AHF, SVG and SCADA

AUTOMATION SYSTEMS

Real-Time Power Quality Protection and Intelligent Filtering
 

Active Harmonic Filter (AHF) systems are intelligent and dynamic filtering solutions that detect harmonic distortions caused by nonlinear loads in the power grid in real time and suppress them by injecting counter-current.
 

Enersolix AHF solutions effectively eliminate harmonic distortion in the power grid using advanced digital signal processing (DSP) and real-time control algorithms. They reduce the system’s THD level, minimize heating in transformers and cables, extend equipment lifespan, and improve power quality.
 

Why an Active Harmonic Filter?

While traditional passive filter systems can only address specific frequencies, active filters dynamically analyze the constantly changing harmonic profile and suppress it with an instantaneous counter-frequency. As a result, the system continuously delivers clean power even if the load profile changes.

Static VAr Generators (SVGs) are high-speed power electronics solutions that respond to reactive power compensation needs within milliseconds, especially in environments with rapidly changing inductive or capacitive loads.

Enersolix SVG systems operate entirely with IGBT-based inverter technology.
Unlike classic capacitor-based compensation systems, it instantly detects sudden changes in load and dynamically generates or consumes reactive power according to the system's needs.

How does it work?

SVG systems continuously monitor the instantaneous power factor, voltage, and current angle in the grid. Depending on the needs;

  • If there is an inductive load, it provides capacitive power.

  • If there is a capacitive load, it will behave inductively.

And it accomplishes all of this contactlessly, silently, and without vibration, thanks to its IGBT-controlled inverter structure.

Areas of application:

  • CNC machine lines

  • High-speed automation systems

  • Data centers, metro substations

  • Arc furnaces and steel production facilities

  • Wind and solar energy systems

  • Networks containing inductive/capacitive unbalanced loads

Technical Specifications (Example):

  • Voltage Level: 400V / 690V (LV); 6kV / 10kV (for MV applications)

  • Response Time: <15 ms

  • Power Range: 30kVAr – 2000kVAr (expandable with modular design)

  • Technology: IGBT-based inverter

  • Compliance: IEEE 519, IEC 61000-4-7, IEC 62589

  • Cooling: Fan-cooled or liquid-cooled.

  • Monitoring: HMI panel / Modbus / Ethernet / SCADA integration

Advantages:

  • Real-time and precise compensation.

  • There is no risk of resonance.

  • Stable operation even under overload conditions.

  • High performance during sudden load changes.

  • Compact design, modular structure, maintenance-free solution.

  • Fully compatible with SCADA and energy monitoring systems.

Enersolix SVG solutions not only go beyond classic compensation, but also make your entire energy system intelligent, flexible and robust.
