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...
IEC vs IEEE Standards for Active Harmonic Filters Explore key differences between IEC 61000 and IEEE 519 standards for Active Power Filters (APF), including harmonic limits, testing protocols, and adaptive solutions. Discover YT Electric’s globally compliant APF systems. Why Dual Compliance Matters for APF in Global Projects? Modern power quality challenges require activ...
Both Passive Power Factor Correction(PPFC) and Active Power Factor Correction(APFC) are used to improve power factor and reduce reactive power, but they differ in complexity, cost, and performance. Passive Power Factor Correction (PPFC) Method: Uses passive components (capacitors, reactors, or filters) to compensate for reactive power. Types of Passive PFC: A. Capacitor Ba...
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)....
