IM Bortnik et al. Electricity, 1985, Ns2.), Containing a reactor group — three-phase power inductance, regulated by serially connected thyristor keys, and a capacitor bank connected in parallel with it, containing at least two sections of capacitors.
  • STK static thyristor compensator
  • the regulation of reactive power consumption from the network is carried out by turning on or off individual uncontrolled reactors that form a reactor group - a three-phase power inductance, and the regulation of the release of reactive energy into the network is carried out by connecting or disconnecting individual sections of the capacitor bank.
  • the number of switches - thyristor switches is equal to the number of groups of reactors and the number of groups of sections of the capacitor bank. Due to the need to change reactive power in small parts, the power and voltage of each switch-off reactor and capacitor bank are selected small. Moreover, their number corresponds to the full power of the group.
  • a known device cannot be connected directly to a network with a voltage of 1 10-750kV. In this case, it is necessary to connect a static thyristor compensator to an additional intermediate transformer at full power or to an additional tertiary winding of autotransformers installed at the substation, which is not always possible in existing networks.
  • the cost of equipment, installation and operation is high, since the static thyristor compensator occupies a large substation area, needs cooling, indoors and special maintenance, since it is controlled by high-voltage (up to 35 kV) thyristor switches for rated power, which does not allow short-term and emergency overloads inevitable in operation.
  • the disadvantages of the known static thyristor compensator is that it has limited functionality, insufficient reliability of the device and high cost in the manufacture and operation.

  • the controlled reactor in the known device can be connected directly to the network at a voltage of 1 10-750 kV and can regulate the consumption of reactive power, and direct connection to the network of a capacitor bank at high network voltages is impossible.
  • Capacitors in capacitor banks are not available for voltages greater than 35 kV, which leads to the need to manufacture batteries with their parallel connection.
  • the connection of capacitor banks in the known device directly to the network even when it is possible by the value of the mains voltage, causes overvoltage and inrush currents during switching. Therefore, to each capacitor bank at the substation, an additional arcing reactor corresponding to the connected capacitance is connected, which leads to a rise in the cost of the equipment installed at the substation.
  • the device occupies a large area of the substation, needs cooling, indoors and special maintenance.
  • Connecting capacitor banks to line ends the compensation winding of a three-phase controlled reactor is also not always possible. Firstly, in a number of designs of controlled reactors there are no compensation windings, and secondly, connecting capacitor batteries to control windings, if available in controlled reactors, is impossible due to the negative effect of switching capacitor sections on secondary circuits, in particular, on power unit and automatic control system.
  • the reactive power is controlled by the known device according to the minimum and maximum restrictions on the effective values of currents and voltages measured at the point of connection of the controlled reactor to the network, which does not allow for high accuracy and reliability of control in the presence of requirements for stabilization of reactive power and setting restrictions on its minimum and maximum values.
