In high-voltage direct current (HVDC) transmission systems, commutation failures can lead to severe transient overvoltage at the sending-end system, significantly impacting the safe and stable operation of renewable energy bases. Superconducting synchronous condensers (SSC) have recently garnered significant academic interest due to their potential in providing reactive power support. However, research on the application of SSC in HVDC transmission systems remains relatively scarce. To bridge this research gap, this paper investigates the support capability of SSC in HVDC systems by analyzing key evaluation indicators and the voltage variation principles during fault conditions. The simulation results demonstrate that the SSC effectively reduces voltage dips at the initial stage of faults, suppresses overvoltage caused by current-limiting operations, and prevents system instability, thereby accelerating the restoration of grid stability.

摘要

In high-voltage direct current (HVDC) transmission systems, commutation failures can lead to severe transient overvoltage at the sending-end system, significantly impacting the safe and stable operation of renewable energy bases. Superconducting synchronous condensers (SSC) have recently garnered significant academic interest due to their potential in providing reactive power support. However, research on the application of SSC in HVDC transmission systems remains relatively scarce. To bridge this research gap, this paper investigates the support capability of SSC in HVDC systems by analyzing key evaluation indicators and the voltage variation principles during fault conditions. The simulation results demonstrate that the SSC effectively reduces voltage dips at the initial stage of faults, suppresses overvoltage caused by current-limiting operations, and prevents system instability, thereby accelerating the restoration of grid stability.
