FIELD: electrical engineering.
SUBSTANCE: method of regulating transmitted power in distribution networks, the value of the current setting for disconnecting the overhead distribution line (OHL) is formed based on the value of the existing current load of the overhead line, as well as data on the maximum permissible current value in the conductive part of the line; continuous measurement of the existing current load is carried out on the power transformer and the distribution cable line (CL), while at the first level of voltage class 10 kV and above, the current value in the overhead line is measured and, based on the obtained current value, the preliminary current load of the power transformer is determined. Based on the preliminary current load of the power transformer and data on the maximum permissible value of the current at its terminals, a setting is formed to turn off the queue of non-priority loads to unload the power transformer, then on the low side of the power transformer the current value at its terminals is measured and, based on the current value obtained during the measurement, the preliminary current load of the cable line is determined. Based on the values of the current at the terminals of the power transformer, preliminary current loading of the cable line and data on the maximum permissible value of the current in the cable line form the current setting value for disconnecting the queue of non-priority loads to unload the cable line, while continuously measuring the values of the currents in the overhead line, at the terminals of the power transformer and in the cable line and compare them with the corresponding generated settings, and if the value of the current in the overhead line, at the terminals of the power transformer or in the cable line is equal to or exceeds the value of their current setting, they turn off the queue of the non-priority load of the corresponding network element, and if the value of the current in the overhead line decreases, at the terminals of the power transformer or in the cable line below the value of their current setting, reverse connection of the non-priority load of the corresponding network element is carried out.
EFFECT: improved reliability of power supply to end consumers.
