DEVICE OF CENTRALISED COMPENSATION OF REACTIVE POWER IN n-PHASE HIGH-VOLTAGE NETWORK Russian patent published in 2015 - IPC H02J3/00 H02J3/18 

FIELD: electricity.

SUBSTANCE: device contains a reactive power regulator, a reactive power measuring instrument, a voltage transformer, n batteries of cosine capacitors, each comprises m cosine capacitors the first leads of which are integrated and connected to the common bus, n contactor units, each comprises m contactors, n batteries of tuning cosine capacitors are also added, each comprises k tuning cosine capacitors the first leads of which are integrated and connected to the common bus, n blocks of switches, each comprises k switches, a controller, n analysers of harmonious composition of a signal, and the total capacity CΣbt in each of n batteries of tuning capacitors is selected from the relation CΣbt=Cc, where Cc - the capacity of the single capacitor in each of n batteries of cosine capacitors, where n, m, k>/=1.

EFFECT: improvement of energy saving in networks with variable load.
