1. Introduction In light of high energy usage, environmental pollution, and rising fossil fuel prices, current dependence on internal combustion engine (ICE) technology employed in vehicles should be reduced, and the widespread use of electric vehicles (EVs) as the transportation of choice in 20 to 30 years' time should be increased. It is estimated that EV vehicle penetration will increase gradua...
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...
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...
Effects of harmonics on electronic equipment Power Quality and Its Importance Power quality refers to the stability and performance of an electrical system. Specialized instruments measure it in three-phase electrical systems by assessing various factors. Addressing power quality issues can help your facility save on energy costs and protect equipment from potential damage. The first step in evalu...
