AI automates substation control
(2002-01-01)
An overview is given on the possibility of controlling the status of circuit breakers (CB) in a substations with the use of a knowledge base that relates some of the operation magnitudes, mixing status variables with time ...
Control automatico de un sistema electrico mediante logica difusa
(1999-12-01)
Substitution of fuzzy logic control in an electrical system normally controlled by proportional-integral frequency was studied and analyzed. A linear model of an electrical system, the concepts which govern the theory of ...

Automação de enroladeiras de bobinas de papel: um estudo de caso
(Universidade Tecnológica Federal do ParanáCornelio ProcopioEngenharia Elétrica, 2013)
This study shows how automation resources can help solve problems during the
winding process in a paraffin application machine. The study discusses problems in
the quality of the coils and such problems usually arise ...
Comparative analysis of current and voltage-controlled photovoltaic Maximum Power Point tracking
(2011-12-28)
Maximum Power Point tracking (MPPT) in photovoltaic (PV) systems may be achieved by controlling either the voltage or current of the PV device. There is no consensus in the technical literature about how is the best choice. ...
