SVG for for Dynamic Reactive Power Compensation

SVG as a dynamic reactive power source, uses high-speed computing components such as DSP/IGBT, combined with ultra precision control programs, to track real-time changes in grid current, and increase the PF value to 0.99 within 15ms.
The widespread application of large capacity nonlinear loads and impulse loads such as power electronic equipment in transmission and distribution grids and industrial users has brought serious power quality problems. SVG can significantly improve the power quality at the connection point between loads and the public power grid, such as improving power factor, overcoming three-phase imbalance, eliminating voltage flicker and voltage fluctuations, and suppressing harmonic pollution.
The SVG dynamic reactive power compensation device produced by our company has advantages in response speed, stable grid voltage, reduced system losses, increased transmission force, improved transient voltage limit, reduced harmonics, and reduced footprint.The development of SVG relies on our company's strong technical strength, fully utilizing our comprehensive research, design, manufacturing, and testing capabilities. Our company has close academic connections and technical cooperation with well-known research institutions and electrical companies at home and abroad. We are willing to work together with our customers to improve the power quality of the power grid with advanced technology and high-quality products, and contribute to energy conservation, consumption reduction, and safe production in the power generation, supply, and consumption sectors.
