Wall-mounted Static Var Generator

The Geya Wall-mounted Static Var Generator is a new type of power electronic device designed for dynamically suppressing harmonics, compensating reactive power, and regulating three-phase imbalance. It can extract the harmonic and reactive currents from the load current through sampling transformers, actively output and control the magnitude, frequency, and phase of the output current, and respond quickly to cancel out the corresponding current in the load, achieving dynamic tracking compensation.

Wall-mounted Static Var Generator Highlight

• Efficient Compensation: Adjust current, frequency, and phase in real-time.

• Flexible Configuration: Connect up to 8 units in parallel.

• Smart Monitoring: Monitor remotely with RS485 and Modbus.

• Durable Design: Resist interference and perform in harsh conditions.

FAQ

1. How to select static var generator?

1.Reactive Power Need: Identify the reactive power required for load and voltage control.

2.System Voltage: Match the SVG with your system's voltage level for efficient operation.

3.Response Time: Ensure the SVG offers quick, precise voltage stabilization.

4.Harmonic Emissions: Choose an SVG with low distortion if your system has high harmonics.

5.Power Quality: Consider other issues like flicker and voltage sags, and add filters if needed.

6.Size and Space: Check that the SVG fits the installation area without issues.

7.Cost and Maintenance: Evaluate total costs, including installation, operation, and upkeep.

2. What is the difference between SVG and Statcom?

Both Static VAR Generators (SVGs) and Static Synchronous Compensators (STATCOMs) are used for reactive power compensation, but there are some key differences between them:

· Technology:

• SVG: Uses IGBTs to control reactive power and voltage. Works with voltage-source inverters.

• STATCOM: Uses voltage-source inverters, capacitors, inductors, and fast switching for reactive power control. More complex than SVG.

· Dynamic Performance:

• SVG: Responds faster with precise control over reactive power. Ideal for rapid voltage adjustments.

• STATCOM: Offers solid dynamic performance but may be slower than advanced SVGs. Used in high-voltage systems for voltage regulation.

· Control and Application:

• SVG: Used in distribution networks and medium-sized systems for voltage control and power factor correction.

• STATCOM: Used in large power systems, like transmission lines, for voltage support during disturbances.

· Cost and Complexity:

• SVG: Simpler, cheaper, and easier to implement with fewer components.

• STATCOM: More expensive, complex, and delivers strong performance for critical systems.

Key Difference:

• SVG: Simpler, cheaper, and ideal for small systems or local applications.

• STATCOM: Advanced, pricier, and best for large, high-voltage systems with high demands.
