Location of single line-to-ground faults on distribution feeders using voltage measurements
(2006-12-01)
This paper proposes a dedicated algorithm for lation of single line-to-ground faults in distribution systems. The proposed algorithm uses voltage and current phasors measured at the substation level, voltage magnitudes ...
Dynamic DC-Link Voltage Control of Back to Back Modular Multilevel Converter for Drive Applications
(IEEE, 2019)
In this work a dynamic control of the dc-link voltage in a hybrid Back-to-Back (BtB) Modular Multilevel Converter for medium-voltage drive applications is presented. The proposed control scheme relates the speed of the ...
Hybrid Method to Assess Sensitive Process Interruption Costs Due to Faults in Electric Power Distribution Networks
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)

Resonant (P+RES) controller applied to voltage source inverter with minimum DC link capacitor
(2011-12-28)
Voltage source inverters use large electrolytic capacitors in order to decouple the energy between the utility and the load, keeping the DC link voltage constant. Decreasing the capacitance reduces the distortion in the ...

Voltage sag assessment using an extended fault positions method and Monte Carlo simulation
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-01-01)
In this article, we propose an extended fault positions method combined with the Monte Carlo method to evaluate voltage sags. The distribution function SARFI is obtained by taking into account the randomness of (i) location ...
Classification of voltage sags according to the severity of the effects on the induction motor
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-03-01)
In this paper, symmetrical and unsymmetrical voltage sags are classified according to the severity of the effects produced on the behavior of induction motors, using the double-cage rotor model. The analyzed variables are: ...
Voltage Stability Assessment of Radial Distribution Systems Including Optimal Allocation of Distributed Generators
Assessment of power systems voltage stability is considered an important assignment for the operation and planning of power system. In this paper, a voltage stability study using Continuous Power Flow (CPF) is introduced ...
