Product Overview

SVG (Static Var Generator) is an advanced reactive power compensation device based on power electronics technology. It is designed to dynamically adjust reactive power in power systems, significantly enhancing grid stability and improving overall power quality.

Working Principle:

The system utilizes a voltage source inverter (VSC) and DC capacitors. Using high-frequency switching devices like IGBTs, it detects reactive power demand in real-time. By generating a synchronized AC voltage with adjustable phases, it quickly injects or absorbs reactive power (capacitive or inductive) to maintain balance.

Core Technical Features

Fast Response: Response time is ≤10ms, significantly faster than traditional SVC systems.
Continuously Adjustable: Smooth reactive output adjustment within a range of -100% to +100%.
Low Harmonic Pollution: Advanced PWM modulation ensures low output harmonic content (THD < 3%).
Compact Design: Eliminates the need for large-capacity reactors or capacitors, reducing the overall footprint.
High Adaptability: Performs reliably in environments with voltage fluctuations, imbalance, and harmonics.

Frequently Asked Questions

What is the main advantage of SVG over traditional SVC?

SVG provides much faster response times (≤10ms) and can continuously adjust reactive power from fully inductive to fully capacitive. It also has a much smaller footprint as it doesn't require large filter banks.

How does SVG handle harmonic distortion?

By using high-frequency PWM (Pulse Width Modulation) technology, the SVG produces a very clean output with Total Harmonic Distortion (THD) of less than 3%, helping to clean up the power grid.

What cooling methods are available for these units?

Depending on the installation environment and capacity requirements, we offer both forced air cooling and highly efficient water cooling systems.

Is the system compatible with different grid frequencies?

Yes, the system is designed to operate on both 50Hz and 60Hz power systems, making it suitable for international applications.

What is the typical response time of the generator?

The system features an ultra-fast response time of less than 5ms for the control loop and a total system response of ≤10ms, ensuring immediate stability during voltage dips.

Can the SVG assist with Low Voltage Ride Through (LVRT)?

Yes, the device is designed to support the grid during faults, including Low Voltage Ride Through capabilities down to 0PU for up to 150ms.
