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)....
Source-Grid-Load-Storage (SGLS) is a novel coordinated operational model for energy and power systems. It aims to build a flexible, efficient, and clean modern power system by integrating energy production, transmission, consumption, and storage. This concept represents a key solution to challenges such as large-scale renewable energy integration and dynamic power supply-demand balance amid t...
From data centers in Frankfurt to EV charging stations in Southeast Asia, Active Harmonic Filters (AHFs) are rapidly becoming the gold standard for solving one of the most overlooked yet costly problems in industrial power systems—harmonics. Modern electrical loads such as variable frequency drives, inverters, and switching power supplies generate non-linear current waveforms, resulting in h...
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 power systems, Power Factor (PF) is often seen as just a technical term. But for factories, data centers, and other industrial users, a low power factor can directly translate to higher electricity bills, lower equipment efficiency, and even penalties from the utility. So what exactly is power factor? How does it impact your energy cost? And how can you improve it effectively? Let’...
