The use of current transformers for noise detection due to sparking in insulators strings in high voltage transmission lines
(2010-12-31)
In a general way, in an electric power utility the current transformers (CT) are used to measurement and protection of transmission lines (TL) 1 The Power Line Carriers systems (PLC) are used for communication between ...
Electrical consumers data clustering through optimum-path forest
(2011-12-21)
Non-technical losses identification has been paramount in the last decade. Since we have datasets with hundreds of legal and illegal profiles, one may have a method to group data into subprofiles in order to minimize the ...
Mathematical decomposition technique applied to the probabilistic power flow problem
(2011-05-31)
In this paper a framework based on the decomposition of the first-order optimality conditions is described and applied to solve the Probabilistic Power Flow (PPF) problem in a coordinated but decentralized way in the context ...
Influence of the supply of reactive power in the calculation of the transfer capability
(2004-12-01)
This paper presents some initial concepts for including reactive power in linear methods for computing Available Transfer Capability (ATC). It is proposed an approximation for the reactive power flows computation that uses ...
