Description by Manufacturer

Outline

Rapid growth of non-linear Loads, such as large capacity welding machine, crane, variable speed motor device, draws a large reactive power from the source supply, results in of voltage distortion and flicker in the system, which has an adverse effect on electric and control unit of the system IVC (Intelingent Var Compensator) compensates the reactive power drawn by the load from power system. IVC is DSP based Controlled power electronics system, compensates reactive power in real time stabilizes the voltage and reduces the flicker and power factor improvement.

Features

Patent No.0435620 as 3 phase 4-wire reactive power compensation system with linear response characteristics
Response speed: 5~16m/sec
Prevents the reduction of voltage of flicker
Transient free
Free from excessive switching phenomenon
Energy efficient and protects electronic device
Protects the switching devices and condenser, extends the life cycle of equipments
Easy to expand the capacity - Simple addition of module expands the capacity
Harmonic wave filter function (optional)
Load balancing (optional)

Application

Load
Irregular reactive power generating load and flicker generating loads, such as welding machine, variable speed drives, crane, and others.

System ratings
380V/440V, 30~1800kVAR, rated frequency 50/60Hz, rated circuit 3P3W/3P4W

Application areas
Metal Industry, chemical factory, shipping, and commercial factory

Principle of Operation of intelligent reactive power compensator(IVC)

Zero voltage control through thyristor, minimizing excessive phenomenon.
Applicable to short-time load based on rapid response control, such as welding machine and lifts
Harmonic wave filter function(optional)

IVC single line diagram and the reactive power compensation current wave

Effects

Power factor on the secondary side of transformer is kept at 98% on the average
Average current is reduced by 30%
Allowance capacity of transformer is kept at 30%
Reactive power is resolved in real time, minimizing the voltage flicker, no matter how high the simultaneous performance rate of load is
