The pursuit of perfect power quality is undergoing a fundamental shift, driven by a new semiconductor material: Silicon Carbide (SiC) . Comparing a traditional Active Harmonic Filter (AHF) with a SiC-based model reveals more than incremental upgrades; it showcases a leap in performance, efficiency, and capability. For decades, traditional AHFs have relied on silicon-based IGBTs. These components w...
The Role of Energy Storage Systems in Off-Grid Power Systems As the need for reliable and sustainable electricity increases worldwide, off-grid power systems are becoming vital. They are important for remote areas, islands, industrial sites, and places with limited access to the grid. Off-grid systems let communities and businesses work without support from national grids. This reduces the ne...
Modern power systems face a hidden threat: resonance. This occurs when harmonic currents from non-linear loads (like VFDs and rectifiers) match the electrical system's natural frequency. The result? Dangerous amplification of harmonic voltages and currents, leading to capacitor failures, overheating, and equipment damage. Traditional passive filters can ironically cause this problem by introducing...
Power Quality Evaluation: The Cornerstone of Stable Solar PV System Operation As solar photovoltaic (PV) systems gain widespread adoption in commercial and industrial settings, interest in financial returns and performance expectations has intensified. However, a critical yet often overlooked aspect throughout the entire lifecycle of solar projects—from planning and installation to oper...
How Does a Static Var Generator Help Stabilize Voltage? Electricity is a very important part of modern life. It powers our homes, schools, hospitals, and factories. For electricity to work safely and efficiently, the voltage must stay stable. If voltage is too high or too low, electrical equipment may not work properly or may even be damaged. In this article, we will explain what voltage is, what ...
Medium-Voltage SVG: A Core Device Empowering Power Quality Optimization in Modern Power Grids With the large-scale grid connection of new energy power generation, the surge in industrial impact loads, and the continuous improvement of users' requirements for power quality, medium-voltage power grids are facing many challenges such as reactive power imbalance, voltage fluctuation, and harmonic poll...
STATCOM : The Core Solution for Power Factor Correction Large-scale solar systems are rapidly integrating into medium and high voltage power grids worldwide. Power factor correction has become a critical requirement for these solar projects. Poor power factor can lead to grid penalties, reduced energy efficiency, and unstable operation. This is where medium and high voltage STATCOM, also kn...
What Is SVG Power Factor Correction? SVG power factor correction is an advanced method of reactive power compensation used in modern electrical systems to maintain a power factor close to 1.0 in real time. Unlike traditional capacitor banks, SVG (Static Var Generator) provides dynamic and precise power factor correction for facilities with non-linear loads such as VFDs, UPS systems, EV chargers, a...
