Power Quality Solutions: The Role of AHF and SVG Modern power systems face increasing power quality issues such as harmonic distortion, voltage fluctuations, and reactive power imbalance. These problems can damage equipment and reduce system efficiency. Traditional solutions like capacitor banks and passive filters have limitations in speed, accuracy, and harmonic adaptability. ...
The Definition of Active Harmonic Filters (AHF) An Active Harmonic Filter (AHF) is an important device that improves power quality. Its main jobs are to reduce harmonic distortion in power systems and to adjust reactive power as needed. The AHF connects to the grid in parallel and performs real-time detection of harmonic components in the grid. A power converter creates a compensation current. Thi...
An Active Harmonic Filter (AHF) is a dynamic power quality management device. It based on power electronics technology, primarily designed to eliminate harmonic currents and compensate reactive power in electrical systems. Its core operation revolves around real-time detection, calculation, and dynamic compensation of harmonic distortions. So what situation do we need this equipment? Metallurgy In...
Both Passive Power Factor Correction(PPFC) and Active Power Factor Correction(APFC) are used to improve power factor and reduce reactive power, but they differ in complexity, cost, and performance. Passive Power Factor Correction (PPFC) Method: Uses passive components (capacitors, reactors, or filters) to compensate for reactive power. Types of Passive PFC: A. Capacitor Ba...
Harmonic Distortion Explained: Dangers of High Levels & How to Protect Your Systems Harmonic distortion is a hidden threat in modern electrical systems. While it doesn't get the same attention as power outages or surges, excessive harmonic distortion can quietly damage equipment, reduce energy efficiency, and cost businesses thousands. Understanding what harmonic distortion is, why it happens,...
In electrical engineering, three-phase power systems are essential for efficiently distributing electricity across various sectors, including industrial, commercial, and residential environments. Two of the most commonly used systems are the three-phase four-wire (3P4W) and three-phase three-wire (3P3W) configurations. Understanding their key differences is crucial for selecting the appropr...
In recent years, people have become more and more aware of environmental protection. At the same time, many want to reduce their reliance on traditional power sources. This is why home solar power systems, or photovoltaic (environmental protection) systems, have become extremely popular. These amazing systems can convert sunlight into electricity that we can use at home. Not only do they help us c...
Have you ever passed by a factory filled with the hum of machinery or a supermarket that’s open around the clock? If so, you’ve witnessed the hidden essence that powers modern industry: a steady, dependable stream of electricity. But consider this - what occurs when solar panels produce an excess of energy on a sunny day, or when the power grid collapses during a fierce storm? This is ...
