Introduction: As many electrical equipment are based on the principle of electromagnetic induction such as transformers, motors. Reactive power is generated to establish an alternating magnetic field and induced flux. Static Var Generator is currently the best solution in reactive power control filed.
Working of SVG : Static Var Generator is a power electronics-based device connected in parallel with the load that requires harmonics mitigation. SVG works as a controlled current source providing any kind of current waveform in real time.When the load generates inductive or capacitive current, it makes load current lagging or leading the voltage. An SVG detects the phase angle difference and injects in real time leading or lagging current into the electric power systems, making the phase angle of the current almost the same as that of the voltage, bringing fundamental power factor to unity.
Features: Step less operation: Static VAR Generator (SVG) is the ultimate answer to power quality problems caused by low power factor and reactive power demand with step less operations as per requirement for a wide range of segments and applications.
Quick Feedback and action:The SVG utilises a high speed three level inverter that reacts to changes in reactive power, exchanging corrective reactive power into the system. Full correction is made in 3/4 of a cycle.
Leading power factor correction:UPS, solar inverters, Loads with low power factor: Motors, cables, lightly loaded transformers, lighting. These loads, who tends to leading power factor.
SVG will correct the lagging as well as leading power factor. Conventional APFC/RTPFC will only correct the lagging power factor.
