FGI’s SVG Solutions: Powering Global Energy Transition with Dynamic Reactive Compensation in 20+ Countries

Amid the global energy transition, China’s power electronics technology is accelerating its international reach. As a leading innovator in dynamic reactive power compensation, FGI has successfully implemented its independently developed SVG series in power system enhancement projects across 20+ countries, including Southeast Asia, the Middle East, and Africa. By leveraging "China Smart Manufacturing," FGI addresses critical global challenges such as grid instability and the efficient integration of renewable energy sources.

Case Study 1: Photovoltaic Power Plant Project in Southeast Asia

Challenge:

In a tropical climate, frequent fluctuations in photovoltaic (PV) output led to severe grid voltage instability. The local utility company required the power factor of the plant to remain at ≥0.98 throughout the year.

Solution:

• Deployed multiple centralized SVG units with customized structural and component designs to withstand high temperature and humidity.
• Implemented multi-unit parallel control technology to ensure seamless coordination among devices.

Results:

• Reduced grid voltage fluctuation from ±15% to within ±2%.
• Improved and stabilized the PV plant’s power factor above 0.99.

Case Study 2: Wind Power Project in Central Asia

Challenge:

The wind power generation was unstable, leading to significant voltage fluctuations. The variations in wind speed and the start-stop operation of turbines caused reactive power imbalances.

Solution:

• Installed a 35kV 40Mvar direct-connected SVG, equipped with filtering functionality to address the site's harmonic distortion issues.

Results:

• Improved the power factor of the wind farm, meeting grid operation requirements.
• Filtered out harmonic currents generated during the wind farm’s operation, preventing interference with nearby sensitive electrical equipment.

Case Study 3: Power Quality Improvement Project at a Metallurgical Plant in the Middle East

Challenge:

The large variable frequency drives (VFDs) and electric arc furnaces generated harmonic content exceeding 30%, with a power factor of only 0.76, affecting the safety of other equipment.

Solution:

• Customized an "SVG + FC" hybrid compensation system.
• Deployed a wide-frequency harmonic detection algorithm (covering 2nd to 50th harmonics).

Results:

• Increased power factor to 0.98.
• Reduced harmonic distortion to <3%.
• The customer replicated the solution across three industrial sites.

Case Study 4: Power Grid Stability Enhancement at a Gold Mine in Africa

Challenge:

Long-distance transmission lines experienced high reactive power losses, with voltage drops of up to 35% at the far end, leading to frequent regional power outages.

Solution:

• Installed an SVG at the end of the transmission line to effectively stabilize the grid voltage.

Results:

• Increased transmission line capacity by 40%, significantly alleviating the local power supply pressure.
