This work aims to present the effects of lightning performance indexes in VDC (substation of Vila do Conde), located in the northern region, in the State of Pará, in the period from 2005 to 2013, establishing the relationship between the weather information provided by the SIPAM and data provided by the center of operations for Eletronorte in order to perform and determine the harmful effects of atmospheric discharges, which are responsible for the intensification of interruptions in the supply of electricity.The analysis is restricted to the area of expertise of Eletronorte (substation of Vila do Conde) which has much of its power transmission Lines installed in northern Brazil. The results show that the incidence of lightning can cause direct and indirect surges in transmission lines and substations of high power. In this context justifies the study of efficient forms of prevention, being one of the purposes of this work, which aims to provide general information concerning the effects produced by the action of atmospheric discharges in substations of the power sector as the quality of energy, in particular in the VDC – Eletrobrás System-Eletronorte.

Simulador de uma subestação elétrica para ensino de princípios básicos de eletricidade
(Universidade Federal do Pará, 2017-02-08) SILVA, Hudson Afonso Batista da; RIBEIRO FILHO, Manoel; http://lattes.cnpq.br/9329438229733907
This work presents the design and implementation of a simulator, composed of a part in software and a part in hardware, to help the teacher in the teaching of electricity principles and basic operation of a substation, using as a case of use the Eletronorte substation in the Municipality of Marabá located in the Southeast region of the state of Pará. For the development of the simulator were used together the Unity platform in 2D and a mini circuit using Arduino. The Simulator underwent classroom evaluations with students and the teacher and proved to be a tool capable of assisting in the teaching of basic principles of electricity and basic operation of a substation.
