Zusammenfassung:The invention relates to a parallel multi-terminal high-voltage direct-current converter station control authority switching system and method. The method comprises: when a home terminal high-voltagedirect-current converter station needs to carry out control authority switching, whether a control authority switching request permission condition is satisfied is determined, and the control authority switching request permission condition at least comprises that a communication state between the home terminal high-voltage direct-current converter station and at least one of other high-voltage direct-current converter stations is normal; If the control authority switching request permission condition is met, the home terminal high-voltage direct-current converter station communicates with specific high-voltage direct-current converter stations of other terminals to realize control authority switching, and the specific high-voltage direct-current converter stations refer to high-voltage direct-current converter st
