FIELD: electricity.
SUBSTANCE: automatic control method of energy flow distribution in ladder-type power transmission lines from an electrical substation to several consumers with variable loads is based on the usage of controlled shunt reactors of a transformer type at the beginning of each transmission line that regulate the voltage rate at the beginning of lines, characterized by the fact that the control signal is formed by comparing of some reference voltage with the voltage incident on each transmission line with a known resistance, because of that current is measured in a line as a function of changing consumer load, and the reference voltage value in each autoregulation channel of static or astatic type is set equal to a voltage drop in a power transmission line with average current rate under the load of each consumer. Announced method is expedient for using with several sufficiently extended power transmission lines from one electrical substation supplying consumers without intermediate branches of lines.
EFFECT: automatic maintenance of constant voltage for all consumers connected to an electrical substation by separate power lines, regardless of the variation in load values among consumers.
