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....
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...
SVG Parallel Operation Test via CAN Communication Test Objective This test aimed to verify the performance and stability of multiple SVG (Static Var Generator) units operating in parallel via CAN communication when internal CTs are not used. Specifically, eight SVG modules were tested to evaluate their operation, communication reliability, and reactive power compensation consistency under CAN-base...
Jiangsu Non Woven was founded in 2002 and has a 20-year history of non-woven fabric production, which is a high-quality manufacturer of high-end non-woven fabrics integrating R&D, production and after-sales. The factory is located in Zhitang Town, Changshu City, Jiangsu Province, a famous non-woven fabric production base in China, covering an area of 15,000 square meters, with a daily producti...
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...
