to the expansion of solar networks. Identifying the types and locations of faults is important to ensure that the service continues and further breakdowns are prevented and the protection’s selectivity characteristic is increased. In this method, an orbital kit is connected to the network. At time of fault occurrence in the network, the fault is detected by passing a current through the connected kits, measuring the traveling waves derived from the fault current, and applying it to a mathematical morphological filter. The location of the fault is determined using orbital equations and flow calculations. Mathematical morphology filter and signal energy analysis have been used to determine the type of faults. This method was tested with many faults. The results have indicated the accuracy of the proposed method. This method is resistant to changes in arcs resistance (up to 100 ohms) and has a very good performance in high impedance fault conditions (up to 1000 ohms).
