Product Description
As one of the professional and high quality STATCOM manufacturers, The FGI high voltage Static Var Generator (SVG) has more than 20 years of experience in R&D, FGI has developed and manufactured high voltage dynamic reactive power compensation device Static Synchronous Compensator (STATCOM) in 2006 to improve grid stability, increase transmission capacity, eliminate reactive shock, filter out harmonics and balance three-phase power grid.
FDSVG series as the static synchronous var compensator can be widely used in petrochemical, power system, metallurgy, electrified railway, urban construction and other industries, for various asynchronous motors, transformers, thyristor converters, inverters, and other equipment to provide high-quality, high-reliability reactive power compensation and filtering solutions.
FDSVG series products as the reactive power compensator, it provides fast dynamic reactive power compensation and harmonic filtering for power grid and electrical loads. It also can effectively improve transit stability of power grid voltage, suppress bus voltage flicker, compensate unbalanced loads, filter the harmonic and reduce power loss.
