ARRANGEMENT METHOD OF CAPACITOR DEVICES IN 0,4 KV RURAL DISTRIBUTION NETWORKS Russian patent published in 2015 - IPC H02J3/18 

FIELD: electricity.

SUBSTANCE: method involves determination of values of lengths of the main line, two-phase and three-phase branches of the main line; measurement in assemblies corresponding to the obtained values of voltage and a power coefficient; with that, main line length value L_M is determined according to a certain formula. After that, in the assembly corresponding to the obtained value L_M there measured are total voltage losses relative to a transformer substation (TS) and a reactive power, if they do not meet maximum allowable values, a capacitor plant (CP) is installed in the assembly; and if actual total voltage losses and reactive power coefficient in this assembly meet maximum allowable values, and voltage losses and reactive power coefficient of domestic consumers do not meet maximum allowable values, length value is determined for two-phase and three-phase branches of main line L_2-3. Then, total voltage losses relative to TS and reactive power coefficient are measured in the assembly corresponding to the obtained value, if the measured values do not meet maximum allowable values, CP is installed in this assembly; then, values of level of voltage and reactive power coefficient of domestic consumers are measured in a line; if measured values do not meet maximum allowable values, CP is installed in the branch line of the main line, which is the most distance from TS.

EFFECT: providing voltage of consumers at an allowable level, compensation of reactive power directly at its consumer and simplification of calculations of arrangement points of capacitor devices.
