METHOD OF REACTIVE POWER COMPENSATION IN AC SUPPLY NETWORK Russian patent published in 2014 - IPC H02J3/18 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering, first of all, to methods and devices for compensation or adjustment of a power ratio in converters or inverters, and in particular, relates to methods for compensation of reactive power in supply networks of industrial enterprises or individual loads of this power in order to meet the requirements of the power system to reactive power consumption. The proposed method consists in installation of a valve bridge 2 in each line of a supply network 1, and the bridge comprises in the inlet circuit at least one capacitor 3, and sending outlet current of the valve bridge 2 via the load providing for adjustment of current passing via this capacitor 3. The novelty is the fact that the load used is at least one light diode 6. Different modifications of this method are proposed, making it possible to optimise the compensation process.

EFFECT: when using the proposed method of reactive power compensation in the load network the inductive reactive power is compensated with capacitance reactive power of the source of light, therefore the power ratio (cosφ) is improved, simultaneously due to glowing of light diodes the compensator operates as a source of light of general lighting.
