1. Summary Due to the advantages of simple control and low cost of uncontrolled rectifying converter, it is widely used in switching power supply, frequency converter and other equipment. However, this kind of converter will inject a large amount of harmonic current into the power grid, and increasingly become the most important harmonic source in the power grid. Most of the frequency converters o...
What is Total Harmonic Distortion & How AHF Can Help In this blog post, we will explore what THDi is and why it is important. We will also discuss how Active Harmonic Filters (AHFs) can help reduce problems caused by harmonics. What is Total Harmonic Distortion (THDi)? Total Harmonic Distortion (THDi) represents the distortion in an electrical current waveform because of the presence of harmon...
How does Static var generator reduce kva demand? A Static Var Generator (SVG) reduces kVA demand through the following mechanisms: 1. Dynamic Reactive Power Compensation Real-Time Adjustment: SVG provide real-time reactive power support by injecting or absorbing reactive power (kVAR) as needed. This dynamic response helps maintain voltage levels, reducing the overall kVA demand. 2. Improved Power ...
Harmonics: Not a Problem Unless They Become One Harmonics in modern power systems are now considered “the new normal” due to the widespread use of non-linear loads. While harmonics can lead to issues such as overheating, overloads, and resonance, they don’t always pose immediate problems. The key is understanding when harmonics are actually causing harm. When Should You Ac...
Introduction of power conversion system A Power Conversion System (PCS) refers to a set of devices and processes that convert electrical energy from one form to another in various applications, including renewable energy, energy storage systems, electric vehicles, and industrial applications. It plays a crucial role in managing and optimizing energy flow, ensuring efficiency, and maintaining power...
Abstract This article introduces a method for short-term forecasting of photovoltaic (PV) generation. The proposed method falls within the category of physical methods and relies on numerical weather forecasts. Forecasting was achieved by utilizing a PV source model in the OpenDSS software. The calculated results were compared to actual measurements taken from operational PV micro-installations. A...
Overcurrent Protection: Fundamentals and Applications Overcurrent protection is essential for the safe and reliable operation of electrical systems and equipment. It helps prevent damage to devices and reduces the risk of electrical fires and other safety incidents. This article will cover the basics of overcurrent protection, its main types, working principles, and applications across various fie...
Effects of harmonics on electronic equipment Power Quality and Its Importance Power quality refers to the stability and performance of an electrical system.
