EVALUATION OF THE IMPACT OF THE ELECTRIC POWER QUALITY IN THE INDUSTRIAL PRODUCTION: PROPOSAL OF METHODOLOGY

Abstract

Power Quality is a field of studies that has recently been object of concern and research.. Power Quality indicators of the supply of Electric Energy used nowadays are defined by means of traditional ratings of evaluation and do not included concepts and procedures from a global perspective of the electric systems that take into account the economic impacts of the loss of the Quality of the Electric power in the regional industrial areas. Thus, one verifies that nowadays the present methodology needs improvement for better decision-making in its management. The aim of the present work is to propose a new "Evaluation Methodology of the Electric Power Quality in the Industrial Production" with the new technical and economic indicators that take in consideration the costs associated to the loss of this quality. Some researches were accomplished in some industries in Brazil's Northeast, in the states of Paraíba, Pernambuco, Alagoas, Sergipe and Bahia.
