What are the differences between SVG and capacitors？ SVG (Static Var Generator) and traditional capacitor banks serve the common purpose of reactive power compensation in electrical power systems, yet they diverge considerably in their operational mechanisms, performance attributes, and adaptability. Below is an elaboration comparing these methodologies: 1. Operation: - ...
CT position of SVG and and capacitor banks SVG (Static Var Generators) and capacitor bank can work together in a power system to provide a comprehensive solution for reactive power compensation and power quality improvement. Here’s how they can complement each other: Combined Use of SVG and Capacitor Banks 1. Complementary Functions Capacitor Banks: Provide bulk reactive power compensation. ...
Resonance and Active Harmonic Filters Resonance in power systems can lead to significant issues such as harmonic amplification, overvoltages, and equipment damage. Active Harmonic Filters (AHFs) play a crucial role in mitigating harmonic distortion and preventing resonance. Understanding how resonance occurs and how AHF can be used to manage it is key to maintaining a stable and efficient electric...
How to calculate transformer efficiency? Transformers, like all electrical devices, experience some power losses during operation. While ideal transformers would be lossless, real-world transformers incur power losses that manifest as heat, necessitating cooling solutions. The main types of power losses in transformers are resistive loss, eddy current loss, hysteresis loss, and flux loss. R...
India's power distribution companies Discoms are responsible for the supply and distribution of energy to a variety of consumers (industrial, commercial, agriculture, domestic, etc.). This is also, according to the Brooking Institute, the weakest link in the power ecosystem from both a financial and operational sustainability perspective. The quality of power quality Of course, the provision of po...
General Reference – Power Quality Assessment Procedure Abstract: Power quality is a frequently used term that means different things to different people. Common power quality problems occur because of the mismatch between a utility's power and the customer's energy-using equipment, leading to faulty operation. Some common power issues are sudden changes in voltage, electrical d...
ABSTRACT Distribution network operators face increasing challenges related to Power Quality (PQ). EDP Distribuição in Portugal has developed a comprehensive PQ monitoring program to address these challenges. This paper outlines the state-of-the-art PQ monitoring platform and methodology used by EDP, and presents results from monitoring HV/MV and MV/LV substations. Improvement actions...
Introduction Power quality is a general term used to describe the compatibility between connected equipment and its electrical supply. The supply system can be affected by changes to the frequency or amplitude of the voltage, the balance between phases on a three-phase system, and distortion levels of the original signals. The characteristics that are important and what can be tolerated by the con...
