Paper Title
Fault Detecting In High Voltage Transmission Line Based On Protection Scheme
Abstract
In this paper, based on the transient
harmonic protection scheme for identifying faults
in two terminals of HVDC transmission line. The
response of the transient harmonic current in the
voltage source converter HVDC transmission line
is analyzed under various faults. The VSC based
HVDC system is very attractive anoption for bulk
power transmission over long or short distances
and the grid integration of renewable energy
sources in existingtransmission and distribution
systems. In this method, harmonic components of
the voltage signals are extracted through Discrete
Fourier Transform (DFT) at two terminal of
HVDC transmission line. The two most important
factors are involving fault resistance and location.
It can detect fault in rectifier side and inverter
side of two terminal of HVDC transmission line
accurately and quickly. All of these simulations
are done using Matlab/Simulink.
