Static Var Generator SVG

1. Static Var Generator SVG Overview

CoEpower advanced power factor improvement Series Statischer VAR -Generator (Svg) is an IGBT inverter based 3 level design intelligent PFC product, this SVG statischer VAR -Generator has a wide compensation range from the -1 to +1 lagging, and leading reactive power compensation, three-phase unbalance correction, and harmonic mitigation.

CoEpower special design SVG offers a Target PF working mode, it regulates the PF power factor to the setting value in the HMI in real time, It detects the load current through an external current transformer CT, and then it analyzes the load required reactive power current value by DSP control program in real-time, then generates PWM signal to IGBT inverter to output an opposite direction but same value current to offset the reactive current to meet the target power factor.

3. Main Features

● SVG is designed by the component concept and can make compensation for both capacitive and inductive loads, thus obtaining a compensation effect with the level of PF 0.99 and avoiding over-compensation and under-compensation

● The complete response time of SVG is less than 10 ms and the dynamic response time is less than 50 μs, making SVG a top pick for a fast-changing environment.

● The capacitor that comes with the SVG does not require the installation of a filter bank; therefore resonant amplification will not happen. In addition, as an active compensation device and a current source device adopting such cut-off components as IGBT, SVG wards off resistance from the perspective of mechanism, significantly improving completeness.

● SVG can continuously adjust reactive power dynamically and bi-directionally (-1 to +1); that is to say, SVG can output reactive power constantly in both rated capacitive and rated inductive working conditions and it can make constant compensation in a wide range if combined with a fixed capacitor.

● SVG does not need a large-capacity capacitor or reactor to serve as energy storage elements, and the area it occupies is just half of that occupied by other types of dynamic compensation assemblies with the same capacity, or even a smaller area. Moreover, SVG adopts modular design and cabinet-type installation, which demands only a few efforts in engineering design and installation.

● SVG is designed with an active compensation circuit; therefore, the voltage of the grid has little influence on the compensation capacity. The output of reactive current matches the working condition even when the voltage of the power grid is low.

● SVG has low power loss and needs little maintenance, so chances of resonance overvoltage are pretty low. The service life lasts for over ten years (with an MTBF longer than 100,000 hours).

● High efficiency >97%
