HYKON GROUP COMPANIES

UPQC stands for Unified Power Quality Conditioner. UPQC is an active series & shunt power line conditioner. It is a combination of STATCOM as well as DVR - a series compensating stage connected before the load in series with the mains using a matching transformer.

UPQC is the ideal power electronic device to solve the power quality problems. UPQC can mitigate voltage sag, swell, voltage transients and voltage unbalance. Hykon UPQC can supply VAR to the load.

• Load Voltage Regulation by series Voltage Injection.

• Dynamic Current injection for reactive power compensation

UPQC issued to compensate voltage and current harmonics, control input power factor to near unity as well as regulate the load voltage. It can be installed by the electric utilities to damp out harmonic propagation caused by resonance with line impedance and passive shunt compensators.

• IGBT based PWM Voltage Source Converter (VSC) technology.

• Maintain Grid Power Factor near to unity.

• Brings down Maximum Demand.

• Regulates load voltage against sag, swell and flickers.

• Eliminate Voltage Unbalance.

• Constant Output Voltage for a wide range of Input Voltages.

• State of the Art control strategy implemented with DSP based digital hardware.

• Function of a Servo Stabilizer with fast Correction time( < 1 millisecond).

• Excellent Dynamics with response time less than 1 millisecond.
