tailieunhanh - POWER QUALITY ISSUES

Nowadays we assist to the increasing of devices and equipments connected to power systems (non-linear loads, industrial rectifiers and inverters, solid-state switching devices, computers, peripheral devices etc). Hence, the parameters of the power supply should be accurately estimated and monitorized. For this purpose have been proposed power quality monitoring systems that are abble to automatically detect and classify disturbances. | POWER QUALITY ISSUES Edited by Ahmed Zobaa Power Quality Issues http 3373 Edited by Ahmed Zobaa Contributors Belkacem Mahdad Bedri Kekezoglu Celal Kocatepe Recep Yumurtaci Oktay Arikan Mustafa Baysal Altug Bozkurt Celal Fadil Kumru Moisés Vidal Ribeiro Zbigniew Hanzelka Soliman Abdel-Hady Soliman Mariacristina Roscia Cristian George Lazaroiu Nicolae Golovanov António Pina Martins Gabriel Gasparesc Jaroslaw Luszcz Patricio Salmerón Alejandro Pérez Joao Luiz Afonso José Gabriel Pinto Henrique Goncalves Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2013 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
