Product Overview
The Kaich Active Harmonic Filter is an innovative solution for power quality issues in industrial settings. It utilizes IGBT inverter-based 3-level topology technology to provide fast and real-time harmonic mitigation. This active harmonic filter offers a range of functions including selectable priority, reactive power compensation, load balancing, and harmonic filtering.
How it Works
The Active Harmonic Filter (AHF) is connected in parallel to the power system. It collects real-time power system data through an external sampling current transformer (CT). The internal digital signal processor (DSP) reacts quickly using an intelligent fast Fourier transform (FFT) algorithm to calculate the required compensation current value. It then sends a command to the IGBT to dynamically adjust the switching frequency and optimize the performance of the AHF.
The AHF generates a reverse amplification of the same value current to offset the harmonic current, effectively reducing the harmonic distortion for each order. This process ensures that the total harmonic distortion ratio is kept below 5%, in accordance with the IEEE 519 standard.
Key Features
1. Selectable Priority Function: The active harmonic filter allows users to prioritize specific functions such as reactive power compensation, load balancing, or harmonic filtering based on their unique power quality requirements.
2. Real-time Data Collection: The AHF collects power system data in real-time through an external sampling current transformer (CT). This ensures accurate and up-to-date information for optimal performance.
3. Intelligent FFT Algorithm: The internal digital signal processor (DSP) utilizes an intelligent fast Fourier transform (FFT) algorithm to calculate the required compensation current value. This advanced algorithm enables precise and efficient harmonic mitigation.
4. Dynamic Switching Frequency: The AHF dynamically adjusts the switching frequency of the IGBT to optimize performance and ensure effective harmonic reduction. This feature allows for adaptability to changing power system conditions.
5. Total Harmonic Distortion Reduction: By generating a reverse amplification of the same value current, the AHF effectively offsets harmonic currents and reduces the total harmonic distortion ratio to below 5%, meeting the standards set by IEEE 519.
