Chain typed RNSVG (Static Var Generator) is the latest generation of dynamic reactive power compensation device based the IGBT, also known as the STATCOM (Static Compensator) in the world. As the advanced equipment with cutting-edge dynamic compensation technology, it is the third generation of dynamic reactive power compensator after the static reactive power compensator controlled by mechanical switching capacitor and thyristor.

Working principal

A self-commutated bridge circuit with a high power core of IGBT shall be connected in parallel to the power grid by commutation reactor (or transformer), then adjust the amplitude and phase position of output voltage from above bridge circuit in the AC side, or directly control the current in the AC side to absorb or give out the reactive power current in needs to realize the dynamic reactive power compensation.
