“…The problem of corona when it occurs in transmission lines insulators can cause losses in the transmission and, mainly, untimely shutdowns in the lines [1]. These non-scheduled shutdowns of affect on the way the operation of electrical systems and can even generate the shutdown of large populated areas.…”

This paper presents a computational package and equipment with the purpose to detect corona problems of insulators in transmission lines. Low-cost equipment detects presence of corona, via acoustic emissions and stores them in a memory. These data are processed by computer programs. The applicability of this equipment is immediate for any transmission company, because the perfect understanding of the operational capacity of its lines in various operating conditions and climate change allows for a safer operation with improvement of quality of service provided.

“…The techniques like the expert systems and searching techniques make possible to explore a new world through computer program with non-algorithm structures (said intelligent). Intelligent systems have been to create computational programs to help or train students, operators or engineers [6]. It should be noticed that the intelligent systems tend to be complementary to the existing systems, and not to substitute them.…”

This paper has developed a methodology for testing of substation functional circuits from the utility company. This methodology allows making all possible combinations of the functional circuits, aiming to find whether there is any fault, bad operation or project mistake in these circuits. The fundamental idea is that this set of tests, automatically made by a computer package, provide the elimination of any type of wrong action of these circuits, which generate the undesirable system breakdown and problems regarding the rate of steady power supply. This joint project has been developed between EDP-Bandeirante Power System and Federal University of Itajuba with practical and education purposes. In the final version of the paper a complete example of a EDP-Bandeirante substation will be added.

“…Resuming the system restoration process issue, the restoration is defined as the process of changing the open/closed status of switches, loss reduction, load balancing and restoration (Lambert-Torres et al, 1997). This is a decision-making problem of combinatory nature, subject to optimization and system building characteristics constraints.…”
