Understanding the Principles of Active Harmonic Filters (AHF) Active Harmonic Filters (AHF) are devices used to improve power quality. They reduce harmonic distortions and compensate for reactive power in electrical systems. The main idea behind AHF is to detect and counteract unwanted harmonic currents and reactive power. This helps make the power system more efficient and stable. Let&rsqu...

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...
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...
Reactive power charges and power factor assessments are common in electricity billing, especially for industrial and commercial consumers. Here's a detailed explanation: 1. Reactive Power Charge Reactive power (measured in kVARh) is the power consumed by inductive or capacitive loads (e.g., motors, transformers, fluorescent lights) that do not perform actual work but are necessary for maintai...
The 4 quadrants of reactive power refer to the different combinations of active (real) power (P) and reactive power (Q) flow in an AC electrical system. These quadrants are defined based on whether power is being generated or consumed and whether the system is supplying or absorbing reactive power. Four Quadrants of Reactive Power: The quadrants are categorized based on th...
