FIELD: electricity.
SUBSTANCE: in control process, measurement and synchronization of their switching process with respect to sine voltage at controllable shunt reactor is carried out, and the process for changing the state of controlled keys is performed at maximum and minimum applied to controllable shunt reactor of sine voltage. A control device includes a controllable shunt reactor containing two parallel connected branches each of which contains series connection of two reactors and controlled key. One of outputs of controlled keys in each branch is connected to opposite outputs of the controllable shunt reactor, and an additional controlled key is connected between common connection points of reactors in each of parallel branch.
EFFECT: provision of high quality electric power when controlling the controllable shunt reactor.
