Modeling criteria for selection of remote protection settings with remote starting and dependent timer delay on lines with sources distributed generation

The parameters of special remote protections with remote start-up and resistance-dependent short-circuit loop time delay for branched partitioned lines with distributed generation sources are obtained, which take into account the peculiarities of parameters, operating modes and conditions of their operation. The necessary protection characteristics that can be used in the development of remote protection of such lines with a voltage of 6…20 kV are determined. The expediency using the circuit of connection of remote protection to linear voltages and phase current differences. The separate protection against double earth fault is used. In the absence of the latter - the scheme of connection to linear voltages and phase currents. The remote impedance protection is proposed to be evaluated by the value of the maximum arc. It is determined at a given coefficient of sensitivity of the voltage drop in the place of protection in the event of a short circuit.
