“…The disadvantages of such devices are associated with the maximum permissible operating currents of semiconductor elements, which is a barrier to the use of these devices. A hybrid system using a currentlimiting reactor was proposed in [24], but this system does not provide advanced disconnection of the circuit when fault currents occur.…”

Based on the controlled parameter speed and acceleration change measurement along with use of a current-limiting reactor, short circuit currents protection efficiency increase system has been proposed. To achieve this goal, a number of auxiliary tasks have been solved: the parameters of the system elements under study in relative units have been determined; math model of the system under study has been developed with subsequent modeling; advanced control formation system based on the application of the speed and acceleration measurement of the controlled parameter has been proposed. Analysis of the research results showed that the application of the proposed system will improve the protection efficiency against short circuit currents by limiting the value of peak current along with elimination of disadvantages associated with the current-limiting reactors use, such as voltage drops and power losses in transient conditions which confirms the perspective of proposed system.
