Study on Control Technology of VSC-HVDC in AC System Fault Mode

Article Preview

Abstract:

VSC-HVDC is usually associated with the AC system, which will be inevitably affected by AC system.VSC-HVDC mostly operates in the environment of strong current and high voltage, which will lead some parts of internal device to be interfered or damaged.This paper studies the control technology of VSC-HVDC in AC system fault mode to ensure that the device itself is not only perfect but timely rescue the AC system when it is necessary.
