Risk mitigation approaches for improved resilience in distribution networks
(2020-09-28)
traditionally the risk analysis framework comprises two steps: risk assessment and risk mitigation. The tracking of operating conditions for each feeder section of a distribution network using the prediction of hourly risk ...
Determination and statistical treatment of short-circuit currents for faults on the lines of networks of 440 kV CESP system
(1995-12-01)
The distribution of short-circuit current is investigated by means of two methods, one direct and the other analytic; both methods consider uniform probability distribution of line faults. In the direct method, the procedure ...
Defects location in power systems components through a dedicated genetic algorithm
(2004-12-01)
In this work the problem of defects location in power systems is formulated through a binary linear programming (BLP) model based on alarms historical database of control and protection devices from the system control ...
An approach based on neural networks for identification of fault sections in radial distribution systems
(Ieee, 2006-01-01)
The main objective involved with this paper consists of presenting the results obtained from the application of artificial neural networks and statistical tools in the automatic identification and classification process ...
Network reconfiguration and loss allocation in a deregulated environment of distribution systems
(2005-12-14)
Low flexibility and reliability in the operation of radial distribution networks make those systems be constructed with extra equipment as sectionalising switches in order to reconfigure the network, so the operation quality ...
Advanced network reconfiguration system applied to CEMIG-D system
(2013-08-26)
In the network reconfiguration context, the challenge nowadays is to improve the system in order to get intelligent systems that are able to monitor the network and produce refined information to support the operator ...
Optimized allocation of sectionalizing switches and control and protection devices for reliability indices improvement in distribution systems
(2004-12-01)
Reliability of power supply is related, among other factors, to the control and protection devices allocation in feeders of distribution systems. In this way, optimized allocation of sectionalizing switches and protection ...
Estimation of parameters for faulted transposed transmission lines
(Ieee, 2018-01-01)
This paper presents a method to estimate transmission line parameters for transposed lines from faulted current and voltage measurements at the line's terminals, in the time domain. The measurements are transformed to the ...
