Today, energy saving is the target of all industries across the world, where India too is not an exception. This is a story of lowering the energy consumption by 63%...

Introduction The Intelligent Load Management System (ILMS) is a modern approach to industrial power management, designed to keep operations running without disruption. By...

Power factor compensation and harmonic filtration in integrated steel plants is a tool to reduce stress in electrical system. The paper focuses on energy efficiency issues and advantages with compensation and harmonic filtration. The paper presents comparative study of compensation requirement in various steel plant units. It would be interesting to find that requirement is the most in Rolling Mills, BOF, CCP, BF & Sinter Plant. In fact the entire steel plant is energy guzzler and with advent of drives, automation and precision requirement, fanning out electrical system stress has become more important and crucial… - Anil Kumar Choudhary, Md Mobinul Islam

Introduction The journey to modern electrical system reliability starts with careful evaluation of existing infrastructure and extends through smart retrofitting, precise integration, and...

Micro-grids include low voltage distribution systems with distributed energy resources and controllable loads that can operate in medium voltage grid connected mode or in islanded mode. It provides environmental and economic benefits for end-user, customers, utilities and society. However, their implementation creates great technical challenges, such as the protection. Micro-grid system has bidirectional power flows, which make traditional fault insufficient. An algorithm combining of cumulative sum and power flow method is found to be simple and faster for detecting micro-grid faults in both modes of operation... - Vikrant J. Majarikar, K.S. Swarup
