The given work is devoted to study of comparing of operation DLP on the line with distributed and lumped parameters. Tasks that were solved during the study: 1. Study of the feature of DLP and the requirements that apply to these devices. 2. Drawing up a functional test program for research. 3. Creation of a network model in which tests will make place. 4. Comparison of the results obtained and addition of the conclusion. The analysis was carried out by the method of mathematical modeling using the Matlab Simulink software, in which a network model was created. After that, the LabView software was used to simulate the protection algorithm. As a result, the operation of the differential line protection in different situations was analyzed. A standard-based functional test program was also developed, which is necessary to verify the functioning of the remote sensing system. Based on the conducted studies, it was clearly determined that the use of the line model with distributed parameters in general does not affect the operation of the differential protection in comparison with the line model with concentrated parameters. But at the same time, in the transients, differences were revealed for the two models and characteristic features inherent only for lines with distributed parameters.
