FGI Static Var Generator scheme helps overseas new energy development and industrial upgrading
Under the wave of global energy transformation, China's power electronics technology is accelerating to the world. As a technology leader in the field of dynamic reactive power compensation, FGI has successfully applied its independently developed SVG series products to power system upgrade projects in more than 20 countries in Southeast Asia, the Middle East, Africa, etc., to solve global challenges such as power grid instability and new energy consumption difficulties with "smart manufacturing in China".
Case 1 Photovoltaic power plant project in a Southeast Asian country
Challenge
In tropical climate, photovoltaic output fluctuates frequently, grid voltage fluctuates seriously, and the local power company requires the power factor of the power station to be ≥0.98 throughout the year.
Solution
Install multiple sets of centralized SVG, design the product structure and devices specifically, adapt to the environment of high temperature and high humidity, and adopt multi-machine parallel control technology to ensure coordination and cooperation between devices.
Effect
The voltage fluctuation of the junction point is reduced from ±15% to within ±2%, which improves the power factor of the photovoltaic power station and stabilizes above 0.99.
Case 2 Wind power project in a Central Asian country
Challenge
Wind power generation is unstable, the voltage fluctuation is large, and the reactive power imbalance is caused by wind speed fluctuation and fan start and stop.
Solution
Installed 35kV 40Mvar direct-hanging SVG, equipped with filtering function to solve the problem of field harmonics exceeding the standard.
Effect
Improve the power factor of wind farm to meet the requirements of power grid operation; The harmonic current generated in the process of wind farm power generation is filtered to avoid the interference of harmonics to the surrounding sensitive electrical equipment.
Case 3 Power quality improvement project of a metallurgical plant in the Middle East
Challenge
Large frequency converters and electric arc furnaces cause the harmonic content to exceed 30%, and the power factor is only 0.76, affecting the safety of other equipment.
Solution
Customize the "SVG+FC" hybrid compensation system, and configure the harmonic detection algorithm in the broadband domain (full coverage of 2-50 harmonics).
Effect
The power factor was increased to 0.98, the harmonic distortion rate was < 3%, and the customer copied the solution to its three industrial bases.
Case 4 Improved power grid stability of a gold mine in a country in Africa
Challenge
The long distance transmission line has high reactive power loss, terminal voltage drop up to 35%, and regional outage frequently.
Solution
Install SVG at the end of the line to effectively stabilize the power grid voltage.
Effect
The transmission capacity of the line is increased by 40%, which greatly reduces the pressure on local power supply.
FGI Static Var Generator product superiority
SVG compensation is faster, reactive power response time is less than 5ms, can achieve accurate and fast compensation for field load changes.
SVG has a variety of compensation modes, which can compensate reactive power, voltage, power factor and other indicators.
The operating efficiency of the equipment can reach more than 99%, and the loss is small.
Products through IEC, IEEE and other international certification, can be operated at -40℃~+55℃, high altitude conditions.
From equatorial rainforests to desert oil fields, from emerging markets to power grids in developed countries, FGI has always taken "making electricity better" as its mission and continues to export smart power solutions. By the end of 2024, FGI has served more than 150 key customers around the world and built a bridge between China's intelligent manufacturing and the world's energy revolution with core technology.
