Modern güç sistemlerinde, Doğrusal olmayan yüklerin neden olduğu harmonik bozulma, ekipman arızasına yol açabilir, aşırı ısınma, ve önemli enerji kayıpları. Active Harmonic Filters (AHFs) are increasingly used in industrial and commercial settings to mitigate these issues and maintain power quality. This blog explores the classification and applications of Active Harmonic Filters, particularly focusing on how they vary by application scenario, grid connection method, and other categorization approaches.

Classification Based on Application Scenarios
Active Harmonic Filters are applied across various sectors depending on the load profile, power quality requirements, and harmonic pollution severity.
● Industrial Applications
Factories with heavy machinery, variable frequency drives (VFD'ler), or welding equipment experience high levels of harmonic distortion. AHFs in these settings are designed to dynamically filter a wide range of harmonic frequencies.
● Commercial Applications
Office buildings, Alışveriş Merkezleri, and data centers also generate harmonics due to the extensive use of IT equipment, asansör, and HVAC systems. AHFs help in maintaining compliance with IEEE-519 standards and ensuring the uninterrupted operation of sensitive devices.
● Renewable Energy Integration
Wind and solar systems with power inverters contribute harmonics to the grid. Active filters here are deployed to stabilize voltage and current waveforms, improving the reliability of renewable energy systems.
Classification Based on Grid Connection Methods
The installation approach and location within the electrical network also influence AHF classification:
● Parallel-connected (Shunt) Active Harmonic Filters
These are the most commonly used AHFs. They are installed in parallel with the load and dynamically inject inverse harmonic currents into the grid to cancel out harmonics. The COE Power AHF is a shunt-type filter with real-time compensation capabilities.
● Series-connected Active Filters
Less common but useful in specific applications, these are placed in series with the load. They offer both harmonic mitigation and voltage regulation, but are typically more complex and expensive.
Other Classification Methods
Apart from scenario and grid connection types, AHFs can be further categorized based on:
● Phase Configuration
Three-phase 3-wire
Three-phase 4-wire (suitable for systems with significant neutral current or unbalanced loads)
● Installation Mode
Duvara monte edilmiş
Rack-mounted
Cabinet-integrated
These vary based on space availability and system design preferences.
● Control Strategy
Instantaneous reactive power theory (p-q theory)
Synchronous reference frame theory (dq theory)
The choice of control algorithm affects filtering precision and response speed.
