Abstract

The invention relates to the electric engineering, namely to the compensation devices and may be used for augmentation of the electric power line varying capacity up to 1 kV and higher.The compensation device for electric power line includes a transformer and a capacitive reactance in the form of a capacitor bank, connected to the secondary voltage winding of the transformer. Novelty consists in that the device is connected in parallel to the electric power line or to the buses of the electric installation of the same or different voltage classes, the capacitive reactance is connected in series across the circuit of the secondary voltage winding of the three-phase transformer, and its value is chosen from the relationXc = XL + (R · tg φ2 - X2);whereXc - the capacitive reactance of the capacitor bank;XL - the inductive reactance of the network;X2 - the dissipation reactance of the secondary voltage winding of the three-phase transformer;R - the resistance of the secondary voltage winding of the three-phase transformer;φ2 - the phase shift between the current and the voltage in the secondary voltage winding of the three-phase transformer, equal to 89° 50'.The primary voltage winding of the three-phase transformer may be provided with a voltage regulator.<SDOAD>
