Summary:A significant role in the problem of two-end determination of a fault location with unsynchronized measurements at the ends of the line is played by the hypothesis of the dissipation of fault, according to which in order to determine the fault location on the line, objective functions are applied, representing reactive parameters that take a minimum at the actual location of the fault. The required improvement of the method for the fault location determination is achieved due to the effectiveness of the general model of the faulted power line, which forms estimates of electrical quantities at the left and right of the intended fault location. In this case, the synchronization of currents is carried out subject to the phase difference of the calculation voltages of the power line models on both sides of the intended fault site.
