Urgency of the problem. Higher probability of the transverse asymmetry (short-circuit (SC)) in the 6–110 kV distribution grids as compared to the longitudinal-transverse and longitudinal asymmetry on overhead lines (phase wire breaks, breaks with SC) has led to less attention to it [1-8]. It should be noted, breaks of phase wires of overhead transmission lines (overhead lines), even at a short circuit...
Selection of the DG interconnection protective relay is based on several criteria such as power system characteristics, the dynamic response of the generator, the system grounding, the DG transformer connection, etc., as well as the protection policy of the utility and coordination requirements. The interconnection protection IED design can be summarized as follows: disconnection of DG plants when...
