SVG Dynamic Reactive Power Compensation Cabinet
The ADSVG series high-voltage dynamic reactive power compensation system, centered on IGBT technology, provides rapid and continuous supply of capacitive or inductive reactive power. It ensures constant reactive power, voltage, and power factor at monitoring points, guaranteeing stable, efficient, and optimal operation of power systems. When installed near specialized loads (such as electric arc furnaces) in distribution networks, medium and small-capacity ADSVG units significantly improve power quality at load connections to the public grid. These improvements include enhanced power factor, balanced three-phase voltage, controlled voltage flicker and fluctuations, and effective harmonic pollution mitigation.
Application scope and function
The ADSVG series products are widely used in industries such as petrochemicals, power systems, metallurgy, electrified railways, and urban construction. They provide high-quality and reliable reactive power compensation and filtering solutions for various equipment including asynchronous motors, transformers, thyristor converters, frequency converters, induction furnaces, lighting systems, electric arc furnaces, electric locomotives, hoists, cranes, stamping machines, cranes, elevators, wind turbines, welding machines, resistance furnaces, and quartz melting furnaces.
ADSVG system architecture
The main circuit of ADSVG series products adopts chain topology structure, modular structure design, and star and triangle connection mode to achieve relatively high cost performance under different capacities, which not only guarantees the effectiveness of user investment, but also guarantees the stability, high efficiency and excellent operation of the power system.
The ADSVG series control cabinets and power cabinets utilize fiber optic isolation technology for signal transmission, achieving reliable voltage isolation between high and low voltage systems. The structural design of the ADSVG series has been significantly optimized for easier maintenance. The control cabinets undergo rigorous anti-interference treatment to ensure the control system remains unaffected by high-voltage main circuits. The upgraded power modules (units) enable more compact power cabinet layouts, substantially saving equipment space for users and reducing overall investment costs.
The ADSVG product series consists of three core components: control cabinets, power cabinets, and reactor cabinets. The power cabinet design achieves significant standardization, enabling easy capacity expansion and enhanced stability. Each voltage level unit comprises three integrated modules: a control cabinet, a power cabinet, and a reactor cabinet (or air-core reactor).
What functions can be implemented:
1. It can enhance the power transmission capacity, reduce power loss, and compensate the reactive power to more than 0.98;
2. Reduce the reactive power fluctuation and harmonic of the traction transmission bracket device;
3. Control flicker, stabilize the voltage of the power grid and balance the three-phase system;
4. Change the damping characteristics of the system and improve the stability of the system
5. Stable power supply voltage and centralized compensation for substations that supply power to more medium and low voltage motors;
Commissioning Successful and Smooth Operation: The SVG Dynamic Reactive Power Compensation Cabinet provided by Aodong Electric has been successfully implemented at the metallurgical plant, boosting its power factor to 0.99. Previously subject to continuous penalties, the facility now receives a monthly reward of 30,000 yuan after adopting Aodong's SVG compensation system. This technology proves particularly beneficial for enterprises with significant grid fluctuations, earning high recognition from users.
Aodong Electric Company explains the principle and functions of SVG dynamic reactive power compensation. The technology can compensate both inductive and capacitive reactive power, with continuous adjustment capabilities to boost power factor above 0.99, meeting dynamic reactive compensation requirements during system load variations. It features three-phase imbalance compensation. The device operates as a current source, preventing system resonance issues. Automatic current limiting ensures no overcompensation or undercompensation. Comprehensive protection includes overcurrent, overvoltage, undervoltage, and overtemperature safeguards. The user-friendly interface eliminates common overcompensation concerns. For further details about SVG dynamic reactive power compensation, please contact Aodong Electric at any time.
