With the development of the economy and society, a large number of nonlinear loads have been introduced into the power grid, which has brought a series of power quality issues, such as voltage fluctuations, low power factor on the grid side, unbalanced three-phase voltage, and high harmonic content. As a result, Static Var Generators (SVG) have been introduced both domestically and internationally to address these power quality issues.
SVG Oil Immersed Distribution Transformer
SVG oil-immersed transformers are critical equipment in the power system, particularly in wind and solar photovoltaic power generation systems. They convert grid voltage to a level suitable for the operation of SVG reactive power compensation devices, achieving electrical isolation between high and low voltages and enhancing the system's reliability and stability. These transformers have high impedance and short-circuit resistance, along with optimized harmonic characteristics that help reduce voltage fluctuations and improve power quality.

SVG oil-immersed transformers serve critical functions in electrical power systems, including
1. Reactive Power Compensation: They dynamically adjust reactive power to enhance power factor and overall grid performance.
2. Integration in Renewable Energy Systems: They are used in wind and solar power systems to transform voltage levels and ensure stable operation alongside SVG devices.
3. Stability and Reliability Improvement: By supplying reactive power, they support the grid during extreme conditions, minimizing the risk of outages.
4. Harmonic Mitigation: They help control harmonic distortion caused by nonlinear loads, improving power quality.
5. Electrical Isolation: They provide isolation to prevent noise and interference, safeguarding sensitive equipment.
6. Voltage Regulation: They help maintain stable voltage levels across different loads and conditions.
These transformers are essential for maintaining the efficiency, stability, and quality of power systems, offering a range of benefits from reactive power support to harmonic suppression and electrical isolation.
