Overview Features Technical Parameter Downloads

Static Var Generators (SVG) are dynamic reactive power compensation devices based on voltage source converters. They inject controllable capacitive or inductive reactive current into the power grid to achieve rapid and continuous automatic reactive power compensation, effectively improving the power factor, reducing line losses, and stabilizing system voltage. Zhiguang's SVG products cover a range of 6~35kV and 0.3~150Mvar, providing comprehensive power quality management solutions.

1. Rapid Response and Flicker Suppression:

Response time ≤ 4ms, enabling real-time tracking of grid fluctuations, effectively suppressing voltage flicker, and ensuring grid-connected stability of the energy storage system.


2. High-Efficiency Operation and Low Harmonic Injection:

Device efficiency ≥ 99%, output current harmonic distortion rate < 2%, providing both reactive power compensation and harmonic suppression and three-phase balance functions.


3. Strong Heat Dissipation and High Reliability:

Utilizing a patented air-cooling and water-cooling system design, supporting wide temperature range operation from -40℃ to 45℃, featuring a comprehensive fault self-diagnosis and isolation protection mechanism, and supporting bypass operation without shutdown.


4. Multifunctional Control Modes:

Supports multiple modes including constant power factor, constant voltage, constant reactive power, and integrated voltage and reactive power control, possessing high and low temperature ride-through capabilities to adapt to the complex operating environment of new energy power plants.


5. Modularization and Expandability:

Supports multi-unit parallel operation, flexibly expanding capacity to meet the customized needs of power plants of different sizes.
