Comprehensive Guide to AHF Calculation and Installation

Active harmonic filter (AHF) play a crucial role in mitigating harmonic distortions and improving power quality in electrical systems. This comprehensive guide outlines the step-by-step process for AHF calculation, installation, parameter settings, and performance monitoring.

Power Quality Audit:

Prior to AHF installation, conduct a thorough power quality audit to identify harmonic distortion levels, voltage fluctuations, and other power quality issues in the electrical system. This audit helps determine the specific harmonic frequencies and magnitudes that require mitigation.

AHF Sizing Calculation:

Based on the findings of the power quality audit, perform AHF sizing calculations to determine the required capacity of the AHF system. Consider factors such as the magnitude of harmonic currents, system voltage, load characteristics, and permissible distortion levels. Enjoypowers’ experienced engineers can assist in accurately sizing AHF modules for optimal performance.

Wiring and Parameter Settings:

Once the AHF system is sized appropriately, proceed with the installation and wiring of AHF modules according to manufacturer guidelines. Configure parameters such as harmonic current thresholds, control modes, and compensation settings based on the specific requirements of the electrical system.

Choose the CT installation location:

• Load-side (open-loop): CTs measure load currents directly.
• Grid-side (closed-loop): CTs monitor overall grid currents.
• For parallel AHF modules, share the same CTs and consider adding a separate set at the AHF output for precise load harmonic current calculation.

Enjoypowers provides user-friendly interfaces and comprehensive manuals to facilitate seamless parameter settings.

Installation and Commissioning

Follow these steps:

• Connect power and control lines.
• Start the AHF breaker.
• Monitor AHF performance and verify harmonic reduction.
• Regularly inspect and maintain the AHF.

Remember, a well-installed and properly tuned AHF ensures optimal power quality and efficient operation. Happy harmonics management!

Monitoring AHF Performance:

After installation, continuously monitor the performance of the AHF system to ensure effective harmonic mitigation and optimal operation. Utilize monitoring tools and software provided by Enjoypowers to track harmonic distortion levels, power factor improvements, and system stability in real-time. Regularly analyze monitoring data to identify any deviations from expected performance and take corrective actions as necessary.
