5 FAQs about [Guam hvdc systems in smart grids]
What are the advantages of DC fault protection in Mt-HVDC grids?
The stated method for dc fault protection in MT-HVDC grids offers advantages such as robustness to noise, resilience to normal operation events, adaptability to varying sampling frequencies, fault detection at different distances, and suitability for DC transmission line faults.
How effective is S transform in VSC HVDC fault-location?
The technique capitalizes on the S transform's accuracy in determining the first arrival time of current frequency components and showcases reliable performance even in the presence of high fault resistance and noise, establishing its effectiveness for fault-location in VSC HVDC systems.
How to detect DC faults in VSC-MTDC grids with PWM converters?
Ashouri et al. proposed a selective harmonic-based pilot protection scheme for detecting DC faults in VSC-MTDC grids with PWM converters, using the first carrier frequency harmonic (FCFH) currents. The scheme efficiently discriminates between internal and external faults, leveraging HHT for precise fault detection.
Why is fault current interruption more complex in HVDC systems?
Fault current interruption is more complex in HVDC systems because of the absence of a “natural” current zero-crossing [9, 10]. In addition, the fault current rises to very high values and it spreads to the entire system in a range of time of just a few milliseconds, as a result of the HVDC grid's low impedance .
How effective is Ann topology for fault location in HVDC systems?
Particularly noteworthy is the efficacy of the 18–14–4–1 ANN topology. The method's straightforwardness, resilience, and precision position it as a promising solution for fault location in HVDC systems, effectively addressing the complexities of modern power systems with escalating data volumes. 7.2.3.
