Abstract: In view of such frequent alarm-triggering failures as DC bus overvoltage reported by the signal system of Haizhu Square Station of Guangzhou Metro Line 6 after the transformation into UPS parallel operation, this paper provides an in-depth analysis, demonstrates the causes, and puts forward a solution of such failures. It also summarizes the matters needing attention in the transformation into UPS parallel operation, with a view to providing reference for peers in various cities.

Key words: UPS parallel operation, DC bus, overvoltage
