Summary
This paper presents a comprehensive case study examining protection and automation strategies for High Voltage Direct Current (HVDC) auxiliary systems, which are critical to ensure overall system reliability. The emphasis is on power supply redundancy and advanced fault isolation techniques, using Automatic Transfer Schemes (ATS), zone-selective interlocking (ZSI), and the integration of protection functions with operational requirements.

Key design aspects include transfer initiation criteria, ATS sequences and logic-based protections via GOOSE messaging, protection functions integrated within the scheme, switchgear considerations, and testing and commissioning practices.
