Aodong Electric ADSVG Railway Field Application Case
Compensation capacity: -0.3M var ~ + 0.3M var
System voltage: 380V
Load characteristics: The on-site load is mainly lighting lamps, and a large number of electronic ballasts are used to produce harmonics.
Compensation effect: After the ADSVG is put into operation, the compensation rate of harmonic current reaches 80%, which meets the assessment requirements of the national standard — — Harmonics of Public Power Grid (GB/T 14549-1993).
Aodong ADSVG enhances grid stability, boosts transmission capacity, mitigates reactive power surges, filters harmonics, and balances three-phase power systems.
◆ Improve the stability of line transmission.
◆ Maintain the receiving end voltage and strengthen the voltage stability of the system.
◆ Compensate the reactive power of the system, improve the power factor, reduce the line loss, save energy and reduce consumption.
◆ Suppress voltage fluctuations and flicker.
◆ Suppress three-phase imbalance.
SVG can quickly compensate the negative sequence current caused by load imbalance, always ensure the balance of three-phase current flowing into the grid, and greatly improve the power quality of power supply and consumption.

The technical specifications of ADSVG from Aodong Electric are as follows:
Selection size:
Selection Notes: Typically, voltage and compensation capacity, industry, installation location, cooling method, and harmonic content must be provided.
Voltage: 6kV, 10kV, 35kV
Compensation capacity: ±0.1 Mvar to ±200 Mvar. If you cannot provide the exact capacity, you can provide the following materials:
1. Primary power supply system diagram;
2. Multiple busbars, evaluation points (where is the current sampling?)
3. Tap the transformer nameplate
4. Electricity bills of the power supply bureau in the past three months.
Our technicians can calculate the required compensation capacity for you; if conditions permit, our technicians can carry the equipment to the site for measurement.
Industry: Traditional industry (petroleum chemical industry, power system, metallurgy, electrified railway, urban construction, etc.) and new energy industry (photovoltaic, wind power, energy storage, etc.)
Installation location: Outdoor or indoor. If there is indoor installation space, indoor installation is possible. If indoor installation space is insufficient, outdoor installation is required.
Cooling method: Wind cooling or water cooling. For large capacity or harsh environments (high wind, high humidity, high salt fog, high corrosion, high condensation, etc.) and high noise requirements, when conventional air cooling cannot meet the on-site environmental requirements, water cooling should be selected.
Harmonic content: ADSVG can simultaneously achieve reactive power compensation and harmonic mitigation. However, in scenarios with high harmonic content, a FC high-voltage filter compensation device is required to effectively remove harmonics.
Aodong Electric's ADSVG series products are widely used in petrochemical, power systems, metallurgy, electrified railways, urban construction, and related industries. These solutions provide high-quality, reliable reactive power compensation and filtering for various equipment including asynchronous motors, transformers, thyristor converters, frequency converters, induction furnaces, lighting systems, arc furnaces, electric locomotives, hoists, cranes, stamping machines, lifting equipment, wind turbines, welding machines, resistance furnaces, and quartz melting furnaces.
The ADSVG series products from Aodong Electric can enhance power transmission capacity, reduce energy loss, compensate reactive power, control harmonics, suppress flicker, stabilize grid voltage, balance three-phase systems, modify system damping characteristics, and improve system stability.
