Control device transmit power in distribution networks at deficiency of capacities in the power system

摘要

The invention relates to electrical engineering and can be used to minimize outages of lines extending from the supporting substations automatic frequency discharge device (ACR) [1] that is the deficit of active power in the power off part acts on less critical. The technical result consists in the possibility of adjusting the setpoint load relay priority depending on the free capacity in the power system based on relay loads priority and is achieved by the known transmit power control device in distribution networks with a deficit power distribution grid point includes relay loads priority, a current sensor comprising - current transformer, whose output is connected to a comparator, contactor signaling device priority and indirect oritetnuyu load, according to the utility model is provided with a regulator setpoint current, an additional communication channel, free capacity control block installed in the distribution grid point, the output of which through an additional communication channel connected to the input of the current setpoint value regulator whose output is connected to a comparator. 1 Fig.
