The Ultimate Solution for Power Quality ---SVG & AHF

Reliable power quality is key for efficient work in today's factories and businesses. Two main issues often come up: harmonic distortion and wasted reactive power. Here are two advanced technologies can solve these problems: Active Harmonic Filter (AHF) and Static Var Generator (SVG). They help reduce risks and make power systems work better.

The Main Problems: Harmonics and Reactive Power

Harmonics are unwanted electrical frequencies. Examples include variable frequency drives (VFDs), LED lights, welding machines, and data center cooling systems. These extra frequencies mess up the normal smooth power wave. This increases energy loss, damages sensitive equipment, and makes systems less efficient.

Industry research shows that harmonic distortion can raise basic current losses by 5-10%. In the end, this leads to more than 10% of total energy waste.

Reactive power is another issue.

These loads include motors and transformers. Reactive power doesn’t do useful work. But it puts a lot of pressure

Active Harmonic Filter (AHF): Fixing Harmonics Precisely

An Active Harmonic Filter is an advanced device. It can quickly detect and cancel harmonic currents in real time.

These include 5th-generation IGBT or silicon carbide components. The device injects counter currents. These currents cancel out harmonics. This keeps the grid current smooth and regular.

Key Benefits of AHF

• High Efficiency & Low Losses: Modern AHF systems work effiency could up to 99%. They lose 33% less heat than older models. For example, a 150A AHF can save up to 12,972 kWh of energy every year.
• Covers Most Harmonics: AHF can filter out harmonics from the 2nd to the 50th order. This meets strict international rules like IEEE 519.
• Fast Response: AHF's response time is less than 20 microseconds. This makes AHF handle changing loads even the load change fast. For example, welding machines and solar power plants have harmonics that change quickly.
• Small and Scalable: Modular AHF units are 63% smaller than traditional systems. This saves valuable space for installation. So they’re suitable for small businesses and large factories alike.

Static Var Generator (SVG): Managing Reactive Power

A Static Var Generator is the best tool for managing reactive power. This keeps the power factor stable (usually above 0.95) and maintains steady voltage levels. Unlike traditional capacitor banks (which are slow and prone to resonance), SVG provides precise, fast compensation for changing loads.

Key Benefits of SVG

• Four-Quadrant Compensation: SVG can supply two types of reactive power—inductive power and capacitive power. This makes it perfect for complex loads.
• Fast Response and Voltage Stability: SVG responds in milliseconds. It quickly fixes voltage drops and surges. This protects sensitive equipment. Examples include data center servers and precision manufacturing tools.
• Energy Savings and Cost Cuts: SVG improves the power factor to nearly 1. This eliminates penalties from power companies. It also reduces energy loss in transformers and cables. In factories, this can lower energy bills by 5-10%.
• Widely Applicable: SVG works well in harsh environments. These include high-temperature areas and dusty factories.

AHF + SVG: Working Together for Better Power Quality

When AHF and SVG work together, they create a complete power quality management system.

AHF removes harmonics that can damage SVG performance. This helps AHF work more efficiently.

This combination is especially useful in places with mixed loads. For example, factories with VFDs, motors, and solar arrays have both harmonic and reactive power problems.

Active Harmonic Filter and Static Var Generator are more than just power quality devices. They reduce energy costs, make equipment last longer, ensure compliance with rules, and improve reliability.

Whether you run a solar power plant, data center, factory, or commercial building, AHF and SVG deliver real value. They solve the root causes of power in-efficiency.
