METHOD OF CONTROLLING OF CAPACITANCE OF CONTROLLED CAPACITOR GROUP AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC H02J3/18 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and power electronics and can be used to control sources of reactive power in power systems. Controlling the controlled capacitor groups is carried out by controlling the state of the thyristors of the bidirectional thyristor keys by measuring and synchronizing the switching process thereof with respect to the sinusoidal voltage on the controlled capacitor groups, and control pulses of thyristors of bidirectional thyristor keys are changed at the moment of achieving sinusoidal voltage on controlled capacitor group of zero value. Control device of capacitance of controlled capacitor group includes controlled capacitor group consisting of parallel connected branches containing serial connection of capacitor and bidirectional thyristor switch, with parallel connected to them additional bidirectional thyristor key, and in series with controlled capacitor group includes current-limiting reactor.

EFFECT: reduced weight and size, cost and increased efficiency of control devices of capacitance of controlled capacitor groups.
