DEVICE FOR PEAK LOAD COVERAGE Russian patent published in 2008 - IPC H02J3/32 

FIELD: electrical engineering.

SUBSTANCE: device for power consumer peak load coverage (VB), which is connected to the AC terminal of electric network (ENT) of common use, with inverter (WR), which is supplied from DC accumulator (BAT) and is connected with its output parallel to electric power supply (EB) of consumer (VB), with measuring device (Z1, Z2), which is connected into circuit (EN) of consumer connection, and control device (STE). With the help of measuring device (Z1, Z2) control device controls power consumption of consumer (VB), estimates from it the volume of electric power (E^*(T)) consumption till the end (T) of preset time interval, for instance, by means of linear extrapolation, and if predicted value obtained in this manner exceeds preset threshold value (E_max), it connects inverter (WR) for consumer supply maintenance. Receiving device is provided, for instance, in the form of centralized telecontrol receiver, which is connected to control device (STE) and through which operator of network (ENT) of common use may initiate the electric energy make-up independently on energy consumption by consumer.

EFFECT: possibility to arrange smooth make-up with additional electric energy.
