Determination and statistical treatment of short-circuit currents for faults on the lines of networks of 440 kV CESP system
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 ...
Analysis of voltage and short-circuit current on photovoltaic generation dominated distribution systems
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 ...
Dynamic behavior of a linear induction motor
Although conventional rotating machines have been largely used to drive underground transportation systems, linear induction motors are also being considered for future applications owing to their indisputable advantages. ...
Electric power systems transient stability analysis by neural networks
This work aims to investigate the use of artificial neural networks in the analysis of the transient stability of Electric Power Systems (determination of critical clearing time for short-circuit faults type with electric ...
Second-order model for remote and close-up short-circuit faults currents on DC traction supply
(INST ENGINEERING TECHNOLOGY-IET, 2008)
A technique to calculate the current waveform for both close-up and remote short-circuit faults on DC supplied railways and subways is presented. Exact DC short-circuit current calculation is best performed by sophisticated ...
Investigating effects of neutral wire and grounding in distribution systems with faults
In some applications like fault analysis, fault location, power quality studies, safety analysis, loss analysis, etc., knowing the neutral wire and ground currents and voltages could be of particular interest. In order to ...
