Abstract: |
Voltage source converter (VSC) based high
voltage direct current (HVDC) transmission is most suited
for the wind farm as it allows flexibility for reactive power
control in multi-terminal transmission lines and transmits
low power over smaller distance. In this work, a novel
method has been proposed to detect the fault, identify the
section of faults and classify the pole of the fault in DC
transmission lines fed from onshore wind farm. In the
proposed scheme, voltage signal from rectifier end terminal
is extracted with sampling frequency of 1 kHz given as
input to the detection, classification and section discrimination module. In this work, severe AC faults are also
considered for section discrimination. Proposed method
uses fuzzy inference system (FIS) to carry out all relaying
task. The reach setting of the relay is 99.9% of the transmission line. Besides, the protection covers and discriminates the grounding fault with fault resistance up to 300 X.
Considering the results of the proposed method it can be
used effectively in real power network. |
