Validation of mathematical model of differential protection
Romanyuk, F. A.; Novash, I. V.; Loman, M.; Wegierek, P.; Szrot, M. (2014)Comparison of results of mathematical modeling and field tests of a transformer differential protection is presented in this paper. An inrush current mode, external two-phase and three-phase faults are considered. Proposed mathematical model can be used to test differential protection in different modes of transformer operation.2022-08-09 -
Wye-connected current transformers simplified model validation in Matlab-simulink
Romanyuk, F. A.; Novash, I. V.; Rumiantsev, Y.; Wegierek, P. (Wydawnictwo SIGMA, 2015)This paper presents the wye-connected current transformers (CTs) simplified mathematical model with the initial data based on nominal parameters (nameplate data) of the simulated CT. Designed user-friendly graphical interface allows to specify the CT data (nominal parameters, remanence and burdens) in convenient form. Results of the carried out experiments confirmed the CT model ...2022-07-25
