ABSTRACT GASPAR, R. R. Developing an electrical power system of a mobile electron beam accelerator to treatment of industrial wastewaters and effluents. 2018. 62 p. Dissertação (Mestrado em Tecnologia Nuclear) -Instituto de Pesquisas Energéticas e Nucleares -IPEN-CNEN/SP. São Paulo. The treatment of wastewater and industrial effluents by electron beam irradiation is a promising technique, however, not very widespread in Brazilian territory. The design and a construction of a mobile unit containing an electron beam accelerator of 700 KeV and 20kW, by the Nuclear and Energy Research Institute (IPEN) is innovative to demonstrate the effects and positive results of this technology. The aim is to move the mobile unit to several companies with interest in liquid waste treatment, and connect to the industry electrical system and start the ionization treatment process through electron beam. The mobile unit's connection to the local electrical system can be a challenge in behalf of the great diversity of voltages and distances involved, as well as the large injections of harmonic content generated by the electron beam accelerator that can affect sensitive loads in the industrial system. In this work, an analysis was made of the power system of the mobile unit, regarding interruption capacity, selectivity protection and adequate short circuit levels in order to assure a greater reliability in the operation. At the end, the control panel of the mobile unit, simulations and measurements were carried out at the 1.5 MeV and 37.5 kW electron beam accelerator, installed at the Intensive Radiation Technology Center, which demonstrated the necessity of applying of a filter to reduce the measured harmonic distortion.
