Due to the growing power quality & cost reduction requirements of commercial and industrial installations, the need for static Var generators has grown.
An SVG is a power electronic device that helps regulate the reactive power flow within a power system. SVGs use IGBTs to control the flow of reactive power. Their incredible ability to provide inductive and capacitive reactive power makes them suitable for neutralizing voltage sags and harmonics caused by nonlinear loads.
Working Principle of Static Var Generators (SVGs)
A Static VAR Generator (SVG) is an electrical device used to regulate and stabilize voltage in power systems by providing reactive power compensation. It helps improve power quality and efficiency by dynamically adjusting reactive power to maintain optimal voltage levels. SVGs are commonly used in industrial and commercial applications to manage power factor and reduce electrical losses.
Once there is a voltage sag or harmonic distortion in the AC system, the SVG detects the perturbation and injects reactive power into the system to counterbalance the perturbation. SVG can provide both inductive and capacitive reactive power depending on the requirement.
Advantages of Static Var Generator
- Step less reactive power compensation

Applications of Static Var Generators
Static Var Generators (SVGs) has several applications, including:
- Industrial facilities: Industrial plants use SVGs to compensate for power quality issues from large motors and other nonlinear loads. The nonlinear loads cause voltage fluctuations that may further create harmonic distortions that negatively impact other equipment attempting to function on an electrical network. SVG provides compensation for reactive power and keeps the voltage levels stable.
- Wind farms: It can also regulate the reactive power flow by wind farms to improve the grid’s stability. A wind turbine generates electricity by basically changing wind energy into electrical energy. However, the output from the wind turbines can be unpredictable, and this reactive power flow may further cause instability in the grid. SVGs compensate for the reactive power flow and help stabilize the grid.
- Data centers: Static Var Generators enhance data center performance by stabilizing voltage, improving power quality, and managing reactive power. This ensures reliable operation, reduces energy losses, and protects sensitive equipment from power fluctuations, enhancing overall efficiency and uptime.
- Solar: Static Var Generators optimize solar power systems by regulating voltage, improving power quality, and managing reactive power. This enhances grid stability, reduces energy losses, and ensures efficient integration of solar energy into the electrical grid.
