Stabilizing Renewable Energy Projects with SVG and AHF – An Engineer’s Perspective In the rapidly growing renewable energy sector, ensuring grid stability is one of the biggest challenges. Solar and wind power, while sustainable, are inherently variable. Voltage fluctuations and harmonic distortions are common issues that can compromise both safety and efficiency of power transmission....
The Problem: Variable Speed Drives Generate Harmonics What is a Variable Speed Drive (VSD/VFD)?A Variable Speed Drive (VSD), also commonly called a Variable Frequency Drive (VFD) or Adjustable Speed Drive (ASD), is an electronic device that controls the speed and torque of an AC electric motor by varying the motor's input frequency and voltage. How Do They Cause Harmonics?The internal design of a ...
As the world accelerates toward cleaner energy, the grid is being asked to carry far more than it was ever designed for. Solar parks, wind farms, and EV charging stations are connecting at record speed. On the surface, this looks like a straightforward victory for decarbonization. Yet behind the scenes, one invisible factor quietly determines whether this energy transition can succeed: power quali...
1. Why Do SVGs Generate Harmonics? Unlike ideal components, the real-world power electronic switches (IGBTs) in an SVG do not switch sinusoidally. They use Pulse Width Modulation (PWM) to synthesize a sinusoidal output current. This switching action is the primary source of harmonics. PWM Switching Frequency Harmonics: The output voltage of the SVG's H-Bridge inverters is a series of high-fre...
Have you ever been troubled by these frustrating issues? Production lines in your factory halting without warning, causing massive financial losses? Lights in your office building flickering inexplicably, servers restarting frequently, putting data at risk? Receiving shockingly high electricity bills every month, with unexplained "penalty" charges? Electrical equipment overheating, lifespan shorte...
Part 1: Power Distribution - The "Highway System" for Electricity Power distribution is the final stage in the delivery of electricity from the generation plant to the end-user (homes, businesses, industries). Think of it as the local and regional road network that brings goods from a central warehouse to your doorstep. Key Components of a Distribution System: Distribution Substations: Receiv...
Power Problems? Two Tools That Fix Them for Good Does your facility have any of these issues?---- Energy bills that are too high. Machines that run hotter than they should. Production lines that stop unexpectedly. Often, the problem isn't your equipment. The problem is the quality of the electricity that powers them. It's like giving an athlete dirty water to drink—performance w...
As industries expand and renewable energy grows, good power quality is essential for stable and efficient electrical systems. Issues like voltage drops, low power factor, and unstable loads can reduce performance and cause shutdowns. Our company offers full R&D, manufacturing, and sales support for high-performance Static Var Generators (SVGs). Our SVG products provide fast, accurate, and inte...
