O GNL como mecanismo de flexibilização no fornecimento de gás natural para geração termelétrica no Amazonas
(Universidade Federal do Pará, 2020-09-14) PEREIRA, Salony Aquino; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079
Convergence between the natural gas and electricity markets is increasing as a result of the increasing liberalization of the natural gas and electricity markets, as well as increasing environmental constraints, projections of global natural gas demand indicate strong growth, especially in the electricity generation segment. The transport of natural gas in its liquefied form, LNG (Liquefied Natural Gas), is an important agent for this convergence as well as for the increasing global integration of the natural gas and electricity markets. It is observed that there is a supply of natural gas to be used, but is currently poorly distributed in the Amazon. Considering that there is only one natural gas supplier to Amazonas and conditions are limited for both new business and high investment price, it is important to evaluate new alternatives for natural gas supply and LNG supply is an interesting alternative. The present study evaluates the feasibility of an alternative model based on the possibilities of LNG supply, acting as a mechanism to flexibilize the supply of natural gas and ensuring a better use of electricity generation capacity today installed in the Amazon.

Implementação de um sistema supervisório em unidades geradoras de energia elétrica de sistemas isolados instalados em municípios do estado do Amazonas
(Universidade Federal do Pará, 2021-08-30) SILVA, Jefferson Emilio Maciel da; LEITE, Jandecy Cabral; http://lattes.cnpq.br/7279183940171317
This master's dissertation consists of an exploratory research carried out by monitoring the maintenance activities carried out in the Thermoelectric Power Plants installed in the cities of the State of Amazonas, with the objective of implementing a monitoring system for electrical quantities coming from engines, also called Engenies Electric Power. This is a field research with qualitative approaches, taking into account the implementation of an automated system to capture the variations in electrical quantities (Voltage, Current, Power and Power Factor) of these energy generating units. The capture of these data, which are the variations of electrical quantities, occurs with the use of PLC, transducers, Modem, among other equipment, which are stored in a database (computer) that using a Supervisory System modeled for this purpose, providing the visualization of these data, in real time, in a friendly and interactive interface. From the monitoring of these data, via a Supervisory System, and with the use of data manipulation tools from the SCADA system, an interface for the generation of graphics was modeled, which significantly contributed to the interpretation of these data. And in addition, make it available remotely, to everyone involved in the activities of the plants, thus being able to access the Supervisory System from anywhere in the world, through the internet.
