摘要：
The transient voltage stability issue is a well known problem in Hunan power grid, which the simulation shows the three-phase fault occurred at 500kV transmission line in eastern Hunan will cause the voltage collapse hundreds of kilometers away in southern Hunan. With the newly constructed Ultra High Voltage DC (UHV-DC) line in operation at 2017, located at eastern Hunan, the simulation reveals that the voltage issue is getting worse. This paper proposes a Transient Voltage Stability Probing Method and studies the transient voltage stability issue of Hunan power grid with UHV-DC in 2017. This study identifies the transient voltage stability weakness in Hunan power grid and helps to optimize the location of dynamic reactive power compensator installation. The simulation shows it improves transient voltage stability in Hunan power grid noticeably.
