Enhancing Electrical Protection and Automated Control Systems for HVDC Auxiliary Services: A Comprehensive Study Case

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.
