Power Quality Solution

STATIC VAR GENERATOR :

Automatic power factor correction equipment is broadly applied in INDIAN industry to ensure the electrical network is utilised to its best capacity. The usual form of such power factor correction is an automatic controller that monitors one incoming phase to a plant and switches banks of capacitors to try and maintain a target powerfactor.

The problems with capacitor based automatic power factor correction are vast and varied. It is slow to react to load changes so the system is constantly in a state of over compensation or under compensation. In today’s harmonic rich environments the capacitors suffer with overload. System resonance is a risk and the life expectancy of the system is reduced. Contactor regularly fail and overloaded capacitors leak, presenting a real fire risk.

TREFFER SVG is an entirely new approach to power factor correction. 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. This rapid response provides stable accurate real-time power factor correction without the drawbacks of traditional capacitor based systems. The SVG can continuously adjust reactive power dynamically and bi- directionally (leading or lagging). There is no chance of system resonance and even under low voltage conditions SVG will provide full reactive power compensation. The TREFFER SVG is 100% inverter based so there are no AC capacitors to fail.
