Centralised compensation Centralised compensation by means of an automatic capacitor bank with automatic regulation offers the most simple and economical solution. The reactive power is subdivided in a number of capacitor steps that can be connected independently. A reactive power controller continuously measures the needs of the installation and connects or disconnects the capacitors until the ta...

ZDDQ static var generator connects a self-commutated bridge circuit through a reactor or directly connected in parallel to the grid to adjust the phase and amplitude of the output voltage on the AC side of the bridge circuit, or directly control its AC side current so that the circuit absorbs or Send out the reactive power that meets the requirements to achieve the purpose of dynamic reactive powe...
