Power compensation
November 1st 2007 ABB has 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 laos, 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 sate-ofthe- art thyristor modules. Use of these static switches and advanced controllers is said to offer advantages over conventional contactor switched capacitor banks, such as ultra rapid power factor compensation, reduction of voltage drop and flicker, transientfree switching, high number of switching operations, and modular and compact standardised design, easy installation and advanced communications features with Modbus. The standard product has an advanced controller and offers a wide power range for all network voltages from 380 to 690V. More articles from ABB Ltd: |
