Active Harmonic Filters (AHFs) are widely used in buildings to mitigate harmonic distortion caused by non-linear loads, ensuring power quality, energy efficiency, and compliance with standards like IEEE 519 and IEC 61000-3-6. Here are key applications of AHFs in buildings: 1. Office Buildings & Commercial Complexes Loads: LED lighting, VFDs (HVAC systems), elevators, UPS systems...
Can Active Power Filters (APF) and Static Var Generators (SVG) Provide Significant Solutions for the Rapidly Growing EV Charging Pile/Station Market? As global EV ownership surges, power quality issues in charging infrastructure have become increasingly prominent. As nonlinear loads, EV chargers generate harmonic pollution and reactive power fluctuations during operation, leading to grid vo...
Modern industry runs on precision—yet harmonic distortions, voltage fluctuations, and reactive power imbalances remain costly adversaries. These silent disruptors erode efficiency, inflate energy bills, and jeopardize compliance. Enter the YTPQC-AHF Active Power Filter (APF): an intelligent solution engineered not just to mitigate power quality issues, but to eliminate them at thei...
Design of Power Quality Optimization Scheme for Wind Farms I. Typical Power Quality Issues in Wind Farms Voltage Fluctuations & Flicker Sudden wind speed changes → Power fluctuations → Bus voltage variations (especially in weak grids) Harmonics & Interharmonics Converter switching frequencies (2-6kHz) generate characteristic harmonics (e.g., 5th, 7th, 11th, 13th) Tower shadow eff...
Have you ever heard of "harmonics" in electrical systems? If not, it’s time to pay attention—because these invisible distortions could be silently eroding efficiency, damaging equipment, and inflating energy costs. But what are harmonics, exactly? Think of electrical current as a symphony: ideal current flows smoothly in a single "note" (frequency). Harmonics are unwan...
Harmonics are a critical yet often overlooked phenomenon in electrical systems. They represent distortions in the ideal sinusoidal waveform of voltage or current, occurring at frequencies that are integer multiples of the fundamental power frequency (e.g., 50 Hz or 60 Hz). While harmonics are inherent in modern power systems, their uncontrolled presence can lead to severe operational and financial...
Essential Steps for Sizing Active Harmonic Filters 1. ✅ Conduct Harmonic Analysis: Begin by performing a thorough harmonic assessment. Identify the specific harmonic frequencies pres...
