Análise da partida de motores de indução em sistemas isolados de geração síncrona

Abstract

Power Quality is an issue that has assumed paramount importance in the sector of energy production in Brazil and abroad. This is due in principle to the great demand for electric energy and the need to better control the generation, transmission and distribution of this product. The biggest problems for this purpose are the occurrences of electrical disturbances that impair performance, service life of equipment and devices, produce disruptions and damage industrial processes and domestic network. Voltage transients on the line, caused by activation of electrical machinery, causing voltage sags relevant, is the most prominent theme of this dissertation work. Among the most important electrical machines used by the industry, is the Phase Induction Motor (MIT). Therefore, a study prepared and consistent on the effects of activation of these machines can reveal important aspects and define how we can improve the quality of energy, taking decisions about costs and control, knowledge, and many other aspects. This paper talks about tests made with scientific methodology and based on computer simulations, substantiated by experiments carried out in laboratories at the University Santa Cecilia (Santos, SP) and supervised by Prof.. Dr. Luciano Martins, FEELT of the UFU (Uberlândia, MG), with the collaboration of Prof. Engineers. Dr. Silverio Santos y Penin (CDMC and UNISANTA, SP) and Prof. Dr. Edval Deoboni (EMAE, SP). Tests of MIT drives with the help of measuring equipment and several comparisons with computational simulations.
