Active Harmonic Filter

Static Var Generator

Automatic Voltage Controller

Active Harmonic Filter

The Active Power Filter (APF) continuously monitors load currents and detects harmonics in real time. It generates compensation currents that are phase-aligned with the load harmonics, effectively neutralizing them. The APF can compensate harmonics ranging from 2 to 50, with compensation rates customizable to meet specific needs. By adjusting the output based on the system's harmonic content, the APF helps ensure optimal power quality and enhances the performance and longevity of electrical equipment.

Working Principle-Active Harmonic Filter

Real-time detection of load current
Harmonic currents are separated step by step based on the specified subharmonic current detection algorithm

According to the set harmonic percentage, the control signal is generated to drive the IGBT output compensation current with the same amplitude and opposite phase of the load harmonic current

Static Var Generator

ARK's static reactive power generators (SVG) are designed for power factor correction and voltage stabilization in power systems. With a reactive power compensation rate of more than 95%, an instantaneous response time of less than 50 us, and a full response time of less than 10 ms, it adapts to a variety of environmental conditions and is suitable for a wide range of applications from industrial processes to power distribution systems. SVG can also perform static voltage and frequency control, providing a comprehensive power quality management solution.

Working Principle-Static Var Generator

The working principle of SVG series static reactive power generator is to place voltage inverters in parallel on the power grid through filters. By adjusting the amplitude and phase of the output voltage on the AC side of the inverter, dynamic accurate compensation is carried out for reactive power in the power grid system. The instantaneous response time is less than 50us and the full response time is less than 10ms, avoiding the occurrence of overcompensating and undercompensating. It is the best solution in the field of reactive power compensation.

Automatic Voltage Controller(AVC)

ARK's Active Voltage Controller (AVC) is an electronic device that regulates and stabilizes the voltage of an electrical power system. It utilizes cutting-edge control algorithms to rapidly detect and correct voltage fluctuations, providing continuous voltage regulation. The AVC is instrumental in applications requiring a stable power supply, such as in data centers and industrial operations, and is also beneficial for integrating renewable energy sources. It optimizes power factor, reduces energy loss, and improves overall system efficiency, ensuring consistent and reliable electrical performance.

Advantages of Automatic Voltage Controller

Voltage stepless adjustment, high adjustment accuracy, the process does not flash off
Using LCL filtering mode, there is no high-frequency harmonic injection load in the output, and no interference to other systems and equipment
The output voltage is adjusted independently by the split phase control
Current limiting output does not exit operation due to overload
Store fault records for 30 fault days
5 Security Protection Improves power supply reliability

Factors to Consider

Load type and requirements

Different loads (such as motors, lighting, sensitive electronic equipment, etc.) have different requirements for voltage stability.

Voltage Range

Determine the voltage range required for AVC support, including maximum and minimum operating voltages.

Voltage regulation capability

AVC should be able to regulate the voltage range, and its response speed to voltage fluctuations.

Power factor correction

If you need to improve the power factor, you should choose an AVC that can provide this function.

Harmonic filtering

If there are harmonic problems in the system, AVC that can reduce or eliminate harmonic effects should be selected.

Continuity

AVC should be able to maintain continuous operation under various grid conditions (including voltage dips and dips).

Efficiency

The operating efficiency of AVC and its impact on the energy consumption of the entire system.

Size and installation

The physical dimensions and installation requirements of the AVC ensure that it fits into the existing space and layout.
