description: In this paper, research of the problem of remote back-up in the networks of large power districts, where a powerful power source is present between the place of relay protection installation and the place of occurrence of a fault. During the research, the following tasks were solved: 1.Calculation of settings of the distance protection; 2.Evaluation of the distance protection sensitivity; 3.Offer an option for evaluating remote back-up of power transmission line, where sensitivity is not provided; 4.The creation of a model of distance protection terminal; 5.Check the correct operation of the virtual device created.The work was carried out on a fragment of the electrical connection diagram of the operating zone of the branch of JSC SO UES Leningrad RDU. Names of substations and power lines have been changed. The distance protection terminal model was developed in the LabView software environment. Because of research, it was proposed to consider that remote back-up is provided if the following conditions are met: 1.The damaged network element is de-energized after a series of a relay protection actions of adjacent elements; 2.The condition for thermal stability is met on the switching device of the damaged network element.
