Integrated planning of electric power distribution networks
(2009-12-01)
In this work, a heuristic model for integrated planning of primary distribution network and secondary distribution circuits is proposed. A Tabu Search (TS) algorithm is employed to solve the planning of primary distribution ...
Analysis of voltage and short-circuit current on photovoltaic generation dominated distribution systems
(2018-06-25)
This paper proposes an integrated impact analysis of photovoltaic generation in the voltage profile and the short-circuit level in secondary distribution networks. The analysis is to verify the level of voltage in consumer ...
Evaluating the effects of high penetrations of roof-top wind turbines on secondary distribution circuits
(Ieee, 2006-01-01)
Incentives for using wind power and the increasing price of energy might generate in a relatively short time a scenario where low voltage customers opt to install roof-top wind turbines. This paper focuses on evaluating ...

Inverter-fed linear asynchronous machine
(1998-12-01)
The behaviors of an arc-shaped stator induction machine (the sector-motor) and a disc-secondary linear induction motor are analyzed in this work for different values of the frequency. Variable frequency is produced by a ...
Bioextraction of copper from printed circuit boards: influence of initial concentration of ferrous iron
(TMSSan Antonio, Texas, 2013)
Printed circuit boards are found in all electric and electronic equipment and are particulary problematic to recycle because of the heterogeneous mix of organic material, metals, and fiberglass. Additionally, printed ...
Optimization of multipulse converters with delta and Y-differential connections
(2009-12-01)
This work presents a study regarding the optimization of multipulse converters. A general expression for the connection (Δ or Y) for both 12 and 18-pulses is obtained and describes the output voltages on the secondary ...
An isolated DC-DC converter with +/-220V balanced outputs for telecom systems
(2001-12-01)
This work proposes a new strategy to improve the double-output DC-to-DC converter. The isolated full-bridge topology is zero-voltage switched (ZVS) and the pulse-width modulation is phase-shifted (PS-PWM). The high-frequency ...
