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...
Can Active Power Filters (APF) and Static Var Generators (SVG) Provide Significant Solutions for the Rapidly Growing EV Charging Pile/Station Market? As global EV ownership surges, power quality issues in charging infrastructure have become increasingly prominent. As nonlinear loads, EV chargers generate harmonic pollution and reactive power fluctuations during operation, leading to grid vo...
In our increasingly electrified world, the quality of electric power is more critical than ever. Whether we realize it or not, electric power quality affects virtually every aspect of our lives—from the functionality of household appliances and the reliability of our smartphones, to the stability of industrial systems and the safety of hospitals. Poor power quality can lead to equipment malf...
