REACTIVE POWER SOURCE Russian patent published in 2008 - IPC H02J3/18 H01F29/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to high-voltage circuitry rated at 110 to 750 kV and be used for reactive power compensation and voltage stabilisation. The reactive power source (RPS) incorporates a three-phase magnetisation-controlled reactor connected in the high-voltage circuit, a three-phase capacitor bank with switches, the said reactor being made up of two sections and connected to the reactor in parallel to its phases, and an automatic control system. The RPS additionally comprises a switch for the reactor and capacitor bank to be connected to the high-voltage circuit, while the switches of the capacitor bank both sections are connected to the automatic control system. Note also that an optimum ratio is used, i.e. O_s=(0.8÷1.2)Q_r where Q_s is the power of every capacitor bank section, Q_r is the reactor power.

EFFECT: lower costs of equipment, optimum reactor power-to-capacitor bank section power ratio.
