Hybrid power factor correction

Hybrid Power Factor Correction provide an instantaneous and effective response to power quality problems in low or high voltage electric power systems with lower cost. They enable longer equipment lifetime, higher process reliability, improved power system capacity and stability, and reduced energy losses, complying with most demanding power quality standards and grid codes.

Active power factor correction systems utilise power electronics and digital control to achieve active reactive current compensation for specific and high performance solutions. The  active power factor correction unit utilises closed loop control to correct power factor with a ¼ cycle (5mS) response.  This is suitable for unsteady fast changing loads such as cranes, welders, saws and debarking machines. However, sites containing loads such as these generally have a steadier base load. Considering active power factor correction produces a significant amount of heat, the question is whether the whole site needs active power factor correction when only part of the site needs it.A hybrid power factor correction system is comprised from both capacitor based and active power factor correction. Active power factor correction is used to cope with the unsteady fast changing portion of total load while capacitor banks support correction by correcting the steadier base load. This system offers the high level performance of an active system combined with the cost effectiveness offered by capacitor bank correction.
