Abstract:
A polyphase static var compensator arrangement for supply voltage regulation in a voltage supply system, comprising:a) a plurality of capacitors, each capacitor being provided for each of a plurality of phases;b) a number of switches being respectively connected in series with a corresponding number of capacitors in a corresponding number of phases, said number of switches being no less than one smaller in number than said plurality of phases;c) a transformer electrically coupled to the capacitors for transferring energy away from the capacitors;d) an energy-dissipator operatively associated with the transformer, for dissipating the energy; ande) the switches being operative for sequentially switching their respectively connected capacitors out of the system, and for discharging the energy from the capacitors through the transformer to the energy-dissipator.
