A First approach on the new transmission system in northern Brazil
This article shows an analysis of the electrical parameters of a three-phase transmission line section using a relatively new design for steel towers characterized by 280 meters high. These main features, the height of the ...
Determination and statistical treatment of short-circuit currents for faults on the lines of networks of 440 kV CESP system
The distribution of short-circuit current is investigated by means of two methods, one direct and the other analytic; both methods consider uniform probability distribution of line faults. In the direct method, the procedure ...
Transmission Asset Maintenance Programming Optimization - The Brazilian Electric System Case
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2015)
Consumer behavior after the Brazilian power rationing in 2001
In June 2001, after a dry period, the level of the water reservoirs in Brazil was below their operational levels. This situation, combined with other historical factors, led the country into a period of power rationing. ...
Investigation of the relationship between load and loss factors for a Brazilian electric utility
With the considerable increase of the losses in electric utilities of developing countries, such as Brazil, there is an investigation for loss calculation methodologies, considering both technical (inherent of the system) ...
A novel single-phase hpf hybrid rectifier suitable for front-end trolleybus systems
This paper proposal presents the development and the experimental analysis of a new single-phase hybrid rectifier structure with high power factor (PF) and low harmonic distortion of current (THDI), suitable for application ...
