Photovoltaic Power Quality: Prevent Penalties via Power Factor Management Introduction More factories and businesses now use solar power systems. But these systems can cause power quality problems. A big issue is low power factor. Power companies charge extra fees for low power factor. This article explains why solar systems hurt power factor and how YT Electric’s SVGs solve this problem. &n...
Think of our power grid like a giant Jenga tower. As we add more wind turbines and solar panels (the green blocks), the tower becomes wobblier. This happens because sunshine and wind change like mood swings. One minute your solar panels are pumping out power during a cloudless noon, the next they’re napping when a storm rolls in. This makes the entire electricity system feel like a weak Wi-F...
Analysis of 3 Different Power Factor Correction Solutions: Capacitors, SVG, and AHF In today’s industrial and commercial environments, ensuring power quality is more than just good practice—it’s a necessity. Poor power quality can lead to equipment malfunctions, increased utility costs, and downtime. One major aspect of power quality is the power factor—a measure of ho...
China Power Quality Issues: Impacts, Costs, and Advanced Solutions In the rapidly evolving landscape of China's power sector, power quality issues have emerged as a critical challenge, demanding immediate attention and effective solutions. This article conducts a comprehensive analysis of the impacts, costs, and advanced equipment solutions related to power quality in China, drawing insight...
The combination of a Static VAR Generator (SVG) and Thyristor-Switched Capacitor (TSC) creates a high-performance hybrid reactive power compensation system. This setup leverages the fast dynamic response of the SVG with the cost-effective bulk compensation capability of TSC. How SVG + TSC Works SVG (Static VAR Generator) Uses a voltage-source converter (VSC) with IGBT...
What is "HT sensing" in reactive power compensation? In a typical HT sensing and low-compensation scheme: HT sensing: The system samples voltage and current on the high-voltage side (e.g., 10kV) using CTs and PTs. Low-side compensation: The actual compensation—either reactive power support (SVG/capacitors) or harmonic filtering (AHF)—is implemented on the low-voltage side (e.g., 400V)....
Why Capacitors Are the Preferred Choice for Reactive Power Compensation When it comes to low-voltage reactive power compensation, the conversation usually narrows down to two options: capacitor banks and Static Var Generators. Ask around, and you’ll likely hear one common reason why capacitors remain popular:“They’re cheaper.” That’s true—but the real answer goe...
In Poland, reactive power management is governed by grid codes and regulations set by the Transmission System Operator (PSE - Polskie Sieci Elektroenergetyczne) and Distribution System Operators (DSOs). The policies aim to ensure grid stability, minimize losses, and maintain efficient power flow. 1. Reactive Power Requirements in Poland A. General Power Factor (PF) Standards St...
