SVC (Static Var Compensator)

A Static Var Compensator (SVC) is a device used in electric power systems to regulate voltage and improve stability. It quickly adjusts reactive power—necessary for maintaining voltage levels—by adding or absorbing electrical energy without moving parts, using electronic components like thyristors. This helps prevent voltage fluctuations, enhances the reliability of power supply, and allows the grid to accommodate variable demands or power flows efficiently. Essentially, an SVC acts as a smart, fast-acting voltage manager that keeps the electricity system balanced and stable.
