Power Factor Correction Methods Efficient energy management has become a cornerstone of modern industries and commercial facilities. Among the various strategies to optimize energy usage, Power Factor Correction (PFC) stands out as a critical approach for reducing energy losses, improving power quality, and minimizing costs. Reactive power compensation methods play a vital role in achieving...
Before diving into the architecture and types of battery energy storage systems (BESS), it is essential to familiarize ourselves with key terminology commonly used in this field. Various parameters are crucial in describing the behavior and performance of BESS. · Capacity [Ah]: This represents the amount of electric charge the system can supply to a connected load while maintaining an accep...
What are Reactive Power and Reactive Power compensation？ Reactive power is a key part of AC electrical systems—it’s the energy that flows back and forth between the power source and the load. Unlike active power, which does the actual work like powering lights or running machines, reactive power doesn’t directly get used up. But it plays a crucial role in keeping voltage levels s...
Harmonics & VFDs: Causes, Solutions, and Key Insights How VFDs Cause Harmonic Issues Variable Frequency Drives (VFDs) are commonly used to control motor speed and optimize energy consumption in industrial systems. However, VFDs work as nonlinear loads. This means they draw currents that are not smooth, even if the supply voltage is a perfect sine wave. This happens because VFDs change AC power...
Power quality metering for industrial efficiency In today's competitive industrial landscape, ensuring an uninterrupted, stable, and efficient power supply is essential. Power quality issues such as voltage fluctuations, harmonic distortion, and poor power factor can lead to significant operational downtime, costly equipment repairs, and reduced energy efficiency. Power quality metering is a criti...
Abstract: Utility power system harmonic problems can often be solved using a comprehensive approach including site surveys, harmonic measurements, and computer simulations. This case study presents the results for a commercial facility harmonic evaluation. The simulations were completed using the PSCAD program. The analysis evaluates the effects of transformer connections to determine the har...
Introduction Power quality refers to the characteristics of electric power supplied to end users, particularly its ability to ensure the proper functioning of electrical devices. With the increasing use of sensitive equipment such as programmable logic controllers, variable frequency drives (VFDs), and computers in modern industries, the tolerance for power disturbances such as voltage dips, swell...
Addressing Power Quality Issues in Russian Electrical Networks The power quality in Russian electrical networks fails to meet established regulatory standards, causing significant challenges across various sectors of society. Economic losses are among the most severe consequences. As the digital economy evolves, power quality requirements intensify due to the increasing reliance on sen...
How to Measure Power Quality Efficient energy use is a key goal for organizations and institutions that generate, transmit, and distribute electricity. Improving efficiency requires better power quality, otherwise, it can harm electrical systems. Measuring power quality is essential to identify and fix these issues. Accurate measurements from correct points are critical. I. Introduction Mos...
Access to electricity is expanding globally, but challenges persist. While more people are gaining connections to power grids, issues such as frequent outages and poor power quality remain widespread, particularly in developing regions. Poor power quality, often characterized by voltage fluctuations and inadequate electrical performance, affects millions of users. It hampers their ability to use e...
