ABB launches new Dynacomp dynamic response compensator 
(31/12/2007)
ABB has a launched a new generation version of its Dynacomp dynamic response compensator developed to provide fast and smooth reactive power compensation to solve a variety of industrial network power quality problems associated with fast variable loads such as: low power factor, voltage sags, flicker and high harmonic levels.
The Dynacomp acts as an ultra-rapid and transient free capacitor bank with the reactive power step switching carried out by state-of-the-art thyristor modules. The use of these static switches and advanced controllers offers a number of key advantages over conventional contactor switched capacitor banks including: ultra-rapid power factor compensation; reduction of voltage drop and flicker; transient free switching; very high number of switching operations; modular and compact standardized design; easy to install and extend; advanced communications features with Modbus.
The new Dynacomp is equipped with an advanced controller and offers a wide power range for all network voltages ranging from 380V to 690V. It is available in both three-phase and single-phase versions and there is also a choice of detuning reactors to suit all types of application.
Starting from a few hundred kvar, the Dynacomp is available for applications up to several Mvar to cater for even the largest loads. Its modular design and CAN bus control makes it easy to use standard power units to build a system with the necessary power rating to suit the exact load requirements. It is also simple to extend the Dynacomp to adapt to changing future needs.
In addition to reactive power compensation, the Dynacomp also partially filters harmonic currents, thereby reducing total harmonic distortion and improving the network power quality.
