When electric utilities experience a breakdown, there is not only a problem for end consumers who are faced with loss of electricity, but also...
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
Wi-Fi, a WLAN conforming to IEEE 802.11b is emerging as a good replacement for LAN. It allows people to log onto the Internet and receive e-mails on the move. WiMAX an 802.16 wireless metropolitan-area network with a range of 50 km, facilitates wireless broadband access in metros and rural areas, and is a cost effective alternative to cables... - K S Sidhu
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
The local electrical power supply company imposed restrictions on the operation of the Electric Arc Furnaces, 4 hours each in the morning and evening peak periods. The plant was in loss... - C V Govinda Raju
Power electronics based controllers used in distribution systems are called custom power devices. These devices have been proved to be quite effective in power quality enhancement. They may be of series, shunt and series-shunt or series-series type – depending upon their connection in the circuit... - D K Tanti, MK Verma, Brijesh Singh, O N Mehrotra
Energy meter is the key component of supply system whose reliable functioning is very essential for accurate registering, controlling and monitoring, of power consumption...- Deepa Warudkar, Priyamvada Chandel, B.A.Sawale, Neha Gupta, Shilpa Singh Yadav
