چکیده

Existing mechanical HVDC breakers are capable of interrupting HVDC currents within several tens of milliseconds, but this is too slow to fulfill the requirements of a reliable HVDC grid. HVDC breakers based on semiconductors can easily overcome the limitations of operating speed, but generate large transfer losses, typically in the range of 30 percent of the losses of a voltage source converter station.

Requirements for Fault Protection in HVDC Grids

Conventional Voltage Source Converters (VSC) cannot interrupt DC fault currents and DC circuit breakers are not yet commercially available for HVDC power ratings. Thus, the protection of VSC-HVDC systems is still an obstacle for the development of this technology. The features of VSC-HVDC systems make them suitable for implementing HVDC grids. Nevertheless, HVDC grids are more complex than poin...

Review of HVDC Circuit Breakers Topologies

Voltage Source Converter-High Voltage Direct Current (VSC-HVDC) is the most efficient and reliable method for electrical power transmission over long distances. The greatest challenge with VSC-HVDC system is that short-circuit faults damages the converter valves and the transmission network. The fault clearing time for the available DC breakers are not fast enough and reliable to provide adequa...

Analysis of Transient Fault Currents in Multi-Terminal HVDC Networks during Pole-to-Ground Faults

The fault current development in a circuit breaker during a pole-to-ground fault is analyzed for a generic multiterminal HVDC system based on Voltage Source Converters. The paper aims to contribute to the current discussion of which requirements on breaking time and peak current HVDC circuit breakers need to fulfill in such networks either based on OHLs or cables. Therefore, the fault current i...
