Application Scope of SVG Static Synchronization Compensator
1. SVG series static synchronous compensators have been successfully applied to metallurgy, new energy sources, power transmission and transformation industries.
Rail Transit: Traction Locomotive
Power generation: wind farm, photovoltaic power plant, thermal power plant
Metallurgy: electric arc furnace, refining furnace, rolling mill
Power transmission and transformation: substation


Working Principle of SVG
1. SVG uses IGBT, a high-power power electronic device, which can be turned off. It is composed of several inverters connected in series. The main circuit topology includes star connection and corner connection.
2. Satellite connection topology is suitable for conventional reactive power compensation and harmonic filtering, while corner connection topology is suitable for comprehensive reactive power, harmonic, negative sequence and flicker compensation.
