What is the function of SVG?

Static Var Generator (SVG) is a power electronics-based device that provides dynamic reactive power compensation in various applications. In solar power plant applications, SVGs are used to regulate and control the flow of reactive power in the electrical system. Reactive power is an important aspect of power systems that is necessary for voltage control and maintaining system stability. It consists of three basic functional parts: sensors, controller and compensation output module. By analyzing the current information measured by the outer CT or PT sensors, its controller will send Var compensation power to help regulate voltage levels and power factor in the electrical energy system, ensuring efficient power transmission and stable operation. By rapidly absorbing or injecting reactive power as required, SVGs mitigate voltage fluctuations, minimize line losses, and improve overall power quality. Overall, SVGs play a crucial role in reactive power compensation in solar power plant applications, ensuring optimal performance and grid stability.
