Why is SVG important in photovoltaic power stations?
SVG plays an irreplaceable role in photovoltaic power stations. It significantly improves the energy efficiency and grid quality of photovoltaic power stations by improving power factor, reducing losses, stabilizing voltage, suppressing harmonics and improving grid stability.
What is a static VAR generator (SVG)?
SVG (Static Var Generator) plays a vital role in photovoltaic power stations. It significantly improves the energy efficiency, grid stability and power quality of photovoltaic power stations by quickly and accurately providing or absorbing reactive power.
How does SVG work?
SVG can detect the voltage and current status of the power grid in real time, quickly compensate for reactive power, and make the power factor of the power station close to 1, that is, to achieve "unity power factor".
Why should we use SVG reactive power compensation devices?
Therefore, it is even more necessary to use SVG reactive power compensation devices reasonably to improve the transmission stability and capacity of the new power system, avoid voltage fluctuations and harm, and ensure low harmonic content, fast response speed, and high reliability in the output of photovoltaic power plants.
What are the advantages of SVG?
